how to display a chosen image if an user forgets other information in a form.

For regular input fields I use

<input name="checkEmail"  type="text" value="<?php echo $_POST['checkEmail'];?>" maxlength="255" />

But for an image upload this doesn't work

<input type="file" name="photo" id="file" value="<?php echo $_POST['photo'];?>"/>

How do I set input field photo to the chosen file path???

Why do u need that?

I dont realy understand this: "an user forgets other information in a form"

Oh sorry,

I meant a form with personal information, like name, address, city, email etc. After an user submits the form I check if fields are empty. If there are empty fields I display errors, but the fields already filled will be displayed by $_POST['fieldName'].

So the user just need to fill in an empty field

It all works except for the file input.

hope it's clear now

U cant do it, but u can do a javascript validation so the user dont submit untill it has all the fields prepared for submit ...

That doesn't work if the user has javascript disabled on their browser. You have to have server side checking as well.

As for why it doesn't work. HTML just simply doesn't allow it. http://www.w3schools.com/tags/tag_input.asp look down to the value field.

For a file input I don't think it's really important to stick in what the user entered. If they did enter a value and there was nothing there, you could just output "upload of file {$_POST['photo']} failed." in the error instead. Nobody really enters the pathname for the file manually like that anyways, they always click the browse button. The chances of a user entering a bad path like that is very low.

Javascript validation is not done for thoes that have javascript disabled in there browser, but for thoes that by mistake press submit ...
For thoes that test your site and disable javascript u make php validation, so both are needed ...
