Yii2 Cookie not generating

Question

I am trying to set the cookie but cookie is not getting saved. Below is what I have tried:

$cookies = Yii::$app->response->cookies;

$cookies->add(new \yii\web\Cookie([
        'name' => 'abc',
        'value' => 'xyz',
        'expire' => time() + 86400 * 365,
]));

$cookies1 = Yii::$app->request->cookies;

if ($cookies1->has('abc'))
        $cookieValue = $cookies1->getValue('abc');

echo 'value : '.$cookieValue;

echo '<pre>'; print_r($_COOKIE);

$cookieValue does not hold any value. Cookie isn't generated. What am I doing wrong?

Answer 1

Your code is fine. Your problem is that you are trying to set and then get the cookie in the same request.

Your browser has not yet received the response, so it has not had the chance to add the cookie before you try to read it out.

You just need to set and then fetch the cookie in separate requests:

public function actionSetCookie() {

    $cookies = Yii::$app->response->cookies;

    $cookies->add(new \yii\web\Cookie([
        'name' => 'abc',
        'value' => 'xyz',
        'expire' => time() + 86400 * 365,
    ]));

    echo 'Cookie set!';
}

public function actionGetCookie() {

    $cookies1 = Yii::$app->request->cookies;

    if ($cookies1->has('abc'))
        $cookieValue = $cookies1->getValue('abc');

    echo 'value : '.$cookieValue;
}
