Laravel 5.1 How to check for the presence a file in a directory?

Question

I have a form in which users can upload files to the upload folder. In the controller I need to check if the file already exists in the upload directory and if it exists not to allow uploading the same file twice. How can I check this?

Answer 1

Maybe the problem it's that you are checking if the file exists in the root folder of the server.

Try this

    if (file_exists(public_path('uploads/'.$file->getClientOriginalName()))) {
        return redirect()->back()->withInput()->withErrors([' File already exists.']);
    }

Answer 2

如果您的文件存储在“公共”文件夹中，请尝试以下操作：

\File::exists(public_path().'\\uploads\\'.$file->getClientOriginalName())

Answer 3

First you have to mention use File at top of the page in your controller

$imagepath = "1.jpg";

$directoryPath = 'user_img/'.$imagepath;

if(File::exists($directoryPath)){
    //echo "n exist"; die();
} else {  echo "not exists";   }
