Validation works in Firefox not IE

Thread began 12/04/2010 2:51 am by paulshoe379536 | Last modified 12/07/2010 9:44 am by paulshoe379536 | 1029 views | 3 replies |


Validation works in Firefox not IE

I am trying to use "Client Validation" for an image upload field on my form. The validation works as expected in Firefox, but always gives me a validation error in IE7 or IE8.

I am using "Alphanumeric" validation and the file name I am using for the test is "bob.jpg" (which should pass the validation).

What am I doing wrong? Is there a better way to validate the characters allowed in a file name?

I have attached a screen capture of the configuration window.

Your suggestions are appreciated.

The one thing I would probably do different is validate the file extension rather than the extension name.

You can then ensure the type of file you want to be uploaded is being uploaded. Is there a particular reason why you want to validate the file name rather than the file extension (type) ?

Best regards,

This is a classic case of ie implementing different standards in javascript than other browsers.

to pull IE out of the equation, you should validate the file field server side instead of using client side validation.

I am also validating the file type but I also wanted to make sure they weren't using unacceptable characters.

Since there's a problem with the Client Validation tool and IE, I think I'll use preg_replace to correct the invalid characters. That way, the visitor won't need to be prompted to correct their entry.
