Codeigniter route page using value fetch from database - codeigniter

Question

currently I have a page like the following -
abc.com/controller/action/23
Here 23 is Item id,which is dynamic. I have to fetch the name of the item using the id from database and route to a new url like following -
abc.com/controller/p/23-itemname.
How can I do that?

Answer 1

what you can do is when the user visits this page:
abc.com/controller/action/23
You put this code into the controller
CONTROLLER
function action()
{
$id = $this->uri->segment(3); //id is now 23, this is the third uri
$data['details'] = $this->YOUR_MODEL->get_details($id);
foreach($data['details'] as $d)
{
$itemname = $d->YOUR_TABLE_COLUMN_NAME;
}
redirect(base_url(). 'controller/p/' . $id . '-' . $itemname);
//line produces abc.com/controller/p/23-itemname
}
MODEL
function get_details($id)
{
$this->db->select('*');
$this->db->from('YOUR_TABLE_NAME');
$this->db->where('YOUR_ID_COLUMN_NAME',$id);
$query = $this->db->get();
return $query->result();
}
Just comment if you need more clarifications.
Goodluck meyt
EDIT
Since you have action and you redirect to function p, here is what will happen.
function p()
{
$explodethis = $this->uri->segment(3); //Contains "23-itemname"
$pieces = explode("-", $explodethis); //Separate by the dash
$id = $pieces[0]; //Contains "23"
$itemname = $pieces[1]; //Contains "itemname"
$data['details'] = $this->YOUR_MODEL->YOUR_FUNCTION(YOUR_PARAMETERS)
$this->load->view('YOUR_VIEW',$data);
}

Routing not required to do this. You may generate link by item name
<a href="<?php echo site_url('controller/action').'/'.$val['item_id'].'-'.$val['item_name']; ?>"
and now in controller explode this title to get ID of the item and then execute your query
$title = explode('-','23-item-name');
$id = trim($title[0]);//this is your item ID
