Add/remove multiple input fields dynamically with Jquery Laravel 5.8

Preview:

Step 1 : Install Laravel

I am going to show you scratch, So we require to get fresh current Laravel 5.8 version application using bellow command, So open your terminal OR command prompt and run bellow command:

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

Step 2: Database Configuration

In this step we have to make database configuration for example database name, username, password etc for our application of laravel 5.8. So let’s open .env file and fill all details like as bellow:

.env

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=here your database name(blog)
DB_USERNAME=here database username(root)
DB_PASSWORD=here database password(root)

Step 3: Create product_stocks Table and Model

we are going to create add more dynamic field application for product_stocks. so we have to create migration for product_stocks table using Laravel 5.8 php artisan command, so first fire bellow command:

php artisan make:migration create_product_stocks_table

After this command you will find one file in following path database/migrations and you have to put bellow code in your migration file for create articles table.

<?php
use IlluminateSupportFacadesSchema;
use IlluminateDatabaseSchemaBlueprint;
use IlluminateDatabaseMigrationsMigration;
class CreateProductStocksTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('product_stocks', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('name');
            $table->integer('qty');
            $table->integer('price');
            $table->timestamps();
        });
    }
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('product_stocks');
    }
}

Now run migration my following command:

php artisan migrate

After creating table we have to create model for “product_stocks” table so just run bellow command and create new model:

php artisan make:model ProductStock

Ok, so after run bellow command you will find app/ProductStock.php and put bellow content in ProductStock.php file:

app/ProductStock.php

<?php
namespace App;
use IlluminateDatabaseEloquentModel;
class ProductStock extends Model
{
    public $table = "product_stocks";
    public $fillable = ['name', 'qty', 'price'];
}

Step 4: Add Routes

In this is step we need to add two route for add more fields example. so open your routes/web.php file and add following route.

routes/web.php

Route::get("addmore","ProductAddMoreController@addMore");
Route::post("addmore","ProductAddMoreController@addMorePost")->name('addmorePost');

Step 5: Create ProductAddMoreController

Here, now we should create new controller as ProductAddMoreController if you haven’t created. So run bellow command and create new controller. bellow controller for create resource controller.

php artisan make:controller ProductAddMoreController

After bellow command you will find new file in this path app/Http/Controllers/ProductAddMoreController.php.

In this controller will create seven methods by default as bellow methods:

1)addMore()

2)addMorePost()

So, let’s copy bellow code and put on ProductAddMoreController.php file.

app/Http/Controllers/ProductAddMoreController.php

<?php
namespace AppHttpControllers;
use IlluminateHttpRequest;
use AppProductStock;
class ProductAddMoreController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return IlluminateHttpResponse
     */
    public function addMore()
    {
        return view("addMore");
    }
    /**
     * Display a listing of the resource.
     *
     * @return IlluminateHttpResponse
     */
    public function addMorePost(Request $request)
    {
        $request->validate([
            'addmore.*.name' => 'required',
            'addmore.*.qty' => 'required',
            'addmore.*.price' => 'required',
        ]);
        foreach ($request->addmore as $key => $value) {
            ProductStock::create($value);
        }
        return back()->with('success', 'Record Created Successfully.');
    }
}

Step 6: Create Blade File

now we move in last step. In this step we have to create just addMore.blade.php blade file.

So let’s just create following file and put bellow code.

resources/views/addMore.blade.php

<!DOCTYPE html>
<html>
<head>
    <title>Add/remove multiple input fields dynamically with Jquery Laravel 5.8</title>
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" />  
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
</head>
<body>
<div >
    <h2 align="center">Add/remove multiple input fields dynamically with Jquery Laravel 5.8</h2> 
    <form action="{{ route('addmorePost') }}" method="POST">
        @csrf
        @if ($errors->any())
            <div >
                <ul>
                    @foreach ($errors->all() as $error)
                        <li>{{ $error }}</li>
                    @endforeach
                </ul>
            </div>
        @endif
        @if (Session::has('success'))
            <div >
                <a href="#"  data-dismiss="alert" aria-label="close">×</a>
                <p>{{ Session::get('success') }}</p>
            </div>
        @endif
        <table  id="dynamicTable">  
            <tr>
                <th>Name</th>
                <th>Qty</th>
                <th>Price</th>
                <th>Action</th>
            </tr>
            <tr>  
                <td><input type="text" name="addmore[0][name]" placeholder="Enter your Name"  /></td>  
                <td><input type="text" name="addmore[0][qty]" placeholder="Enter your Qty"  /></td>  
                <td><input type="text" name="addmore[0][price]" placeholder="Enter your Price"  /></td>  
                <td><button type="button" name="add" id="add" >Add More</button></td>  
            </tr>  
        </table> 
        <button type="submit" >Save</button>
    </form>
</div>
<script type="text/javascript">
    var i = 0;
    $("#add").click(function(){
        ++i;
        $("#dynamicTable").append('<tr><td><input type="text" name="addmore['+i+'][name]" placeholder="Enter your Name"  /></td><td><input type="text" name="addmore['+i+'][qty]" placeholder="Enter your Qty"  /></td><td><input type="text" name="addmore['+i+'][price]" placeholder="Enter your Price"  /></td><td><button type="button" >Remove</button></td></tr>');
    });
    $(document).on('click', '.remove-tr', function(){  
         $(this).parents('tr').remove();
    });  
</script>
</body>
</html>

Now you can run this full example using quick run command of laravel like as bellow:

php artisan serve

Now you can open bellow URL on your browser:

http://localhost:8000/addmore

I hope it can help you…
