Question

我需要对表单中的三个字段进行验证。

当我没有提交任何内容时，即使我有要求，它们也会提交到数据库，这会使我的程序崩溃。

<button class="btn btn-info btn-lg" type="button" data-toggle="modal" 
data-target="#myModal" tabindex="-1">Add</button>
<div id="myModal" class="modal fade">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header"><button class="close" type="button" data- 
dismiss="modal">×</button>
<h4 class="modal-title">Add Work Order/Service Request</h4>
</div>
<div class="modal-body">
  <div class="popup">
  <form action="{{ url_for('background_process') }}" method="POST">

           <input type="text" id="name" name="name" required />

            <input type="url" id="url" name="url" required />

            <input type ="text" id="mdp-demo" name= "mdp-demo" required />

                <a href=# id=process_input><button 
 class='btn btn-default'>Submit</button></a>
        </form>
  </div>
  </div>
 </div>
</div>

有人知道原因吗？

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

我使用了相同的代码，但是它给了我

即使我需要进行验证，仍会在表单上提交空字段？
