How to execute add_action() function from custom plugin to Crontrol plugin or do_action()?

I didn’t call the class yet, this code is now working class Scheduler { public $setup; public static $instance; public function __construct() { self::$instance =& $this; add_action(‘scheduler’, [$this, ‘etf_scheduler_func’]); } public function etf_scheduler_func() { $this->setup = new Setup(); $this->setup->set_table(); } public static function &get_instance() { if ( ! isset( self::$instance ) ) self::$instance = new … Read more

Custom post type functions.php if statement on action

you need a global $post; within that function before trying to access the contents of $post.

I add some js files from a plugin to a specific location

you have a $ undefined js error on line 191. wp_enqueue_script has a dependencies parameter, I think you need to pass the jquery-ui handle as a dependency with your accordion script so it loads first.

An action that runs after each post in the loop on index/archive page?

I am not aware of a dedicated action, but you could prevent double processing with an internal cache in your function. Pseudo code: function content_filter( $content ) { static $cache = array(); $id = get_the_ID(); if ( in_array( $id, $cache ) ) { return $content; // we did this already } $cache[] = $id; return … Read more

Create WordPress taxonomies based on theme settings

Yes. Post types and taxonomies are (should be) registered on the init hook. You are able to use get_option inside that hook to retrieve your theme’s settings and register your post type/taxonomy with args based on those settings. (By the way post types and taxonomies are really plug-in territory… 🙂 )

WordPress Plugin Receive a Link

You could, feasibly, do it with a custom field, ignoring ajax. You could store the ratings of each one in an array in the field. The star rating would be generated something like this: //note this is untested and provided as a guide not gospel $ratings = get_post_meta($post_ID,’star_ratings’); $total = 0; foreach($ratings as $rating) { … Read more

OOP Plugin: Where should I place the action hooks in the class?

Since you are using OOP, you probably want to architecture your plugin more efficiently. This is fine, but you’ll be the one to structure your classes and build them. So what if you put it in the __construct() function? That’s fine, as long as you initiate a new instance of the class. Putting it in … Read more

Create action running on trashed_post hook to modify post_meta value

wp_trash_post and trashed_post – from source: function wp_trash_post($post_id = 0) { if ( !EMPTY_TRASH_DAYS ) return wp_delete_post($post_id, true); if ( !$post = wp_get_single_post($post_id, ARRAY_A) ) return $post; if ( $post[‘post_status’] == ‘trash’ ) return false; do_action(‘wp_trash_post’, $post_id); add_post_meta($post_id,’_wp_trash_meta_status’, $post[‘post_status’]); add_post_meta($post_id,’_wp_trash_meta_time’, time()); $post[‘post_status’] = ‘trash’; wp_insert_post($post); wp_trash_post_comments($post_id); do_action(‘trashed_post’, $post_id); return $post; }

Redirect back to origin page after using get_delete_post_link()

Theres a filter you can hook on to. apply_filters( ‘get_delete_post_link’, wp_nonce_url( $delete_link, “$action-{$post->post_type}_{$post->ID}” ), $post->ID, $force_delete ); Check the raw function here: http://core.trac.wordpress.org/browser/tags/3.4.1/wp-includes/link-template.php#L954 Can’t advise much else without seeing your code. Edit: its nasty buy you can do add_filter( ‘get_delete_post_link’, ‘some_function’, 20 ); function some_function() { wp_redirect( home_url(“https://wordpress.stackexchange.com/”) ); exit; }

Plugin that generates a page of post content

I still don’t exactly get it. I would advise you to take it one step at a time first. Your function takes in a post_id, so that is an existing post. If you then get that post’s title and then you call get_page_by_title, obviously that is going return you the same than get_post already did. … Read more
