How to prevent a post from being deleted?
Don’t let the action die, just do a redirect (to wherever you’d like): function wpse_92155_before_delete_post() { wp_redirect(admin_url(‘edit.php’)); exit(); } // function wpse_92155_before_delete_post add_action(‘before_delete_post’, ‘wpse_92155_before_delete_post’, 1);
Uncaught Error: Call to undefined function wp_generate_attachment_metadata() @ wp-cron
Some of what is usually admin side functionality is not included as part of the “main” wordpress bootstrap, files containing uploaded file manipulation functions are one of them and you need to explicitly include them by adding include_once( ABSPATH . ‘wp-admin/includes/image.php’ ); into your call_import function.

And “wpseo_meta” was the ID of the metabox. So the same code can be used on any meta … Read more

Unable to check if plugin is active
Try to check class_exists: <?php if( class_exists(‘acf’) ) { echo “hi”; } ?>
is_plugin_active() returning false on active plugin
is_plugin_active() expects just the base name of the plugin as parameter: So use: is_plugin_active( ‘woocommerce/woocommerce.php’ ); The function will use the option ‘active_plugins’ which is a list of plugins paths relative to the plugin directory already. On a multi-site installation it will search in get_site_option( ‘active_sitewide_plugins’) too. As an implementation note: Avoid these checks. Some … Read more
