You can use the_content filter if you need to modify the content: add_filter( ‘the_content’, ‘cyb_content_filter_callback’ ); function cyb_content_filter_callback( $content ) { // Only for singular post views and for posts of main loop if( is_singular( ‘post’ ) && in_the_loop() ) { // modify $content here } return $content; } If you need an action that … Read more
The cron arg usage looks weird. The insert id will return garbage by the time your function is called. By the same token, I believe better schedule it always, with the id argument, on insert, if this if for logging. Else you’ll be throttling your logs, basically. Lastly, are you sure that wp_mail() is working?
That code must run before the wp_head hook fires or nothing will happen, and when tested in a mu-plugin file it does work. I suspect that you are trying to hook that function too late– perhaps from inside a theme template file after get_header (in most cases). Place that code in the theme’s functions.php or … Read more
How to check if an action is already fired? The did_action( $tag) function returns the number of times the $tag action hook has fired.
save_post gets fired, once the post is saved. We get the current post object as the second parameter. So we can check, if the current post status is trash: <?php add_action( ‘save_post’, function( $post_ID, $post, $update ) { if ( ‘trash’ === $post->post_status ) { return; } /** do your stuff **/ }, 10, 3 … Read more
pre_get_posts runs for every query. That includes the main query, secondary queries, and menus. The problem is that is_post_type_archive(array(‘provider’)) is checking if the main query is the post type archive, not a specific query going through pre_get_posts. So when you check for that and then modify the current query going through pre_get_posts you’re going to … Read more
Okay I solved this but don’t know it is right way or wrong way. Hope you expert will give some better guideline. What I did just added two function into my add_action function and use those as a wrapper. // adding and re arranging placement function q2a_product_summary() { function wrapstart () { echo ‘<div class=”buy-box”>’; … Read more
If you deactivate the plugin, the scheduled event will still try to run ( and fail ) unless you remove that event from the schedule using wp_clear_scheduled_hook
The issue here is that the child theme functions.php is loaded before the parent theme functions.php. Therefore, the ordering of the add/remove actions would be something like so: //* From the child theme remove_action( ‘wp_head’, ‘func’, 5 ); //* From the parent theme add_action( ‘wp_head’, ‘func’, 5 ); The callback to func on the wp_head … Read more
The publish_post post takes two arguments first is $ID of the post that is being published and the second is the $post instance (See codex). I modified your code a bit below. Your class is almost identical just renamed the parameters of the function to not cause confusion. class customClass{ function dothisfunction( $ID, $post ){ … Read more
