meta_query: check if number exists

I believe, more robust solution would be to allow multiple values of custom field ‘participants’. You can store like following add_post_meta($post_id,’participants’,’value1′); add_post_meta($post_id,’participants’,’value2′); add_post_meta($post_id,’participants’,’value3′); add_post_meta($post_id,’participants’,’value4′); Deletion would be like delete_post_meta($post_id,’participants’,’value1′); Query will then change to a simpler one. ‘meta_query’ => array( array( ‘key’ => ‘participants’, ‘value’ => $user_id, ‘compare’ => ‘=’, ), ) In case you … Read more

Get posts by language in Polylang plugin

If you use the query_post function, I think you can just add the ‘lang’ parameter: $args_menu = array ( … ‘lang’ => ‘it’, … ); See : http://wp.primacom.cz/en/enplugins/how-to-display-posts-only-in-one-language-in-polylang-plugin/

Conditional Tag for has post [closed]

I am not familiar with the plugin, but it seems unlikely that the $conditions array you’re adding to should contain any variety of WordPress query arguments. Further, referencing the $conditions array within a property that you’re setting on that very array won’t contain the new data you’ve added, but rather the array as it existed … Read more

Hooking to walker_nav_menu_start_el to insert list of subpages

I was able to solve my own problem by using get_the_title with the post ID rather than using the_title. Then I decided to try using $subpost->post_title and that worked too. I figure this is better than get_the_title since it doesn’t have to “get” the data again, it just uses the data we’ve already gotten. I … Read more

Output meta into arrays

Add ‘fields’ => ‘ids’ to skip setting up the post and just create the array you want in the foreach. $week_args = array( ‘posts_per_page’ => – 1, ‘post_type’ => ‘post’, ‘post_status’ => array( ‘publish’ ), ‘fields’ => ‘ids’, ‘date_query’ => array( ‘before’ => ‘next Saturday’, ‘after’ => ‘last Monday’, ), ); $week_array = get_posts( $week_args … Read more

How i can get post data from database when i am getting post id from url in wordpress

You may use $_GET parameter to get the id. $id = $_GET[‘id’]; Or try this: global $post; echo $post->ID; But it seems you have a problem in the args array. when you know the exact id of requested post you don’t need to use it like that. you can use this instead: get_post($id); And then … Read more

404 Template customization | Want 10 recent Post on the 404.php error page apart from the error Notice

The Loop just outputs what is contained in the Main Query, it doesn’t fetch any posts on its own. The Main Query is empty on a 404, so there’s nothing for The Loop to output. If you want additional content, you have to query for it yourself: $query = new WP_Query( array(‘posts_per_page’ => 10) ); … Read more

Random posts from a pool of posts

Quick & simple: You could simply use post__in in your query with the post IDs of those in your pool, though it might be less easy to maintain when you add and remove posts. Or you could use a meta field and change your query to include it, see the WP_Query documentation. Then either set … Read more
