Question

Hello iam是joomla的新手，创建了一个模块mod_testimonial。我已将数据从帮助文件

放入$rows = $db->loadObjectList();

和echo之后$行中的数据是

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>

我的帮助文件是

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;
    }

。在这里确定一切都好，但是如果我要从后端取消发布或取消数据，则会产生这样的错误

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
        )

我想提供一个正确的循环，以便此问题跳过，我不需要更改我的模板。

请非常沮丧地帮助我尝试所有的东西。谢谢你

试试这个，

在您的帮助文件上。

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_testimonial.php中有类似

的内容

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

在你的default.php上有类似的内容。

if(sizeof($data) > 0){

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

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

}

希望它的帮助..
