你好，我是joomla的新手，创建模块mod_推荐。我已经将数据放入

$rows=$db->loadObjectList（）中从帮助文件

echo后面的$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default.php文件中，我从数组中获取了如下数据

 <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>

.到目前为止一切正常，但如果我取消发布或取消后端数据的特征，将引发类似这样的错误

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，以便跳过这个问题，并且不需要更改我的模板

请帮我把所有的东西都试过了。
谢谢你试试这个

在助手文件上

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_estimational.php
中

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

在您的
default.php
上有如下内容

if(sizeof($data) > 0){

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

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

}

if（sizeof（$data）>0）{
foreach（$key=>$value形式的数据）{
回显“
名称”。$value->Name；
}
}

希望对您有所帮助。
检查数组是否有值，然后仅访问其索引值是的，谢谢，但是如何在循环中获取该数组，使其获得连续性并显示可用的数据。我已经尝试了for each循环，但没有更改，完全空白，请帮助我解决。可能重复的
if(sizeof($data) > 0){

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

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

}
