How to Show Cookie Policy Consent or GDPR Popup in Laravel using Cookie.

Cookie in Laravel

You can use the cookie in Laravel using the Helper method `cookie()` or method available with Request/Response Object or `Cookie` facade.

$request->cookie('name');

OR

use Illuminate\Support\Facades\Cookie;

Cookie::get('name');

To get more clarity on how to use the cookie in Laravel with an example to show cookie consent popup on your Laravel website and hide/remove it once you accept the policy.

Cookie Policy Consent Popup in Laravel

First, create and a Cookie Consent popup as notification to the footer section of your Laravel main blade template file. 

<div class="cookies-block">

        <h5>This website uses cookies</h5>

        <p>We use cookies to improve your experience and deliver personalised content. By using this website, you agree to our <a href="javascript:void()">Cookie Policy</a>.</p>

        <button class="okay-btn">ACCEPT</button>

 </div>

First, Now, Javascript snippet to capture click on the `ACCEPT` button, send ajax request to the server to create a cookie.

$(document).on('click','#footer .cookies-block button', function(e) {

    e.preventDefault();

    $.ajax({

        method: 'GET',

        url: '/cookie',

        data : {

            'name' : 'accept-cookie',

            'value' : true

        },

        success: function (response) {

            $('#footer').find('.cookies-block').hide();

        },

        error: function (error) {

            alert('Error: Please refresh the page');

        },

    });

});

Now you have to create a POST route with the public permission that maps to a method in the controller which returns the response with the cookie. 

//in route/web.php

Route::post('/cookie', 'PagesController@setCookie');

//in app/Http/Controllers/PagesController.php

public function setCookie(Request $request)

{

    return response('success')->cookie('accept-cookie', true, config('constants.COOKIE_ACCEPT_LIFETIME'));

}

Once Ajax request got success response, it creates a cookie, like as above with name `accept-cookie`.
you can check it in your browser's debug panel (press F12).
As now cookie stored in your browser now you make a check for the user who has already accepted the policy i.e. accept-cookie is stored or not. hence the consent popup can be wrap in check:

//in the main layout template
@if (!request()->cookie('accept-cookie')) //check if cookie not stored
    <div class="cookeies-block">
        <h5>This website uses cookies</h5>
        <p>We use cookies to improve your experience and deliver personalised content. By using this website, you agree to our <a href="javascript:void()">Cookie Policy</a>.</p>
        <button class="okay-btn">OK</button>
    </div>
@endif
