Editing wp-config.php

Question

I need to add the line define('WP_POST_REVISIONS', false);

to my config.php , so that post revisions are disabled.

I don't have access to wp-config.php, I have permission to edit my theme and plugins. Is their any way i could add this code to my theme's function.php, or is their any hook to achieve it.

also,

Is their anyway to override the function which has been defined in wp-config.php for eg:

define( 'BP_DEFAULT_COMPONENT', 'profile' );

can i override the above line of code without accessing wp-config.php.

Answer 1

Use this plugin called Revision Control: http://wordpress.org/extend/plugins/revision-control/

Answer 2

Yes, the plugin can override it, use action, init with a function to disable it. for example

add_action(init,'my_disable_revision');

function my_disable_revision ()
{
 define( 'BP_DEFAULT_COMPONENT', 'profile' );
}
