Examples

Using Laravel Captcha

Generate a Captcha markup in your Controller:

<?php 

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;

class MyController extends Controller 
{
    public function getExample() 
    {
        return view('myView');
    }

}

Showing a Captcha in a View:

...
@captcha
<input type="text" id="captcha" name="captcha">
 ...

Check user input during form submission:

<?php 

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;

class MyController extends Controller 
{
    public function getExample() 
    {
        return view('myView');
    }

    public function postExample(Request $request)
    {
    	$this->validate($request, [
            'captcha' => 'required|captcha'
        ]);

        // Validation passed
    }
}
