You do this: $item->content_multiple = get_post_meta($item->ID, ‘_menu_item_content_multiple’, true); Note how you set the third parameter of get_post_meta() to true, which means that only one value will be returned. If you read the docs, you will see that, if the third parameter is false, you will get an array with all the values for that meta … Read more
After a lot of messing around with this, I think I found a fairly good solution here. I realize this is over a year after you asked but this was bothering me and I couldn’t find a good solution until now. The problem is that the get_post_metadata function doesn’t allow you to access the current … Read more
This part of wp_insert_posts() gives it away: if ( ! empty( $postarr[‘meta_input’] ) ) { foreach ( $postarr[‘meta_input’] as $field => $value ) { update_post_meta( $post_ID, $field, $value ); } } where we see how the post meta fields are updated/added with update_post_meta(). Here’s the inline description for meta_input: Array of post meta values keyed … Read more
If you can explain it in SQL, you can query for it! There are three places where we want to change the default query: SELECT wp_posts.* FROM wp_posts INNER JOIN wp_postmeta ON (wp_posts.ID = wp_postmeta.post_id) WHERE 1=1 AND wp_posts.post_type=”post” AND (wp_posts.post_status=”publish”) AND wp_postmeta.meta_key = ‘startDate’ AND CAST(wp_postmeta.meta_value AS CHAR) < ‘2011-03-23’ GROUP BY wp_posts.ID ORDER … Read more
Each post meta key can have multiple values. So you get the values by default as an array; the first entry (0) is the oldest. get_post_custom() fetches all meta keys with their values. You could simplify your code with: $price = get_post_meta( $post->ID, ‘price’, TRUE ); $comake = get_post_meta( $post->ID, ‘coMake’, TRUE ); When the … Read more
As stated in @ambroseya’s answer, its supposed to work like that. Once you declare a meta query, even if you aren’t looking for a specific value, it will only query posts with that meta key declared. If you want to include all posts sort them by the meta key, use the following code: $args = … Read more
@s_ha_dum suggests that Post meta will be deleted automatically. Therefore because his reputation suggests he knows what he is talking about, this solution only handles Post attachments. I’d suggest checking out the docs for the before_delete_post() hook, as it’s quite handy to be able to check out what Post Type is being deleted, etc. add_action(‘before_delete_post’, … Read more
This should do it. The default relation is AND so that won’t need to be specified. $args = array( ‘post_type’ => ‘wpse_cpt’, ‘meta_query’ => array( array( ‘key’ => ‘post_code’, ‘value’ => ‘432C’, ), array( ‘key’ => ‘location’, ‘value’ => ‘XYZ’, ), ), ); $query = new WP_Query( $args );
Here’s one experimental idea: Assume we got: post A with the custom field location1 as UK – London post B with the custom field location2 as France – Paris post C with the custom field location3 as USA – New York Then we could use, for example: $args = [ ‘meta_query’ => [ ‘relation’ => … Read more
The underscore prefix are private, these meta fields will be hidden and will not be shown as custom fields in the post backend screens. Those meta fields without the underscore prefix are public fields and shows up as custom fields in the post screens
