Codeigniter and database issues - php

Question

Right im new to this and a little out of my depth. Ok so I'm trying to bring in some data and im getting some errors and am I a little confused as to whats going on.
here is the model code:
public function get_webstore_sets($limit, $offset) {
$this->db->select("*");
$this->db->from('st_posts');
$this->db->where("type", "webstore");
$this->db->limit($limit, $offset);
$this->db->order_by('created', 'DESC');
$query = $this->db->get();
$data = $query->result_array();
return$data;
}
public function count_webstore_sets() {
$this->db->select("*");
$this->db->from('st_posts');
$this->db->where("type", "webstore");
$this->db->order_by('created', 'DESC');
$query = $this->db->get();
$count = $query->num_rows();
return $count;
}
and here is what im trying in the controller:
class Webstore extends MY_Controller {
public function __construct() {
parent::__construct();
$this->load->model("post");
$this->load->database();
$this->load->helper("url");
}
public function index() {
$this->data['posts'] = $this->post->get_webstore_sets($limit=null, $offset=null); // calling Post model method getPosts()
$data = array('page_title' => 'Store', 'video_content');
$this->layout("pages/webstore", $data);
}
}
and then bringing it in on HTML:
<?php foreach ($posts as $webstore): ?>
<div class="col-md-12" style="height: 225px;">
<div class="col-md-3">
<?php
$webstore['images'] = explode(".", $webstore['images']);
?>
<img class="thumbnail" width="250px" src="<?php echo $video['images'][1]; ?>.gif"/>
</div>
<div class="col-md-5">
<h3><?php echo $webstore['title']; ?></h3>
</div>
<div class="col-md-4 text-center">
Date Added: <?php echo date('d-m-y', strtotime($webstore['created'])) ?>

<?php endforeach; ?>
I know the connection is ok as the site is bringing in data from else where.
and this is the error im getting :
Severity: Notice
Message: Undefined variable: posts
Filename: pages/webstore.php
Line Number: 39
A PHP Error was encountered
Severity: Warning
Message: Invalid argument supplied for foreach()
Filename: pages/webstore.php
Line Number: 39
I have blanked out the file path just in case ;) Edited for the above errors

Answer 1

In this code:
public function index()
{
$this->data['posts'] = $this->post->get_webstore_sets($limit=null, $offset=null); // calling Post model method getPosts()
$data = array('page_title' => 'Store', 'video_content');
$this->layout("pages/webstore", $data);
}
you are passing $data array to view, but not $this->data one. Also, 'video_content' element of $data array should have it's key to let you to approach to it in view. Or it is key itself missing value?
Change it to:
public function index() {
$this->data['posts'] = $this->post->get_webstore_sets($limit=null, $offset=null); // calling Post model method getPosts()
$this->data['page_title'] = 'Store';
$this->layout("pages/webstore", $this->data);
}
Now, you should be able to get $posts variable in view file. Just check what you have to do with value/key 'video_content'.

Answer 2

You are calling get_webstore_sets() without a parameter, so either fill in some parameters (limit, offset) or define the function as follows:
public function get_webstore_sets($limit=null, $offset=null) ...
I would suggest giving the parameter though in the function index() of class Webstore.
