[wp-hackers] Problem: WP_Query() with custom field value as an array ...

[Otto]

Most obvious answer: Don't store the custom field value as a
serialized array. You can store more than one value with a meta key,
making searching for it much easier.

For example, instead of storing the array with 183 and 182 in it,
store it as two separate meta entries with the same meta key.

add_post_meta($post_id, 'keyname', 183);
add_post_meta($post_id, 'keyname', 182);

get_post_meta($post_id, 'keyname'); // returns array(183,182);
