dropdownredirect

A dropdownlist widget which can redirect user based on a selected value

It is a simple widget embedding a dropdownlist to redirect on a selected value. I used this to allow the user to change the language.

Requirements ¶

Tested with yii 1.1

Usage ¶

Put the DropDownRedirect.php file in your components directory.

I'll show you the way I used this. In my main layout file, I wrote :

$this->widget('DropDownRedirect', array(
    'data' => Yii::app()->user->avalaibleLanguages, // data od my dropdownlist
    'url' => $this->createUrl($this->route, array_merge($_GET, array('lang' => '__value__'))), // the url (__value__ will be replaced by the selected value)
    'select' => Yii::app()->user->language, //the preselected value
));

The dropdown is now placed. To handle the url redirection, I wrote in my controller :

public function init() {
        if (isset($_GET['lang']))
            Yii::app()->user->language = $_GET['lang'];
        Yii::app()->user->applyPreferedLanguage();
 
        Yii::app()->name = Yii::t('site', Yii::app()->name);
        parent::init();
    }

The user functions used above are here, in a personnal WebUser :

class WebUser extends CWebUser {
    public function getLanguage() {
        if ($this->getState('lang') == null) {
            $lang = strtolower(substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2));
            $this->setLanguage($lang);
        }
        return $this->getState('lang');
    }
 
    public function setLanguage($lang) {
        $this->setState('lang', $lang);
    }
 
    public function applyPreferedLanguage() {
        Yii::app()->language = $this->getLanguage();
    }
 
    public function getAvalaibleLanguages() {
        return array('en' => Yii::t('site', 'english'), 'fr' => Yii::t('site', 'french'));
    }
}

This works

This version works in Yii 1.1.5:

/**
 * @brief This widget is a dropDown which can redirect to  an url base on selected value via javascript
 */
class DropDownRedirect extends CWidget {
    public $name; // name attribute of the dropdownlist
 
    public $select; // selected value
 
    public $data; // data of the dropdownlist
 
    public $htmlOptions = array(); // options of the dropdownlist
 
    public $url; // url with the string $replacement somewhere, wich will be replaced by the current value
 
    public $replacement = '__value__'; // will be replaced by the value
 
    public function init() {
        if (! isset($this->name))
            $this->name= $this->id;
    }
 
    public function run() {
        if (!isset($this->htmlOptions['id'])) $this->htmlOptions['id'] = $this->id;
                $script = 'window.location = "'.$this->url.'".replace("'.$this->replacement.'", $(this).val());';
                if (!isset($this->htmlOptions['onChange'])) $this->htmlOptions['onChange'] = $script;
                echo CHtml::dropDownList($this->name, $this->select, $this->data, $this->htmlOptions);
    }
}

Doesn't work in Yii 1.1.5

For some reason, this extension stopped working by Yii 1.1.5. Would be great if someone could fix it. :)

Correction..

Since we can't edit our comments, let me correct the criteria select statement:

$Criteria->select = "name";

'id' is not needed, of course. My Project and my Issue controller makes use of the 'name' parameter to determine the active project.

Great work!

I've successfully integrated this with my application where I use it to allow my users to switch active project.

I my Project and Issue controller I have this function:

public function getProjects() {
            $Criteria = new CDbCriteria();
            $Criteria->select = "id, name";
            $results = Project::model()->findAll($Criteria);
            $project_list = array();
            $project_list[''] = '<Switch Project>';
            foreach($results as $result) {
                $project_list[$result->name] = $result->name;
            }
            return $project_list;
        }

I use this code to place the widget:

if (((Yii::app()->controller->id === 'project')||(Yii::app()->controller->id === 'issue')) && (isset($_GET['name']))) {
            $this->widget('DropDownRedirect', array(
                'data' => Yii::app()->controller->getProjects(),
                'url' => $this->createUrl($this->route, array_merge($_GET, array('name' => '__value__'))),
                'select' => '<Switch Project>', //the preselected value
                'htmlOptions' => array('class' => 'operations')
            ));
        }

Thanks a lot!

Oups, I forgot availableLanguages function :)

This is in my WebUser class :

public function getAvalaibleLanguages() {
    return array('en' => Yii::t('site', 'english'), 'fr' => Yii::t('site', 'french'));
}
