查询

$subs_results = $wpdb->get_results("SELECT * FROM wp_ninja_forms_subs WHERE form_id = 1 ORDER BY date_updated DESC")

如何打印“数据”字段值？

我还想按“数据(电话)”对数据进行排序。这可能吗？

Answer 1

以下代码会将此字符串转换为数组并打印“data”字段值...

foreach ($subs_results as $sub)
{
    $data = unserialize($sub->data);
    echo "<pre>";
    print_r($data);
    echo "</pre>";
}
