Get Page ID or URL From a Slug in WordPress

Last Updated: January 11, 2021 | Reading Time: < 1 minute

This is interesting, with years experience working with WordPress, I’ve never dealt with this kind of issue. I searched the codex, and found get_page_by_path is the ideal solution instead of directly create query to database.

get_page_by_path( $page_path, $output, $post_type );

To get a page ID simply add the slug to the function

// Returns Object page ID
$page_id = grain_get_url_by_slug('slug');

I creates a function to simplify the usage

function get_url_by_slug($slug) {
    $page_url_id = get_page_by_path( $slug );
    $page_url_link = get_permalink($page_url_id);
    return $page_url_link;
}

And use it in real life

<p>
	<a href="<?php echo get_url_by_slug('services'); ?> ">
		What can we do for you?
	</a>
