I have a problem with routing in CI.
I have a controller with parameters that supports categories and subcategories
category$1/subcategory$2
I came up with such entries, but they do not quite work.
Code:
$route['(:any)'] = 'ads/cat/$1';
$route['(:any)/(:any)'] = 'ads/cat/$1/$2';
$route['(:any)/(:any)/(:num)'] = 'ads/cat/$1/$2/$3';
Everything works with pagination in subcategories category/subcategory/2, category/subcategory/3, etc.
But in category it's going like category/2, category/2/3, category/2/4, category/2/5 etc.
Code:
public function cat( $cat_alias = null, $subcat_alias = null)
{
$this->load->library('pagination');
$limit = 20 ;
if (!empty($subcat_alias) && !ctype_digit((string)$subcat_alias) )
{
$start = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
}
else
{
$start = ($this->uri->segment(2)) ? $this->uri->segment(2) : 0;
}
echo $start;
echo '<br>';
if (isset($_GET['miasto'])) {
$city = $_GET['miasto'];
}
$where = array( 'catalogue' => $cat_alias );
$ad_category = $this->Site_model->get_single( 'categories' , $where );
$children = $this->Site_model->get_childrens($ad_category->id);
foreach ($children as $child)
{
$childs[] = $child->id;
}
if ( !empty( $ad_category ) )
{
if (!empty($subcat_alias) && !ctype_digit((string)$subcat_alias))
{
$where = array( 'catalogue' => $subcat_alias );
$ad_category2 = $this->Site_model->get_single( 'categories' , $where );
$title = $ad_category2->title;
$newtitle = str_replace('{miasto}', (!empty($city)) ? $city : 'Warszawa', $title);
$description = $ad_category2->description;
$newdescription = str_replace('{miasto}', (!empty($city)) ? $city : 'Warszawa', $title);
$data['meta']['title'] = $newtitle;
$data['meta']['desc'] = $newdescription;
