Yes, @toscho is right, the url
works with an array of feeds adresses. And if you have 5/6 feeds, the total of items should be 20/24.
For clear separation, I think it’s better to run the wp_widget_rss_output
function n
number of times, and prepare a previous array with titles and addresses and iterate through it. The scroll issue is just a matter of CSS.
add_action( 'wp_dashboard_setup', 'multiple_feeds_wpse_91027' );
function multiple_feeds_wpse_91027()
{
wp_add_dashboard_widget(
'dashboard_custom_feed',
'Latest News',
'dashboard_feed_output_wpse_91027'
);
}
function dashboard_feed_output_wpse_91027()
{
// Array with Title => Address
$feeds = array(
'First Feed' => 'http://example.com/feed',
'Second Feed' => 'http://example2.com/rss',
'Third Feed' => 'http://example3.com/feed/',
);
// Set max-height and enable scrolling
echo '<div style="max-height:300px;overflow-y:auto">';
foreach( $feeds as $key => $value )
{
echo "<h3>$key</h3>";
wp_widget_rss_output(array(
'url' => $value,
'items' => 4,
'show_summary' => 1
));
}
echo "</div>";
}
