使用 PHP POP 删除模式删除操作不起作用？

Question

我正在使用 PHP 模式来确认从表中删除记录，但它不起作用。弹出模式即使变成提交也会出现，但不幸的是记录没有被删除。知道为什么无法完成此操作。请为我提供确切的解决方案，我能做些什么来解决问题。<?php  if(isset($_POST['deletedata']))  {      $id = $_POST['delete_id'];    mysqli_query($db, "DELETE FROM gallery WHERE id=$id");    header("Location:gallery.php");   }?><script>  $(document).ready(function() {    $(".deletebtn").on('click', function() {      $(".deletemodal").modal('show');      var deletedId = $(this).closest("tr").find(':first-child').text();      $("#delete_id").val(deletedId);    });  });</script> <!---POP Delete Modal ---> <div class="modal fade" id="deletemodal" class="deletemodal"role="dialog"  aria-hidden="true" ><div class="modal-dialog" > <div class="modal-content"><div class="modal-header">            <button type="button" class="close"             data-dismiss="modal" aria-hidden="true">×</button>            <h2 class="modal-title">Delete Image</h2>        </div>        <form action="gallery.php" method="post" enctype="multipart/form-         data">            <div class="modal-body">                <input type="hidden" name="delete_id"  id="delete_id">                <p>Are you sure you want to delete this image?</p>            </div>            <div class="modal-footer">                <button type="submit" style="margin-right:-5px;"               name="deletedata" class="btn btn-primary" >Yes</button>                <button type="button"  style="margin-top:-2px;" class="btn          btn-default " data-dismiss="modal">No</button>            </div>        </form></div></div> </div>

Answer 1

change edit button with attr id

<input type="button" value="Delete" data-toggle="modal" data- 

target="#deletemodal" class="btn btn-lg btn- 

danger deletebtn" id="deletebtn" id="<?php echo $datarecord["id"]; ?>">

change button event

var deletedId = $(this).attr("id");

Answer 2

您的表单中没有任何带有 'delete_id' 名称和 id 的元素，因此当您提交表单时，没有 $_POST['delete_id']
