If you use WP_Query you can set the orderby to modified and then the order to DESC and you’ll be good to go. If it’s not a custom query, you can just use the set() method on the default $wp_query global to do the same. Since get_posts() is just a wrapper for WP_Query, you can … Read more
This “not exists” functionality isn’t possible using a regular meta query. It’s being worked on, but it looks like it’s been shuffled to a future release (see this trac ticket for more insight). In the meantime, you have to run a custom SQL statement using $wpdb, as in DeadMedic’s answer that Milo linked to in … Read more
From the WordPress Codex, I believe you want the function paginate_links http://codex.wordpress.org/Function_Reference/paginate_links Example: <?php echo paginate_links( $args ) ?>
use wp_reset_query after your loop to restore the global post data for the main loop.
When you do the following in your code $posttags = get_the_tags($item->term_id);, $item is referring to a post object, not a term object. Therefore, term_id is an invalid property. This should be throwing a PHP notice. While not certain, I think what you are intending to do is: $posttags = get_the_tags($item->ID); since get_the_tags takes a post … Read more
First of all. The question is a little misleading. What you actually want is “post id(s) for current user”. Here we go: // Global variable for current user ID // More information: http://codex.wordpress.org/Function_Reference/get_currentuserinfo $user_ID; // You need to create a new WP query object // More info: http://codex.wordpress.org/Class_Reference/WP_Query $my_query = new WP_Query( array( ‘post_type’ => … Read more
You can’t, at least not efficiently. You best bet is to use the LIKE statement, but it would fail for searches like “title”, “link”, “mp3” 🙂 I suggest you build your own serialization method. For example, store the tracklist as a string like this: Track1 title Track2 title Notice the new line character (\n). Use … Read more
If it’s not timing out, you’re likely running out of memory.
You can get information on the currently logged in user using the get_currentuserinfo() function. For example: <?php global $current_user; get_currentuserinfo(); $username = $current_user->user_login; $user_id = $current_user->ID; ?> You can then use $username or $user_id in your custom loop. <?php // assign the variable as current category $category = $user_id; // concatenate the query $args=”cat=” . … Read more
There is nothing wrong with your query, this is normal for WordPress. What is typically more important is the “total query time”. A well written theme with over 100 queries will often ring in under 20 milliseconds, that is 4-20 times faster than the blink of an eye. With a caching plugin you can can … Read more
