Simple SEO URL (OLD version) [support thread]

I think you are in the wrong support thread, this thread is not for ultimate seo url.

I want to know if we are all okie with the current link structure, it will be hard to change things later:

http://demo.rubikintegration.com/zencart/

Otherwise we will stick with it.

I like yourr suggestion in post #37. The link above does not seem to be using the shorter version at this point.

Check again, see if you like something like this:

:clap: Great work yellow1912! :clap:

I am posting three changes in case they could be of any help:

1. I changed .htaccess to avoid passing the variable MR which is failing on some servers:

Code:

---

#### BOF SSU
RewriteEngine On
RewriteBase /site/

# Deny access from .htaccess
RewriteRule ^\.htaccess$ - [F]

# Existing files shouldn't get rewritten
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f

# The rest can go to ZC
RewriteRule ^(.+) index.php/$1 [E=VAR1:$1,QSA,L]
#### EOF SSU

---

2. I changed the URL parsing function so it can handle whatever file extension that the user sets. In init_ssu.php:

PHP Code:

---

function parse_url($debug=false){
    $link = $_SERVER['REQUEST_URI'];

    // taking care of the shop catalog
    $catalog_dir = (isset($_SERVER['HTTPS']) || $_SERVER['SERVER_PORT']==443) ? DIR_WS_HTTPS_CATALOG : DIR_WS_CATALOG;
    $link = str_replace($catalog_dir, '' , $link);

    // taking care of file extension
    $link = str_replace('.'.SSU_FILE_EXTENSION, '' , $link);

    // taking care of parameters
    $mr_parts = explode('/', current(explode('?', $link)));
    $mr_parts_count = count($mr_parts);
            
    // first element is always main_page
    // even if this is a "static" page, assigning first element to 
    $_GET['main_page'] = $mr_parts[0];
    for($i= 1; $i < $mr_parts_count; $i = $i + 2){
        if(isset($mr_parts[($i + 1)])){
            $_GET[$mr_parts[$i]] = $mr_parts[($i + 1)];
        }
        else{
        $_GET[$mr_parts[$i]] = '';
        }
    }
    unset($mr_parts, $mr_parts_count);
        
    // taking care of product and category name
    if(isset($_GET['products_id'])){
        $products_id = explode(SSU_ID_DELIMITER,$_GET['products_id']);
        $_GET['products_id'] = $products_id[count($products_id)-1];
    }
    if(isset($_GET['cPath'])){
        $cPath = explode('-',$_GET['cPath']);
        $_GET['cPath'] = $cPath[count($cPath)-1];
    }

    if($debug)
        print_r($_GET);
}

3. Finally, the category three was not preserved (for example, clicking a top category would open its sub-category tree, but clicking on a sub-category would close the whole tree). In init_ssu.php:

PHP Code:

---

    function get_category_name($cPath){
        global $db;
        if(empty($cPath)) return '';
        $category_id = explode('_',$cPath);
        $category_id = $category_id[count($category_id)-1];
        
        $file_name = $this->build_category_filename($category_id);
        if(($content = file_get_contents($this->cache_folder.$file_name)) !== false)
            return $content;    

        return $this->set_category_name($cPath, $category_id);
    }
    
    function set_category_name($cPath, $category_id){
        $file_name = $this->build_category_filename($cPath);
        $sql_query = 'SELECT categories_name FROM '.TABLE_CATEGORIES_DESCRIPTION.' WHERE categories_id ='.$category_id.' LIMIT 1';
        return $this->_get_name($file_name,$sql_query,'categories_name',$cPath);
    }
    
    function build_category_filename($category_id){
         return "c$category_id";
    }

You are right, I made some stupid changes and didnt keep the category tree, will fix that.

As for part 2, that's better than having to change the htaccess file, good job :laugh:

New version updated to make changes suggested by skaimauve.

@skaimauve: we cant use str_replace to replace the catalog_dir because is is possible that somewhere in the url contains a string that is exactly the same with catalog_dir and will be replaced as well.

I used preg_replace to limit the replacement to 1 only.


Next update will cover:
1. ezpage link is not created the way it should be, will fix that
2. Allow store owner to stack more than 1 category names into the links, and allow store owner to limit the number of category names on the links as well.

Oups... :wink:

:clap: Good work on the update code yellow1912! :clap:

Wow , we have a winner. This feature is nicely implemeted!

How about creating links on this format?

Again, if this is of any help. In init_ssu.php:

1. Change what is inside the loop:

PHP Code:

---

    function parse_url($debug=false){
        global $request_type;
        // attempt to check current protocol being used
        // This check is not perfect, but should work most of the time
        if ($request_type == 'SSL') 
            $catalog_dir = DIR_WS_CATALOG;
        else
            $catalog_dir = DIR_WS_HTTPS_CATALOG;
        $extension = trim(SSU_FILE_EXTENSION);
        // we want to remove $catalog_dir and 
        $mr_parts = explode('/', trim(current(explode('?', ($catalog_dir=='/' && empty($extension)) ? getenv('REQUEST_URI') : preg_replace(array($catalog_dir,'/\.'.$extension.'/'),'',getenv('REQUEST_URI'), 1))), '/'));
        $mr_parts_count = count($mr_parts);
        // first element is always main_page
        // even if this is a "static" page, assigning first element to 
        $_GET['main_page'] = $mr_parts[0];
        for($i= 1; $i < $mr_parts_count; $i++){
>            $file_name = current(explode(SSU_ID_DELIMITER, $mr_parts[$i],2));
            // TODO: an more efficient way to do this?
>            if($file_name[0] == 'c') {
>              if(file_get_contents($this->cache_folder.$file_name) !== false)
>                    $_GET['cPath'] = substr($file_name,1);                     
            }
>            elseif($file_name[0] == 'p') {
>              if(file_get_contents($this->cache_folder.$file_name) !== false)
>                    $_GET['products_id'] = substr($file_name,1);                     
            }
            elseif(isset($mr_parts[($i + 1)])){
                $_GET[$mr_parts[$i]] = $mr_parts[($i + 1)];
                $i++;
            }
            else{
                $_GET[$mr_parts[$i]] = '';
                $i++;
            }
        }
        unset($mr_parts, $mr_parts_count);
        if($debug)
            print_r($_GET);
    }

And two lines here

PHP Code:

---

        // Appending category name and product name into the link
        if(strstr($parameters,'cPath')!==false || strstr($parameters,'products_id')!==false || $page ==''){
            $parameters = explode('/',$parameters);
            
            for($i=0; $i < count($parameters); $i++){
                if($parameters[$i]=='cPath'){
>                    $parameters[$i] = 'c'.$this->get_category_name($parameters[$i+1]);
                    unset($parameters[$i+1]);
                }
                elseif($parameters[$i]=='products_id'){
>                    $parameters[$i] = 'p'.$this->get_product_name($parameters[$i+1]);
                    unset($parameters[$i+1]);
                }
                elseif($parameters[$i]=='main_page'){
                    $page = $parameters[$i+1];
                    unset($parameters[$i]);
                    unset($parameters[$i+1]);
                }
            }
            //print_r($parameters);
            $this->array_clean_up($parameters);
            $parameters = implode('/',$parameters);
        }

And one line here:

PHP Code:

---

    function _get_name($file_name, $sql_query, $field_name, $original_value){
        global $db;
        $result = $original_value;

        if($sql_result->RecordCount() > 0){
            // remove non alphanumeric
            $result = preg_replace("/[^a-zA-Z0-9s]/", SSU_NAME_DELIMITER, $sql_result->fields[$field_name]);
            // remove excess underscore
            $result = preg_replace('/'.SSU_NAME_DELIMITER.SSU_NAME_DELIMITER.'+/', SSU_NAME_DELIMITER, $result);
