Question

我在查询BuddyPress表的WordPress安装的外部文件上有以下查询。我没有收到任何错误但结果显示？

$the_pro = "". implode(", ", $user) ."";

    $query ="SELECT 
        (SELECT value  FROM wp_bp_xprofile_data WHERE 'user_id' IN (" . $the_pro . ") AND field_id = '2') as 'prof',
        (SELECT value  FROM wp_bp_xprofile_data WHERE 'user_id' IN (" . $the_pro . ") AND field_id = '3') as 'address',
        (SELECT value FROM wp_bp_xprofile_data WHERE 'user_id' IN (" . $the_pro . ") AND field_id = '4') AS 'city',
        (SELECT value FROM wp_bp_xprofile_data WHERE 'user_id' IN (" . $the_pro . ") AND field_id = '5') AS 'state',
        (SELECT value FROM wp_bp_xprofile_data WHERE 'user_id' IN (" . $the_pro . ") AND field_id = '6') AS 'zip',
        (SELECT value FROM wp_bp_xprofile_data WHERE 'user_id' IN (" . $the_pro . ") AND field_id = '7') AS 'link'
        ";
     $results = mysql_query($query);
 while($row = mysql_fetch_array($results)) { 

?>

        <div style="padding-bottom:4px; border-bottom:#CCC 1px solid;" >
        <div class="prof"><a href="#" onClick="myClick(0);"><?php echo $row['prof']; ?></a></div>
        <div class="address"><span style="margin-bottom:3px;"><?php echo $row['address']; ?></div>
        <div class="local"><?php echo $row['city']; ?>, <?php echo $row['state']; ?> &nbsp;<?php echo $row['zip']; ?></div>
        </div>
        <?php 
  }?>

请尝试添加： if（！$ result）{ 死（＆＃39;无效的查询：＆＃39; .mysql_error（））; } 所以你知道是否有错误或者它确实返回了空结果。

MySQL Query不显示结果
