php - Is it possible to store date as meta_key in wordpress? -


i'm trying store dates , holidays in post_meta in wordpress database. made custom post type store data. in table wp_post, store _event_date = date , _event_holiday = holiday. problem can't query date has holiday want query. thinking store dates in "meta_key" fields, values stored in meta_keys needs have underscore. hesitate it.

my current codes follows.

this how store current data in wp_postmeta.

add_post_meta($post->id, "_event_name", $_post["_event_name"]); add_post_meta($post->id, "_event_date", $_post["_event_date"]);

this want instead. 

add_post_meta($post->id, $_post[_event_date], $_post["_event_name"]);

would method have problems wordpress or something?

you may use without underscore this

add_post_meta($post->id, $_post['event_date'], $_post['event_name']);

but, if need store using preceding underscore may use , there won't problem. btw, have this:

add_post_meta($post->id, $_post[_event_date], $_post["_event_name"]);

you should use quotes (single/double) $_post['_event_date'] if not typo.
