Home » Functions » trailingslashit

WordPress developers often need to manipulate URLs programmatically. One common operation is adding a trailing slash to a URL. The trailingslashit function in WordPress is used to automatically add a trailing slash ("/") to a given URL if it doesn’t already have one.

This function is particularly useful for developers who may be generating URLs dynamically and want to ensure consistency in their URLs. By appending a trailing slash to a URL, developers can avoid 404 errors and improve readability for both humans and search engines.

The syntax for the trailingslashit function is simple:

trailingslashit( $string )

where $string is the URL to which you want to add a trailing slash.

Here is an example of how to use trailingslashit in a WordPress plugin:

$url = 'https://example.com/my-page';
$new_url = trailingslashit( $url );
echo $new_url;

In this example, the trailingslashit function will append a trailing slash to the $url variable if it doesn’t already have one. The resulting output will be:

https://example.com/my-page/

Overall, the trailingslashit function is a useful tool for WordPress developers who want to ensure consistency and avoid errors in their URLs.
