What is the IP shortcode?

[show_user_ip] display ip of current user

With IP shortcode you can retrieve your user IP.

I use a CDN and [show_user_ip] shows the wrong address

The shortcode reads a forwarded header only when the request reaches your site through a proxy it recognises. Local reverse proxies and Cloudflare are already in the list. For any other CDN, add its ranges:

add_filter( 'cys_trusted_proxies', function ( $proxies ) {
    $proxies[] = '203.0.113.0/24';
    return $proxies;
} );

Ask your host or your CDN which ranges to use. Getting it wrong breaks nothing, the shortcode simply falls back to the address of whoever opened the connection.

Why is the page with [show_user_ip] not cached?

Because that shortcode prints something different for every visitor, so the page has to be built on each request. If you also cache at the edge, exclude the page there as well.

How work year format attribute?

For shortcode with year you can choose format with attribute format=»». It support «Y» (es.2026) or «y» (es.26). Default format without attribute is «Y».
You must enter year attribute in the same format.

How work year, month and day offset attribute?

For [y], [m] and [d] the offset is a plain number with + or -, from -1000 to 1000.
For [dmy] the number needs a unit after it: years, months, weeks, days, hours, minutes, seconds. Also «today», «yesterday» and «tomorrow» work.
Offsets follow the timezone of your site, the one in Settings > General.

Example
[d offset=»+1″] 13 (if current day is 12)
[m offset=»+1″] May (if current month is April)
[y offset=»+1″] 2027 (if current year is 2026)
[dmy offset=»+1 year»] 12/04/2027
[dmy offset=»tomorrow»] 13/04/2026
