Random Taxonomies on Post

Question

I have a website that shows online stores as posts, these stores can be attached to multiple brands which is a custom taxonomy.

Some of the stores have 20 brands so I would like to random show 5 brands on the store post.

I found the following code which returns 5 random brands (Displaying random Taxonomy terms in Wordpress)

<?php

$max = 5; //number of categories to display
$taxonomy = 'brands';
$terms = get_terms($taxonomy, 'orderby=name&order= ASC&hide_empty=0');

// Random order
shuffle($terms);

// Get first $max items
$terms = array_slice($terms, 0, $max);

// Sort by name
usort($terms, function($a, $b){
return strcasecmp($a->name, $b->name);
});

// Echo random terms sorted alphabetically
if ($terms) {
foreach($terms as $term) {
echo '<a href="' .get_term_link( $term, $taxonomy ) . '" title="' .  
sprintf( __( "View all posts in %s" ), $term->name ) . '" ' . '>' . $term- 
>name.'</a> ';
}
}?>

It however seems to get 5 random brands from all posts and not the current one.

Any ideas how to make this work only for taxonomies (brands) attached to the current post.

Thanks Richard

Your code is always saying to get taxonomy terms but does not specify that it should relate to the current post ID. This line should help:

$taxonomies=get_taxonomies('','names'); wp_get_post_terms($post->ID, $taxonomies, array("fields" => "names"));
