Hello Artisan
In this tutorial i will discuss about dynamically integrate multiple input fields and submit to database with jquery and laravel. We can optically discern addremove multiple input fields dynamically with jquery laravel from scratch so that we can understand facilely.
You can utilize jQuery only to do laravel integrate more fields example in your application. But in this example i will utilize handlebars js as well as jQuery to engender laravel dynamic form fields validation example.
I additionally validate form and then preserve it into database. Sometimes we require it in our application like gregarious list field or task list etc. That situation we can engender this integrate dynamically more then one fields with laravel jQuery and handlebars js.
Simply in this example tutorial i will utilize a Task model to preserve form data that contains two filed. one is task_name and other is cost. Then we preserve it into database. Visually perceive the preview of this tutorial.
Task From
Step 1 : Install Laravel Application
I am going to show you from scratch, So we require to get fresh current Laravel 7.x version application using bellow command, So open your terminal and run
composer create-project --prefer-dist laravel/laravel blog
Step 2: Create Task Table and Model
We are going to create add more dynamic field application for task list. So we have to create migration for task list table using Laravel 7.x php artisan command, so first fire bellow command
php artisan make:model Task -m
database/migrations/create_task_table
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateTasksTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('tasks', function (Blueprint $table) {
$table->id();
$table->string('task_name');
$table->integer('cost');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schem
As we have to save add more input field data in our database to we need to setup our Task model.
app/Task.php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Task extends Model
{
protected $guarded = [];
}
Step 3: Create 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. As this is a example tutorial so i won't use any controller. I simply do it from web.php file.
routes/web.php
use App\Task;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;
Route::get('/', function () {
return view('welcome');
})->name('task');
Route::post('/',function(Request $request) {
$request->validate([
'task_name' => 'required',
'cost' => 'required'
]);
$count = count($request->task_name);
for ($i=0; $i < $count; $i++) {
$task = new Task();
$task->task_name = $request->task_name[$i];
$task->cost = $request->cost[$i];
$task->save();
}
return redirect()->back();
});
Step 4: Create Blade File
Now we need to show our add more field form in our welcome blade file. In this step we have to create just welcome.blade.php blade file.
So let's just create following file and put bellow code.
resources/views/welcome.blade.php
<!DOCTYPE html>
<html lang="">
<head>
<meta charset="utf-8">
