Custom field value as WP_query tag parameter

Hello all

I’m trying to grab posts that have a tag that matches a custom field on the invoked page. (the custom field key is ‘masonry-tag’). on pages without this custom field populated, I am getting all posts, which is good. However, on pages where a the field *is* populated, no results are returned.

i can get the tag value to spit out just fine, so I know I’m capturing the value. Here’s my testing code:

`$filtervalues = get_post_custom_values(‘masonry-tag’);
foreach ( $filtervalues as $value){
echo $value;
};`

but when I try to call the query, i get nothing. Code for that here:

`$args = array(
‘post_type’ => array(‘product’, ‘post’),
‘posts_per_page’ => -1,
‘tag__in’ => get_post_custom_values(‘masonry-tag’)
);

$query = new WP_Query( $mix_args );
`

I’ve been at this particular bug for hours, trying different approaches. PHP really isn’t my strong suit, and I fear I’m going in circles at this point.

Can anybody point me in the right direction here?

Thanks so much in advance for your help
