代码改错function all_view global wpdb; $count = 0; $views=$wpdb-get_resultsSELECT FROM $wpdb-postmeta WHERE meta_key=views; foreach$views as $key=$value $meta_value=$value-meta_va

function all_view() { global $wpdb; // Corrected wpdb to $wpdb $count = 0; $views = $wpdb->get_results("SELECT * FROM $wpdb->postmeta WHERE meta_key='views'"); foreach($views as $key => $value) { $meta_value = $value->meta_value; if($meta_value != '') { // Removed unnecessary space in comparison $count += (int)$meta_value; // Added $ sign before meta_value } } return $count; }
