Wordpress类别：如何在单个帖子中显示名称，slug，描述和链接？

Question

What I want to do is, within single.php, pull different properties of the Category separately, like this:

<?php if ( have_posts() ) : ?>
    <?php while ( have_posts() ) : the_post(); ?>

        <a class="CATEGORYSLUG" href="CATEGORYLINK">
            <i class="fas CATEGORYDESCRIPTION"></i>
            <span>CATEGORYNAME</span>
        </a>

    <?php endwhile; ?>
<?php endif; ?>

To produce an end product like this:

So that I can use:

1. the category slug as a CSS class, to style each category a unique color
2. the category description as a Font Awesome class (in this case, "fa-wrench"), to assign each category a unique icon

(For this project, each post will only be assigned a single category, but I suppose a future-proof solution would need to output ALL categories assigned to the post in this format.)

So I really just need to know how to individually pull:

1. Category slug
2. Category link
3. Category description
4. Category name

Answer 1

You can use the get_the_terms() function to get all of the categories assigned to that post object and loop through each one to create your icons etc.

Below is an example, I've called each individual variable so that you can see the object properties clearly.

This will also work if you only have one category assigned.

//get all categories:
$categories = get_the_terms(get_the_ID(), 'category');

//loop through categories
foreach ($categories as $category) {
    //get variables
    $slug   = $category->slug;
    $link   = get_term_link($category->term_id);
    $descr  = $category->description;
    $name   = $category->name;

    //echo your content
    echo '<a class="'.$slug.'" href="'.$link.'"><i class="fas '.$descr.'"></i><span>'.$name.'</span></a>';
}
