For one of my recent Joomla project, I used the Joomshopping component as the Shopping Cart solution. While developing the site, I found some issues with template overriding in Joomla 1.6 and I had a hard time with it. After a long sleepless night I found a solution or hack :) to solve that issue. I had problem with the com_user component template, so I did this trick and it worked. Please note that this is a hack if you know any better method than this please let me know.

1. Open includes directory from the joomla core installation folder.
2. open application.php file
3. goto line number 470 and add the following code under the commented statement.

if(JRequest::getVar('controller') == 'your controller name' || JRequest::getVar('option')=='your component name')

{
            $template->template = 'your template name';

}

5. Save the file and refresh the site after clearing the cache. Hope it will help someone :)

For one of my recent drupal project I had faced some issue with the Ajax request. I was trying to change the fields in a view, but unfortunately drupal showed me an error "An AJAX HTTP request terminated abnormally". It might prevent you also from creating views or adding fields etc. etc. Basically it happens when the drupal core unable to determine the base_url. By specifying the base_url in drupal's settings.php file, we can resolve this issue. Here we go.

1. Open /sites/default/settings.php in your favourite text editor.
2. Find this line # $base_url = 'http://www.example.com';
3. Add the absolute url of your domain in place of example.com.
4. Save the file.
5. Clear drupal cache, and try again. It will work smoothly.
