Indeed! It’s a filter called ‘the_content’, to which numerous other functions are hooked such as the one that turns WordPress into WordPress, oembeds, and the p tag wrapping echo apply_filter(‘the_content’,$data->the_content);
You can override it, but you’ll have to create Child-Theme versions of archive.php, attachment.php, and single.php. Since it’s a translation string, you might be able to do something hackish, like provide a en_US.MO file that translates “Filled under” as “Filed under” (or whatever you want). But that gets tricky – and This Theme appears to … Read more
You use preg_replace function incorrectly. This function returns replaced content: add_filter( ‘the_content’, ‘wpdu_image_replace’ ); function wpdu_image_replace( $content ) { return preg_replace( ‘/<img.*?src=”https://wordpress.stackexchange.com/questions/55241/(.*?)”.*?>/’, ‘<a href=”$1″>Image file</a>’, $content ); } Also pay attention that you don’t have to use global variable $post, because content of the post is passed to your function as first argument.
The class attribute contains the size in the format attachment-$size, you could do a check for a specific size like: if( strstr( $attr[‘class’], ‘thumb’ ) ): // size is attachment-thumb endif;
Your syntax is wrong, you’re mixing up the html and php function at the beginning. See Filter here – wp-includes/general-template.php#L151 I think we should return the form, instead of printing it, See my example, It should work, If you want to modify something, do it in function. Example – function savior_search(){ //Modify This $form = … Read more
I believe it’s a simple difference, here; you are echoing with e() – try returning with _() instead: function custom_title_text( $title ){ return __( ‘Enter Name here’ ); } add_filter( ‘enter_title_here’, ‘custom_title_text’ );
The problem is most probably, that you don’t actually call the filter. WordPress does this not automatically for you. If you want to create a custom filter you have to manually call apply_filters, so that the added filters get executed: function the_views($postID){ $count_key = ‘views’; $count = get_post_meta($postID, $count_key, true); if($count==”){ delete_post_meta($postID, $count_key); add_post_meta($postID, $count_key, … Read more
It is always global. add_filter() and add_action() are just wrapper for the global variable $wp_filter. So it doesn’t matter where the function is called. The same is true for apply_filters(), apply_filters_ref_array(), do_action_ref_array() and do_action(): they work in the global namespace, that’s the reason why the callback handlers (functions or methods) have to be public. A … Read more
Based on this Answer, it was easy. Result: Code: check the comments // ID of the post/page that we want a separate list of comments $the_id = ‘1’; add_action( ‘current_screen’, ‘wpse_73581_exclude_lazy_hook’ , 10, 2 ); /** * Delay hooking our clauses filter to ensure it’s only applied when needed. */ function wpse_73581_exclude_lazy_hook( $screen ) { … Read more
I don’t believe there’s anything automatic for what you’re looking for, no. I built a similar functionality for sorting products with dimensions, but this was all custom as I did not find anything that suited my needs. You’d need to look into pre_get_posts using $_GET requests.
