Yii2.0 modal pop-up box + ajax submission form

As the title says, we use modal pop-up box + ajax to submit the form. First, we add data-toggle and data-target to the create button of the index view.

The code is as follows:

<?php
echo Html::a(&#39;添加请假单&#39;, [&#39;create&#39;], [&#39;class&#39; => &#39;btn btn-success&#39;,&#39;data-toggle&#39;=>&#39;modal&#39;,&#39;data-target&#39;=>&#39;#ajax&#39;])
?>

Add the following code in the index view to display the modal pop-up box:

<div class="modal bs-example-modal-lg" id="ajax">
 
 <div class="modal-dialog">
  
 <div class="modal-content width_reset" id="tmpl-modal-output-render"> </div>
  
 </div>
 
</div>

The modified effect is as follows

Then we modify the create method in the controller and change render to renderAjax

return $this->renderAjax('create', [
 'model' => $model,
]);

If we want to add form validation, we need to modify _form in views and add the id

<?php $form = ActiveForm::begin([&#39;options&#39; => [&#39;enctype&#39; => &#39;multipart/form-data&#39;],&#39;id&#39;=>&#39;leave-form-self&#39;]) ?>
指向 你的models 在rules添加上验证规则
 
 public function rules()
 {
  return [
   [[&#39;t_leave_date&#39;, &#39;t_days&#39;, &#39;t_reason&#39;, &#39;t_nickname&#39;,&#39;t_leave_enddate&#39;], &#39;required&#39;],
   [[&#39;t_leave_date&#39;, &#39;t_leave_enddate&#39;], &#39;safe&#39;],
   [[&#39;t_days&#39;], &#39;number&#39;],
   [[&#39;t_reason&#39;], &#39;string&#39;],
   [[&#39;type&#39;, &#39;add_time&#39;, &#39;uid&#39;, &#39;update_time&#39;, &#39;status&#39;, &#39;is_shen&#39;], &#39;integer&#39;],
   [[&#39;t_pickup&#39;, &#39;t_nickname&#39;, &#39;t_pass&#39;], &#39;string&#39;, &#39;max&#39; => 20],
   [[&#39;t_img&#39;, &#39;reviewer_user&#39;, &#39;audit_user&#39;], &#39;string&#39;, &#39;max&#39; => 255]
  ];
 }

The effect is as follows

In this way, the ajax submission form is realized
