retaining data where from and script are seperate files?

[cyberspace]

As part of a site I am developing the user has the option to upload a file.

There is a size limit and it will only accept a .doc

Currently if there is an error, the form is re-displayed, with an error message - but the data input from the user disappears - which will prove a pain.

I've googled this but it all seems to be where the form and script are the same php file and i can't seem to get it to work.

How do i keep the data entered?

thanks

the data will be in the relevant superglobal $_POST or $_GET. it is just a question of pre-filling the form fields before echoing them

<?
$name = (isset($_POST['name'])) ? $_POST['name'] : "";
?>
<form method="post" action="<?=$_SERVER['PHP_SELF']?>">
<input type="text" name="name" value="[red]<?=$name?>[/red]" />
<input type="submit" name="submit" value="submit">
</form>

Thanks for that.

the thing is, if the action is <?=$_SERVER['PHP_SELF']?> though, how does it know to pass it to the processing script? As this just passes it back to itself.

This is the problem i was having

fine, change the action to the processing script. it was just an example of how to prefill the form.

e.g.

<?
session_start();
if (isset($_SESSION['temp'])){
	$temp = unserialize($_SESSION['temp']);
}
$name = isset($temp['name']) ? $temp['name'] : '';
?>
<form action="processor.php" method="post">
<input type="text" name="name" value="<?=$name?>" />
<input type="submit" name="submit" value="submit" />
</form>

<?
session_start();
$_SESSION['temp'] = serialize ($_POST);
session_write_close();
header('Location: form.php');
?>

ah ok - thanks- still having problems however. To test i simply entered an if statement, saying if there is somethng in the upload field, go to the page (using header).

But when it goes back to the page - the field is not prefilled?

sorry - i replied before i saw your second post - i will try again!

right i think i am starting to get somewhere.

Two more issues now though:

Firstly - when you go to enter something into the text box, the cursor appears half way along the line. I tried this:

$summary = isset($temp['summary']) ? $temp['summary'] : '';
$summary = trim($summary);

To no avail.

Secondly, since a user may wish to log 2 calls in the same session, i need to unset the temp variable to prevent a new post being pre-filled.

To do this i did:

unset($_SESSION['temp']);

after the SQL statements in the processing script - however this doesnt work either.

Thanks so far!
