intval() behaves sometimes a little bit counter-intuitive when then value has leading zeros or when it is a mathematic expression. The result should always be safe, but is not always what you might expect. A simple example: intval( ‘9223372036854775808’ ); will never return this value, because even 64 bit system cannot handle such a large … Read more
You can use filter posts_clauses For example: add_filter( ‘posts_clauses’, ‘post_query_order’, 20, 1 ); function post_query_order( $pieces ) { global $wpdb; $pieces[‘orderby’] = $wpdb->prefix.’posts.post_type ASC’; return $pieces; }
To be able to use a variable that is essentially being created within the shortcode function, you’ll need to store it somewhere and then retrieve the value. WordPress does use global variables internally to store and carry across values, but I wouldn’t advise you do the same though. Read about the options API here. Pretty … Read more
With some trial and error and help from @vancoder , the problem had to do with intval. The only section needing to be modified was the posts_where function. Had to remove the following line: $propertytype_value_number = intval( $_GET[‘propertytype_value_restrict_articles’] ); And change: AND meta_value=$beds_value_number )”; to AND meta_value=””.$_GET[“propertytype_value_restrict_articles’].”‘ )”; I had to also modify the original … Read more
function disable_editor_for_old_posts_wpse_101106($post) { if (strtotime(‘-2 months’) > strtotime($post->post_date)) { remove_post_type_support(‘post’,’editor’); } } add_action(‘add_meta_boxes_post’, ‘disable_editor_for_old_posts_wpse_101106′); I couldn’t find a great hook for this but add_post_meta_boxes_* is early enough, and it passes the $post object to the callback. Basically the filter checks the post on the post edit screen and removes post type support based on the … Read more
The allowed tags are stored in $allowedposttags (located in /wp-includes/kses.php) as an array. For each element it looks something like this: $allowedposttags = array( ‘div’ => array( ‘align’ => true, ‘dir’ => true, ‘lang’ => true, ‘xml:lang’ => true, ) ); You can remove a single element of an array via unset unset($allowedposttags[‘div’]);
add_filter(‘some_base_handle’.sanitize_title($string), …) What he’s doing here is a variable filter handle, and while “sanitize_title” might not be exactly the correct function to use here, it really depends on what the possible values of $string are and what the source of that $string is. Variable filter names can be handy if you have a lot of … Read more
The way you do it is fine. Also have a look at how Tom McFarlins WordPress Plugin Boilerplate does it: if ( is_admin() && ( ! defined( ‘DOING_AJAX’ ) || ! DOING_AJAX ) ) { require_once( plugin_dir_path( __FILE__ ) . ‘admin/class-plugin-name-admin.php’ ); add_action( ‘plugins_loaded’, array( ‘Plugin_Name_Admin’, ‘get_instance’ ) ); } Source
If anyone should be faced with this problem, check if you have defined a callback function to set the user_login on pre_user_login. This filter is applied inside the wp_insert_user()-function and produced a same username again. Therefore the nicename was changed by adding a “-2”. So, my problem was that I reset the user_logins again and … Read more
This should work, regardless how many tags you have in the post, and regardless which have whatever attributes. My guesses are either the logic in your handler is slightly off, or a 3rd party (i.e. plugin) is hijacking the default shortcode handler behaviour. To test, remove your code and try the following – it should … Read more
