Problems with you code: You don’t need to check for $pagenow, that action will only fire in the Plugins screen. The action takes two arguments, present in your callback function, but absent in the action declaration. If you had WP_DEBUG enabled, you’d have seen the notice. An action hook doesn’t return values, you do your … Read more
Yes, it is possible. You can use the_content hook and assign your own filter to this hook. Then you should (that is the part when things get a little bit messy) parse and replace content of that post. So for example you can do it like so: function my_the_content_filter($content) { $content = str_replace(‘<h2 ‘, ‘<img … Read more
WooCommerce renders messages by using woocommerce_show_messages() function. This function is hooked to woocommerce_before_single_product action. So if you don’t want to render messages before single product, you need to remove that hook for the action. remove_action( ‘woocommerce_before_single_product’, ‘woocommerce_show_messages’ ); If you want to render messages in another place, then just call woocommerce_show_messages() function in desired place.
Sometimes you want to run some code before deciding to add an action, or a filter. This may involve checking the user’s permissions, checking the type of page request, checking whether another plugin is active etc. Some of those checks may not be possible until some way through WordPress’ execution – so it’s reasonably common … Read more
WP doesn’t “look” at the type of data you have, it just has a default of CHAR. So if you dump your current query you will see respective type cast: CAST(wp_postmeta.meta_value AS CHAR). To make it work you need to specify type argument explicitly ‘type’ => ‘NUMERIC’ and CAST will change accordingly: CAST(wp_postmeta.meta_value AS SIGNED). … Read more
Filters should be returned even if your condition fails. You are currently just returning the output when your condition is met, not when it fails. return $string; at the end of each function should solve your issue. EXAMPLE add_filter(‘wpseo_canonical’, ‘listpagecanonical’); function listpagecanonical($string) { if (is_page(1)){ //I do my stuff here return ‘http://canonicalurl.com’ } return $string; … Read more
TLDR; Nested shortcodes cannot have the same name. You must have unique names for shortcodes within shortcodes. I’ve found the answer thanks to @patnz in response to: shortcode inside another shortcode. If you look at the WordPress Codex :: Shortcode API :: Nested Shortcodes you will find the answer with an illustrative example. So in … Read more
Well thank you for this question i did this after you posted this function category_title( $title ){ if( is_category(‘name1’) ){ $title=”name1 title”; }elseif( is_category(‘name2’) ){ $title=”name2 title”; } return $title; } add_filter( ‘get_the_archive_title’, ‘category_title’ ); Hope this helps
You can use pre_get_posts action to modify this order. Here’s the code: function my_change_posts_order( $query ){ if ( ! is_admin() && ( is_category() || is_tag() ) && $query->is_main_query() ) { $query->set( ‘order’, ‘ASC’ ); } }; add_action( ‘pre_get_posts’, ‘my_change_posts_order’); What we do here is: We’re adding our function that will modify params for WP_Queries We … Read more
The handle_upload hook is called after wp_handle_upload is run, and it sends in a named array consisting of ‘file’, ‘url’ & ‘type’. You could possibly use code like this to utilise it, depending on what you need to achieve: function process_images($results) { if( $results[‘type’] === ‘image/jpeg’ ) { // or /png or /tif / /whatever … Read more
