Question

我必须通过一次提交在数据库中的不同单元格中提交所有值当我点击提交时，它只插入最后一个学生和最后一个主题标记例子（退缩和物理）：

<tbody>
    <?php
    $query="SELECT *FROM `students` WHERE `standard`='".$standard."'";
    $ex_query=mysql_query($query);
    while($row=mysql_fetch_array($ex_query)) {
        $id=$row['id'];
        $fname=$row['fname'];
        $lname=$row['lname'];
        $rollno = $row['rollno'];
        $standard = $row['standard'];
        $section = $row['section'];
    ?>

                <tr>
                    <th scope="row">1</th>
                    <td><?php echo $fname; ?> <?php echo $lname; ?>
                        <input type="hidden" name="name" value="<?php echo $fname; ?> <?php echo $lname; ?>">
                    </td>
                    <td><?php echo $standard; ?>
                        <input type="hidden" name="standard" value="<?php echo $standard; ?>">
                    </td>
                    <td><?php echo $section; ?>
                        <input type="hidden" name="section" value="<?php echo $section; ?>">
                    </td>
                    <?php  $querysub="SELECT *FROM `subject`";
                            $ex_querysub=mysql_query($querysub);
                            while($row=mysql_fetch_array($ex_querysub))
                                {
                    $id=$row['id'];
                    $subject=$row['subject'];
                 ?>

                    <td><input type="hidden" name="subject" value="<?php echo $subject; ?>"><input type="text" class="form-control col-md-7 col-xs-12" name="marks"></td>
                    <?php } ?>
                    <!-- <td><a href="javascript:void(0)" onClick="edit(<?php echo $id ?>)"><i class="fa fa-edit"></i></a></td>
                    <td><a href="javascript:void(0)" onClick="deldata(<?php echo $id ?>)"><i class="fa fa-trash-o"></i></a></td> -->
                </tr>
            <?php } 
        ?>                              
    </tbody>
</table>
<input type="submit" name="submit">


<?php


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

    $id 
    $name = $_POST['name'];
    $standard = $_POST['standard'];
    $section = $_POST['section'];
    $subject = $_POST['subject'];
    $marks = $_POST['marks'];

    $query="INSERT INTO `marks` (`id` ,`name` ,`standard` ,`section`  ,`subject` ,`marks`) VALUES (NULL, '$name', '$standard', '$section', '$subject', '$marks')";
    $ex_query=mysql_query($query); ?>
    <!-- <script>
        window.location.href="view-standard.php";
    </script> -->   <?php
}
}
?>
</form>

Answer 1

您可以为每个元素名称添加行索引，例如

<tr>
  <th scope="row">1
  </th>
  <td>
    <?php echo $fname; ?> 
    <?php echo $lname; ?>
    <input type="hidden" name="name[]" value="<?php echo $fname; ?> <?php echo $lname; ?>">
  </td>
  <td>
    <?php echo $standard; ?>
    <input type="hidden" name="standard[]" value="<?php echo $standard; ?>">
  </td>
  <td>
    <?php echo $section; ?>
    <input type="hidden" name="section[]" value="<?php echo $section; ?>">
  </td>
  <?php  $querysub="SELECT *FROM `subject`";
$ex_querysub=mysql_query($querysub);
while($row=mysql_fetch_array($ex_querysub))
{
$id=$row['id'];
$subject=$row['subject'];
?>
  <td>
    <input type="hidden" name="subject[]" value="<?php echo $subject; ?>">
    <input type="text" class="form-control col-md-7 col-xs-12" name="marks">
  </td>
  <?php } ?>
  <!-- <td><a href="javascript:void(0)" onClick="edit(<?php echo $id ?>)"><i class="fa fa-edit"></i></a></td>
<td><a href="javascript:void(0)" onClick="deldata(<?php echo $id ?>)"><i class="fa fa-trash-o"></i></a></td> -->
</tr>

然后，当您访问$_POST['name']时，您将获得一个包含所有值的数组，您可以使用循环并将它们插入数据库中。

Answer 2

$i=0;
while ($row = mysql_fetch_assoc($ex_querysub)) {
    ?>
    <td>
        <input type="text" name="form[<?php echo $i; ?>]['name']" value="<?php echo $row['name']; ?>" />
    </td>
    <td>
        <input type="text" name="form[<?php echo $i; ?>]['section']" value="<?php echo $row['section']; ?>" />
    </td>
    .... you got the idea
    <?php

    $i++;
}

始终使用mysql_fetch_assoc代替mysql_fetch_array。

行动本身

<?php

if (isset($_POST['form'])) {
     foreach ($_POST['form'] as $row) {
          $sql = sprintf("INSERT INTO marks SET 
          name = '%s',
          section = '%s'
          ... add all fields here
           ", 
          strip_tags($row['name']), // you should always sanitize your input from user. Or you'll have SQL Injection problems
          strip_tags($row['section']),
          );

          mysql_query($sql);
     }
}

我更喜欢使用第二种形式的INSERT语句http://dev.mysql.com/doc/refman/5.7/en/insert.html。它与UPDATE相似，更容易理解。特别是如果您有大插入查询。通常应该在插入
上跳过主键auto_increment

表格和表格提交
