I want to echo the term slug for each post on an archive page.
To get the term slug i'm using the following code:
$terms = get_the_terms( get_the_ID(), 'type_kennisbank' );
That returns me the data that I want:
array(1) { [0]=> object(WP_Term)#18648 (11) { ["term_id"]=> int(28) ["name"]=>
string(10) "Whitepaper" ["slug"]=> string(10) "whitepaper" ["term_group"]=>
int(0) ["term_taxonomy_id"]=> int(28) ["taxonomy"]=> string(15)
"type_kennisbank" ["description"]=> string(0) "" ["parent"]=> int(0)
["count"]=> int(3) ["filter"]=> string(3) "raw" ["term_order"]=> string(1) "0" } }
If I want to echo the slug I'm using:
echo $terms["slug"]
However it returns nothing. I already found a solution to echo the term slug but I'm wondering why my own echo code doesn't return the slug.
Anyone who can explain this?

Reset to default 2The get_the_terms function returns array of WP_Term objects.
So you need to use something like this to echo a single term slug:
echo $terms[0]->slug;
Also be aware of results of this function. As documentation says it returns:
Array of WP_Term objects on success, false if there are no terms or the post does not exist, WP_Error on failure.
So you need some checks before trying to echo terms. The following code may help you.
$terms = get_the_terms( get_the_ID(), 'type_kennisbank' );
if ( $terms && ! is_wp_error( $terms ) ) {
foreach ( $terms as $term ) {
echo $term->slug;
}
}
$termsis an array and each item is an object. E.g. For the data in your question, you can doecho $terms[0]->slug;to display the term slug. – Sally CJ Commented Dec 12, 2018 at 14:49get_the_terms()could return aWP_Errorinstance, or that the array could contain two or more items. All the best! – Sally CJ Commented Dec 13, 2018 at 2:03
