我正在使用laravel并尝试通过ajax使用post保存数据，但数据未保存在数据库中。我收到以下错误：jquery.min.js：2 POST http://localhost:8000/admin/products/attributes/add 500(内部服务器错误(。我的代码如下：
视图：
<script>
$("#add_attributes_info").click(function(e){
e.preventDefault();
$.ajax({
type: "POST",
url: '/admin/products/attributes/add',
data: $('#frmattributes').serialize(),
success: function(msg) {
console.log('success'+msg);
}
});
});
</script>
<form action="#" id="frmattributes" method="POST">
<h3 class="tile-title">Add Attributes To Product</h3>
<div class="row">
<div class="col-md-4">
<div class="form-group">
<label for="values">Select an value <span class="m-l-5 text-danger"> *</span></label>
<select id="attribute_values" name="value" class="form-control custom-select mt-15">
</select>
</div>
</div>
</div>
<div class="row">
<div class="col-md-4">
<div class="form-group">
<label class="control-label" for="quantity">Quantity</label>
<input class="form-control" name="quantity" type="number" id="quantity"/>
</div>
</div>
<div class="col-md-4">
<div class="form-group">
<label class="control-label" for="price">Price</label>
<input class="form-control" name="price" type="text" id="price"/>
<small class="text-danger">This price will be added to the main price of product on frontend.</small>
</div>
</div>
<div class="col-md-12">
<button class="btn btn-sm btn-primary" id="add_attributes_info">
<i class="fa fa-plus"></i> Add
</button>
</div>
</div>
</form>
控制器：
public function addAttribute(Request $request)
{
$productAttribute = ProductAttribute::create($request->data);
if ($productAttribute) {
return response()->json(['message' => 'Product attribute added successfully.']);
} else {
return response()->json(['message' => 'Something went wrong while submitting product attribute.']);
}
}
你应该使用：
$productAttribute = ProductAttribute::create($request->all());
但是，您应该记住，如果没有验证，这是非常危险的。
您应该添加输入验证，然后使用：
$productAttribute = ProductAttribute::create($request->validated());
使用$request->all();
public function addAttribute(Request $request)
{
$productAttribute = ProductAttribute::create($request->all());
if ($productAttribute) {
return response()->json(['message' => 'Product attribute added successfully.']);
} else {
return response()->json(['message' => 'Something went wrong while submitting product attribute.']);
}
}
PS ：我做了一些更改以使其正常工作
希望这个帮助

因此，在控制器中，将$request->data更改为：
$productAttribute = ProductAttribute::create($request->all());
或者还要检查请求包含的内容，在创建之前，您可以使用以下方法进行检查：
dd($request->all());
