WordPress Walkers aren’t using constructors. They are started up with walk() method which is passed arguments as third argument (confusingly not reflected in method signature). You can capture it into your object’s property with something like this: class Args_Walker extends Walker { public function walk( $elements, $max_depth ) { // we could declare above, but … Read more
Adding a NOT EXISTS clause should force LEFT JOINs: ‘meta_query’ => array( ‘relation’ => ‘OR’, array(‘key’ => ‘file_gallery’, ‘value’ => ‘1’, ‘compare’ => ‘!=’), array(‘key’ => ‘file_gallery’, ‘compare’ => ‘NOT EXISTS’), ),
You cannot do this with the default paginate_links() functions. Looking at the source code, there are no filters from which you can change the layout as you wish ALTERNATIVE SOLUTIONS Although you cannot do this by default, it doesn’t mean that you cannot get your desired output. Here is a couple of options to explore … Read more
Thanks for the response David. I found the solution. I added the following code in functions.php add_filter(‘get_the_excerpt’, ‘process_excerpt’); function process_excerpt($param) { global $post; if(in_category(‘MY-CATEGORY-SLUG’,$post)) return ‘adding some data’.$param; else return $param; } This fixed my issue.
If you take a look in source the condition for this message is get_option(‘require_name_email’). You can control it in Settings > Discussion > Comment author must fill out name and e-mail. The programmatic way could be add_filter( ‘pre_option_require_name_email’, ‘__return_null’ );
Here’s a slightly modified version of your code snippet: add_action( ‘login_head’, [ ‘WPSE_Admin’, ‘plugin_setup’ ] ); class WPSE_Admin { public static function plugin_setup() { add_filter( ‘login_headerurl’, [ ‘WPSE_Admin’, ‘the_logo_url’ ] ); } public function the_logo_url() { return get_bloginfo(‘url’); } } The filter callbacks must be public, not private. The reason for this is that apply_filters()/apply_filters_ref_array() … Read more
Try this. First check if the original string length is less than or equal to passed in length, and if so, we ignore the $after parameter : function the_titlesmall($before=””, $after=””, $echo = true, $length = false) { $title = get_the_title(); if( strlen($title) <= $length ) $after=””; if ( $length && is_numeric($length) ) { $title = … Read more
I’m not sure how your current “hidden” checkbox code is working (there’s an undefined $archive variable, in_category might not fire correctly in the context, and I doubt your post type is actually your_post_type). Just to make sure we get everything working, here is a complete solution for adding a checkbox to the edit post screen, … Read more
WordPress only holds the hooks information in global $wp_filter so you can check if a hook is registered with some specified function or not. you can also use function has_filter. But I guess you can not check that, it has been called or not on some specific execution point. But you can do this with … Read more
Filtering gettext is horrible for performance. I would strongly recommend to try do it via any other approach. And if all else fails to add and remove filter with extreme precision around necessary parts. As for why it fails my educated guess would be — timing. It is quite common for strings to be centralized … Read more
