Input::file() returning null Laravel
提问by noahdotgansallo
I've been writing an uploading script and even though I'm using the Laravel built in function Input::file() it still returns null. I am going to post my Home Controller code.
我一直在编写一个上传脚本，即使我使用的是 Laravel 内置函数 Input::file() 它仍然返回 null。我将发布我的家庭控制器代码。
public function handleUpload()
{
$user = Auth::user();
$username = $user->username;
$userId = $user->id;
$path_to_users = "users";
$user_profile_img = 'users/'.$username.$userId.'/'.$username.'image001.jpg';
$user_path_profile = "users/$username$userId";
$user_image_name = $username.'image001.jpg';
if(file_exists($path_to_users))
{
if(file_exists("$user_path_profile")){
$file = Input::file('profile')->move("$user_path_profile/", $user_image_name);
} else {
mkdir("$user_path_profile");
$file = Input::file('profile')->move("$user_path_profile/", $user_image_name);
}
} else {
mkdir("users");
mkdir("$user_path_profile");
$file = Input::file('profile')->move("$user_path_profile/", $user_image_name);
}
}
When I die(var_dump(Input::file('profile'))) returns null which means it is basically not taking in my file as an actual file. When I do die(var_dump(Input::get('profile'))) it returns the image name meaning that my uploading script is working but the Laravel backend is failing. Is this true, or am I just missing something?
当我死时(var_dump(Input::file('profile'))) 返回null，这意味着它基本上不会将我的文件作为实际文件。当我执行 die(var_dump(Input::get('profile'))) 时，它返回图像名称，这意味着我的上传脚本正在运行，但 Laravel 后端出现故障。这是真的，还是我只是错过了什么？
Here is my HTML form stuff:
这是我的 HTML 表单内容：
@if($user->id == $userProf->id)
<div class="fileUpload button-success pure-button">
<span>Upload</span>
<form action="{{action('HomeController@handleUpload')}}" method="POST" enctype="multipart/form-data">
<input type="file" name="profile" class="upload" />
</form>
</div>
@endif

I had the same problem in a normal form. I forgot to add:
我在正常形式下遇到了同样的问题。我忘了补充：
enctype="multipart/form-data"

I had the same issue and realised I had left out something in the form. Use the built in laravel forms as it will automatically add CRSF protection (see http://laravel.com/docs/html). Anyway - you need to add 'files' => trueto the top of the form - so for example in the blade template it could look like:
我遇到了同样的问题，并意识到我在表格中遗漏了一些东西。使用内置的 laravel 表单，因为它会自动添加 CRSF 保护（请参阅http://laravel.com/docs/html）。无论如何 - 您需要添加'files' => true到表单的顶部 - 例如在刀片模板中它可能看起来像：
{{ Form::open( array('route' => 'admin.store', 'class'=>'form-horizontal', 'files' => true)) }}
{{Form::file('file')}}
{{ Form::submit('Submit', array('class' => 'btn btn-info')) }}
{{ Form::close() }}

Looking at your code, it should work, so it looks you have a problem in anything else, maybe even your view. I just built two routers to test it here:
查看您的代码，它应该可以工作，因此看起来您在其他任何方面都有问题，甚至可能是您的观点。我刚刚构建了两个路由器来测试它：
Route::post('file', function() {
echo "<pre>";
var_dump(Input::file('profile'));
echo "</pre>";
});
Route::get('upload', function() {
return Form::open(array('url' => '/file', 'files' => true)) .
Form::file('profile') .
Form::submit('upload');
});
You can use them as a baseline to, step-by-step, make yours work too.
您可以将它们用作基线，逐步使您的工作也能正常工作。
