PHP forms failing in IE

June 28, 2007 8:47 AM

Any general reason why php and javascript web apps would fail in Internet Explorer and yet work correctly in Safari and Firefox? (isset($_SESSION), $form->value, etc.)

In both, print SESSION, form, form->value;

(Surely there's a strict mode where PHP doesn't allow you to deref undefined things, yes? Ghods, that language makes me wince.)

Well, the general reason would be Javascript. Or, Microsoft's despicable implementation of JS in IE. PHP can't have much to do with it. And, yes, as cmiller said, print_r($_SESSION); will help out with debugging. And alert(whatever) for debugging Javascript. And the IE developer toolbar.

I bet you've got an unterminated list or statement somewhere. IE is particularly unforgiving about having lists that look like [1,2,3,4,]. It won't generate an error or anything. Just stops.

Look at jsLint to see how cromulent your javascript is. If you have particular questions, my email's in my profile.

If all else fails to make sense, be aware of a strange and rare IE bug during SSL sessions in which POST is lost. Someone here at work is dealing with that issue right now.
