Get category name (body classes)

[vicdilu]

Hi,

I had this code snippet in my theme, in functions.php

add_filter(‘body_class’,’add_category_to_single’);
function add_category_to_single($classes) {
if (is_single() ) {
global $post;
$terms = get_the_terms( $post->ID, ‘tribe_events_cat’ );
foreach ( $terms as $term ) {
// add category slug to the $classes array
$classes[]=$term->slug;
}
}
// return the $classes array
return $classes;
}

It was working ok, but after upgrading Events Calendar, Events Calendar Pro and the filter bar addon to the last version (3.9) in no longer working. If I display the php errors, there is this message:

Warning: Invalid argument supplied for foreach()

Any help it would be appreciated.

Thanks in advance,
Victor

Hello,

Thanks for using our plugins.

I took a look at the coding and it appears on the Events Pages the Global $post is not returning anything.

Not sure why that is no longer showing anything there. We are pretty busy today catching up from the weekend,but maybe to help out tomorrow if you are unable to get it.

Thanks

Hi Brian,

I haven’t found a solution for this yet.

If I can’t fix this, I would have to downgrade to older versions of tribe events plugins, but that isn’t a good solutution.

Looking foward for your support.

Thanks,
Victor

Ok so not much we can do with customizations, but if you use this global instead of $post:

global $wp_query;

and this for the ID:

$wp_query->posts[0]->ID

That should work.

I would also add a check if there are terms before going into the foreach loop as a event without terms with cause the foreach loop warning too.

Thanks Brian,

With your code, it work’s perfectly again.

I also added a conditional to check if there are terms before the loop.

Victor
