Question

我有以下代码：

function process_bulk_action() {
        if (isset($_GET['locations'])) {
                $location_ids = ( is_array( $_GET['locations'] ) ) ? $_GET['locations'] : array( $_GET['locations'] );
                global $wpdb;

                switch ( $this->current_action() ) {
                    case 'edit':
                         bulk_edit($location_ids);
                    break;
                    case 'delete':
                        bulk_delete($locations_ids);
                    break;
                    default:break;
                }
        }
    }

    function bulk_delete($ids) {
        foreach ( $ids as $id ) {
            $id = absint( $id );
            $sql = "DELETE FROM wp_nc_location WHERE location_id = $id";
            $delete = $wpdb->query( $sql );
        }
    }

    function bulk_edit($ids) {
        foreach ( $ids as $id ) {
            $id = absint( $id );
            $sql = "SELECT name FROM wp_nc_location WHERE location_id = $id";
            $select = $wpdb->query( $sql );
            echo 'select: '. $select. ',';
            print_r($select);
        }
    }

但是当我尝试从上面的switch语句中调用bulk_edit或bulk_delete时，我收到以下错误消息：

Fatal error: Call to undefined function bulk_delete

我意识到我的范围有问题，但我不确定在哪里放置函数bulk_edit或bulk_delete ......

我猜你在各个地方使用$this->这些函数属于一个类吗？在这种情况下，您必须调用函数，如... $this->bulk_delete(..arguments..);

Php范围问题（引用另一个函数内部的函数）
