joomsef mod_rewrite 15 years, 11 months ago #9510

I'm using joomla artio SEF component on my server, and I needed to create dynamic SEF urls so I used mod_rewrite and wrote something like:

RewriteCond %{REQUEST_URI} ^/mm/.*?/.*?$
RewriteRule ^mm/(.*?)/(.*?)$ index.php?option=com_mindmapufp&view=mindmapufp&name=$2&id=$1&tmpl=component [L]

This will do an internal redirection from an url like /mm/something/something to index.php?option=com_mindmapufp&view=mindmapufp&name=something&id=something&tmpl=component

After debugging, the GET variable "option" gets changed to "com_content" instead of "com_mindmapufp", so I get a 404 error! If I disable joomsef plugin, it works fine...

Any ideas on how to solve it?

Thanks!

jaku	Hello, that is a bit strange. Anyway, make sure that JoomSEF handler for com_mindmapufp is set to "skip".

I debugged the problem and it turns out that when internal redirecting a page through mod_rewrite, QUERY_STRING is updated but REQUEST_URI stays like the old url.

To hotfix the problem I changed components/com_sef/joomsef.php:

 
    function parse(&$uri)
    {
        global $mainframe;
 
        // test for the backlink plugin to work correctly
        if (JPluginHelper::isEnabled('system', 'backlink')) { 
            $joomlaRequest = $_SERVER['REQUEST_URI'];
            $realRequest = $uri->toString(array('path', 'query'));
 
            if ($realRequest != $joomlaRequest) {
                $uri = new JURI($joomlaRequest);
            }
        }
 
+       if (!empty($_SERVER['QUERY_STRING']))
+       {
+               $uri->_query .= (!empty($uri->_query) ? '&' : '').$_SERVER['QUERY_STRING'];
+       }

Probably the redirect detection should be made prior to this function and in other parts of the code, but this just worked for me. How can I suggest this to enter the mainstream as a mod_rewrite compatibility fix?

Thanks.
