Template:Warning origin/doc

Usage
This template adds a line below a warning to list: the original location (defaults to page-user's talkpage); original posting user; original posting time-and-date; and/or the diff of the original warning.

This may be useful if you want to indicate the author and time-and-date of an unsigned warning; if you archive warnings off your talk page; or if you want to quote a warning anywhere else.

Parameters
This template takes four expected parameters (not required, but expected either in sequence or by named variable):
 * 1) location=   The page where this warning was originally posted (without double-brackets). If you are using this template in your own userspace, for instance on your own /Warnings subpage, location defaults to your own talkpage .  If you are using this template outside your own userspace, or referring to a warning posted on any other page, then specify the pagename (without double-brackets) as location=pagename.
 * 2) user=   The username who posted it (without the "User:" prefix); if unsigned, see [ your talkpage history ].
 * 3) time=   The UTC time-and-date of the original warning, as seen first in its entry on [ your talkpage history ].
 * 4) oldid=   The "oldid=" number of the warning's diff, as seen in the URLs of the entry's "(cur)", "(last)", and time-and-date links.

Examples
For the least typing, just provide the values in location - user - time - oldid sequence:
 * Code:
 * Result:

If the named variables are used, these don't need to be kept in the same sequence:
 * Code:
 * Result:

As long as the correct "oldid" is provided, the location is not really necessary:
 * Code:
 * Result:

If other values are left out, the template will simply bypass them:
 * Code:
 * Result:
