Step 1 – Install Laravel 10/9 Application

In step 1, open your terminal and navigate to your local web server directory using the following command:

//for windows user
cd xampp/htdocs

//for ubuntu user
cd var/www/html

Then install laravel latest application using the following command:

composer create-project --prefer-dist laravel/laravel LaravelApiFile

Step 2 – Configuring Database Details

In step 2, open your downloaded laravel app into any text editor. Then find .env file and configure database detail like following:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=db name
DB_USERNAME=db user name
DB_PASSWORD=db password

Step 3 – Create File Model & Migration

In step 3, open command prompt and navigate to your project by using the following command:

cd / LaravelApiFile

Then create model and migration file by using the following command:

php artisan make:model File -m

The above command will create two files into your laravel file upload tutorial app, which is located inside the following locations:

• /app/Models/File.php
• /database/migrations/create_files_table.php

So, find create_files_table.php file inside /database/migrations/ directory. Then open this file and add the following code into function up() on this file:

    public function up()
    {
        Schema::create('files', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('path');
            $table->timestamps();
        });
    }

Now, open again your terminal and type the following command on cmd to create tables into your selected database:

php artisan migrate

Step 4 – Create API File Upload Routes

In step 4, open your api.php file, which is located inside routes directory. Then add the following routes into web.php file:

use App\Http\Controllers\API\FileUploadController;

Route::post('uploading-file-api', [FileUploadController::class, 'upload']);

Step 5 – Creating API File Upload Controller

In step 5, create API file upload controller by using the following command:

php artisan make:controller API\FileUploadController

The above command will create FileUploadController.php file, which is located inside /app/Http/Controllers/API directory.

The following laravel validation rules will validate file before upload/save into database:

       $validator = Validator::make($request->all(),[ 
              'file' => 'required|mimes:doc,docx,pdf,txt,csv|max:2048',
        ]);   
 
        if($validator->fails()) {          
            
            return response()->json(['error'=>$validator->errors()], 401);                        
         }  

Note that, if you want to upload image file via api using postman. So, you can do it with adding the following validation rules with $validator:

'file'  => 'required|mimes:png,jpg,jpeg,gif|max:2048',

Then add the below given code into API\FileController.php file:

<?php

namespace App\Http\Controllers\API;

use App\Http\Controllers\Controller;

use App\Models\File;

use Validator;

use Illuminate\Http\Request;

class FileUploadController extends Controller
{
    public function upload(Request $request)
    {
 
       $validator = Validator::make($request->all(),[ 
              'file' => 'required|mimes:doc,docx,pdf,txt,csv|max:2048',
        ]);   
 
        if($validator->fails()) {          
            
            return response()->json(['error'=>$validator->errors()], 401);                        
         }  
 
  
        if ($file = $request->file('file')) {


            $path = $file->store('public/files');
            $name = $file->getClientOriginalName();
 
            //store your file into directory and db
            $save = new File();
            $save->name = $file;
            $save->store_path= $path;
            $save->save();
              
            return response()->json([
                "success" => true,
                "message" => "File successfully uploaded",
                "file" => $file
            ]);
  
        }
 
  
    }
}

The following single line of code will upload files inside storage/app/public/files directory:

        $path = $request->file('file')->store('public/files');

Step 6 – Start Development Server

Finally, open your command prompt again and run the following command to start development server for your laravel file upload via api application:

php artisan serve

Step 7 – Run this App On PostMan

In step 7, open postman app and call api with file parameter:

http://127.0.0.1:8000/uploading-file-api

The uploading file via api using postman will look like:

Note that, in this example, the file will be upload on the following path – storage/app/public/files.
