I’d say there is barely enough information in the question to speculate on an answer but it sounds like to me that… If your data is saved in individual key/value pairs then delete_post_meta will do it. You would pass the function a post ID and a key name: delete_post_meta(1,’keyname’);. It will delete the whole key/value … Read more
First of all – I assume the $search variable is being populated from $_GET (it’s not in your code). Secondly, do you need the % ? I think using LIKE with wp_query doesn’t require them.
When using the == comparison, it compares the values at the same type. So 1 is equal to “1”, and true. Likewise, 0 is equal to false. Taking a deeper look into the return values of get_post_meta, we can see that using the $single=true 3rd argument returns a blank string (”) when no value is … Read more
UPDATE Ok, thanks to all for helping me out and pointing me in the right direction. I do have some code clean up to do and a possible all out change in code but I’ll use this for now. I got it to work with the following code. //El display image function el_display(){ global $post; … Read more
Your code is setting the slug of the post to your custom meta string. That work is done on the admin side and so shouldn’t effect your viewers much. WordPress will use that slug more or less directly to construct an url and/or load a page. What you have done is not different from hand-writing … Read more
your nonce action name is wrong use same as entered in wp_nonce_field(‘update_grn_data’,’grn_data’); and also you forget to echo nonce, try this if ( isset( $_POST[‘grn_data’] ) && wp_verify_nonce($_POST[‘grn_data’],’update_grn_data’) ) { //if nonce check succeeds. $postid = $_POST[‘post_id’]; $data = $_POST[‘grn’]; update_post_meta($postid,’grn’,$data); } form <?php /* This file is to provide input fields to record data … Read more
It seems you are only searching the meta with $search. You need to also pass $search to s. $args[‘s’] = $search Here’s a similar question. Search that will look in custom field, post title and post content
This is because save_post hook function accepts post id as parameter and not post object so the save_custom_meta function should be as following. /** Save the Data **/ function save_custom_meta($post_id) { // verify nonce if (!wp_verify_nonce($_POST[‘shortdesc_meta_box_nonce’], basename(__FILE__))) return $post_id; // check autosave if (defined(‘DOING_AUTOSAVE’) && DOING_AUTOSAVE) return $post_id; // check permissions if (!current_user_can(‘edit_post’, $post_id)) return … Read more
You have two issues: 1.- Your are not passing the correct post ID.

Unfortunately it is not possible to modify the field to use the name instead of ID and to keep the AJAX functionality. You could use a standard select field, and pass the post data in the desired format to this – although you will loose the AJAX functionality. The only way to achieve 100% of … Read more
