Question

I have a form with an input type=file. Internet Explorer lets the user type anything they want into that input (whereas Firefox brings up a file chooser). If the user enters a blatantly invalid name, for example:

a 

and tries to submit the form, Internet Explorer does not even try to submit the form.

Is there any way for me to know that this has happened and let user know this is happening with an alert?

Answer 1

I found a better way to do this: http://www.priddypictures.co.uk/reference/fileInputProblem.htm

So, if those guys/gals are right, and form submits fine if the input does not have a name attribute then:

• write a jQuery plug-in that will (if Internet Explorer) remove the name attribute from all file inputs
• insert another hidden input into the form with a correct name
• copy the value from file input to hidden input

I might write this plug-in at some point.
