Sticky value in type=file input tag Options

[tonym]

I have a php script with an <input type='file' class='browse'.......> tag in the form and I would like to make this value sticky. I get the file name ok when I submit the form; how do I put the retrieved value back in the box when the form reloads? Using <input type='file' value='filename' class='browse' .....> doesn't appear to work.
Thanks

AFAIK, you can't. It's a security issue.

Some of the systems I use will store the uploaded file on the server, providing a link to it on the updated form, and requiring a file upload only if the user wants to change the file.

If you are not bothered about the security then you can do this,

CODE

//get the value of the input field (<input type="file" id="file">) using
var filename = document.getElementById('file').value;
//put this in some hidden input field (<input type="hidden" name="ctfilename" id="ctfilename">) using
document.getElementById('ctfilename').value = filename;

This will be captured at server and then you can do whatever you want.

But bear in mind this is security issue.
