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 }
Here are two simple ways to do this: One is to use the the_content-filter to update the post “hotness”, or you can schedule an event that will run daily and update the “hotness” once a day. 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
There is the action hook user_register that is called immediately after a user is added to the database. The user id is passed to the hook as an argument. You can use wp_insert_post to insert a new post in that action. You just need to get the relevant info from the user and add it … Read more
The post by itself is only data, it cannot perform such action as expiring itself. So you need some form of external control to act on it. You can use WP Cron (see wp_schedule_event() and related) to run periodic task that will query for posts by your custom field and perform wanted action on them … Read more
A simple user meta row can handle that for you (the second issue), you can store the post id and the vote (up/down) in an array and that is just the same as post meta ex /** * update user vote per post * @param int $user_id * @param int $post_id * @param mixed $vote … Read more
it seems that you’re using that plugin in a wrong way. It’s not necessary hook to save_post because the plugin do it for you. Simply register your meta box and your fields. To retrieve the values check this
