As documented: setup_postdata() does not assign the global $post variable so it’s important that you do this yourself. Failure to do so will cause problems with any hooks that use any of the above globals in conjunction with the $post global, as they will refer to separate entities. So you need to do this: global … Read more
The solution to that was pretty simple. I just replaced get_posts() with a simple new WP_query() : $query = new WP_query($args); I guess now you have a ready-to-implement function for pagination ^^
Your issue is not with storage, it is with retrieval. get_post_custom() is inconvenient and rarely used in practice. get_post_meta() is more common in practice. Note it has explicit argument to retrieve a single value, rather than array of values for a key (which WP can do too).
Every page has a “main query” which is run before the template is loaded. The results of the main query are how WordPress determines what template to load. The standard Loop operates on the data contained in the main query, this is why it seems to just magically “work” without you having to explicitly query … Read more
You can specify multiple categories within has_category like so: if ( has_category( array( ‘category_1’, ‘category_2’ ) ) { // do something } However, I am not sure if this acts as AND or OR, meaning does it require that ALL categories specified are matched, or one of the X supplied (category_1 OR category_2). In any … Read more
$args = array( ‘post_type’ => ‘post’, //Specifying the type of posts ‘cat’=> 1, //Selecting post category by ID to show ‘posts_per_page’ => 4, //No. of posts to show ‘paged’ => $paged //For pagination ); //You dont need to use query_posts( $args ); since you are using wp_query $query = new WP_Query( $args ); Use while … Read more
Call a external script: Your function look like this: <?php function modify_posts() { $number_posts = 10; $offset = 0; $success=”success”; while ( ‘success’ === $success ) { $url = add_query_arg( array( ‘num’ => $number_posts, ‘off’ => $offset, ‘abs’ => urlencode( ABSPATH ) ), plugins_url( ‘remote_get.php’, __FILE__ ) ); $response = wp_remote_get( $url ); if ( … Read more
Now try this, surely it will work query_posts(“cat=1, 2&showposts=5&post_type=item”); while(have_posts()) : the_post(); echo $title = get_the_title(); echo $content = get_the_content(); endwhile;
If you just want to return published posts, you can exclude the ‘post_status’ argument as by default it will just return published posts only. Having said that, the array works for me too though.
You can use add_image_size function to add new image size and can use wp_get_attachment_image to retrieve those custom size image.
