我是yiibie,我正在从ngo表中检索图像和ngo名称,并能够在所需的页面上显示它们,我想以desc顺序显示Ngo,我的意思是当一个新的ngo注册时它应显示为所需页面上的第一张图像。 为此,这是Ngo控制器

这是视图文件
请求 - &GT; baseURL时;?&GT; /img/ngo-banner.jpg"类=&#34; IMG响应&#34;&GT;
<?php
$cnt= -100;
$nThumbXRow = 4;
foreach($allmodels as $model) {
if ($cnt%$nThumbXRow == 0);
echo "<div class='col-md-3'><div class='thumbnail'>
<img src='" . Yii::app()->request->baseurl. "/img/" . $model->image. "'>" .
"<div class='caption'>
<h3 style='text-align: center'>" . $model->ngo_name ."</h3>
<a href='ngo-profile.php'> <button class='btn btn-primary center-block'>View Profile</button></a>
</div></div></div>";
if ($cnt%$nThumbXRow == 0){
echo "</div><!-- row ending here -->";
}
$cnt++;
}
?>
</div><!--ngo-content ending here-->
答案 0 :(得分:1)
试试这种方式
public function actionAllngo()
{
$allmodels= Ngo::model()->findAll(array('order'=>'id DESC'));
$this->layout='main';
$this->render('allngo',array('allmodels'=>$allmodels));
}
