我正在尝试更新数据库中的特定行

更新过程正常，但其中一个字段没有更新{它确实更新了，但当我检查数据库时，它显示为0，我无法找出代码的问题所在}

任何帮助都会很好

该问题是它的成员id

成员在数据库中标识其int数据类型

更新代码

  if (isset($_POST['submitted']))
{
$plan_id=$_POST['plan_id'];
$member_id=$_POST['member_id'];
$trainer_id=$_POST['trainer_id'];
$exercise_id=$_POST['exercise_id'];

$weight=$_POST['weight'];
$comment=$_POST['comment'];

$_SESSION['edit-ex']=$message2;
    }// to check if the query run then show this message

    {
    die(mysql_error());
    }
}

if（isset（$\u POST['submitted']））
{

如果（$结果）

其他的

无标题文件
尝试在字段中添加单引号（“”）
   $query = "UPDATE gym_plan SET ";
   $query.= "'exercise_id' = {$exercise_id}, ";
   $query.= "'exercise_set' = '{$Set}', ";
   $query.= "'trainer_id' = {$trainer_id}, ";
   $query.= "'member_id' = {$member_id}, ";
   $query.= "'comment' = '{$comment}', ";
   $query.= "'member_id' = '{$memberadd}', ";
   $query.= "'weight' = '{$weight}' ";

或者查看此
您的问题在这一行：
$query.= "member_id = '{$memberadd}', ";

$query.= "member_id = {$member_id}, ";

$query.= "member_id = '{$memberadd}', ";

您正在同一查询中将member_id更新为2个值，第二个值$memberadd
未设置，因此为0

在这方面很好：
$query.= "member_id = '{$memberadd}', ";

$query.= "member_id = {$member_id}, ";

$query.= "member_id = '{$memberadd}', ";

这一行不好：
$query.= "member_id = '{$memberadd}', ";

$query.= "member_id = {$member_id}, ";

$query.= "member_id = '{$memberadd}', ";

旁注：您应该停止使用mysql_*函数，因为它们已被弃用。签出或
您不能发布比此更少的代码吗？你不能再缩小范围了吗？
