Parse error: syntax error, unexpected '[' in line 169 [duplicate]

Answer 1

Just explode $post_event into it's own array and then act on that.

$post_event = get_post_meta($post_id, 'custom_event_date', true);
$post_dates = explode(" ", $post_event); 
$post_date = $post_dates[0];
$post_time = $post_dates[1];
$post_day = $post_dates[2];
