? on how to re-populate form fields

[Anon]

How can you have the user enter values on a form and then press submit...

if the user did not fill in all the required fields and I give the user a message saying to fill in the one you forgot...

How can a re-populate the fields they did fill in?

I guess I need to save the fields in some kind of variables and then code this...

form.field_name = $saved_form_filled;

if ($HTTP_POST_VARS && $send) {
$saved_form_filled = form.field_name;

thanks

PS. I posted this message before I tried it because I don't think it will work.
I will see.

$saved_name = '';

if ($HTTP_POST_VARS && $send) {

$saved_name = $first_name;

---

then in the form code...

<input type="text" name="first_name" value="<?= $saved_name ?>">

Typically I have my forms post to themselves and in the form generation I put the varaible that the field will be posting as the value="" of that field. Then when they post PHP get's these values and if there is a problem I re-display the form, but now it's still populated.

<input type="text" name="username" value="$username"></input>

Works great, if you aren't posting to the same script then you need to do a little more work, but it's basically the same thing.
