Eine Slideshow

admin — Thu, 29 Mar 2012 16:19:17 +0000

//in einer view-Datei, zeige mir alle Bilder eines Ordners in einer Slideshow an
 $this->widget('ext.slideshow.SlideshowWidget', array('dir' => 'images')); ?>

Dafür laden wir uns mal eine JQuery-Slideshow.
Abspeichern unter extensions/slideshow/assets/slideshow.js.
Der Quellcode dieser Seite zeigt uns die simple Anwendung, die wir nur noch als Widget implementieren müssen.

//extensions.slideshow.SlideshowWidget.php
class SlideshowWidget extends CWidget
{
    public $dir;
    public $width  = 600;
    public $height = 450;
 
    public static $assetsUrl;
 
    public function getImageUrl($file)
    {
        return Yii::app()->baseUrl . '/' . $this->dir . '/' . basename($file);
    }
 
    public function run()
    {   
        $path = str_replace('/', '.', $this->dir);
        $path = Yii::getPathOfAlias('webroot.' . $path);
        $files = CFileHelper::findFiles($path, array('fileTypes' => array('jpg', 'jpeg', 'gif', 'png'), 'level' => 0));
 
        Yii::app()->clientScript->registerScriptFile(self::getAssetsUrl() . '/slideshow.js');
        Yii::app()->clientScript->registerScript('slideshow', "$('.slideshow').cycle({fx: 'fade'});");
 
        Yii::app()->clientScript->registerCss('slideshow', '
            .slideshow { height: ' . $this->height . 'px; width: ' . $this->width . 'px; margin: auto }'
        );
 
        echo '';
        foreach ($files as $file) {
            echo ' . $this->getImageUrl($file) . '" />';
        }
        echo '
';
    }
 
    public static function getAssetsUrl()
    {
        if (self::$assetsUrl === null) {
            self::$assetsUrl = Yii::app()->getAssetManager()->publish(
                Yii::getPathOfAlias('ext.slideshow.assets')
            );
        }
 
        return self::$assetsUrl;
    }
}

  'id' => 'pk',
  'name' => 'string',
  'price' => 'money' //speichert decimal(19,4)
));
 
echo Yii::app()->numberFormatter->formatCurrency($model->price, 'EUR'); //ergibt €1000.00

Brainstorming App

admin — Thu, 02 Feb 2012 19:59:42 +0000

Ganz einfache Sache. Mittels Brainstorming sollen Ideen und Lösungsvorschläge gefunden werden. Jeder kann Fragen, Probleme posten und jeder kann auch Ideen, Kommentare abliefern. Als Datenbank wird hier SQLite verwendet, somit ist keine Installation notwendig.

CDetailView in Sidebar anzeigen

admin — Tue, 24 Jan 2012 17:05:58 +0000

Problem:

die th-Spalte im DetailView ist per CSS 160px breit, passt nicht so einfach in eine schmale Sidebar

Lösung:

class UserInfo extends CWidget
{
  public $user;
 
  public function run()
  {
    Yii::app()->clientScript->registerCss('sidebar', 'table.sidebar th {width: 100px;}');
    $this->widget('zii.widgets.CDetailView', array(
      'data' => $this->user,
      'htmlOptions' => array('class' => 'detail-view sidebar'),
      'attributes' => array(
        'firstname',
        'lastname'
      ),
    ));
  }
}
