未在 laravel 8 中上传的图片未获取 hasFile

Question

我正在尝试上传图像并将其保存到文件夹和数据库中。但是，当我提交表单时，会获取包括图像文件名在内的所有数据，但不会保存图像。在数据库中另存为 null 它做到了；如果条件 returns 为假，当我在图像内部回显时，它没有将图像作为文件获取，为什么？这是代码

Blade

<form class="pt-3" action="{{url('registration_form')}}" method="post">
@csrf
    <div class="form-group">
        <input type="file" id="img" name="image" accept="image/*">
    </div>
    <div class="form-group">
        <input type="text" name="name" class="form-control form-control-lg" placeholder="Enter your name" required>
    </div>
    <div class="form-group">
        <input type="email" name="email" class="form-control form-control-lg" placeholder="Email" required>
    </div>
    <div class="mt-3">
        <input class="btn btn-block btn-primary btn-lg font-weight-medium auth-form-btn" type="submit" value="SIGN UP">
    </div>
    <div class="text-center mt-4 font-weight-light">
        Already have an account? <a href="{{url('login')}}" class="text-primary">Login</a>
    </div>
</form>

控制器

public function registration_form(Request $request)
{
    $user = new User;
        
    if ($request->hasFile('image')) {
        $image_tmp = $request->file('image');
        
        if ($image_tmp->isValid()) {
          
            $image_name = $image_tmp->getClientOriginalName(); //get the image name
            $extension = $image_tmp->getClientOriginalExtension(); //get extention of the image
            $imageName = $image_name . '-' . rand(111, 99999) . '.' . $extension;
            $large_image_path = 'assets/images/profile' . $imageName;
                
            Image::make($image_tmp)->save($large_image_path);
            $user->image = $imageName; 
         }
     }

     $user->save();
}

回显$request数据时

Array
(
    [_token] => 6xqdpIfqWBNMu0nifm91wM1lXpul0BRqoCTtEPmx
    [image] => ERD.png
    [name] => Amelia Alvarado
    [email] => zekihap@mailinator.com
)

你错过了enctype="multipart/form-data"

enctype 属性指定 form-data 提交到服务器时应如何编码。

<form class="pt-3" action="{{url('registration_form')}}" method="post" enctype="multipart/form-data">
</form>
