Question

有人可以帮我弄清楚为什么这不起作用吗？

我的更新功能不能处理我的PHP代码。我有一个断点，它列出了for循环末尾的所有信息，这是正确的信息。但是它每个ID打印约50次。此外，它不会更新SQL表。

我该如何解决这个问题？

段：

if ( isset( $_POST[ 'RemarketingRollCall' ] ) )
                            {

echo 'RollCall called ';
foreach($_POST['userid'] as $param1){
  foreach($_POST['name'] as $param2){
    foreach($_POST['job'] as $param3){
      foreach($_POST['monday'] as $param4){
        foreach($_POST['tuesday'] as $param5){
          foreach($_POST['wednesday'] as $param6){
            foreach($_POST['thursday'] as $param7){
              foreach($_POST['friday'] as $param8){

                $idnumber = mysqli_real_escape_string( $con, $param1 );
                $Name = mysqli_real_escape_string( $con, $param2 );
                $Job = mysqli_real_escape_string( $con, $param3 );
                $Monday = mysqli_real_escape_string( $con, $param4 );
                $Tuesday = mysqli_real_escape_string( $con, $param5 );
                $Wednesday = mysqli_real_escape_string( $con, $param6 );
                $Thursday = mysqli_real_escape_string( $con, $param7 );
                $Friday = mysqli_real_escape_string( $con, $param8 );

                echo "(". $idnumber . " " . $Name . " " . $Job . " " . $Monday . " " . $Tuesday . " " . $Wednesday . " " . $Thursday . " " . $Friday . ")";
                $sql = "UPDATE `Employee` SET `Job`='$Job', `Monday`='$Monday', `Tuesday`='$Tuesday', `Wednesday`='$Wednesday', `Thursday`='$Thursday', `Friday`='$Friday' WHERE `ID`=$idnumber";
                mysqli_query($con,$sql);
                if ( !mysqli_query( $con, $sql ) )
                  {
                    die( 'Error: ' . mysqli_error( $con ) );
                  }                 
              }
            }
          }
        }
      }
    }
  }
}
mysqli_close( $con );
?>
//putting a script here

这是输出：http://gyazo.com/3006df320d4857314ea486936f656ba3

这是我的表生成：

Answer 1

 $index = 0;
 foreach ($_POST as $key => $value){
   $idnumber = $_POST['userId'][$index];
   $Name = $_POST['name'][$index];
   $Job = $_POST['job'][$index];
   $Monday = $_POST['monday'][$index];
   $Tuesday = $_POST['tuesday'][$index];
   $Wednesday = $_POST['wednesday'][$index];
   $Thursday = $_POST['thursday'][$index];
   $Friday = $_POST['friday'][$index];
   $index++;
   // put your sql UPDATE here
}

您没有显示while {

的右括号

  </select></td>";
  }
  echo "<td name='week[]' contenteditable='false' align='center' width='11%'>" . $row['Week'] . "</td>";
  echo "</tr>";
  echo "</form>";

如果它在这里：

  </select></td>";
  }
  echo "<td name='week[]' contenteditable='false' align='center' width='11%'>" . $row['Week'] . "</td>";
  echo "</tr>";
  echo "</form>";
}  // is it here????????????

如果大括号是我认为的那个，你需要把它移到这里

  </select></td>";
  }

  echo "<td name='week[]' contenteditable='false' align='center' width='11%'>" . $row['Week'] . "</td>";
  echo "</tr>";
}  // <==========================
  echo "</form>";

然后移动：

while($row = mysqli_fetch_array($remarketingRoll)) {
  echo "<form id='RemarketingRollCall' method='POST'>";

要：

echo "<form id='RemarketingRollCall' method='POST'>";
while($row = mysqli_fetch_array($remarketingRoll)) {

更新2

替换：

$idnumber = mysqli_real_escape_string( $con, $param1 );
$Name = mysqli_real_escape_string( $con, $param2 );
$Job = mysqli_real_escape_string( $con, $param3 );
$Monday = mysqli_real_escape_string( $con, $param4 );
$Tuesday = mysqli_real_escape_string( $con, $param5 );
$Wednesday = mysqli_real_escape_string( $con, $param6 );
$Thursday = mysqli_real_escape_string( $con, $param7 );
$Friday = mysqli_real_escape_string( $con, $param8 );

使用：

$idnumber = $_POST['userId'][0];
$Name = $_POST['name'][0];
$Job = $_POST['job'][0];
$Monday = $_POST['monday'][0];
$Tuesday = $_POST['tuesday'][0];
$Wednesday = $_POST['wednesday'][0];
$Thursday = $_POST['thursday'][0];
$Friday = $_POST['friday'][0];

更新结束2

<强>更新

添加此行代码以转储正在提交的内容：

var_export($_POST);

不要使用foreach。

改变所有的foreach：

$param2 = $_POST['name'];
$param3 = $_POST['job'];
$param4 = $_POST['monday'];
$param5 = $_POST['tuesday'];
$param6 = $_POST['wednesday'];
$param7 = $_POST['thursday'] ;
$param8 = $_POST['friday'];

要：

$param2 = $_POST['name'];
$param3 = $_POST['job'];
$param4 = $_POST['monday'];
$param5 = $_POST['tuesday'];
$param6 = $_POST['wednesday'];
$param7 = $_POST['thursday'] ;
$param8 = $_POST['friday'];

使用生成的表
