Get a WordPress Page ID with the Slug
When I develop for WordPress, I start out on my local machine, then eventually migrate to the production server. This works very well, but takes a bit more work when I get to the migration stage. To make it a little easier, I use this little function to eliminate any hard-coded page IDs in navigation links or conditional statements:
function get_ID_by_slug($page_slug) {
$page = get_page_by_path($page_slug);
if ($page) {
return $page->ID;
} else {
return null;
}
}
Then, whenever we need to call a function that requires a page ID, just pass it our new function.
wp_some_function(get_ID_by_slug('any-page'));
