我试图根据post_type条件将$ message_array中的随机消息添​​加到此WP表中。没有任何事情发生。

Answer 1

使用wpdb-＆gt;更新..

while ($count <= 18614) {
            $random_message = $message_array[mt_rand(0, count($message_array) - 1)];
            $cell_type_pre = $conn->get_results("SELECT `post_type` FROM `wp_posts` WHERE `id` = " . $count);
            $cell_type = $cell_type_pre[0]->{"post_type"};
            if ($cell_type == "post") {
                $conn->update('wp_posts', array('post_excerpt' => $random_message),array( 'ID' => $count, 'post_excerpt' => ''));
            }
            if ($cell_type == "attachment") {
                $conn->update('wp_posts', array('post_content' => $random_message),array( 'ID' => $count, 'post_content' => ''));
            }
            $count++;
        }
