UBB.Developers Forums UBB.threads 6 V6 Modifications V6 Mod Ideas Cookie Warnings / NoScript

After we obviously often have trouble with users not knowing what cookies are, and so on:
I would, at the time of Login, love a quick test. The cookie variable would be loaded and checked. And there would be a warning that cookies have not been set, if that was the case.

Also, a NOSCRIPT info, telling the user if Javascript has not been activated, would be a nice service.

Good idea.

Note that checking that cookies are enabled requires more than simply fetching cookies. A cookie must be set, then a redirect done to a different page (possibly the same page), then the cookie is fetched to verify that it was set. Even this procedure doesn't verify that permanent (non-session) cookies can be set, but I'm not sure whether that's critical.

Maybe HTTP_REFERER should be checked as well, since I think the script depends on that not being blocked. This would probably need to be checked the same way as cookies.

Very good idea! Very good idea!

You could use javascript in the template to set a simple cookie and then retrieve the value and if no value is returned dynamicly print some text saying so. I think using the <noscript> tag to indicate to the viewer that they do not have javascript enabled would suffice.

code:

<script language="javascript" type="text/javascript">
function readCookie(name){
  var cname = name + "=";
  var dc = document.cookie;
  if (dc.length != 0) {
    begin = dc.indexOf(cname);
    if (begin != -1) {
      begin += cname.length;
      end = dc.indexOf(";", begin);
      if (end == -1) end = dc.length;
        return unescape(dc.substring(begin, end));
    }
  }
  return null;
}

function putCookie(name, value) {
  var expires = new Date();
  expires.setTime(expires.getTime() + {$config['cookieexp']});
  document.cookie = name + "=" + escape(value) + 
  ((expires == null) ? "" : "; expires=" + expires.toGMTString()) +
  "; path={$config['cookiepath']}";
}

putCookie('dough', 1);

var isBaked = readCookie('dough');
if (isBaked == null) {
   document.write('There was a problem setting cookies. Please make sure you have cookies enabled. Thanks.<br />');
}
</script>
<noscript>
You do not seem to have javascript enabled. Please correct this now. Thanks.<br />
</noscript>

I think this code will work... lol
I haven't tried it or used it as of yet. Let me know what happens.

I have attached a text file that will allow the correct copy/pasting of the code to your template. (or at least I think it will)

I tried to copy/paste from the example I posted and the javascript failed.
