is_date() WP 1.5.0
Determines whether the date archive page is displayed. Conditional tag.
This function is part of is_archive() check and contains in itself: is_day(), is_month(), is_year() and etc. (see example 2)
Works based on: WP_Query::is_date()
1 time = 0.00006s = very fast | 50000 times = 0.02s = speed of light
No Hooks.
Return
true/false. Whether the query is for an existing date archive.
Usage
is_date();
Examples
#1 Basic usage
if( is_date() ) echo "It's an archive by date"; else echo "It's not an archive by date";
#2 What checks are included in is_date()
is_date() contains in itself functions is_day(), is_month(), is_year() and etc.
This example demonstrates how not to do:
if( is_date() ) echo "It's an archive by date"; elseif( is_day() ) echo "It's an archive by day"; else echo "This is something else";
In this example, the is_day() condition will never be met. It needs to be checked before is_date().
Notes
- Global. WP_Query. $wp_query WordPress Query object.
