Do you want to add some additional text, e.g. a footer in RSS feeds of Drupal 7?
You could provide some hints or related news.
I've found a simple solution to do this. There are certainly other solutions or places in Drupal to do this.
<?php
/**
* Adds some additional text for rss view_mode.
* Implements hook_node_view().
*/
function YOUR_MODULE_node_view($node, $view_mode) {
if (($node->type == 'article') && ($view_mode == 'rss' /*| $view_mode == 'full'*/)) {
$markup = '<hr><div class="rss-footer">' . t('Has the article been interesting? Would you like to share it?') .'</div><hr>';
$node->content['rss-footer'] = array(
//'#type' => 'markup', // The default value.
'#markup' => $markup,
'#weight' => 500,
);
}
}
?>
