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” 字段的值？

另外我想按“数据（电话）”进行数据排序。可能吗？

Answer 1

下面的代码将这个字符串转换成数组，并打印“数据”字段值...

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

Answer 2

默认情况下$wpdb->get_results()返回对象的数组，所以你可能想要这个：

foreach ($subs_results as $sub) { 
    echo $sub->data; 
}

注意，它会在wp_ninja_forms_subs表打印此字段的值每个记录。
