Question

我想在一个提交中更新表行。但我不知道该怎么做。

这是我的代码

<form  method="POST" action="<?php $_PHP_SELF ?>">
    <div class="col-md-7" style="margin-left:370px; height:auto;">
    <h3>Service-Level-Agreement</h3>
    <?php

        $query = "select * from tblsla";
        $request = mysql_query($query)or die(mysql_error());?>
        <table class="table table-hover" style="width:auto;">
        <tr>    
                <th>Category</th>
                <th>Easy</th>
                <th>Moderate</th>
                <th>Difficult</th>
                <th></th>
                </tr>
        <?php while($row = mysql_fetch_array($request)){
        ?>
        <tbody>
            <tr>
                <td><?php echo $row['category']; ?></td>

                <td><input type="text" class="form-control" style="width:50px;" name="easySla"/></td>   
                <td><input type="text" class="form-control" style="width:50px;" name="modSla"/></td>    
                <td><input type="text" class="form-control" style="width:50px;" name="difSla"/></td>    
                    <td>Days</td>
            </tr>
        </tbody>
        <?php
        }

?>  
    </table>
    <input type="submit" name="submit" id="submit" value="Edit SLA" class="btn btn-success"/>
    </div>

        <input type="hidden"  name="idUser" value="<?php echo $row['id'];?>" />
    </form>

PHP

<?php
    $easy = $_POST["easySla"];
$mod = $_POST["modSla"];
$diff = $_POST["diffSla"];


if(is_int($easy) AND is_int($mod) AND is_int($diff)){
    echo " Invalid Inputs ";
    }
else
  {
  $sql = "UPDATE tblsla SET  easySLA = '$easy', modSLA = '$mod', difSLA = '$diff' WHERE id = '$id'";
if(isset($_POST['submit'])){
$success = mysql_query($sql) or die (mysql_error());
}
if ($success == TRUE){
    ?>
        <script>
            alert('You have successfully update account.');
        </script>

    <?php
}
  }

?>

这是我想要发生的图像 This is what im trying to do.

非常感谢你！

你有几个同名的输入。
在输入名称中使用数组

尝试这样的事情：

 <form  method="POST" action="<?php $_PHP_SELF ?>">
        <div class="col-md-7" style="margin-left:370px; height:auto;">
            <h3>Service-Level-Agreement</h3>
            <?php

            $query = "select * from tblsla";
            $request = mysql_query($query)or die(mysql_error());?>
            <table class="table table-hover" style="width:auto;">
                <tr>
                    <th>Category</th>
                    <th>Easy</th>
                    <th>Moderate</th>
                    <th>Difficult</th>
                    <th></th>
                </tr>
                <?php while($row = mysql_fetch_array($request)){
                    ?>
                    <tbody>
                    <tr>
                        <td><?php echo $row['category']; ?></td>

                        <td><input type="text" class="form-control" style="width:50px;" name="easySla[]"/></td>
                        <td><input type="text" class="form-control" style="width:50px;" name="modSla[]"/></td>
                        <td><input type="text" class="form-control" style="width:50px;" name="difSla[]"/></td>
 <td>  <input type="hidden"  name="idUser[]" value="<?php echo $row['id'];?>" /></td>
                        <td>Days</td>

                    </tr>
                    </tbody>
                <?php
                }

                ?>
            </table>

            <input type="submit" name="submit" id="submit" value="Edit SLA" class="btn btn-success"/>
        </div>


    </form>

在你的php中你有一个包含所有行的数组。您需要遍历此数组并在数据库中插入数据。

试试这样：

  if (isset($_POST['submit'])) {
$count = count($_POST['easySla']); //get total number of array element
for ($i = 0; $i < $count; $i++) { // loop through array and assign values in variable and insert itin database
    $easy = $_POST['easySla'][$i];
    $mod = $_POST["modSla"][$i];
    $diff =$_POST["difSla"][$i];
    $id = $_POST["idUser"][$i];
    if (is_numeric($easy) && is_numeric($mod) && is_numeric($diff)) {

        $sql = "UPDATE tblsla SET  easySLA = '$easy', modSLA = '$mod', difSLA = '$diff' WHERE id = '$id'";
        $success = mysql_query($sql) or die (mysql_error());
        if ($success == false) {
            break;
        }
    } else {

        echo " <script>
               alert('invalid input not a number.');
               </script>";
        header("location: yourfile_name.php");
    }
}
if ($success) {
    echo " <script>
      alert('You have successfully update account.');
    </script>";
    header("location: yourfile_name.php");
} else {
    echo " <script>
    alert('You have errors.');
     </script>";
    header("location: yourfile_name.php");
}

}

您可以使用循环更新表中具有不同数据或相同数据的所有行...

如果所有行都有不同的数据，则在数组中获取该数据并开始使用该数组长度循环，在该循环中编写查询以更新每行中的数据。

Ex：$ array = [[row1] [row2] [row3]] for length of length $ array { $ query =“update table set row1 ='row1'的数据”，row2 ='row2的数据'...“enter code here }

在提交时更新多行
