php - wordpress if post is in_category display category name

Question

I want to check if a Wordpress post has category 'X, Y or Z' and if so display the name(s) of the category ('X Y or Z').

I already check and get a true of the category, but how can I show each name that has been found in_category();

if ( in_category( array( 'X', 'Y', 'Z') {
echo "yes";
}

How can I display the category name?

Answer 1

the simple answer to your question is this

get_the_category();

Using your example you can say

if (in_category( array('X', 'Y', 'Z') )) {
    echo get_the_category();
}

This tag may be used outside The Loop by passing a post ID as the parameter.
