I was looking into the code of
scripts/refcount.php to see how it's done.
The code works fine, but unfortunately the used HTML is invalid in two ways:
- The HTML specification in there does not match to the one PmWiki uses. PmWiki uses XHTML 1.0 Transitional (see template
pub/skins/pmwiki/pmwiki.tmpl), the HTML in
refcount.php looks like HTML 4.01 Transitional. The W3C Markup Validation Service therefore returns tons of errors (Test yourself on Main/HomePage). The wrong markup is mainly:
- Each empty tag like
<br> etc requires an ending it with
<option> lists must be closed by
</option>, same applies to
- "minimized" attributes like "checked", "selected" etc must be written as "checked='checked'"
- There are two other mistakes that need to be fixed:
<form> requires an attribute named
action; should be
$_SERVER['REQUEST_URI'] or similar.
<input type='hidden' action='refcount'> is wrong, should be
<input type='hidden' name='action' value='refcount' />.
I've created a PITS entry for it.
