When WordPress activates a plugin, it calls the activate_plugin() function. This function activates the plugin in a sandbox and redirects somewhere else on success. It’s been used by a few authors to programmatically activate plugin dependencies. There’s another function, deactivate_plugins(), that does a similar thing in reverse … it’s actually how WordPress deactivates plug-ins when … Read more
This is how I did it in some web apps: function run_activate_plugin( $plugin ) { $current = get_option( ‘active_plugins’ ); $plugin = plugin_basename( trim( $plugin ) ); if ( !in_array( $plugin, $current ) ) { $current[] = $plugin; sort( $current ); do_action( ‘activate_plugin’, trim( $plugin ) ); update_option( ‘active_plugins’, $current ); do_action( ‘activate_’ . trim( … Read more
That’s because the file in which is_plugin_active() is defined – wp-admin/includes/plugin.php – is only loaded in the admin, after your plugin is loaded. Thus, you can only call it after ‘admin_init’ has fired: function check_some_other_plugin() { if ( is_plugin_active(‘some-plugin.php’) ) { … } } add_action( ‘admin_init’, ‘check_some_other_plugin’ );
When your going through your loop add this: global $post; $post = get_post( $ID, OBJECT ); setup_postdata( $post ); //Do something wp_reset_postdata();
The wp_insert_post_data filter can do that: add_filter( ‘wp_insert_post_data’ , ‘filter_post_data’ , ’99’, 2 ); function filter_post_data( $data , $postarr ) { // Change post title $data[‘post_title’] .= ‘_suffix’; return $data; }
you can try to use the script_loader_src filter hook e.g: add_filter(‘script_loader_src’,’add_id_to_script’,10,2); function add_id_to_script($src, $handle){ if ($handle != ‘dropbox.js’) return $src; return $src.”‘ id=’dropboxjs’ data-app-key=’MY_APP_KEY”; } Update i just figured it out myself that the src is escaped by esc_url, so looking a bit more i found the clean_url filter which you can use to return … Read more
Products in WooCommerce are a custom post type, so this should work: $url = get_permalink( $product_id ); You can treat that $product_id as a postID (that’s what it is), so you can use it with other normal WP functions, like: echo ‘<a href=”‘.get_permalink($product_id).'”>’.get_the_title($product_id).'</a>’;
A Custom Fields UI I think really custom fields with custom UI is really a big requirements for a lot of people. I mean, compulsory, repeating, grouped, multiple images, etc. There is a bunch of plugins trying to provide the functionality, but they are all add-ons and have to play catch up to new WP … Read more
Answer to the First question: In wp-settings.php, WordPress first checks for any must-use plugins (plugins in the optional mu-plugins folder) and loads those. Then, if you’re running a multisite installation, it checks for plugins that are network-activated and loads those. Then it checks for all other active plugins by looking at the active_plugins entry of … Read more
