if you want to use ajax in wordpress you must have to follow these step: 1) first make your js file like main.js. 2) localize it in functions.php with wp_localize_script(). wp_enqueue_script( ‘main.js’, get_template_directory_uri().’/js/main.js’, array( ‘jquery’ ) ); wp_localize_script( ‘main.js’, ‘ajax_object’, array(‘ajax_url’ => admin_url(‘admin-ajax.php’)) ); 3) make your javascript or jquery code to run your query … Read more
I found some hints here: Can i merge 2 new WP_Query($variable) ‘s? So i created two separate queries and merged them into a new array: $wp_query = new WP_Query(); $wp_query->posts = array_merge( $query1->posts, $query2->posts ); foreach($wp_query->posts as $post) : setup_postdata( $post ); And then the usual stuff.
Does calling the $query->query($args) method do anything different? $query = new WP_Query( $args ); is simply a shortcut to the “instantiate class first, query later” version like $query = new WP_Query; $posts = $query->query( $args );. You can see it from the class constructor source here: public function __construct( $query = ” ) { if … Read more
My recommendation would be to use query_posts() to modify your query such that orderby=title and order=ASC … this will return the same results as your first query, but with the posts ordered alphabetically by title.
Just a quick update that a new method is_main_query() has been introduced in WP 3.3. Example: add_action( ‘pre_get_posts’, ‘foo_modify_query_exclude_category’ ); function foo_modify_query_exclude_category( $query ) { if ( $query->is_main_query() && ! $query->get( ‘cat’ ) ) $query->set( ‘cat’, ‘-5’ ); } Resources: WPDevel: New API in 3.3: is_main_query() Codex reference: is_main_query() Related Trac Ticket #18677
You’re getting all the posts because you set ‘meta_key’ => ‘event_date’. This is equivalent to adding another subquery into ‘meta_query’ that says “get me all posts which have an event_date custom field, with any value OR that have even_date to $today etc.”. PS: There are many event plugins out there that have already figured all … Read more
It’s better to use get_children than get_posts. Here is a quick example that will work. This is in the form of a function that is defined in your plugin or in functions.php then use the function as a template tag. /** * Gets all images attached to a post * @return string */ function wpse_get_images() … Read more
No, there is no way to do this with default WP Core. @heathenJesus talks about meta data not taxonomies. See http://scribu.net/wordpress/sortable-taxonomy-columns.html for a proper solution. And a more thorough explanation of why this is not something built into Core: Using wp_query is it possible to orderby taxonomy?
The is the the_posts filter, which sounds like what you want. function filter_the_posts($posts) { var_dump($posts); } add_filter(‘the_posts’,’filter_the_posts’);
The issue is that WordPress are getting all posts that has a ‘startDate’ meta key, no matter the meta value. You can understand that form this part of the request: … AND ( wp_postmeta.meta_key = ‘startDate’ OR ( mt1.meta_key = ‘startDate’ AND CAST(mt1.meta_value AS CHAR) >= ‘20140305’ ) OR ( mt2.meta_key = ‘endDate’ AND CAST(mt2.meta_value … Read more
