put a predefined value in a Userfile ...

[kusarigama]

Hi All,

I have 2 questions:

1.
Is there a way to show a predefined userfile value (variable) in the userfiele field ?

I tried:

$test = "pictures";
<input name=userfile type=file value=<?echo$test;?>>.

2.
In I've filled in a eg: textfield is it possible to check if the field is empty or not, by not pressing the submit button.

I tried it with a "while" loop, but in vaine

Thanx in advance

1. No. There are obvious security reasons why it is not possible to pre-define the filename.

2. Think about your question "is it possible to check wether the field is empty, without pressing submit"

What would be the point of checking wether a field is empty before it is submitted? The form is not ready for processing until the user presses the submit button.

1. No. It would be a gigantic security hole in the browser if you could specify arbitrary filenames in a file upload field.

2. Some sort of javascript with a timeout. My js is really rusty at the moment - been doing too much PHP coding I think; but what you have is an onload= handler that call the function "checkfield", which checks the content of the text field and does one thing or the other depending on whether its empty or not, then sets a timeout, which calls "checkfield" at the end.

And/Or you can have an onblur= handler in the textfield itself, which checks to see if the field is empty or not.

Whichever javascript solution you use depends in part on what you want to have happen if it is empty.

2. Oh, I can think of a reason or two - e.g. a little blinking light next to a field that switches off if and when the field is filled, for example. That needs onload and onchange handlers...

I've never done it myself but hey, it could happen.
