Set initial value for an INPUT TYPE="file"?

Hi,

Is there a way to set an initial value for the file browser INPUT? When I set 'value="foo"' the input field is blank.

Thanks,
Steve

No you can't do that. Reason being is that it is a security risk. Imagine
specifying a path to an important file (passwords, cookies, etc) and then
further imagine that the form is automatically submitted when you visit a page,
the site would now have that important file to play with as they like. Thats why
you cannot set it's value.

Depends.

It's allowed by the spec:

"[control type] file
Creates a file select control. User agents may use the value of the
value attribute as the initial file name."

and some browsers support it (Opera and Lynx for example).

Thanks for the info, Micha, wasn't aware that.

I guess that I'll be making sure to not use those browsers, as that is
definitely a big security issue, if the form can be submitted automatically via
scripting.

Not reliably. Opera may be the only browser that supports it.
