IE11 browser detection and fixes

1 Attachment(s)

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'])

Updated the detection code to better handle an IE10 case.

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?

I'd suggest you redo the changes carefully.

For me in vb4.2.0pl4 i have white page when upload images.
The only way to fix this so far is
<meta http-equiv="X-UA-Compatible" content="IE=9" />
in headinclude

Hoped this will fix and other little problems.
Any way thanks Zachery :)

After almost 3 years i have an issue with black screen in YouTube videos.
All videos are inserted with the default "video insert".
This happens only in IE 11, if i delete the
<meta http-equiv="X-UA-Compatible" content="IE=9" />

videos shows up correctly but than the other problems with editor an other shows up because the "meta" code fixes them.

Any one has same problem?? any solution??
vb4.2.0 (can not upgrade)

Same problem, only the removal of that tagg doesn´t make any difference at all. Would really like to solve this issue.
