如何在Wordpress页面上使用get_the_tags?

I've added tags to my Wordpress pages (which are working fine) but I'm trying to list them on the page.

The idea is to get all the tags a particular page (not post) has and format them. What I'm getting is either 2 random (unrelated) tags, or the entire tag list. I'm not sure what I'm missing here.

$relatedArea = the_slug(false); //gets the slug of the page - false represses the echo statement

$allTags = get_tags(); //gets all the tags
$areasOfLaw = array(); //starts the array

// check if the tag is included on the page
foreach ($allTags as $tag) {
  if(has_tag($relatedArea)) {
    $areasOfLaw[] = $tag; //add to the array
  }
}

Tried $areasOfLaw = get_the_tags() but it gave me random tags.

Here's the formatting, but I'm pretty sure it's working correctly.

foreach($areasOfLaw as $tag){
    echo '
        <a href="'.get_site_url().'/services/'.$tag->slug.'">
        <li>'.$tag->name.'
        <span class="glyphicon glyphicon-chevron-right pull-right action"></span>
        </li></a>';
    }

edit: this is my tag support included in the functions file

// add tag support to pages
function tags_support_all() {
    register_taxonomy_for_object_type('post_tag', 'page');
}

// ensure all tags are included in queries
function tags_support_query($wp_query) {
    if ($wp_query->get('tag')) $wp_query->set('post_type', 'any');
}

// tag hooks
add_action('init', 'tags_support_all');
add_action('pre_get_posts', 'tags_support_query');

    The get_the_tags() function returns all the tags associated with a post and if you use it inside the loop then you may use it like this:

    $tags = get_the_tags();
    

    But if you use it outside of the loop then you have to supply the ID of the post for which you want to retrieve that tags, for example to get all the tags of post whose ID is 10:

    $tags = get_the_tags(10);
    

    Now you can loop $tags like this:

    foreach($tags as $tag)
    {
        echo $tag->name . ' ';
    }
