Back button with file field, keep results?

[Dolemite50]

Hi,
I have a form that allows image uploads.
When I errorcheck and its missing a required field, they click the back button to fix the error. The only prob is, it retains all input field info but doesnt retain the image path for the upload. Is there a way to resolve this?

Thanks.

Let's see some 1's and 0's.

I'm not sure I follow but here you go:

That being said, all I need to know is this. Say u have a form that consists of 3 form objects; a file upload field, an input field for the title and a an input field for description.

Now say a user comes along and uploads a picture, puts in a description and forgets the title. When they click submit they go to the form action page which checks to see if there is a title and description. If there is no title then it generates an error and says to use the back button to insert a title.

When they go back to the page, the description that they input earlier is still there so they put in a title and hit submit.

At this point the code chokes because the file upload field is now blank. With this configuration I would have to rely on hoping the client noticed that the upload field didnt retain their upload path info.

So how would I re-populate the image upload field?

I thought of using a session variable to store the path and then somehow trying to pass it thru when they click back but Im not sure how or if that is a good route to go.

Thanks for the help.

By 1's and 0's I meant some code. :p

Have you tried giving them default values?

i.e.

<?php
if(isset($_POST['submit'])){
	if(empty($title) || empty($description)){
		echo "Error: Empty fields.";
		exit;
	} else {
		//check file and do the upload
	}
} else {
echo "<form action=\"$PHP_SELF\" metho=\"post\">
<input type=\"text\" name=\"title\" value=\"$title\"><br />
<input type=\"text\" name=\"description\" value=\"$description\"><br />
<input type=\"file\" name=\"myfile\" value=\"$myfile\"><br />
<input type=\"hidden\" name=\"MAX_FILE_SIZE\" value=\"2052000\"><br />
<input type=\"submit\" name=\"submit\" value\" SuBmIt! \">
</form>";
}
?>

You can use session variables to track the last values entered, however I don't know that this will work with files. The client's local path isn't part of the $_FILES array, so I don't think you could point at something that would be meaningful for the user.

Isnt this the local path?
$imagepath = $_FILES['image']['tmp_name']);
