variable not being applied after post form

infiniphunk · February 17, 2009

Hi everyone, I'm pretty new to PHP, just learning some of the basics. I hope this question doesn't sound stupid if it's been asked a thousand times before. Here goes.

I am writing a script called dslhpp.php. It has a few different parts that generate html for a webform to be used by my collegues.

One section displays a 'start' page using an 'if' statement when an option has not yet been clicked by a radio button on the form.

Once one of the radio options have been selected and the form is processed using the 'POST' method, another form is displayed for the user to fill in text areas. The user can then click another button to submit the form again as 'POST'. The problem is that variables being set in this section are not passed to the script when being submitted again, also via the 'POST' method. I'm not sure if that is really explaining my situation, I may need to show the basic structure of my script later on.

Hmm ya if you dont mind can you show the bit of script that isnt posting?

Use sessions to store the variables to transfer from page to page or on the second form create them as hidden inputs.

OK, here is what I'm trying to do, forgive my green-ness.

<?php
$option = $_POST['option'];

if ((condition a) && (condition b)) {

echo "a whole bunch of html to display a form";
... <form action=\"dslhpp.php\" method=\"post\">"; .... 
if ($option = 'a') {
etc etc
$opt = 1;
}

if ($option = 'b') {
etc etc
$opt = 2;
}

if ($option = 'c') {
etc etc
$opt = 3;
}
}

if ((condition c) && (condition d)) {

I need variable from the above section ($opt) to carry through to here.

}

etc

?>

so this is just one php file that controls the various stages of a webform. 

this script runs on an OpenBSD 4.2 webserver with apache. 

thnx

ok here goes. may seem a bit strange but that's because I've deleted a lot of info that would tell you all who I work for, haha.

I tried some stuff with $_SESSION but, still no luck. I may just have to resort to the hidden input method, but would prefer to do this properly


<?php
session_start();

$option = $_POST['option'];
$abctn = $_POST['abctn'];
$email = $_POST['email'];

if (($option != '') && ($abctn == '')) {

Thanks for your replies; I just went with using hidden input method.
