Hello Devs, 

In this tutorial, we will learn the Laravel Validation lte field Example

The field under validation must be less than or equal to the given field. The two fields must be of the same type.

Follow this step-by-step guide. 

Solution :

$request->validate([
    'amount' => 'required|lte:100',
]);


Full Example:

Add Route

use App\Http\Controllers\ValidationController;

Route::get('lte',[ValidationController::class,'lteValidation']);
Route::post('store-lte',[ValidationController::class,'lteStore'])->name('store-lte');


Controller : app/Http/Controllers/ValidationController.php 

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class ValidationController extends Controller
{
    public function lteValidation()
    {
        return view('validation.lteValidation');
    }

    public function lteStore(Request $request)
    {
        $request->validate([
            'amount' => 'required',
            'adv_amount' => 'required|lte:amount',
        ]);
    }
}
