Does the unused postmeta affect the speed of my database? Anything in your database affects the speed of your database. The question is how much of a slowdown, and if the amount of data is significant enough. Unless your having a huge amount of metadata it will not affect the speed of your database very … Read more
add_meta_box should give you the box container like your have pictured. You have a select drop-down because that is what you created here: echo ‘<select name=”rating”>’; echo ‘<option value=””‘ . ((($value == ”) || !isset($ratings[$value])) ? ‘ selected=”selected”‘ : ”) . ‘> Untouched </option>’; // output each rating as an option foreach ($ratings as $id … Read more
You’re using $term->ID. Taxonomy terms do not have an ID property. They have a term_id property: $display_type = get_term_meta( $term->term_id ); You’ll notice that WooCommerce is using this, while your attempts are not.
To update post meta that are an array: you have to fetch the original values, change the value you need and update it again. For example $list_of_values = get_post_meta($post_id, ‘_list_values’, true); if(!empty($list_of_values)) { $list_of_values[“some_prop”] = “new value”; } update_post_meta($post_id, ‘_list_values’, $list_of_values);
This works fine if I’m only returning data for a single meta key…but fails if I want to return all of the meta data, but return them all as strings (single). This doesn’t make a lot of sense. A function in PHP can only return a single value so there is no way to return … Read more
The issue is that for correct output WP needs to process date through date_i18n() function. When you use date format, hardcoded in PHP code (not simply saved in PHP DATE_* constant) like ‘c’ – it’s not available to your code and so for WP to process. System-wide fix would be to re-process date with analogous … Read more
Solved it! Used save_post to run push_notification() as well as to run the function save_post_meta() that saves my post meta. The problem occurred coz push_notification() gets fired before save_post_meta() due to which the meta wasn’t being saved and therefore it remained inaccessible. Just changed priorities of the functions to make it work like so : … Read more
I found this from just a Google search (Source) You have to change met value keys as you want. However, it is highly recommend to take a DB backup before running this code. <?php function delete_useless_post_meta() { global $wpdb; $table = $wpdb->prefix.’postmeta’; $wpdb->delete ($table, array(‘meta_key’ => ‘_edit_last’)); $wpdb->delete ($table, array(‘meta_key’ => ‘_edit_lock’)); $wpdb->delete ($table, array(‘meta_key’ … Read more
Depending on your theme, they may be hard coded into a sidebar or footer file. If this is the case, you will need to get your hands dirty and edit your theme files. But you can usually remove them by adding a widget, as these items often only show up when no widgets have been … Read more
If the wp_send_json() function is sending the right data, but for some reason you want to use another function to actually send the JSON data, then you can use wp_json_encode(). This is basically the only thing that wp_send_json() does before sending off the data. add_action( ‘publish_post’, ‘wpse_228607_publish_post’, 10, 2 ); function wpse_228607_publish_post( $post_id, $post ){ … Read more
