The function search on http://php.net/search.php now works again, however it is disabled on all other php.net pages.

It doesn't work on MSIE 6 now :)

Is the *original* source to this code available somewhere? (not the obfuscated version on the web). As I would be glad to take a look over it and make it work in a wider set of browsers.

You can find all the source code here: http://cvs.php.net/phpdoc/scripts/quickref/

OK I've solved the problem with IE not working correctly.

I actually ran across the same problem while doing my own JS code dynamically adding elements using the DOM.

IE does not correctly set the 'style' attribute when using the setAttribute dom function, so you have to explicitly specify any styles via the 

object.style.cssstylename

gotta love firefox's view selected source as it'll show the "current" source with all DHTML changes, as I disabled the onblur handler selected the entire page view source and then copied it out to a temp file and loaded that in IE, where I found that the HTML is not being generated the same.

This is the lovely comment in my JS code

    nodebox.setAttribute('id',this.name+'_box');
    nodebox.appendChild(nodesrch);
    /* Setting attribute style doesn't work on IE, so manually set the styles */
    nodebox.style.position = 'absolute';

I believe that was committed with a SVN comment of "YASIEH" (yet another stupid IE hack)

Here is the required Javascript to get it working (instead of the if/else statement and the setAttribute call).
this will work in IE, Firefox and Opera 7.54

funchelper.style.backgrounColor='white';
funchelper.style.border='1px solid black';
funchelper.style.top='90px';
if (_d.all && (isnotopera=(navigator.userAgent.toLowerCase().indexOf("opera")==-1))) {
funchelper.style.width='165px';
} else {
  isnotopera=true;
  funchelper.style.minWidth='155px';
}
funchelper.style.padding='4px';
funchelper.style.fontSize='9px';
funchelper.style.display='none';
funchelper.style.position='absolute';

What is the status on this? Has anyone had a change to incorporate my changes into CVS so that this useful feature can be added and enabled on php.net?

Hi Eddie! Unless you provide us with a diff, it is not likely that we are going to incorporate your changes. Note that the current function suggestion works perfectly in quite a few browsers (I have just tested in Firefox).

Here is a weblink to the patch
http://www.outoforder.cc/downloads/patches/quickref.diff

As one of the previous comments stated, the current function suggestion code doesn't work correctly in IE.  This patch provides that fix.  This has been tested on IE 5.5, IE 6, Opera, Firefox, Mozilla 1.6, Konqueror, and Opera.

Could you have a look Gabor?

This is extremely outdated stuff which isn't really in use anymore.
