PHP：两个按钮提交

Question

我一直在尝试提交两个按钮，一个要删除，一个要编辑/添加。 但我似乎无法正确解决。

HTML：

    <!-- Edit/Delete Account Form -->
        <form method="get" action="edit.php" onsubmit="setTimeout('location.reload()');">
          <div id="edit-form" class="modal hide fade">
                    <div class="modal-header">
                        <a class="close" data-dismiss="modal">&times;</a>
                        <h4><?php _e('Edit/Delete Account'); ?></h4>
                    </div>
                    <div class="modal-body">
                        <div id="message"></div>
                            <div class="control">
                <div id="edit-account-form">
    <table id="add-account" class="table">
        <tbody>
            <tr>
            <td valign="middle">
            Account Number
            </td>
            <td>
            <input type="hidden" id="editid" name="editid" value=""/>

            </td>
            </tr>

            </tr>
        </tbody>
</table>
                </div>
                            </div>
                        </div>
                    <div class="modal-footer">
                        <button type="submit" data-complete-text="<?php _e('Done'); ?>" name="add" class="btn btn-primary pull-right"><?php _e('Submit'); ?></button>
                        <p class="pull-left"><button type="submit" name="delete" class="btn btn-primary pull-right"><?php _e('Delete'); ?></button></p>

                    </div>
                </div>
        </form>

PHP：

<?php

    //Account Details
    $number = $_GET['number'];
    $description = $_GET['description'];
    $level01 = $_GET['level01'];
    $level02 = $_GET['level02'];
    $level03 = $_GET['level03'];
    $level04 = $_GET['level04'];
    $id = $_GET['editid'];

    $dbc = mysqli_connect('localhost', 'root', 'root', 'accounting') or die('Connection error!');

    if(isset($_POST['delete'])) { 
     $check = "DELETE FROM accountSlave WHERE `id` = '$id' ";
     mysqli_query($dbc, $check) or die('Database error, delete account!');
     }
    if(isset($_POST['add'])) {      
     //$check = "DELETE FROM accountSlave WHERE `id` = '$id' ";
    $check = "UPDATE accountSlave SET `accountNumber` = '$number', `accountDescription` = '$description', `accountLevel1` = '$level01', `accountLevel2` = '$level02', `accountLevel3` = '$level03', `accountLevel4` = '$level04' WHERE `id` = '$id'";
     mysqli_query($dbc, $check) or die('Database error, add account!');
     }

    header('location:master-accounts.php');

?>

当我有一个查询时，它起作用。 我试过一个查询来添加和删除，它的工作。 但是如果单击删除按钮，我需要提交一个删除，反之亦然。

我按照这篇文章尝试正确使用表单上的多个按钮

任何帮助或建议，将不胜感激！

Answer 1

您需要使用$_GET而不是$_POST 。 应该像

if(isset($_GET['delete'])) { 

和

if(isset($_GET['add'])) { 

因为您的表单提交方法是GET而不是POST

Answer 2

您必须检查按下了哪个按钮，并据此进行操作。

另外，您必须使用$_GET而不是$_POST因为您的form method是GET 。

if(isset($_GET['add'])) {
    // code for add
} elseif(isset($_GET['delete'])) {
    // code for delete
}
