Yes, I already knew the cause of what you’re experiencing: The $page and $pages global variable have not been set up and a call to get_the_content or get_the_excerpt would return that error: count(pages) That said, pages global variable is set to null, calling count(pages) triggers that error because a null value cannot be counted. To … Read more
Depends on whether or not you need to check against WordPress’ user authentication. If you need to know whether they’re a logged in user, hook onto ‘init’. Otherwise, the sooner the better. If it’s something that should fire on every page load, and only checks for existence of the cookie and doesn’t need to tap … Read more
You can filter the $phpmailer object. Something like this should do the trick (not tested): add_action( ‘phpmailer_init’, ‘wpse_52555_msg_id’ ); function wpse_52555_msg_id( &$phpmailer ) { $msg_id = get_post_meta( get_the_ID(), ‘messageID’, TRUE ); ” !== $msg_id and $phpmailer->MessageID = $msg_id . ‘@test.com’; }
Include this small plugin, activate and test. A tested version in 3.6-alpha, works only on click on a thumbnail. <?php /** * Plugin Name: Remove Attachment Link-To and set to value ‘none’ */ add_action( ‘admin_footer-post-new.php’, ‘wpse_76214_script’ ); add_action( ‘admin_footer-post.php’, ‘wpse_76214_script’ ); function wpse_76214_script() { ?> <script type=”text/javascript”> jQuery(document).ready( function($) { $( ‘li.attachment’ ).live( ‘click’, function( … Read more
The action init happens too early to know if the current page should display a page. You have to wait at least until template_redirect. But if you want to print something to the page, use the_content.
This is what normal query run by wp_get_associated_nav_menu_items() looks like: SELECT wp_posts.* FROM wp_posts INNER JOIN wp_postmeta ON ( wp_posts.id = wp_postmeta.post_id ) WHERE 1 = 1 AND wp_posts.post_type=”nav_menu_item” AND (( wp_posts.post_status <> ‘trash’ AND wp_posts.post_status <> ‘auto-draft’ )) AND (( wp_postmeta.meta_key = ‘_menu_item_object_id’ AND Cast(wp_postmeta.meta_value AS CHAR) = ‘3111’ )) GROUP BY wp_posts.id ORDER … Read more
WordPress provides a filter called wpmu_new_blog and passes the parameter $blog_id (the ID of the new blog) and $user_id (the user, that just created that new blog) (and some more) to it. You can hook into this action to create the new pages and edit the options: <?php /** * Plugin Name: Default Site Structure … Read more
I finally got it. First mistake was to process the same function twice. I’ve called it once after the function and one more time in ajax action. So when using the ajax call, the function got executed twice. In the example from the OP, this is not a problem at all, because it is simplified … Read more
I’m not sure why you’re getting a 500 error. Likely because you’re trying to use a function before it’s been defined. But I think you’re going about the problem the wrong way. Genesis does provide a filter before returning the search form. Why not just add a filter to the genesis_search_form hook? You can add … Read more
You can change the priority of actions and filters, it’s the third argument of add_filter (and add_action) and it defaults to 10. So change it to a high number and have your filter fire way after the shortcodes and other stuff are inserted. <?php add_filter(‘the_content’, ‘disable_autocomplete’, 99); function disable_autocomplete( $content ) { return str_replace(‘<form’, ‘<form … Read more
