A var_dump() in save_post action doesn’t display any information on the screen. Well, it does only when you are on “Add new” screen. This is due the different sequence of actions that follow when creating a new post or when editing it. When you click on “publish” or “update” button, there is a request, the … Read more
I solved my own problem. save-post hooks in before the form is saved. It even gives us access to the $_POST object and allows us to interact with it before the original save happens. What this means essentially is that I’m overwriting my values with blank formdata. Rather than updating post meta, I’ve documented and … Read more
You can use the_content (Click here for more info) hook to change the content while rendering the post/page. This will be triggered when Post is being read from Database. So post content will not be changed in database but only filtered while rendering. add_filter( ‘the_content’, ‘remove_email_and_url_from_post’ ); function remove_email_and_url_from_post( $content ) { // Check if … Read more
Okay, so just in case anyone needs help on the same thing I did… here is my solution. Instead of a php/wordpress solution, I used javascript. Id love to see the php/wordpress solution if someone wants to post it. <?php // Admin Custom JS add_action(‘admin_head’, ‘admin_custom_js’); function admin_custom_js() { ?> <script> // update date (month) … Read more
You can add custom meta fields for doing so. Here, is sample code for adding a meta field for post type post. For more details please refer to link. <?php /************************************************************************/ function myPrice_meta_box() { add_meta_box(‘myPrice_field’, ‘Price’, ‘myPrice_meta_box_callback’, ‘post’, ‘normal’, ‘high’); } add_action(‘add_meta_boxes’, ‘myPrice_meta_box’); /** * Prints the box content. * * @param WP_Post $post The … Read more
Doing something like this would help make sure the theme object has been instantiated properly… global $theme_options; if ( (!isset($theme_options) || (!is_object($theme_options)) ) { $theme_options = new My_Theme_Options_Class(); }
When editing a post using the admin interface the wp-admin/post.php script redirects you after saving the post. This is done to avoid resubmitting the post request if you refresh the page after submitting. It also means that you’re not able to output anything during the save_post action. case ‘editpost’: check_admin_referer(‘update-post_’ . $post_id); $post_id = edit_post(); … Read more
As you can see from the hook order, widget_init is a hook that is quite early in the page execution order. So, by the time save_post is fired widget_init has already passed. If you add an action to a hook that has already passed, nothing will happen.
The problem is probably that the $post_id parameter passed to via the save_post_$post_type hook is not the same $post_id as the original post – it’s the $post_id of the temporary post that’s created when you edit a post. To confirm this: add_filter( ‘pre_post_update’, ‘wpse_pre_post_update’, 10, 3 ); add_filter( ‘save_post’, ‘wpse_save_post’, 10, 1 ); function wpse_pre_post_update( … Read more
Rather than hooking into init or wp_load, here is a snippet you can drop into functions.php or on a theme file. I put it behind a $_GET so that you can only hit it once and when you are ready. Something like https://domain.com/page/?update_post_meta // Hide it from the public if(isset($_GET[‘update_post_meta’])){ // Let’s query all of … Read more
