=====My Changes Action=====

==Implemented in 1.2==

Documentation: MyChangesActionInfo.>>This is the development page for the my changes action.::c::

The php code:

----
The above code doesn't sort the pages properly when sorting by time.
I have re-coded the action like this:

if(!function_exists("print_edit")) {
function print_edit(&$last, &$current, &$tag, $time) {
if ($current != $last) {
if ($last) {
print("<br />\n");
}
print("<strong>$current</strong><br />\n");
$last = $current;
}
$rev_link = "<a href='".$baseurl.$tag."/revisions'>history</a>";
$page_link ="<a href='".$baseurl.$tag."'>".$tag."</a>";
print("  (".$time.") (".$rev_link.") ".$page_link."<br />\n");
}

For a comparison of the both versions see [[http://ranta.info/TimosChanges | TimosChanges]]. That page uses the above code, but statically assumes TimoK as user, no matter if you are logged in or not.

Thanks to JavaWoman who helped me a lot tonight with questions and ideas. Without you I couldn't have done this.

The above code seems stable, safe and fast (225 out of ~260 rows fetched in 0.07 seconds compared to 0.25 seconds with the old code), but it's 1:35AM as I am writing this, so I would be happy if some others could test it on their own wikkas and let me know if there are any problems.
