It is helpful to post your entire filter and callback code, rather than just pieces. But, I suspect that the problem is that you’re not returning $the_content outside of your conditional, e.g.: function magicalendar_get_event_page( $content ) { if ( $post->post_name == ‘magicalendarpage’ ) { // Do something to $content return $content; } } add_filter( ‘the_content’, … Read more
Actually you just need a callback for the body_class filter. Then simply check what correlation you got between your meta data and the actual value: If it is a 1:1 correlation, you can just add the result of get_field() as new body class. Example: array( get_field( ‘mem_id’ ) ) if the mem_id meta value would … Read more

The filter to do this is dynamic_sidebar_params also see this tutorial on this filter at ACF’s site (even if you don’t use ACF). function prefix_filter_widget_title_tag( $params ) { $params[0][‘before_title’] = ‘<h2 class=”widget-title widgettitle”>’ ; $params[0][‘after_title’] = ‘</h2>’ ; return $params; } add_filter( ‘dynamic_sidebar_params’ , ‘prefix_filter_widget_title_tag’ );
Within the WP::parse_request() method (src) we locate the query_vars filter: $this->public_query_vars = apply_filters( ‘query_vars’, $this->public_query_vars ); and within WP::register_globals() we can see why it becomes globally accessible (src): // Extract updated query vars back into global namespace. foreach ( (array) $wp_query->query_vars as $key => $value ) { $GLOBALS[ $key ] = $value; } where the … Read more
The gettext filter can be used to change strings that use the gettext functions. add_filter( ‘gettext’, ‘wpse_change_error_string’, 10, 3 ); /** * Translate text. * * @param string $translation Translated text. * @param string $text Text to translate. * @param string $domain Text domain. Unique identifier for retrieving translated strings. * * @return string */ … Read more
The simplest answer is as follows: add_filter( ‘private_title_format’, function ( $format ) { return ‘%s’; } ); It uses the private_title_format to change the format of the title to just the post title, without any unnecessary classes or functions.
I don’t know if one is faster or slower than the other, but I would suggest that using apply_filters() is the better approach, because it is cleaner, and more intuitive (in the sense of doing things the “WordPress way”). EDIT If you’re doing comparison tests, shouldn’t you compare the time required to execute the following: … Read more
A Replica Of The Name Column In WP_Users_List_Table I think we’ll have to remove the current Name column and add in our own column instead. Here are the steps: Step #1 First we add in our own custom Name column and then remove the default Name column. Here I use the array slicing trick, mentioned … Read more
The following bit of code adds a class to the first paragraph output by the_content: function first_paragraph($content){ return preg_replace(‘/<p([^>]+)?>/’, ‘<p$1 class=”intro”>’, $content, 1); } add_filter(‘the_content’, ‘first_paragraph’); Add the above to your theme’s functions.php file. Then in your CSS add something like: p.intro { font-weight:bold; } I can’t claim credit for this solution (see this thread … Read more
