Get terms from multiple taxonomies

Question

I have to get all the terms from four taxonomies:

• vehicle_safely_features
• vehicle_exterior_features
• vehicle_interior_features
• vehicle_extras

I tried this:

$terms = get_terms( array( 
    'taxonomy' => 'vehicle_safely_features',
    'vehicle_exterior_features',
    'vehicle_interior_features',
    'vehicle_extras'
) );

But, it only gets terms of vehicle_safely_features and not all of the taxonomies.

Answer 1

If you want to retrieve multiple taxonomies you need to put the four taxonomies in an array, you are doing this, but you have put taxonomy=> in the array.

$terms = get_terms(
          'taxonomy' => array(
                         'vehicle_safely_features',
                         'vehicle_exterior_features',
                         'vehicle_interior_features',
                         'vehicle_extras')
);

Hope it helps

Answer 2

Incase someone get an error due to the => use below

$termsArray = get_the_terms(
    $post->ID,
    array(
        'tax1',
        'tax2',
        'tax3'
    )
)

Answer 3

wp_get_post_terms accepts multiple taxonomies as opposed to get_the_terms suggested by another answer.

$terms = wp_get_post_terms(
    $post->ID,
    array(
        'tax1',
        'tax2',
        'tax3'
    )
)
