How to upload file code using Laravel

To upload a file using Laravel, you can follow these steps:

Create a new form in your Laravel view with an input field for the file:

<form method="POST" action="{{ route('file.upload') }}" enctype="multipart/form-data">

    <input type="file" name="file">

    <button type="submit">Upload</button>

Define a new route in your routes/web.php file that points to a controller method that will handle the file upload:

Route::post('/file/upload', [App\Http\Controllers\FileController::class, 'upload'])->name('file.upload');

Create a new controller method in FileController that will handle the file upload:

public function upload(Request $request)
    // Validate the uploaded file
        'file' => 'required|file|max:1024', // limit file size to 1 MB

    // Store the uploaded file in the storage/app/public directory
    $path = $request->file('file')->store('public');

    // Generate a URL for the uploaded file
    $url = Storage::url($path);

    // Redirect back with a success message
    return back()->with('success', 'File uploaded successfully: ' . $url);

In the upload() method, we first validate that the uploaded file meets our requirements (in this case, it must be a file and not exceed 1 MB in size). We then use the store() method on the uploaded file to store it in the storage/app/public directory. This directory is publicly accessible, so we can generate a URL for the file using the url() method on the Storage facade. Finally, we redirect back to the form with a success message that includes the URL of the uploaded file.

You can now test the file upload functionality by navigating to the form and selecting a file to upload. If the file meets the validation requirements, it will be uploaded and a success message will be displayed. You can then access the uploaded file at the generated URL.
