If you want to return a value in your hook, use apply_filters instead of do_action, like: $project_option .= ‘<ul class=”project-list”>’; foreach( $projects as $project ) { $project_id = $project->ID; $project_option .= ‘ <li class=”project” id=”project-‘ . $project_id . ‘”> <span class=”project-title”>’ . get_the_title( $project_id ) . ‘ </span> <span class=”project-status-title”>’ . __( ‘Project Status: ‘, … Read more
Performance impact of hooked functionality is determined by how often hook fires and how intensive the operation is. init only ever fires one per load, so multiple runs are not a factor for it. Mostly the thing you need to pay attention to is context. If your logic fires on every load and result is … Read more
…if it’s a good practice to load the main theme styles this way, since usually they’re hardcoded into the header before anything else. Long story short, yes. WordPress advocates the enqueue “API” for all assets whenever possible.
OK, sorry I understand. I can only assume that the plugins are shipping with “default help text”, because plugin_name_hook is just placeholder text for whatever the plugins – specific – do_action is called.
Ever since the solution mentioned here, WP has been updated and now allows you to manipulate the save process of wp_insert_post. If you look at the lines 3035 to 3057 (WP 4.7) the result of the check for empty title and content is stored in $maybe_empty. This variable is then run through a filter called … Read more
Assuming that your post_meta is being properly added, that the post in question is a real post, and that the value of ‘nb_postredirect’ is a good URL, I’d try: function nb_checkredirect( $post ) { //don’t have to use get_post_meta!* if ( $post->nb_postredirect ) { wp_redirect( $post->nb_postredirect ); exit; } } add_action( ‘the_post’, ‘nb_checkredirect’ ); Tested … Read more
In general you can deregister the action’s callback, after it’s been registered and then register your own before it’s invoked with do_action( ‘…’ ). Here’s an example: // Add your own with later priority, e.g. 11 or wrap it in another later hook: add_action( ‘amp_post_template_head’, ‘wpse_amp_post_template_add_canonical’, 11 ); function wpse_amp_post_template_add_canonical( $amp_template ) { // Remove … Read more
Generally, they will return the same URL, as bloginfo( ‘url’ ) will call home_url internally with any arguments, and the default first argument ($path) of home_url is the empty string. However, bloginfo( ‘url’ ) will apply an additional filter to it, namely the home_url filter. Common pratice is to use home_url, indeed with esc_url (even … Read more
The filter you are looking for is save_post. This filter is triggered each time you save a post. add_action( ‘save_post’, ‘my_function’ ); function my_function( $post_id ){ // Do your stuff here } This filter passes the post’s ID to the callback function, so you have access to everything you need.
Modify the following code I have added action in it. $(‘#btnDoCalculation’).click(function(e){ var formData = $(‘#interest_calculator’).serialize(); $.ajax({ type: ‘POST’, url: ‘<?php echo admin_url(‘admin-ajax.php’);?>’, data:formData, dataType: ‘json’, action:calculate_investor_interest encode:true, }).done(function(data){ if(data.success){ console.log(data); var results = data.calc_results; var newData = results.reduce(function(collection, element){ var rowData = {}; //create a new empty row element.reduce(function(collection, element){ //put the elements into the … Read more
