Add each selected category (not just one) to portfolio

Hi Andy
Hallo Guenni007

Thanks so much for your help. I have now managed to get my categories with this code, I have added in my child theme functions.php:

function show_portfolio_category_func() {
global $post;
$sort_classes = “”;
$item_categories = get_the_terms( $post->ID , ‘portfolio_entries’ );
ob_start();
if(is_object($item_categories) || is_array($item_categories))
{
foreach ($item_categories as $cat)
{
$sort_classes .= $cat->name.’, ‘;
}
}
echo $sort_classes .= $cat->name;
$output = ob_get_clean();
return $output;
}
add_shortcode(‘portfolio_category’, ‘show_portfolio_category_func’);

But I have the problem that it shows the last category in double (example : Geländer, Treppen, Treppen). How do I fix this?

I have changed my code to this:

function show_portfolio_category_func() {
global $post;
ob_start();
$sort_classes = “”;
$item_categories = get_the_terms( $post->ID , ‘portfolio_entries’ );
if(is_object($item_categories) || is_array($item_categories))
{
foreach ($item_categories as $cat)
{
$sort_classes .= $cat->name.'<span class=”cat-komma”>, </span>’;
}
}
echo $sort_classes;
$output = ob_get_clean();
return $output;
}
add_shortcode(‘portfolio_category’, ‘show_portfolio_category_func’);

This works for me, no double entries. I had just an extra comma at the end of the list, which I did not display with this css code:
.avia_textblock .cat-komma:last-child {
display:none;
}
Sorry, no PHP programmer. Just know some HTML & CSS :-)

Kind regards
