Question

我有一个 table 名称 Business 具有属性 business_name,business_id,business_description,image。现在我想在我的着陆页中显示 4 个最近添加的业务？我怎样才能实现这个目标

这是我在 main.php 中的代码，我希望它是动态的。

最近添加的部分是我想要最近添加的业务的地方。

Answer 1

如果 business_id 是主要的或自动递增的，你可以使用这个：

$bussiness = Bussiness::model()->findAll(array('order'=>'business_id ', 'limit'=>'1'));

对于 select 4 行：

 $bussiness = Bussiness::model()->findAll(array('order'=>'business_id ', 'limit'=>'4'));

Answer 2

首先，您必须使用 gii 为您的 table 生成模型。 Read more here

一旦你有了模型，你就可以通过使用从数据库中提取所有记录

Business::model()->findAll()

业务是gii生成的模型名称。

下面的代码显示了如何显示所有 business_names.

$businesses = Business::model()->findAll();
  foreach($businesses as $business)
   echo $business->business_name;

希望您能弄清楚您的代码应该是什么样子:)

Answer 3

<?php 
$criteria = new CDbCriteria(array('order'=>'id DESC','limit'=>4));
$model = Business::model()->findAll($criteria);
$names=array();
$image=array();
foreach ($model as $list) {

//    echo ($list->business_name);
//                echo ($list->image);
          $names[] = $list->business_name;
          $image[] = $list->image;
                }  
                $a=0;
                $b=1;
                $v=2;
                $d=3;
for($i=0;$i<1;$i++){
    $one=$names[$a];
     $two=$names[$b];
     $three=$names[$v];
     $four=$names[$d];
      $oneimage=$image[$a];
     $twoimage=$image[$b];
     $threeimage=$image[$v];
     $fourimage=$image[$d];

}
 echo $one;
    echo $two;
    echo $three;
   echo $four;
    echo $oneimage;
    echo $twoimage;
    echo $threeimage;
   echo $fourimage;
?>

这是我的 index.php 从业务模型中获取数据，例如数组并将每个值存储在一个变量中然后我想显示变量值的任何地方我只是回显它，就在这里..
