foreach() return a null value - php

Question

I have another error anymore, when I try to display a result in my view, the result is NULL and I can't see the result of my query at models.
Here's my code list :
on the controller (home.php) :
$data['hasil5'] = $this->home_model->popular_list();
on the model (home_model.php) function popular_list() :
function popular_list($limit=2)
{
$this->db->select('news.*');
$this->db->where('id',$this->uri->segment(3));
$this->db->where('publish',1);
$this->db->where('viewed >= ',5);
$this->db->order_by('id','DESC');
$this->db->limit($limit);
$query = $this->db->get('news');
return $query->result();
} //thanks to kumar_v
and on my view (home.php) as a part of "Popular news" :
<h2>Most Popular News :</h2>
<?php
foreach ($hasil5 as $data5):
?>
<div class="welcome clear"><img class="imgl" src="<?php echo base_url(); ?>assets/news/original/<?php echo $data5->image; ?>" alt="" height="119" width="125" />
<div class="fl_right">
<h2><?php echo anchor($data5->kategori.'/detail/'.$data5->id,$data5->title) ?></h2>
<p><?php echo $data5->sinopsis; ?></p>
</div>
</div>
<?php
endforeach;
?>
The results is NULL, can you correct it again? thanks..

Answer 1

try this :
function popular_list($limit = 2) {
$query = $this->db->select('*')
->where('id',$this->uri->segment(3))
->where('publish',1)
->where('viewed >= ',5)
->order_by('id','DESC')
->limit($limit)
->get('news');
print_r($query->result());
return $query->result();
}
You can put the whole thing in $query variable. And also, you can improve your $this->db->where() by putting the params in an array.

Answer 2

You should fix your code to look like so:
<?php
foreach ($data['hasil5'] as $data5):
?>
You were using the wrong variable in your foreach loop.

Answer 3

Checking if the query will return any row is a good idea.
function popular_list($limit=2)
{
$result = null;
$this->db->select('news.*');
$this->db->where('id',$this->uri->segment(3));
$this->db->where('publish',1);
$this->db->where('viewed >= ',5);
$this->db->order_by('id','DESC');
$this->db->limit($limit);
$query = $this->db->get('news');
if($query->num_rows() > 0)
{
$result = $query->result();
}
return $result;
}
