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; ?>

wordpress Prevent CSS Caching

by in , 0

WordPress:

<link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); echo '?' . filemtime( get_stylesheet_directory() . '/style.css'); ?>" type="text/css" media="screen" />

bbPress:

<link rel="stylesheet" href="<?php bb_stylesheet_uri(); echo '?' . filemtime( bb_get_active_theme_directory() . '/style.css'); ?>" type="text/css" media="screen" />

Adds stylesheet with time of last update. If the number changes the browser updates the CSS instead of using cached version. Easily amended to be none WP specific.

wordpress Paginate Custom Post Types

<?php 
  $temp = $wp_query; 
  $wp_query = null; 
  $wp_query = new WP_Query(); 
  $wp_query->query('showposts=6&post_type=news'.'&paged='.$paged); 

  while ($wp_query->have_posts()) : $wp_query->the_post(); 
?>

  <!-- LOOP: Usual Post Template Stuff Here-->

<?php endwhile; ?>

<nav>
    <?php previous_posts_link('&laquo; Newer') ?>
    <?php next_posts_link('Older &raquo;') ?>
</nav>

<?php 
  $wp_query = null; 
  $wp_query = $temp;  // Reset
?>

wordpress Output Excerpt Manually

by in , 0

There is always the_excerpt(), but that does some pretty specific stuff (e.g. adding paragraph tags, adding [...], not respect the more comment, use the saved excerpt...). Advanced Excerpt is pretty good at customizing that.

If you want to get real simple though:

<?php 
  $content = get_the_content(); 
  echo substr(strip_tags($content), 0, 130) . '...'; 
?>
