Do you know that the WordPress have some useful functions to link page and archive page? Let's see them in action.
Scenario :
You would normally grab a page link via its ID but in the case that you had a localhost which install and an online install the ID was different, how you can link the page?
Get the permalink for a page by title
<a href="<?php echo get_permalink( get_page_by_title( 'about' ) ); ?>">About Me</a>
Get the permalink for a page by name
<a href="<?php echo get_permalink( get_page_by_path( 'About' ) ) ?>">About Me</a>
Get the permalink for a page by slug
<a href="<?php echo get_permalink( get_page_by_path( 'about' ) ); ?>">About Me</a>
Get the permalink for a page by parent/child
Scenario :
If you want to get the permalink using the method with child-page, then you need to pass the full slug. So, in this case we have a child page "about" with a parent pages which called "skills".
<a href="<?php echo get_permalink( get_page_by_path( 'about/skills' ) ) ?>">Skills</a
Get the link to custom post type archive page
Scenario :
If you have a custom posts loop and in the bottom you want to add "View all" link, then how you should lead to the page with all posts that type?
<a href="<?php echo get_post_type_archive_link ( 'your_post_type' ) ?>"</a>
Note:
In case that get_post_type_archive_link() returns false, make sure that you have used the argument has_archive => true when using register_post_type().
