Add an array and choose one for the value. add_action(‘draft_post’, ‘add_custom_field’); function add_custom_field($post_ID) { global $wpdb; if(!wp_is_post_revision($post_ID)) { $colors = array(‘white’, ‘green’, ‘blue’); add_post_meta($post_ID, ‘random_color’, $colors[array_rand($colors, 1)], true); } }
Try this: add_filter(‘posts_where’, ‘unquote_numeric_meta_value’, 10, 2); function unquote_numeric_meta_value($where, $args) { $value = isset($args->query_vars[‘meta_value’]) ? $args->query_vars[‘meta_value’] : false; if(is_numeric($value)) $where = str_replace(“‘{$value}'”, $value, $where); return $where; }
// function to show a banner using query of banner post type function show_banner( $att ) { // Set default $att values if none is provided // $att is an array so access the shortcode value via $att[‘thumbnail_id’] // in the [banner thumbnail_id=”12″] shortcode $atts = shortcode_atts( array( ‘thumbnail_id’ => ”, ), $atts, ‘banner’ ); … Read more
This question is off-topic because your is a simple PHP error, not related to WordPress. You are trying to check if a variable is empty using: if ( $meta != $empty ) { but this is not the right way, in fact this code compare the target variable $meta with another variable $empty that is … Read more
This is the solution, according to the asker. He used the get() method of the WP_Query class to retrieve an array of values (colors), each stored with the meta key color. Because [color] => ‘Yellow’ may appear in the array more than once, he then filtered the array through the PHP function, array_unique() which will … Read more
Well, you can’t sort by field that isn’t there. You can modify query conditionally only in those categories which have that field and let default query work in rest. It would be something like: if( is_category(‘abs’) ) query_posts( array_merge( array(‘orderby’ => ‘meta_value’, ‘meta_key’ => ‘field_order’, ‘order’ => ‘Desc’ ), $wp_query->query ) );
If every meta value has the key f_name $meta = get_post_meta($post->ID, “company_wp_box_g”, true); echo $meta[‘fname’]; If you’re not sure of the contents & want to search for the first one available $name = false; $meta = get_post_meta($post->ID, “company_wp_box_g”, false); foreach($meta as $array) { if(isset($array[‘f_name’])) { $name = $array[‘f_name’]; break; } } echo $name;
Using save post action I check state: <?php add_action(‘save_post’ ,’my_save_postdata’); function my_save_postdata ( $post_id ) { if ( defined(‘DOING_AUTOSAVE’) && DOING_AUTOSAVE ) { return $post_id; } // logic }

First approach: the_content-filter Turn you code in to a “callable” function: function update_hotness( $post_id, $echo = false ) { … Read more
If I’m understanding correctly, you want to use your own select form to update a post’s published status instead of the publish/unpublish buttons? Something like this would work for that: function save_my_data($post_id){ if($_POST[‘publish’] == ‘yes’ && get_post_status($post_id) != ‘publish’){ //whatever your post variable is remove_action(‘save_post’, ‘save_my_data’); //if you don’t unhook the function you’ll have an … Read more
