Add Piwik tag on 404 page about developer-documentation

[mnapoli]

So there is just this part that is added to the normal tracker right:

_paq.push(["setCustomVariable", 1, "error404", "1", "page"]);

@mnapoli the call to _paq.push(["setCustomVariable", 1, "error404", "1", "page"]);
should appear just before trackPageView because setCustomVariable decorates the request and track* functions send the request.

My bad, I fixed this, here is the tracking code that is online now:

<!-- Piwik -->
<script type="text/javascript">

    var _paq = _paq || [];
    _paq.push(["setCookieDomain", "*.piwik.org"]);
    _paq.push(["setCustomVariable", 1, "error404", "1", "page"]);
    _paq.push(["trackPageView"]);
    _paq.push(["enableLinkTracking"]);

    function track() {

        (function() {
            var u=(("https:" == document.location.protocol) ? "https" : "http") + "://demo.piwik.org/";
            _paq.push(["setTrackerUrl", u+"piwik.php"]);
            _paq.push(["setSiteId", "36"]);
            var d=document, g=d.createElement("script"), s=d.getElementsByTagName("script")[0]; g.type="text/javascript";
            g.defer=true; g.async=true; g.src=u+"piwik.js"; s.parentNode.insertBefore(g,s);
        })();
    }

    if (window.addEventListener) { window.addEventListener("load", track, false); }
    else if (window.attachEvent) { window.attachEvent("onload",track); }
    else {
        track();
    }
</script>
<!-- End Piwik Code -->

I noticed that this uses a custom variable to track the error, whereas http://piwik.org/faq/how-to/faq_60/ recommends tweaking the page title to contain the error message and referrer.

Which way is better (why?) and should one of both be fixed?

@mpdude it's legitimate request. do you mind opening an issue on piwik/piwik and we'll discuss there
