No, in your first form you have code like
Well almost. I realised whilst trying to get to sleep last night that
there's a problem with this. In the first form you need:
?php
if ((!isset($_POST)) || (!isset($_POST['foo']))) {
$foo = set default value here;
$action = form2.php;
} else {
$foo = $_POST['foo'];
$action = results.php;
}
?
form method=post action=?php echo $action;?
input type=text name=foo value=?php echo $foo;? /
...
/form
This way you won't get a circular dependency. However, it means that you'll
need to provide some other way of amending the details on form2 if it's a
requirement.
and in the second form you have:
form method=post action=form1.php
input type=hidden name=foo value=?php echo $_POST['foo'];? /
...
/form
Cheers, Greg.

RE: [PHP] Forms PHP
[snip] I have a form that gets filled out and within this form there is a link to add additional information in a new form. When this information is saved I would like the browser to redirect to the previous form (this I can do) but with all the details they have already filled out still in the text boxes. What is the easiest way to do this using PHP? [/snip] By maintaining the POST (assuming you're using POST)variables and calling them into the form values when reloaded.

RE: [PHP] Forms PHP[Scanned]
If I've understood your initial email correctly another approach would be to save the contents of the form to your database and populate the form fields presented subsequently with information retrieved from the database. You can use the header function to redirect to whatever page you wish once the information has been saved.

Jay [/snip] You'll have to forgive me as I am unfamiliar with PHP, still a beginner!! So if I have a page (page1.php) which is my first page with a form. When I click a normal link within this form it takes me to page2.php. This page has another smaller form. When the submit button in this form is clicked it updates the database with no problems and displays a link - linking back to page1.php (I have decided not to use redirect). How do load the page and fill all the text boxes with the information that was already written - because this information (from page1.php, first form) has not been saved to the database yet. You probably knew this anyway - but I had to go through that process to satisfy myself!!

Wouldn't I then be saving the contents of that page twice in the database? -Original Message- From: Michael Egan [mailto:[EMAIL PROTECTED] Sent: 02 July 2003 14:53 To: PHP General Subject: RE: [PHP] Forms PHP[Scanned] If I've understood your initial email correctly another approach would be to save the contents of the form to your database and populate the form fields presented subsequently with information retrieved from the database.

For instance a href = someotherpage.php?name=GaryClick Here/a $_GET['name'] is equal to Gary You can do it for more than one variable... a href = someotherpage.php?name=Garyaddress=ChicagoClick Here/a $_GET['name'] is equal to Gary $_GET['address'] is equal to Chicago HTH!

RE: [PHP] Forms PHP - Thanks
Thanks all, I shall try these methods now. I may be a while - the form is pretty large :) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] forms PHP
I've done something similar like this: a href=javascript:window.back() Click here to go back /a In the situations in which I've used it, the form data from the previous page is still in the form fields. Potential downsides of this approach: the data has not yet been processed. Or, if it has been, you run the risk of processing it twice. Also, it may be unreliable depending on how the user's cache is set up (though I've never had any problems reported to me). So, it may or may not suit your needs.
