Question

您好，iam是joomla的创建模块mod_testimonial的新手。 我已经将数据放入$rows = $db->loadObjectList(); 从帮助文件中

和回声后$ rows中的数据是

Array
(
    [0] => stdClass Object
        (
            [name] => james
            [testimonial] => Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s,
            [regdate] => 2013-12-31 13:24:29
            [id] => 37
        )

    [1] => stdClass Object
        (
            [name] => Tom
            [testimonial] => Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.
            [regdate] => 2013-12-31 14:45:56
            [id] => 38
        )

    [2] => stdClass Object
        (
            [name] => Alyson
            [testimonial] => is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s
            [regdate] => 2014-01-03 14:52:09
            [id] => 42
        )

)

在我的default.php文件中，我已经像这样从数组中获取了数据。

 <p><?php print_r($rows[0]->testimonial);?><span class="testimonial-by"> —<?php print_r($rows[0]->name);?>,<?php echo date('M Y',strtotime($rows[1]->regdate)); ?>,</span></p>



  <p><?php print_r($rows[1]->testimonial);?><span class="testimonial-by">—<?php print_r($rows[1]->name);?>,<?php echo date('M Y',strtotime($rows[2]->regdate)); ?>,</span></p>



<p><?php print_r($rows[2]->testimonial);?><span class="testimonial-by">—<?php print_r($rows[2]->name);?>,<?php echo date('M Y',strtotime($rows[0]->regdate)); ?>,</span></p>

我的助手文件是

static function getRecord($params)
    {

        $db = JFactory::getDBO();
        $query = "SELECT name,testimonial,regdate,id FROM #__testimonial WHERE published = '1' AND featured='1' ";
        $db->setQuery( $query);
        $rows = $db->loadObjectList();
        return $rows;
    }

。直到这里一切正常，但是如果我将后端的数据取消发布或取消功能，将引发如下错误

Notice: Undefined offset: 2 in modules\mod_testimonial\tmpl\default.php on line 37

Notice: Trying to get property of non-object in modules\mod_testimonial\tmpl\default.php on line 37
File not found

我知道这是因为没有

offset [2] => stdClass Object
        (
            [name] => Alyson
            [testimonial] => is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s
            [regdate] => 2014-01-03 14:52:09
            [id] => 42
        )

我想给出一个适当的循环，以便跳过此问题，并且我不需要更改模板。

请帮助我，非常沮丧地尝试了所有的东西。 谢谢

尝试这个，

在您的帮助文件中。

function getRecord($params)
    {

        $db = JFactory::getDBO();
        $query = "SELECT name,testimonial,regdate,id FROM #__testimonial WHERE published = '1' AND featured='1' ";
        $db->setQuery( $query);
        return $db->loadObjectList();

    }

在您的模块文件mod_testimonial.php有类似

$data = helperClassname :: getRecord($param);

在您的default.php有类似的内容。

if(sizeof($data) > 0){

foreach($data as $key=>$value){

echo "<br/>Name".$value->name;
}

}
