Query multiple meta values
I'm working on a 'checkbox filter' to query posts by checked values. See
this link (EDIT: As you can see there are just 2 posts in this link, as
soon as the user checks for 'MINI' it gets a good result, as soon as the
user checks 'MINI' and 'COMPACT', it gives no results instead of the 2
posts). Now it works if the user only checks 1 value. As soon as the user
the checks more then one it will give no results. I'm using following meta
query code (it's part of a longer code, that's why there is the if
statement):
if (gap_meta_values($key, $value)) {
$args['meta_query'][] = array(
'key' => $key,
'value' => $value,
'compare' => 'LIKE'
);
So this works if there is only 1 meta value. However if there are more
than one values it does not work. So I tried several things to get it
work, I tought it was because there's no relation between the key and
value. So I tried this:
if (gap_meta_values($key, $value)) {
$args['meta_query'][] = array(
'relation' => 'OR',
array (
'key' => $key,
'value' => $value,
'compare' => 'LIKE'
)
);
}
But this neither seem to work. How to make this works so it will query all
posts from the checked values? Thanks for your response.
