Display current ranking of post as a number in post title

Could make it work already 🙂 class MY_Post_Numbers { private $count = 0; private $posts = array(); public function display_count() { $this->init(); // prevent unnecessary queries $id = get_the_ID(); echo sprintf( ‘<div class=”post-counter”>Post number<span class=”num”>%s</span><span class=”slash”>/</span><span class=”total”>%s</span></div>’, $this->posts[$id], $this->count ); } private function init() { if ( $this->count ) return; global $wpdb; $posts = $wpdb->get_col( … Read more

Override orderby to create list of users by custom meta_value

Try this code, but replace METAKEY to the key-name of your metadata. <?php function cmp( $a, $b ) { if( $a->METAKEY == $b->METAKEY ){ return 0 ; } return ($a->METAKEY < $b->METAKEY ) ? -1 : 1; } ?> <ul> <?php $args = array( ‘role’ => ‘author’ , ‘meta_key’ => ‘METAKEY’, ‘number’ => 5, ); … Read more

Show array of meta_value in Edit Post Coloum

The error was here: (Thank you @Rarst) if ($column_name == ‘custom_checkbox_group_sesso’) { $sesso_occupanti = get_post_meta($post_ID, “custom_checkbox_group_sesso”, true); //check that we have a custom field if ($sesso_occupanti != “”) { // Separate our comma separated list into an array $sesso_occupanti = explode(“,”, $sesso_occupanti); //loop through our new array foreach ($sesso_occupanti as $sesso) { echo $sesso ; … Read more

How to show or hide a post based on meta_value selection?

Use the pre_get_posts action to alter the main query with meta_query arguments to only select posts with active current_status. This example would work for your main posts page. See Conditional Tags for how to determine when other types of queries are run. function wpa_current_status( $query ) { if ( $query->is_home() && $query->is_main_query() ) { $meta_query … Read more

updating one custom meta field only

It sounds like you are trying to directly save the altered information to the serialized value in the database. You can’t do that. You have to extract the current meta data for that key so that you have and array or object, update that array or object, and then save the whole thing back to … Read more

Sort column on meta key and meta value

Have you tried changing your orderby value to meta_value, rather than meta_value_num in your status_column_orderby function? This has always worked for me in the past. I’m assuming we are dealing with words, not numbers, since you said “alphabetically” in your question. meta_value is for letters/characters, with meta_value_num reserved for… you guessed it… numbers.

How can I use ‘orderby’ => ‘meta_value_num’ to order by the numerical value even if the value starts with a word?

If you look at the 50+ similar questions on Stack Overflow you’ll see that you can only do so with considerable difficulty, and you won’t have a very efficient query once you get it working. MySQL just isn’t built to sort that way, and honestly the sort pattern you want is really very peculiar anyway. … Read more

Nested relations among subset of meta queries are possible on WP 4.1 that is planned to be releaded next coming December 10, 2014. See trac ticket. So wait a few days or use the beta version.

Show posts of an advanced search form

If I am reading your question right, you need AND not OR for the meta query relation ‘relation’ => ‘AND’, I don’t see where you’ve set the $product_* values either. You should be using $_GET[‘product_color’] (etc), but you need to sanitize that user supplied data. I would use a “whitelist” technique if it were me: … Read more

query_posts with meta_value

Per comments, just use pre_get_posts filter (no query_posts()) very much as you have it with a few adjustments, eg test for $query->is_category( ‘news’ ) so that it only runs on news queries, and set the default to “2014” rather than bailing on no $_GET, eg function wpse129223_custom_meta_query( $query ) { // If not on the … Read more
