我是yiibie，我在显示数据时遇到问题，我想在界面上显示数据。我已从ngo image检索到ngo name和ngo table，但图片以长垂直线显示，而我想在每行显示4个非图像。我在控制器中创建了一个Allngo()来获取ngo table中的所有数据和视图中的allstory.php文件以显示数据。这是NgoController的代码。

Please help me in doing this, th
ank you。
答案 0 :(得分：1)
尝试更改与此行相关的代码部分
<?php
$cnt= 0;
$nThumbXRow = 4;
foreach($allmodels as $model) {
if (cnt%$nThumbXRow == 0){
echo "<div class='row'>";
}
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++;
}
?>
然后按顺序改变你的行动
public function actionAllngo()
{
$allmodels= Ngo::model()->findAll(array('order'=>'id DESC'));
$this->layout='main';
$this->render('allngo',array('allmodels'=>$allmodels));
}
