Laravel saving image to public folder?
提问by Przemek
So I am trying to save uploaded image to laravel/public folder and return src so a path to where the file has been saved, however nothing happens after I choose an image and I get no errors, what might be wrong?
所以我试图将上传的图像保存到 laravel/public 文件夹并返回 src 以便保存文件的路径，但是在我选择图像后没有任何反应并且我没有收到任何错误，可能有什么问题？
public function testing(Request $request) {
if(Input::file())
{
$image = Input::file('img');
$filename = time() . '.' . $image->getClientOriginalExtension();
$path = public_path('images/' . $filename);
Image::make($image->getRealPath())->resize(200, 200)->save($path);
$user->image = $filename;
$user->save();
}
}
<form action="{{ action('BuilderController@testing') }}" enctype="multipart/form-data" role="form" method="POST">
<input id="img" class="form-control filestyle margin images" data-input="false" type="file" data-buttonText="Upload Logo" data-size="sm" data-badge="false" onchange="uploadImage();" />
</form>

Try with move()method?
用move()方法试试？
$filename = time().'.'.request()->img->getClientOriginalExtension();
request()->img->move(public_path('images'), $filename);
$user->image=$filename;
$user->save();

You can easily upload image to public folder as following:
您可以轻松地将图像上传到公共文件夹，如下所示：
$image = $request->file('image');
$input['imagename'] = time().'.'.$image->getClientOriginalExtension();
$destinationPath = public_path('/thumbnail');
$img = Image::make($image->getRealPath());
$img->resize(100, 100, function ($constraint) {
$constraint->aspectRatio();
})->save($destinationPath.'/'.$input['imagename']);
/*After Resize Add this Code to Upload Image*/
$destinationPath = public_path('/');
$image->move($destinationPath, $input['imagename']);
And also you can check it here to resize and upload image:

you need to add name="img"on your form.
你需要name="img"在你的表格上添加。

First, you have not added file input name
首先，您没有添加文件输入名称
if(Input::file('inputname')){
//
}
Secondly,
其次，
For laravel-5.3 You can determine if a file is present on the request using the hasFile method
对于 laravel-5.3，您可以使用 hasFile 方法确定请求中是否存在文件
if ($request->hasFile('photo')) {
//
}
And you can retrieve the uploaded file
您可以检索上传的文件
$file = $request->file('photo');
You can find the complete documentation here
