Almost have easy urls working..

[sitefire]

I have been playing with a contrib called easy seo urls and have got it working, along with creating a correct .htaccess but need to add the capability of adding one more category as our site has 1 main category, 1 sub category and 1 sub sub category for our products.

The contrib now only allows for 2 categories.

 

Once everything is up and running I will post the completed contrib with the .htaccess file for an apache server.

 

Here is a sample of the code:

function URL_rewrite($url) {
$matches = array();
if(preg_match("/cPath=([0-9]+)_?([0-9]+)?(&products_id=)?([0-9]+)?/", $url, $matches)>0 && preg_match("/action=/", $url)==0)
{
	// fetch category name
	if(isset($matches[1]))
	{
		$cat_id = $matches[1];
		$cat_query = tep_db_query("select categories_id, categories_name from " . TABLE_CATEGORIES_DESCRIPTION . " where categories_id = '" . (int)$cat_id . "' limit 1");
		$cat_string = tep_db_fetch_array($cat_query);
		$cat_string = URL_safe($cat_string['categories_name']);
	}
	// fetch subcategory name
	if(isset($matches[2]))
	{
		$subcat_id = $matches[2];
		$cat_query = tep_db_query("select categories_id, categories_name from " . TABLE_CATEGORIES_DESCRIPTION . " where categories_id = '" . (int)$subcat_id . "' limit 1");
		$subcat_string = tep_db_fetch_array($cat_query);
		$subcat_string = URL_safe($subcat_string['categories_name']);
	}
	// fetch product name
	if(isset($matches[4]))
	{
		$prod_id = $matches[4];
		$prod_query = tep_db_query("select products_name, products_id from " . TABLE_PRODUCTS_DESCRIPTION . " where products_id = '" . (int)$prod_id . "' limit 1");
		$prod_string = tep_db_fetch_array($prod_query);
		$prod_string = URL_safe($prod_string['products_name']);			
	}

	// get rid of the index page in URL
	if(preg_match("/(.*)index\.php/", $url)>0)
	{
		$url = preg_replace("/index\.php.*/", "", $url);
	}

	// get rid of the products page in URL
	if(preg_match("/(.*)product_info\.php/", $url)>0)
	{
		$url = preg_replace("/product_info\.php.*/", "", $url);
	}

	// build new URL
	if(isset($cat_string) && $cat_string != "")
	{
		$url .= $cat_string."-c".$cat_id;

		// append subcat string
		if(isset($subcat_string) && $subcat_string != "")
		{
			$url .= "/".$subcat_string."-s".$subcat_id;
		}

		// append product title
		if(isset($prod_string) && $prod_string != "")
		{
			$url .= "/".$prod_string."-p".$prod_id;
		}			
	}

   	return $url."/";
}
else
{
	return $url;
}
}

// Make categories and product titles safe for URLs
function URL_safe($str) {
$str = strtolower($str);
$str = preg_replace("/[^a-z0-9\-]+/i","-",$str);
$str = urlencode($str);
return $str;
}
