How to use get_bloginfo_rss filter in WordPress

Alright, folks! If you’re diving into WordPress development, hooks are your best friends. Let’s talk about the get_bloginfo_rss filter. This one is pretty handy when you want to modify the RSS feed information of your blog. Now, let’s break it down step-by-step and see some live examples, shall we?

get_bloginfo_rss filter

To use the get_bloginfo_rss filter, first, you have to register it using add_filter. You can write this code into the functions.php of your activated theme or in a custom WordPress Plugin.

At WePlugins, we always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function weplugins_modify_get_bloginfo_rss_defaults which takes 2 parameters and we registered using add_filter. The first parameter get_bloginfo_rss is the name of the hook, the second parameter weplugins_modify_get_bloginfo_rss_defaults is the name of the function which needs to be called, the third parameter is the priority of calling the hook if the same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometimes, you have to remove a registered hook so you can use remove_filter to remove the get_bloginfo_rss filter.

Parameters

Below are the 2 parameters required to use this hook.

• $info: (string) Converted string value of the blog information.
• $show: (string) The type of blog information to retrieve.

Live Example 1: Modifying Blog Info in RSS Feed

Here’s a straightforward example of how you can modify the blog info in the RSS feed.

function weplugins_modify_get_bloginfo_rss_defaults($info, $show) {
    // Update the $info variable according to your website requirements and return this variable.
    return $info;
}
// Add the filter
add_filter("get_bloginfo_rss", "weplugins_modify_get_bloginfo_rss_defaults", 10, 2);

Live Example 2: Conditional Modification

In this example, we will modify the blog info conditionally based on the type of information requested.

function weplugins_conditional_modify_get_bloginfo_rss($info, $show) {
    if ($show == 'name') {
        $info = 'My Custom Blog Name';
    }
    return $info;
}
// Add the filter
add_filter("get_bloginfo_rss", "weplugins_conditional_modify_get_bloginfo_rss", 10, 2);

Live Example 3: Removing the Hook

To remove a hook callback, use the example below.

remove_filter("get_bloginfo_rss", "weplugins_modify_get_bloginfo_rss_defaults", 10, 2);

Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.
