Schema::create('files', function (Blueprint $table) {
$table->id();
$table->string('name');
$table->string('path');
$table->timestamps();
});
}
Then, open again command prompt and run the following command to create tables into database:

<?php
namespace App\Http\Controllers;

}
public function store(Request $request)

$name = $request->file('file')->getClientOriginalName();
$path = $request->file('file')->store('public/files');
$save = new File;
$save->name = $name;
$save->path = $path;
return redirect('file-upload')->with('status', 'File Has been uploaded successfully in laravel');
}
}

$path = $request->file('file')->store('public/files');
Step 6 – Create File Upload Form
Now, create file upload form in blade view file for display file upload form and submit to the database.

<!DOCTYPE html>
<html>
<head>
<title>Laravel 9 File Upload Example - Tutsmake.com</title>
<meta name="csrf-token" content="{{ csrf_token() }}">
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
</head>
<body>
<div class="container mt-4">
<h2 class="text-center">File Upload in Laravel 9 - Tutsmake.com</h2>
<form method="POST" enctype="multipart/form-data" id="upload-file" action="{{ url('store') }}" >
<div class="row">
<div class="col-md-12">
<div class="form-group">
<input type="file" name="file" placeholder="Choose file" id="file">
@error('file')
<div class="alert alert-danger mt-1 mb-1">{{ $message }}</div>
@enderror
</div>
</div>
<div class="col-md-12">
<button type="submit" class="btn btn-primary" id="submit">Submit</button>
</div>
</div>
</form>
</div>
</div>
</body>
</html>

@error('file')
<div class="alert alert-danger mt-1 mb-1">{{ $message }}</div>
@enderror
