how to like value to %field_value% in sql or codeigniter? - sql

Question

I have a table named uri_table that contain:
id, uri_segment
1, /dir_name/bla-bla-1/
2, /dir_name/bla-bla-2/
3, /dir_name/bla-bla-3/
I want to get the pure link that only contain until controller_name and the controller param are not included. but when I use $_SERVER['URI_SEGMENT'] it will get the controller param too.
so I can't do this code below to search in my model:
function check_uri()
{
$this->db->like('uri_segment',$uri_segment,'after');
$id = $this->db->get('uri_table')->row_array()['id'];
return $id;
}
instead of:
function check_uri($request_uri=$_SERVER['URI_SEGMENT'])
{
//trim controller param that is numeric
for($i = strlen($request_uri)-1;$i > 0;$i--)
{
if(is_numeric($request_uri[$i]) || $request_uri[$i]=='/')
{
continue;
}
else
{
$request_uri = substr($request_uri,0,$i+1);
break;
}
}
$this->db->where('uri_segment',$request_uri);
$id = $this->db->get('uri_table')->row_array()['id'];
return $id;
}
This is my code right now but is also can remove param that is number if the $request_uri = '/dir_name/bla-bla-3/1/some_param/3' it'll return $id null. What can I do to remove the param/get uri without controller param or how to compare the $uri_segment to uri_segment ($this->db->like($uri_segment, '%uri_segment%'))?

Do one thing when you create a controller in that store the controller name like this:
class About extends CI_Controller {
// MVC config
var $PANEL = '';
var $CONTROLLER = 'about';
var $MODEL = 'mdl_about';
var $TITLE = 'page title';
var $LIST_PAGE_NAME = 'aboutus';
function About() {
parent::__construct();
//$this->load->model($this->MODEL, 'model');
}
function index() {
$this->load->view($this->LIST_PAGE_NAME);
}
}
So that above controller, model, page title and view page can be use anywhere is related to that controller.
To display the variable value use like this:
echo $this->CONTROLLER;
Or you can try this:
$this->router->fetch_class(); //for controller
$this->router->fetch_method(); //for method
