File upload via HTML

[waimichael]

I use PHP to handle the file upload via HTML code like this:

...
...
$filename = $_FILES['filename']['name'];
...
...
<input name="filename" type="file" value="<?php $filename; ?>" />
...
...

However, after I submit the form, the file name in the file input box is deleted and I can't show the value again if the user input something wrong of the form. Would anyone tell me how I can show the file path in the input box again after the form is submitted?

Thanks.

Basically, you can't. This is a security issue (if the page author could specify a file, then they could specify any file they wanted, whether it's one you wanted to send them or not).

This forum illustrates one solution; if you edit a post with an attachment you'll get three radio buttons along with the "attach file" field: Delete the file, keep the current file (the default) or upload a new file (next to the file upload field).
