这是我的代码的一部分
@foreach($fields as $field)
<div class="flex-row d-sm-inline-flex w-100 mt-1" dir="rtl">
<input type="text" class="form-control w-25" name="{{$field->id}}field" id="{{$field->id}}field" aria-describedby="emailHelp" placeholder="{{$field->name}}" />
<input type="text" class="form-control w-50" name="{{$field->id}}description" id="{{$field->id}}description" aria-describedby="emailHelp" placeholder="{{$field->description}}" />
<button type="submit" class="btn btn-primary" name="submitbutton" id="del-field" value="del-field">پاک کردن فیلد</button>
</div>
@endforeach
这部分展示了我产品的各个领域。 我为每个字段添加一个按钮来删除该字段。问题是，在获得该字段的 id 之前我无法删除该字段，那么如何从 foreach 循环获取 id 到我的 Controller ？

和我的 Controller
public function update(Request $request, $id)
{
switch($request->input('submitbutton')) {
case 'save1':
$user = Auth::user();
$products = Product::findOrFail($id);
$destinationPath = public_path(). '/image/products/';
$avatarName = $products->id . 'product1' . '.' . 'jpg';
request()->image1->move($destinationPath, $avatarName);
return Redirect::back();
break;
case 'save2':
$user = Auth::user();
$products = Product::findOrFail($id);
$destinationPath = public_path(). '/image/products/';
$avatarName = $products->id . 'product2' . '.' . 'jpg';
request()->image2->move($destinationPath, $avatarName);
return Redirect::back();
break;
case 'save3':
$user = Auth::user();
$products = Product::findOrFail($id);
$destinationPath = public_path(). '/image/products/';
$avatarName = $products->id . 'product3' . '.' . 'jpg';
request()->image3->move($destinationPath, $avatarName);
return Redirect::back();
break;
case 'add-field':
$products = Product::findOrFail($id);
$products->fields()->create();
return Redirect::back();
break;
case 'del-field':
return Redirect::back();
break;
}
}
最佳答案
<script>
$(document).ready(function(){
var CSRF_TOKEN = $('meta[name="csrf-token"]').attr('content');
$("#del-field").click(function(){
$.ajax({
/* the route pointing to the update function */
url: '/',
type: 'POST',
/* send the csrf-token and the input to the controller */
data: {_token: CSRF_TOKEN, id:$(this).val()},
dataType: 'JSON',
/* remind that 'data' is the response of the Controller */
success: function (data) {
}
});
});
});
</script>
