Edited again to demonstrate adding and removing filters: Include these general functions in your functions.php. These are the filters you will invoke for the loops where you want to limit your query by these two meta values: function date_check_join( $join ) { global $wpdb; $join .= ” JOIN “.$wpdb->postmeta.” AS startdate ON (“.$wpdb->posts.”.ID = startdate.post_id … Read more
Change your nonce verify to actually verify and update post meta, else do nothing. But don’t use exit at the top of your template. // top of page if ( isset( $_POST[‘drw_inventory’] ) && wp_verify_nonce($_POST[‘drw_inventory’],’update_drw_postmeta’) ) { //if nonce check succeeds. global $post; $postid = $post->ID; $data = $_POST[‘priceone’]; update_post_meta($postid,’metakey’,$data); } // in single.php $priceone … Read more
When you save an array as post meta, WordPress will serialize it to a string and save that string. Let’s take a simple array: array ( 1 => array ( ‘url’ => “https://wordpress.stackexchange.com/”, ‘title’ => ‘Home’ ), 3 => array ( ‘url’ => ‘http://wordpress.stackexchange.com/’, ‘title’ => ‘WordPress Stack Exchange’ ), 4 => array ( ‘url’ … Read more
The solution is using added_post_meta and updated_post_meta hook . Here is the working code . add_action( ‘added_post_meta’, ‘add_custom_field_automatically’, 10, 4 ); add_action( ‘updated_post_meta’, ‘add_custom_field_automatically’, 10, 4 ); function add_custom_field_automatically( $meta_id, $post_id, $meta_key, $meta_value ) { if ( ‘_my_meta_key’ == $meta_key ) { add_post_meta($post_id, ‘_my_new_meta_key’, $meta_value.’to something new’, true); } }
Short Answer: If you have properly validated the data, then sanitization can be made optional. Longer Answer User-supplied data and data from unknown/external sources should always be treated as untrusted even in the case where the user was actually yourself, so yes, we should always validate and/or sanitize such data. And therefore, no, please do … Read more
Does the unused postmeta affect the speed of my database? Anything in your database affects the speed of your database. The question is how much of a slowdown, and if the amount of data is significant enough. Unless your having a huge amount of metadata it will not affect the speed of your database very … Read more
add_meta_box should give you the box container like your have pictured. You have a select drop-down because that is what you created here: echo ‘<select name=”rating”>’; echo ‘<option value=””‘ . ((($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
