Is it possible to have several custom fields with the same name?
For example, I have a custom field called "promotion" for a CPT called "event". Sometimes there are more than one promotion applied to the same event, each for a certain type of participant. So I'd like to have one "promotion" custom field with a value "X, A" and another "promotion" custom field with a value "Y, B".
I tried to create this then retrieve it with
get_post_meta() and display the result with
print_r(), but all I get is one of the values only ("X, A").
Here's the code:
$event_promotion = get_post_meta($post->ID, "Event Promotion", true); print_r($event_promotion);
Perhaps it's just not possible to proceed this way?
