If you have to change dinamically the number of items that are displayed on your feed page or do you need to set their offset via Drupal 6 Feed Rss Views Module, than this post could helps.

After googling for a couple of hours without find any solution to this issue, i tried to solve it by myself.
I would like to pass custom number of items and their offset as arguments of an url.

Something like this

http://www.yourdrupalwebsite.com/rss.xml?items-limit=5&items-offset=5

This page is a custom feed page created by the drupal's admin side .



/admin/build/views/edit/(rss-feed) (in my case)


After that you'll have to use this little hack that change a little piece of code inside the file

modules/views/plugins/views_plugin_display.inc

I found this piece of code on the line 1861. So i changed the following default settings:


$this->view->set_pager_element($this->get_option('pager_element'));$this->view->set_items_per_page($this->get_option('items_per_page'));
$this->view->set_offset($this->get_option('offset'));


and i replaced them with:


$this->view->set_items_per_page(($_GET['items-limit'] > 0) ? $_GET['items-limit'] : $this->get_option('items_per_page'));
$this->view->set_offset(($_GET['items-offset'] > 0) ? $_GET['items-offset'] :$this->get_option('offset'));


Save the file and you'll be ready to call your feed page with your custom arguments with it.

http://www.yourdrupalwebsite.com/rss.xml?items-limit=5&items-offset=5


and check the response.


Note:
You need to filter and sanitize your $_GET input values for security reasons.



Enjoy
