Under i18n Captcha image disappears by clicking on it

[easyrider7522]

Server: Apache/2.4.16 (Win32) PHP/5.6.12 Yii/2.0.6 (same problem on live Linux server)

Although captchaAction is specified, registerClientScript() generates JS-script with wrong route: "hashKey":"yiiCaptcha/site/captcha" (Should be without site/).

yii\captcha\Captcha is used as widget in the view:

$form->field( $model, 'verifyCode' )->widget( Captcha::className(), [ 'captchaAction' => '/captcha' ]);

Under i18n environment works fine in app's main language but in other languages won't refresh on click.

Failed to reproduce on Yii2 Basic app template. Could you try to reproduce your problem on clean Yii2, please?

It's i18n project with pretty urls support including language identification, which is solved within extended UrlManager. Maybe following will help us both to understand on which side is the issue.

Yii generates following JavaScript for Captcha verification (simplified):

jQuery(document).ready(function () {
    jQuery('#contactform-verifycode-image').yiiCaptcha({
        "refreshUrl":"\/test\/frontend\/web\/ru\/captcha?refresh=1",
        "hashKey":"yiiCaptcha\/\/captcha"
    });
    jQuery('#contact-form').yiiActiveForm([{
            "validate":function (attribute, value, messages, deferred, $form) {
                yii.validation.captcha(value, messages, {
                    "hash":665,
                    "hashKey":"yiiCaptcha/site/captcha",
                    "caseSensitive":false,
                    "message":"Проверочный код введён неверно"
                });
            }
    }], []);
});

If you check the hashKey values in both procedures you can see that different routes were generated by Captcha. The first one is yiiCaptcha//captcha - dunno if its ok, but it seems to work, but the second one yiiCaptcha/site/captcha contains controller name, which is the problem, I think.

At page load the captcha image appears and has src attribute like /test/frontend/web/ru/captcha?v=565771ae05faa, which after click changes to /test/frontend/web/ru/site/captcha?v=565771ae05fab.

No client side JS verification customization was performed.

Looks like your custom URL manager implementation has a problem generating URLs where language isn't specified as in captcha's case.

[easyrider7522]

I do avoid use of default controller name anywhere, that's why the link looks like it is. Still everything works fine.

Solved this by extending CaptchaValidator where the overridden clientValidateAttribute() removes the default controller name from resulting JS. Same does now also my URL Manager.

I don't insist on changes but still believe that CaptchaValidator should create routes using application-provided rules but not own fixed controller/action pattern.

[samdark]

Could you point to where CaptchaValidator creates URL using controller/action directly?

[easyrider7522]

CaptchaValidator.php:94

[samdark]

That has nothing to do with the URL.

[easyrider7522]

Validation fails if I live the controller name there

[easyrider7522]

My point is that if I can call the widget with captchaAction like this:

$form->field( $model, 'verifyCode' )->widget( Captcha::className(), [ 'captchaAction' => '/captcha' ]);

then it must be also possible to set captchaAction of the model rule like this:

public function rules()
{
    return [
        [ 'verifyCode', 'captcha', 'captchaAction' => '/captcha' ]
    ]
}

which is not possible without controller name but leads to the whole problem I faced.

[samdark]

Action should be always specifed in terms of route, not as string.

[easyrider7522]

Anyway, thank you for your attention. You helped me already many times without knowing it, and I think this way think many satisfied Yii programers.

P.S.: This is my navbar "in terms of route" ;-)

echo Nav::widget([
    'options'   => [ 'class' => 'navbar-nav navbar-left' ],
    'items'     => [
        [ 'label' => Yii::t( 'navmenu', 'home'    ), 'url' => [ '/'        ]],
        [ 'label' => Yii::t( 'navmenu', 'about'   ), 'url' => [ '/about'   ]],
        [ 'label' => Yii::t( 'navmenu', 'booking' ), 'url' => [ '/booking' ]],
        [ 'label' => Yii::t( 'navmenu', 'contact' ), 'url' => [ '/contact' ]],
    ],
]);

[samdark]

Yep, that's not correct. Route is controller/action pair, not the resulting URL.
