wrong multilanguage url from module about yii2-localeurls

[mikehaertl]

I don't use that user module. Does it work without it? Do you have to add any URL configuration for that module?

As I understand, the problem arises precisely when called from any module. Looks like as Yii2 bug.
In addition, there is a problem when using links with data-method=POST. After redirect the request is converted to GET. I think this is also a Yii bug.
But if you will have a decision it will be very good.
The bug is in this application

Hmm. I've used it from modules and had no problems so far. But I can check again.

About the data-method POST links: They should already point to the correct language URL. Because when you load the page, which contains such a link, you should already be redirected to your language. So this should never be a problem.

I think, that dektrium/yii2-user have bad realisation. Me need this solution and I will see what not work there. Maybe fix it.

Generate promlem this:
https://github.com/yiisoft/yii2/blob/master/framework/helpers/BaseUrl.php#L132-L138

It is occurs bacause this
https://github.com/codemix/yii2-localeurls#example-language-selection-widget

$route = Yii::$app->controller->route; // <---- THIS
$appLanguage = Yii::$app->language;
$params = $_GET;
//......

In $route we get wrong route if the module is activated. (e.g. dektrium/yii2-user).

As second version it is Yii bug somewhere in that place where I have pointed above.

Yii::$app->controller->route // MAY BE THIS IS BUG!

Or this on generate
https://github.com/yiisoft/yii2/blob/master/framework/helpers/BaseUrl.php#L132-L138

FOR FIX. Need use additional normalize in language switcher. It's bad hack but it's working.

$route = Yii::$app->controller->route;
$moduleId = Yii::$app->controller->module->getUniqueId();
$params = $_GET;

if($moduleId) {
    $route = strpos($route, $moduleId) == 0 ? substr($route, strlen($moduleId) + 1) : $route;
}

array_unshift($params, $route);

$localeUrlsLanguages = Yii::$app->localeUrls->languages;
foreach ($localeUrlsLanguages as $language) {
    $params['language'] = $language;

    $label = self::label($language);
    if ($label === null) {
        throw new yii\base\InvalidConfigException('Language translate not support');
    } else {
        $this->items[] = [
            'label' => $label,
            'url' => $params,
        ];
    }
}
parent::init();

Late with my the project, so who can write this bug in the Community framework. Good by!

[mikehaertl]

I think, all you have to change is to add a / in front of the route:

<?php
$route = '/'.Yii::$app->controller->route;

I've tested it here and it works, but there may be situations where it's still making problems, not sure.

@wartur Can you confirm, that this fix works for you?

[wartur]

@mikehaertl yea! it's work! Thanks. It's good implementation.

Now I publick own Langage Switcher. I get image from Joomla Langage switcher. If you want, you can set your own images.

It's my draft style

}

.language-switcher .container{
    text-align: right;
    position: relative;
    margin-top: -20px;
    z-index: 2;
}

.language-switcher ul{
    margin: 0;
    padding: 0;
    list-style: none;
}

.language-switcher li{
    display: inline-block;
    margin-left: 5px;
    margin-right: 5px;
    width: 25px;
    text-align: center;
}

.language-switcher li.active {
    /*border-bottom: red medium solid;*/
    background-color: #222;
    border: #080808 1px solid;

    -webkit-border-bottom-right-radius: 5px;
