opencart 1.5 how to add module in a header

Question

Please some one tell me how can I position modules like slider or banner in header or how can we define additional regions for the modules.

Answer 1

You can learn from controller/common/column_right.php

Check module position (line 50), you can adapt it to "header":

$module['position'] == 'column_right'

Set the output (line 69), you can adapt it to something like "header_mod" :

$this->data['modules']

You need to modificate module at admin to show additional module position.
There is no "header" module position options at admin page.
