Remove URL from string PHP

by in 0

f I have a string that contains a url (for examples sake, we'll call it $url) such as;

$url = "Here is a funny site http://www.tunyurl.com/34934";
How do i remove the URL from the string? Difficulty is, urls might also show up without the http://, such as ;
$url = "Here is another funny site www.tinyurl.com/55555";

There is no HTML present. How would i start a search if http or www exists, then remove the text/numbers/symbols until the first space?

Change Default Text Selection Color by CSS

by in , 0

Whilst this CSS3 declaration might not be crucial to your project or design and yes it is not supported by all browsers, but it is a fantastic effect that really takes your design one step further.
Currently FireFox, Safari, Chrome and Opera support the text section attribute, and the browsers that don’t support it simply ignore the code so nothing will break, so it doesn’t really matter.
We have setup a demo which you can test out further down the page; we have used the Design Juices colours in the example.

Sticky notes CSS3

by in , 0


I’ve been working on a pretty cool wall-mounted status board as one of my projects at Fog Creek. It’s a webapp that runs on a vertically mounted LCD screen in our office. It displays a bunch of interesting information like tech support calls, staff vacations, tweets about FogBugz, and more.

I’ve been incrementally adding features and improving the UI whenever I have spare cycles. The other night, I decided to redesign the Kanban board widget, which is a list of the top N things that the customer team needs from engineering. I decided to go with a sticky note UI that mimics a real-life Kanban board, which typically consists of a giant white board filled with a bunch of sticky notes.

My initial design used the classic yellow sticky notes, which I thought looked pretty neat. I showed my co-worker Rich who suggested that we make the notes look like the FogBugz and Kiln notepads that are laying around the office. Awesome idea! Way better.

Related Posts sidebar with jQuery and CSS3 | Brighten up by Css series

by in 0

The other day we were wondering how we could show our visitors more of our works. It’s normal that in a blog older posts get forgotten and even if something might still be very interesting and relevant, it get’s lost under the pile of new stuff. So we decided to create something like a little widget that can be used to show related posts in any page. The main idea is to show a fixed list at the right side of the screen with some thumbnails sticking out. When the user hovers over the items, they slide out, revealing the title and two links, one for the related article itself and one for the demo. Additionally, we will have a shuffle button under the list. When pressed, the list gets randomly refreshed with related posts.
Before we use this, we of course, want to share it with you :)

PHP Detect URL Protocol - http vs https

by in 0

I've written a little function to establish the current site url protocol but I don't have SSL and don't know how to test if it works under https. Can you tell me if this is correct?

function siteURL()
{
    $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
    $domainName = $_SERVER['HTTP_HOST'].'/';
    return $protocol.$domainName;
}
define( 'SITE_URL', siteURL() );
Is it necessary to do it like above or can I just do it like?:
function siteURL()
{
    $protocol = 'http://';
    $domainName = $_SERVER['HTTP_HOST'].'/'
    return $protocol.$domainName;
}
define( 'SITE_URL', siteURL() );
Under SSL, doesn't the server automatically convert the url to https even if the anchor tag url is using http? Is it necessary to check for the protocol?

Thank you!

Draw a Vibrant Poster/Banner by CSS | Brighten up by Css series

by in , 0

CSS has come a long way in recent years, and with new browser support for a hand full of CSS3 properties we can begin to replicate design styles directly in the browser that beforehand were recently only possible in our design applications. Follow this walkthrough of the making of Circlicious, a vibrant and abstract digital poster design made purely of HTML and CSS.


View the CSS poster demo
The Circlicious poster art makes use of plenty of circular geometric shapes and features lots of transparency to add multiple levels to the design, giving the design that bright and crisp feel of typical vector artworks. Being a design that makes use of CSS3 properties, it’s only suited to the modern browsers of Firefox, Safari and Chrome.

Firefox, Safari & Chrome = Win. Opera… Meh. Internet Explorer… I wouldn’t even bother.

Mini Navigation Menu | Brighten up by Css series

by in , 0

As you have probably heard by now, CSS3 animations are a powerful tool, which enables you to create animations which run without the need of applying additional scripting to the page. What is even better, in the next generation of browsers we will have even more powerful tools, including 3D transformations (already present in Safari).
But what difference does it make for us today? At the moment only three browsers give you the ability to animate CSS properties – Chrome, Safari and Opera, which together take up only a small part of the browser market. Firefox is expected to soon join the club, and with the impending release of IE9, it suddenly makes sense to start leveraging this technique.

So today we are making something practical – a simple CSS3 animated navigation menu, which degrades gracefully in older browsers and is future-proofed to work with the next generation of browsers.

Adding a Meta Description to Blogspot

by in 0

 An important part of a good SEO is the implementation of meta tags, which are commonly located in the header of our website, that are being, in the same time, invisible to users visiting the site. Well, to be more succinct, these tags have only one purpose: to include information about the page such as author name, date, key word, description, title, among others.

However, here we will only mention one, which is the meta description in Blogger. This description will appear as a fragment in the search results and as a description when sharing on Google+, Facebook and other social networks. A clear and precise description increases the chances of getting more clicks or visits.

As we will work only on the Blogger platform, here I will leave a little guide to easily add a meta description.

Random Posts Widget to Blogspot

by in 0

 The Random Posts widget or gadget for Blogger will show random posts you have added to your blog that due to the natural structure of blogs, could get lost deep in your archives, as most new users join and pick up from the moment they join, and they never bother going back to one of your good posts.

One of the easiest way to give a new life to your older posts is to display them in a random order in your sidebar. In this tutorial, I will share how you can add a random posts gadget in a Blogger blog.

The advantages of this widget is that is loading pretty fast and shows thumbnails of your posts and how many comments they have received, as well. So, let's begin adding it!


How to add Random Posts Widget to Blogger


Step 1. From your Blogger Dashboard, Go to Layout, click on Add a Gadget 

random posts widget, random blogger

Step 2. Add a new HTML/JavaScript Gadget
random posts blogger

Step 3. Paste the following code in the empy HTML box:
<style>
#random-posts img{float:left;margin-right:10px;
width:65px;height:50px;background-color: #F5F5F5;padding: 3px;}
ul#random-posts {list-style-type: none;}
</style>

<ul id='random-posts'>
<script type='text/javaScript'>
var rdp_numposts=5;
var rdp_snippet_length=150;
var rdp_info='yes';
var rdp_comment='Comments';
var rdp_disable='Comments Disabled';
var rdp_current=[];var rdp_total_posts=0;var rdp_current=new Array(rdp_numposts);function totalposts(json){rdp_total_posts=json.feed.openSearch$totalResults.$t}document.write('<script type=\"text/javascript\" src=\"/feeds/posts/default?alt=json-in-script&max-results=0&callback=totalposts\"><\/script>');function getvalue(){for(var i=0;i<rdp_numposts;i++){var found=false;var rndValue=get_random();for(var j=0;j<rdp_current.length;j++){if(rdp_current[j]==rndValue){found=true;break}};if(found){i--}else{rdp_current[i]=rndValue}}};function get_random(){var ranNum=1+Math.round(Math.random()*(rdp_total_posts-1));return ranNum};

difference between jQuery .val() and .attr('value')?

by in 0

.val() works on all input type elements in a useful way, including <select>...even in the cases of <select multiple>, checkboxes, and radio buttons (in which .val() gets or sets an array of selected values not just a string).
So basically they serve different purposes, even though .attr('value') behaves the same in some situations, like textboxes. The preferred method is .val() to get consistent behavior everywhere.
Just for kicks, here's a lesser-known example for checkboxes that makes .val() handy:
<input name="mytest" type="checkbox" value="1">
<input name="mytest" type="checkbox" value="2">
<input name="mytest" type="checkbox" value="3">
<input name="mytest" type="checkbox" value="4">
You can do this:
$("input[name='mytest']").val([1, 2, 3]);
....which will check the first 3 boxes.

wordpress Shortcode in a Template

Shortcodes in WordPress are bits of text you can use in the content area to invoke some kind of function to accomplish certain tasks. For example, video embedding in WP 2.9+ uses the shortcode. You can write your own shortcodes, and plugins often offer their functionality via shortcodes as well.

But what if you want to use a shortcode from within a template instead of with the content of a Post/Page? You can invoke it with a special function:

<?php echo do_shortcode("[shortcode]"); ?>

wordpress Reset Admin Password Through Database

You'll need to be able to run SQL on that database, like for example, through phpMyAdmin.

wordpress Reset Admin Password in Database

by in , 0

Forget your admin password and don't have access to the email account it's under? If you can get access to phpMyAdmin (or anything you can run mySQL commands), you can update it there.

UPDATE `wp_users` SET `user_pass` = MD5( 'new_password_here' ) WHERE `wp_users`.`user_login` = "admin_username";

Just replace new_password_here with the new password and admin_username with the real admin accounts usename.

wordpress Remove Whitespace from Function Output

by in , 0

In WordPress, there are many functions which output things for you. For example, wp_list_pages() outputs a list of all your published pages. The HTML markup it spits out is pretty nicely formatted (meaning: has line breaks and indenting).

There are some circumstances where all that "whitespace" in the formatting is undesirable. Like 1) it's all the more characters to deliver and 2) closing "the gap" in older versions of IE.

If the function supports a way to return a string (rather than immediately echo it), you can use a regex to remove the space:

<?php
   echo preg_replace('/>\s+</m', '><', wp_list_pages('echo=0'));
?>

wordpress Remove the 28px Push Down from the Admin Bar

by in , 0

For your functions.php file:

  add_action('get_header', 'my_filter_head');

  function my_filter_head() {
    remove_action('wp_head', '_admin_bar_bump_cb');
  }

By default, if you are seeing the admin bar as a logged in WordPress user, CSS like this will be output in your head (output in the wp_head() function):

<style type="text/css" media="screen">
	html { margin-top: 28px !important; }
	* html body { margin-top: 28px !important; }
</style>

This is normally a good thing, as it doesn't cover parts of your site then with its fixed-position-ness. But it can also be weird if you use absolute positioning for things. As they will be different depending on if the bar is there or not. Using the code above to remove the bump CSS will make the bar cover the top bit of your site, but at least the positioning will be consistent.

wordpress Remove Paragraph Tags From Around Images

by in , 0

In case you want to have <img> in your content but not have them get "Auto P'd" like WordPress likes to do.

example of problem:

blah blah blah

<img src="monkey.jpg">

blah blah blah

turns into:

<p>blah blah blah</p>

<p><img src="monkey.jpg"></p>

<p>blah blah blah</p>

We can fix it with this:

function filter_ptags_on_images($content){
   return preg_replace('/<p>\s*(<a .*>)?\s*(<img .* \/>)\s*(<\/a>)?\s*<\/p>/iU', '\1\2\3', $content);
}

add_filter('the_content', 'filter_ptags_on_images');

For your functions.php file, or, see Reference URL for a plugin. With this in place, we get:

<p>blah blah blah</p>

<img src="monkey.jpg">

<p>blah blah blah</p>

... meaning things like floating the images will be much easier.

wordpress Remove Admin Bar For Subscribers

by in , 0

You might want open registration on your WordPress site so that (for one small example) people can log in and leave comments on things without needing to type their name/url/email every time. But these users probably don't need to see the whole top admin bar as there likely isn't much use in it for them. Although do be sure to provide a link to edit their profile and log out.

This would be for your functions.php file or functionality plugin:

add_action('set_current_user', 'cc_hide_admin_bar');
function cc_hide_admin_bar() {
  if (!current_user_can('edit_posts')) {
    show_admin_bar(false);

wordpress Recent Posts Function

by in , 0

Technique #1

This function is useful when you need to display content, excerpt, custom fields, or anything related to the post beyond it's link and title. If you just need a list of linked titles, see the next technique. Put the following function in functions.php

function recent_posts($no_posts = 10, $excerpts = true) {

   global $wpdb;

   $request = "SELECT ID, post_title, post_excerpt FROM $wpdb->posts WHERE post_status = 'publish' AND post_type='post' ORDER BY post_date DESC LIMIT $no_posts";

   $posts = $wpdb->get_results($request);

   if($posts) {

               foreach ($posts as $posts) {
                       $post_title = stripslashes($posts->post_title);
                       $permalink = get_permalink($posts->ID);

                       $output .= '<li><h2><a href="' . $permalink . '" rel="bookmark" title="Permanent Link: ' . htmlspecialchars($post_title, ENT_COMPAT) . '">' . htmlspecialchars($post_title) . '</a></h2>';

                       if($excerpts) {
                               $output.= '<br />' . stripslashes($posts->post_excerpt);
                       }

                       $output .= '</li>';
               }

       } else {
               $output .= '<li>No posts found</li>';
       }

   echo $output;
}

Usage

After you've made the function. Put the following in the sidebar or wherever you like the recent posts to list..

<?php recent_posts(); ?>

You can give it 2 arguments, the first is the number of posts and the second is whether or not you want to display the excerpts. so recent_posts(2, false) will display the 2 most recent post titles.

Technique #2

<?php wp_get_archives( array(

    'type'            => 'postbypost',   // or daily, weekly, monthly, yearly
    'limit'           => 10,   // maximum number shown
    'format'          => 'html',   // or select (dropdown), link, or custom (then need to also pass before and after params for custom tags
    'show_post_count' => false,    // show number of posts per link
    'echo'            => 1     // display results or return array

) ); ?> 

Technique #3

More succinct version of #1, which also includes a more standardized query string.

<?php
   $recentposts = get_posts('numberposts=12&category=4');
   foreach ($recentposts as $post) :
       setup_postdata($post); ?>
       <li><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></li>
<?php endforeach; ?>

This is a direct edit to a core file: /wp-includes/query.php Note the plus signs in the above code indicate new lines to add.

Author Notes:

A client wanted me to setup a custom field called "Guide Rank" which allowed them to assign #1 - 20 for a list of Bars they were posting about.

After running the posts query I found that the meta_value was being treated as a string and as such the sort order was jumbled:

eg. 1, 10, 2, 3css-tricks.comC 7 , 8 , 9

To get WordPress/MySQL to use "Natural Sort Order" you just need to apply +0 to the field name and it'll be treated as a number (eg. meta_value+0).

So that existing behavior is not interrupted I've just added the new type 'meta_value_num'.

My query line now looks like:

$guide_posts = new WP_Query("cat=12&meta_key=guide_rank&orderby=meta_value_num&order=ASC&showposts=10");

Which returns: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

This is up for inclusion in the WordPress trunk - so hopefully once it gets applied there should be no need for manually editing the file.

wordpress List Posts, Highlight Current

by in , 0

WordPress lacks a wp_list_posts() function that might seem logical go with the robust and useful wp_list_pages() function. You can simulate it though, by using the get_posts() function and running your own loop through the results.

The parameters for get_posts() below are just examples, replace with your needs.

<ul>

    <?php
        $lastposts = get_posts('numberposts=5&orderby=rand&cat=-52');
        foreach($lastposts as $post) :
        setup_postdata($post); ?>

        <li<?php if ( $post->ID == $wp_query->post->ID ) { echo ' class="current"'; } else {} ?>>
            
            <a href="<?php the_permalink() ?>"><?php the_title(); ?></a>
            
        </li>

    <?php endforeach; ?>

</ul>

wp_list_pages() also has the feature of adding a class name of "current_page_item" to the list element when that page is the active one. Notice the opening list tag above, which replicates that functionality by seeing if the ID from the current query matches the ID from the current iteration of the loop.

wordpress Insert Images within Figure Element from Media Uploader

by in , 0

For your functions.php file or a functionality plugin:

function html5_insert_image($html, $id, $caption, $title, $align, $url) {
  $html5 = "<figure id='post-$id media-$id' class='align-$align'>";
  $html5 .= "<img src='$url' alt='$title' />";
  if ($caption) {
    $html5 .= "<figcaption>$caption</figcaption>";
  }
  $html5 .= "</figure>";
  return $html5;
}
add_filter( 'image_send_to_editor', 'html5_insert_image', 10, 9 );

It also takes what you enter as a caption and inserts it within the <figure> tag as a <figcaption>. Example inserted code:

<figure id='post-18838 media-18838' class='align-none'>
  <img src='http://youresite.com/wp-content/uploads/2012/10/image.png' alt='Title of image'>
  <figcaption>Caption for image</figcaption>

wordpress If Page Is Parent or Child

by in , 0

There are built in conditional WordPress functions for testing for a page:

if ( is_page(2) ) {
  // stuff
}

Or for testing if a page is a child of a certain page:

if ( $post->post_parent == '2' ) {
  // stuff
}

But there is no built in function that combines these two things, which is a fairly common need. For example, loading a special CSS page for a whole "branch" of content. Like a "videos" page and all its children individual videos pages.

This function (add to functions.php file) creates new logical function to be used in this way:

function is_tree($pid) {      // $pid = The ID of the page we're looking for pages underneath
	global $post;         // load details about this page
	if(is_page()&&($post->post_parent==$pid||is_page($pid))) 
               return true;   // we're at the page or at a sub page
	else 
               return false;  // we're elsewhere
};

Usage

if (is_tree(2)) {
   // stuff
}

wordpress ID the Body Based on URL

by in , 0

<?php
	$url = explode('/',$_SERVER['REQUEST_URI']);
	$dir = $url[1] ? $url[1] : 'home';
?>

<body id="<?php echo $dir ?>">

This would turn http://domain.tld/blog/home into "blog" (the second level of the URL structure). If at the root, it will return "home".

Here is an alternate method:

<?php
       $page = $_SERVER['REQUEST_URI'];
       $page = str_replace("/","",$page);
       $page = str_replace(".php","",$page);
       $page = str_replace("?s=","",$page);
       $page = $page ? $page : 'index'
?>

This would turn http://domain.tld/blog/home into "domaintldbloghome", which is far more specific. It also will remove ".php" file extensions and the default WordPress search parameter.

More Secure Method

function curr_virtdir($echo=true){
        $url = explode('/',$_SERVER['REQUEST_URI']);
        $dir = $url[1] ? $url[1] : 'home'; // defaults to this if in the root
        $dir = htmlentities(trim(strip_tags($dir))); // prevent injection into the DOM through this function
        if ($echo) echo $dir;
        return echo $dir; // ie. curr_virtdir(false)
}
function get_curr_virtdir(){
        curr_virtdir(false);
}

Returns the "middle" directory value:

On http://css-tricks.com it would return "home"
On http://css-tricks.com/snippets it would return "snippets"
On http://css-tricks.com/forums/viewforum.php?f=6 it would return "forums"

The strip_tags() and htmlentities() functions prevent malicious code from being insterted into the URL and ran, e.g.

<body id="foo"><script>alert("Booo");</script>

Usage for IDing the body:

<body id="<?php curr_virtdir(); ?>">

Other usage:

<?php
  if ( get_curr_virtdir() == "store" ){
    echo "Welcome to our awesome store !";
  } elseif ( get_curr_virtdir() == "home" ){
    echo "Welcome home :-)";
  } else {
    echo "Welcome on some other page";
  }
?>

wordpress HTML5 Shim in functions.php

by in , 0

Might as well keep your header.php clean and insert the shim from the functions.php file.

// add ie conditional html5 shim to header
function add_ie_html5_shim () {
    echo '<!--[if lt IE 9]>';
    echo '<script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script>';
    echo '<![endif]-->';
}
add_action('wp_head', 'add_ie_html5_shim');

The shim is to enable HTML5 elements to be able to be styled through CSS in Internet Explorer versions less than 9.

wordpress Get The First Image From a Post

by in , 0

Let's say you wanted to use the post thumbnail feature of WordPress, but had a whole archive of posts that would take too much time to go through. For new posts, you can be specific and use the feature as intended. For old posts, you just want to use the first image it finds in the content for the thumbnail, or a default if none present.

Add this to functions.php or make a functionality plugin:

function catch_that_image() {
  global $post, $posts;
  $first_img = '';
  ob_start();
  ob_end_clean();
  $output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
  $first_img = $matches[1][0];

  if(empty($first_img)) {
    $first_img = "/path/to/default.png";
  }
  return $first_img;
}

To use it, use this code in the loop:

if ( get_the_post_thumbnail($post_id) != '' ) {

  echo '<a href="'; the_permalink(); echo '" class="thumbnail-wrapper">';
   the_post_thumbnail();
  echo '</a>';

} else {

 echo '<a href="'; the_permalink(); echo '" class="thumbnail-wrapper">';
 echo '<img src="';
 echo catch_that_image();
 echo '" alt="" />';
 echo '</a>';

}

I found that has_post_thumbnail wasn't as reliable as the logic above.

wordpress Get ID from Page Name

function get_ID_by_page_name($page_name) {
   global $wpdb;
   $page_name_id = $wpdb->get_var("SELECT ID FROM $wpdb->posts WHERE post_name = '".$page_name."' AND post_type = 'page'");
   return $page_name_id;
}

Now you can use this function in templates when you need an ID of a specific post/page and all you have is the name.

wordpress Get Featured Image URL

by in , 0

Post thumbnails are pretty useful and pretty easy to use in WordPress. Simply add:

add_theme_support('post-thumbnails'); 

To a theme's functions.php file and you'll get a Featured Image module on the admin screen for posts which allows you to select one.

It is also very easy to output that image as an HTML <img>:

the_post_thumbnail();

But what if you just need the URL? Say, you're going to use it as a background-image on an element rather than a content image. Unfortunately there is no super easy/obvious function for that.

Within the loop, you'll have to do:

$thumb_id = get_post_thumbnail_id();
$thumb_url_array = wp_get_attachment_image_src($thumb_id, 'thumbnail-size', true);
$thumb_url = $thumb_url_array[0];

Then $thumb_url will be that URL.

wordpress Get Content by ID

    return $page_data->post_content;
  }
  else return false;

wordpress Find ID of Top-Most Parent Page

This will find what the ID is of the top-most parent Page, in a nested child page. For example, this page you are literally looking at is nested under

<?php

if ($post->post_parent)	{
	$ancestors=get_post_ancestors($post->ID);
	$root=count($ancestors)-1;
	$parent = $ancestors[$root];
} else {
	$parent = $post->ID;
}

?>

$parent will be the correct ID. For example, for use with wp_list_pages.

wordpress Dump All Custom Fields

by in , 0

WordPress has a built in function, the_meta(), for outputting all custom fields. But this function is limited in that it doesn't always output all of them. For example, it misses custom fields added by plugins which begin with an _ underscore.

This bit of code uses an alternate function, get_post_custom() which will return all of them, and display all values. Good for debugging.

<h3>All Post Meta</h3>

<?php $getPostCustom=get_post_custom(); // Get all the data ?>

<?php
    foreach($getPostCustom as $name=>$value) {

        echo "<strong>".$name."</strong>"."  =>  ";

        foreach($value as $nameAr=>$valueAr) {
                echo "<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
                echo $nameAr."  =>  ";

The image that shows for the author comes from the email address set for that user which goes to a corresponding Gravatar. The display name and bio come from the User settings area in the Admin.

That should be all the CSS hooks you need to style up the area however you want. Note: some of these functions are WordPress 2.8 and newer only.
