Plugin Description
Display feeds in your blog, using PHP, a Widget or Shortcode. The plugin uses only standard WordPress functionality, so no external libraries are required. For older versions of WordPress, the built-in MagpieRSS library is used. For WordPress 2.8 and newer, there is a setting available to enable the built-in SimplePie library for parsing feeds.
As with all other content you publish, make sure you are allowed to (re-)publish the content of the feeds you are about to import!
You can insert the following code into a PHP plugin or in a template, for example sidebar.php or single.php:
Example:
<?php RSSImport(10, ‘https://bueltge.de/feed/’); ?>
This is the minimal code needed for using the plugin. The plugin accepts a number of parameters for customizing the feed content import. See below for the full list of available parameters. You can also use any of the parameters with Shortcode in posts and pages.
Example Shortcode:
[RSSImport display=”5″ feedurl=”https://bueltge.de/feed/” use_simplepie=”true”]
For all (bool) parameters you can either use the strings true and false or the integer values 1 and 0.

Default is false if used with Shortcode, true if used with the PHP function.view – (bool) If true, calling the RSSImport() function will print the rendered HTML directly to the output. If false, the rendered HTML will be returned by the function as a string value and nothing will be output. Default when using PHP code is true.

Default when using Shortcode is false.order – (string) Order of the filds Date, Title, Creator, Description. Use a comma separated string for your order. Default is date,title,creator,description
The parameters before_desc, after_desc, start_item and end_item accepts the following variables which will be replaced:
%title% for the title of the entry%href% for the entry’s URL%picture_url% for the URL of a thumbnail image for the entry if available. To use this variable, SimplePie is required to be enabled (use_simplepie="true")
If pagination is enabled, it adds a div with the class rsspaging to enable easier styling with CSS. You can also style the previous and next links, which have the classes: rsspaging_prev and rsspaging_next.
You can use any of the parameters in the php function RSSImport() in your templates or with the Shortcode [RSSImport] in posts and pages.
Examples
Using the PHP function with many parameters:
RSSImport(
$display = 5, $feedurl = 'https://bueltge.de/feed/',
$before_desc = '', $displaydescriptions = false, $after_desc = '', $html = false, $truncatedescchar = 200, $truncatedescstring = ' ... ',
$truncatetitlechar = '', $truncatetitlestring = ' ... ',
$before_date = ' <small>', $date = false, $after_date = '</small>',
$before_creator = ' <small>', $creator = false, $after_creator = '</small>',
$start_items = '<ul>', $end_items = '</ul>',
$start_item = '<li>', $end_item = '</li>'
);
Please note that for the PHP function the parameters are expected in the order in which they are defined in the above list. Thus if you skip one parameter, you will also have to skip all of the subsequent parameters.
Using Shortcode with several parameters:
[RSSImport display="10" feedurl="https://your_feed_url/"
displaydescriptions="true" html="true"
start_items="<ol>" end_items="</ol>" paging="true" use_simplepie="true"]
Add a “more” link to the output:
RSSImport(
$display = 5,
$feedurl = 'https://bueltge.de/feed/',
$before_desc = '',
$displaydescriptions = true,
$after_desc = ' <a href="%href%" target="_blank">show more</a>'
);
or
[RSSImport feedurl="https://wordpress.org/news/feed/" after_desc=" <a href='%href%' target='_blank'>show more</a>" displaydescriptions="true" use_simplepie="true"]
Enable Thumbnail Pictures:
RSSImport(
$display = 5,
$feedurl = 'https://bueltge.de/feed/',
$before_desc = '<img src="%picture_url%" alt="">',
$displaydescriptions = true
);
or
[RSSImport feedurl="https://wordpress.org/news/feed/" displaydescriptions="true" before_desc="<div><img src='%picture_url%' width='50px' alt='' style='float:left;' />" after_desc="</div>" use_simplepie="true"]
