One approach is to modify the exclusion prefix through the wp_query_search_exclusion_prefix filter that’s supported in WP 4.7+. See ticket #38099. Here’s an example how we can change it from – to e.g. !: add_filter( ‘wp_query_search_exclusion_prefix’, function( $prefix ) { return ‘!’; // adjust to your needs (default is -) } ); where we would use … Read more
Well, get_posts() actually instantiates a new WP_Query object, so if you’re comfortable using WP_Query directly, don’t even bother with get_posts(); get_posts will only return the results from the database, whereas WP_Query gives you the whole functionality of the class.
As you haven’t stated what you are trying to achieve and have just mentioned you need to fetch associated data. You have two options to query your custom table: You need to do a custom query separately using the post id from the post object while iterating over the posts. Modify the joins of main … Read more
Yes but not in a single query, e.g.: if(is_multisite()){ global $wpdb; $blogs = $wpdb->get_results($wpdb->prepare(“SELECT * FROM $wpdb->blogs WHERE spam = ‘0’ AND deleted = ‘0’ and archived = ‘0’ and public=”1″”)); if(!empty($blogs)){ ?><?php foreach($blogs as $blog){ switch_to_blog($blog->blog_id); $details = get_blog_details($blog->blog_id); $q = new WP_query(); if($q->have_posts()){ while($q->have_posts()){ $q->the_post(); // do things break; } } wp_reset_query(); restore_current_blog(); … Read more
Sorry, doesn’t work that way. The “simple” meta parameters are converted into part of the meta_query as a whole. So it’s not a separate thing, and your OR relation applies to it as well. Your query thus is not possible with the normal query system, because you want to mix ANDs with ORs (you want … Read more
You could look at modifying the WP_Query with a SQL command to group them, but that’s a bit beyond my current MySQL, however, I’ve always done it by running a foreach on the taxonomy itself with this http://codex.wordpress.org/Function_Reference/get_categories Here’s some sample code: <?php global $post; $current = get_the_ID($post->ID); $cargs = array( ‘child_of’ => 0, ‘orderby’ … Read more
No. Parameters given to the WP_Query object only need to be escaped for the database query – this is handled by WordPress.
In my experience using ‘posts_*’ filters (‘posts_request’, ‘posts_where’…) in combination with str_replace / preg_replace is unreliable and unflexible: Unreliable because if another filter modify uses one of that filters, in better case one gets unexpected results, in worst cases one gets SQL errors. Unflexible because changing an argument, e.g. ‘include_children’ for categories, or reuse the … Read more
I pretty sure this filter lets you add an array of variables. I’ve not tested this: function add_custom_query_vars( $vars ){ $vars[] = “variable1”; $vars[] = “variable2”; $vars[] = “variable3”; //… etc return $vars; } add_filter( ‘query_vars’, ‘add_custom_query_vars’ ); Or another way of doing it would be to do this: function add_custom_query_vars( $vars ){ array_push($vars, “variable1”, … Read more
Here are three possibilities, based on the /wp-admin/admin.php file: Method #1 There are the global $pagenow and $typenow available: global $pagenow, $typenow; if( ‘my_venue’ === $typenow && ‘edit.php’ === $pagenow ) { // … } Method #2 Then there’s the current screen, also set in the admin.php file with set_current_screen(); $screen = get_current_screen(); if( is_a( … Read more
