Question

I want to modify a native joomla module that display articles of a category. I want it to display articles of an other prefix tables (both joomla website are on the same server).

Notice that I already looked at available extension but none of them would fit.

I tried to modify the helper.php of the native joomla module
tables, by changing the

$com_path =
but i am getting aFatal error.

Native code:
$com_path = JPATH_SITE.'/components/com_content/';

My try :
$com_path = '/homez.420/kmxsiksf/rsc/components/com_content/helpers/route.php

To use an external database (even if it’s on your server) in Joomla extensions, the proper way would be to set some options before retrieving the JDatabase-object.

Create a helperclass to handle your external db, and in every method that uses the DB-object you simply set the options of your external db before retrieving the object:

$option = array(); 
$option['driver']   = 'mysql';
$option['host']     = 'localhost';    // In your case probably localhost 
$option['user']     = 'dbusername';       // User for database authentication $option['password'] = 'badpass12345';   // Password for database authentication $option['database'] = 'bigdatabase';      // Database name 
$option['prefix']   = 'abc_';             // Database prefix (may be empty)  
$db = & JDatabase::getInstance( $option );

You are now able to use your external database the same way as you would with your regular db.
