[RESOLVED] Thought I cracked it but please help me

I have a form on a php page, depending on what is selected on the previous page different fields are displayed in the form

Some fields are required and on the next php page it sends them back to the form if the required fields are empty.

But when it sends me back the only fields displayed are those not dependant on input from the previous page.

I have put the values from the previous page into my form using

So they are transferred to the mailing page, so I can make the if empty string dependant on the same variables, how can I send the variables, and their values back to the form if required fields are left blank?

If you are using PHP sessions, you could add the field values to the $SESSION array, using the field name as the key. Then in your redirected page you would check first to see if the field is in the $POST array, and if not then check for it in the $_SESSION array.

Never heard of them, a:

How can I find out if I'm using them?

and B: how can I add my values to the $_Session array?

I'll settle for being able to find out a users previous page, and then on first form page put,

somekind of:

$prevpage = "$getenv_['???']";

if ($prevpage = "the second form url") {
echo you never filled out all required fields, please start the process again.}

You are using sessions if somewhere on each page you do a [man]session_start/man before anything gets output.

Session-handling functions

I've read that link and I've tried to use them but it looks likt it wants me to give the variables values.

<? session_start();
$_SESSION['verse_size'] = ['small']
?>

aNd it says that session start should only go on the first page and none after.

My first page is a html only form, where either a verse size is selected small, medium
or large, <input name="verse_size"> OR that can be left blank and

if they are buying a gift their select their <input name="cust_loc">

I should have sent these values to two different PHP forms, but I felt godd and wanted to be smart so I used a lot of if(isset($verse_size)) { <input type="text, etc, etc,etc

To change what fields appeared in the form depending on whether they had bought a verse or a gift.

Now, how do I assign my first page variables to the session array, so they are taken to the second, and on to the third, and brought back if required fields are left blank?

I tried various methods, some brought the same as my original result, second form ok the first time but if required fields left blank, returned to a form with only the three fields not dependant on the user input.

And other times, fields were missing on my second form the first time I was sent to it from the first form.

I'm seriously considering doing a seperate form for each of the first two forms.

I cracked it. All bloody day i messed about, checking back to php.net and trying it a different way. And finally I try it with $_session[''] in small case letters, and away we go. What a wally. Anyway, thread resolved and I'm a happy wee man.
