Get Category name from Post ID

Question

Is it possible to get the category name of a category given the Post ID, the following code works to get the Category Id, but how can I get the name?

<?php $post_categories = wp_get_post_categories( 4 ); echo $post_categories[0]?>

Thank!

Answer 1

here you go get_the_category( $post->ID ); will return the array of categories of that post you need to loop through the array

$category_detail=get_the_category('4');//$post->ID
foreach($category_detail as $cd){
echo $cd->cat_name;
}

get_the_category

Answer 2

doesn't

<?php get_the_category( $id ) ?>

do just that, inside the loop?

For outside:

<?php
global $post;
$categories = get_the_category($post->ID);
var_dump($categories);
?>

Answer 3

Use get_the_category() function.

$post_categories = wp_get_post_categories( 4 );
$categories = get_the_category($post_categories[0]);
var_dump($categories);

     <?php  
     // in woocommerce.php
     $cat = get_queried_object();
     $cat->term_id;
     $cat->name;
     ?>

    <?php
    // get product cat image
        if ( is_product_category() ){
            $cat = get_queried_object();
            $thumbnail_id = get_woocommerce_term_meta( $cat->term_id, 'thumbnail_id', true );
            $image = wp_get_attachment_url( $thumbnail_id );
            if ( $image ) {
                echo '<img src="' . $image . '" alt="" />';
            }       
}
?>

Answer 5

function wp_get_post_categories( $post_id = 0, $args = array() )
{
   $post_id = (int) $post_id;
   $defaults = array('fields' => 'ids');
   $args = wp_parse_args( $args, $defaults );
   $cats = wp_get_object_terms($post_id, 'category', $args);

   return $cats;
}

Here is the second argument of function wp_get_post_categories() which you can pass the attributes of receiving data.

$category_detail = get_the_category( '4',array( 'fields' => 'names' ) ); //$post->ID
foreach( $category_detail as $cd )
{
   echo $cd->name;
}

Answer 6

echo '<p>'. get_the_category( $id )[0]->name .'</p>';

is what you maybe looking for.
