?>wordpress Turn on WordPress Error Reporting
Comment out the top line there, and add the rest to your wp-config.php file to get more detailed error reporting from your WordPress site. Definitely don't do this live, do it for local development and testing.
// define('WP_DEBUG', false);
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);
@ini_set('display_errors', 0);wordpress Turn On More Buttons in the WordPress Visual Editor
These buttons (like one for adding an <hr> tag) aren't there by default in the WordPress visual editor, but you can turn them on pretty easily. This is code for your active theme's functions.php file, or make a functionality plugin.
function add_more_buttons($buttons) {
$buttons[] = 'hr';
$buttons[] = 'del';
$buttons[] = 'sub';
$buttons[] = 'sup';
$buttons[] = 'fontselect';
$buttons[] = 'fontsizeselect';
$buttons[] = 'cleanup';
$buttons[] = 'styleselect';
return $buttons;
}
add_filter("mce_buttons_3", "add_more_buttons");wordpress Spam Comments with Very Long URL’s
Super long URL's are a sure fire sign the comment is spammy. This will mark comments with URL's (as the author URL, not just in the text) longer than 50 characters as spam, otherwise leave their state the way it is.
<?php
function rkv_url_spamcheck( $approved , $commentdata ) {
return ( strlen( $commentdata['comment_author_url'] ) > 50 ) ? 'spam' : $approved;
}
add_filter( 'pre_comment_approved', 'rkv_url_spamcheck', 99, 2 );
