Trying to get property of non-object in Codeigniter? - php

Question

My controller code just generate ten copies of the same data. And I put the data in an array of array.Controller Code Below:
for($i=0;$i < $this->per_page;$i++)
{
$temp['title'] = "test";
$temp['link'] = "localhost/cib/index.php";
$temp['month'] = '4';
$temp['day'] = '21';
$temp['authorlink'] = "localhost/cib/index.php/author";
$temp['author'] = "Charles";
$temp['content'] = "tetestersafaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
$results[] = $temp;
}
$data['main_content'] = 'report_list';
$data['posts'] = $results;
$this->load->view('include/templates', $data);
And I show the data generated by controller in the view page report_list, the code of report_list is
<div id="bg_top">
</div>
<div class = "container" id="content">
<div class="row-fluid">
<div class="span9" id="content_left">
<h2>解题报告列表</h2>
<link href="<?php echo base_url('assets/css/style.css') ?>" rel="stylesheet">
<?php if(!empty($posts) && is_array($posts)):?>
<?php foreach($posts as $post):?>
<div class="entry">
<h2 class="entrytitle"><?php echo anchor($post->link, $post->title)?><span></span></h2>
<div class="entrymeta1">
<div class="meta-date">
<span class="meta-month"><?php echo $post->month?></span>
<span class="meta-day"><?php echo $post->day?></span>
</div>
<span class="meta-author"><?php echo anchor($post->authorlink, $post->author)?></span>
<span class="meta-category"></span>
<span class="meta-comment"></span>
<div class="clear"></div>
</div><!-- [entrymeta1] -->
<div class="entrybody">
<p><?php echo $post->content;?><?php echo anchor($post->link, '阅读全文')?></p>
</div>
<div class="entrymeta3">
</div>
</div><!-- [entry] -->
<?php endforeach;?>
<?php endif;?>
</div>
<div class="span3">
<?php echo "hello world2";?>
</div>
</div>
</div>
The question is where am wrong? why is there errors "Trying to get property of non-object"?
I tried to print the data in the controller, it works quite well.
foreach($results as $post)
{
foreach($post as $key=>$value)
{
echo $key.':'.$value;
echo '<br/>';
}
}

Answer 1

You need to print the variables in the view file in array style like this:
<?php echo anchor($post['link'], $post['title'])?>
Still you can always print the array to view the structure:
<?php echo "<pre>";print_r($posts);echo "</pre>";

Answer 2

My assumption is that
You are expecting $posts as array of objects. But in $posts in some loaction there is no object with property month, day etc. So just before the for loop you should look the type of $posts by
var_dump($posts)
This will give you the clear picture about your error

Answer 3

Change all the variables $post->link to array $post['link']
$post->month
$post->day
every fields that are using in template.
