Is it possible to get a page link from its slug?

The question:

Is it possible to get a page’s permalink from the slug alone? I’m aware that you can get the page’s permalink from the ID using get_page_link():

<a href="<?php echo get_page_link(40); ?>" rel="nofollow noreferrer noopener">Map</a>

I’m curious if there is any way to do the same with the slug of a page – like this:

<a href="<?php echo get_page_link('map'); ?>" rel="nofollow noreferrer noopener">Map</a>

The Solutions:

Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.

Method 1

Is this what you are looking for:

  1. get_permalink( get_page_by_path( 'map' ) )
  2. get_permalink( get_page_by_title( 'Map' ) )
  3. home_url( '/map/' )

Method 2

I think this could be better:

function get_page_by_slug($page_slug, $output = OBJECT, $post_type = 'page' ) {
    global $wpdb;
    $page = $wpdb->get_var( $wpdb->prepare( "SELECT ID FROM $wpdb->posts WHERE post_name = %s AND post_type= %s", $page_slug, $post_type ) );
    if ( $page )
            return get_page($page, $output);
    return null;
}

following the pattern of “original” get_page_by_title of wordpress. (line 3173)

Method 3

This is a method published by Tom McFarlin on his blog:

/**
 * Returns the permalink for a page based on the incoming slug.
 *
 * @param   string  $slug   The slug of the page to which we're going to link.
 * @return  string          The permalink of the page
 * @since   1.0
 */
function wpse_4999_get_permalink_by_slug( $slug, $post_type = '' ) {

    // Initialize the permalink value
    $permalink = null;

    // Build the arguments for WP_Query
    $args = array(
        'name'          => $slug,
        'max_num_posts' => 1
    );

    // If the optional argument is set, add it to the arguments array
    if( '' != $post_type ) {
        $args = array_merge( $args, array( 'post_type' => $post_type ) );
    }

    // Run the query (and reset it)
    $query = new WP_Query( $args );
    if( $query->have_posts() ) {
        $query->the_post();
        $permalink = get_permalink( get_the_ID() );
        wp_reset_postdata();
    }
    return $permalink;
}

It works with custom post types and built-in post types (such as post and page).

Method 4

Try This:

<a href="<?php echo get_page_link( get_page_by_path( 'map' ) ); ?>" rel="nofollow noreferrer noopener">Map</a>

get_page_by_path( 'path' ) returns page/post object which can be then used by get_page_link() as it accepts post/page object and returns permalink.

Method 5

the accepted answer is wrong because hierarchical pages don’t work like that. Simply put, the slug is not always the path of the page or post. E.g. your page has a child etc. the path will be parent-slug/child-slug and get_page_by_path will fail to find child-slug this way. The proper solution is this:

function mycoolprefix_post_by_slug($the_slug, $post_type = "page"){
 $args = array(
   'name'        => $the_slug,
   'post_type'   => $post_type,
   'post_status' => 'publish',
   'numberposts' => 1
 );
 $my_page = get_posts($args)[0];
 return $my_page;
}

<a href="<?php echo mycoolprefix_post_by_slug('map'); ?>" rel="nofollow noreferrer noopener">Map</a>

Method 6

    function theme_get_permalink_by_title( $title ) {

    // Initialize the permalink value
    $permalink = null;

    // Try to get the page by the incoming title
    $page = get_page_by_title( strtolower( $title ) );

    // If the page exists, then let's get its permalink
    if( null != $page ) {
        $permalink = get_permalink( $page->ID );
    } // end if

    return $permalink;

} // end theme_get_permalink_by_title

Use this function by

if( null == theme_get_permalink_by_title( 'Register For This Site' ) ) {
  // The permalink doesn't exist, so handle this however you best see fit.
} else {
  // The page exists, so do what you need to do.
} // end if/else

Method 7

A little late, but kind of…

You can do this:
<?php $map = get_page_by_title( 'map' ); ?>
<a href="<?php echo get_page_link('$map->ID'); ?>">Map</a>

That’s how I do it 🙂
