Miscellaneous Hacks - IE11 browser detection and fixes

IE11 gets along pretty well with vB4, though file downloads get a bit wonky due to some changes in how IE is detected.

Please note, that 4.2.2 and beyond ALREADY includes these changes.


In includes/functions.php find:

PHP Code:

         // detect macintosh 


Add above:

PHP Code:

// Detect Modern IE11+
        if (strpos($useragent, 'trident') !== false AND !$is['opera'] AND !$is['ie'])
        {
            preg_match('#rv:([0-9\.-]+)#', $useragent, $regs);
            $is['ie'] = $regs[1];
        } 


Next, find:

PHP Code:

if (strpos($useragent, 'gecko') !== false AND !$is['safari'] AND !$is['konqueror']) 


And replace it with

PHP Code:

if (strpos($useragent, 'gecko') !== false AND !$is['safari'] AND !$is['konqueror'] AND !$is['ie'])

Thanks for posting the fix!

Updated the detection code to better handle an IE10 case.

Thanks for this! It worked great!

my users are still reporting problems with IE11. Is there anything else that can be done short of updating ckeditor or just disabling it when IE11 is used?

What problems? You need to be specific

Your statement is to broad in scope. It would be helpful if you could list some of the problems your users are having. Thanks

They are reporting that the image dialog doesn't work, copy/paste doesn't work, can't insert the cursor into reply box or reply at all in some cases, or the site just causes the browser to crash.

Make sure your IE11 users are using the editor in Standard, not Advanced mode. The Advanced WYSIWYG editor doesn't detect/function correctly for IE11.

So when I make the above changes I get a blank page in IE11 and it never loads the forum. Any ideas what it may be?
