404 error in codeigniter pagination - php

Question

I see a lot of this question, but I couldn't solve the issue.
I suspecting that it doesn't read the right segment as I have a reroute config and htaccess to remove the index page.
The code is throwing a 404 page.
Here is my Model:
public function get_city_reviews($city_id,$limit,$offset) {
$list = array();
$this->db->from('biz');
$this->db->where('city_id',$city_id);
$this->db->order_by('created_at','desc');
$this->db->limit($limit,$offset);
$query = $this->db->get();
foreach($query->result() as $row) {
$list[] = $row;
}
return $list;
}
My Controller:
$slug = $this->uri->segment(1,'');
if($slug)
{
$this->load->model('catsAndCities','cc');
$this->cc->set_table_name('city');
$city = $this->cc->get($slug,'slug');
if(!$city || $city->parent_id != 0)
{
show_404();
}
else
{
$this->tank_auth->set_user_city($city);
}
}
else
{
$city = $this->tank_auth->get_user_city();
}
$this->load->library('pagination');
$config = array();
$base_url ="local/index/";
$config["base_url"] = site_url().$base_url;
$config["total_rows"] = $this->bizs->record_count();
$config["per_page"] = 5;
$config["uri_segment"] = 4;
$config['full_tag_open'] = '<p class="pageBar">';
$config['full_tag_close'] = '</p>';
$config['num_links'] =2;
$config['anchor_class'] = 'class="page-num" ';
$this->pagination->initialize($config);
$page = ($this->uri->segment(4)) ? $this->uri->segment(4) : 0;
$data["results"] = $this->bizs->get_city_reviews($city->id,$config["per_page"],
$page);
$data["pagination_links"] = $this->pagination->create_links();
$data['reviews'] = $data["results"];
$this->load->view('local/index',$data);
My View:
<div id="pagination-container">
<div class="pagination">
<ul>
<?=$pagination_links?>
</ul>
</div>
This is my Routes:
$route['default_controller'] = "local/city";
$route['[0-9a-zA-Z\-_]+'] = "local/city";
$route['scaffolding_trigger'] = "";
This is my htaccess:
<IfModule mod_rewrite.c>
RewriteEngine On
#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,
#previously this would not have been possible.
#'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php/$1 [L]
#Checks to see if the user is attempting to access a valid file,
#such as an image or css document, if this isn't true it sends the
#request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
ErrorDocument 404 /index.php
</IfModule>

Answer 1

As i suspected, you are telling CI to find 404 page if no city is found. Try commenting this : Or find a way to work around it.
if(!$city || $city->parent_id != 0)
{
show_404();
}
else
{
$this->tank_auth->set_user_city($city);
}
Then change
$base_url ="local/index/";
to
$base_url ="";
And your segment to 1
$config["uri_segment"] = 1;
That should do it.

Answer 2

Try changing the base_url to "local/city", and the uri_segment changed to 3.
