PHP Dynamic Form.

Hi ezb,

you do this by building code block which run based on which post values are set

so :

[PHP]<?php
if (isset($_POST['first_select']) and $_POST['first_select'] <> "default value" and !isset($_POST['second_select']) ) {
//
do the code to build the second select
//
}
elseif(isset($_ POST['first_select']) and $_POST['first_select'] <> "default value" and isset($_POST['second_select']) and $_POST['second_select'] <> "default value" ) {
//
do the code to save the data to the database
//
}
?>[/PHP]

does that help ?

sorry about this but the above doesnt make much snece to me.

I've got the java script working but as I though, when I select an option it basicly refreshes the form, taking all the items back to the default, was wondering if theres a way to get the same result but keeping what the user has selected in the form, purhaps taking the selected into a variable and using them as default when the form submits somehow?

Hi,

as with all of these things, there are a number of ways to achieve this..

simplest is prob using sessions so :

[PHP]<?php
session_start() ; // this needs to be executed before anything is sent to the browser - including any white space
if (!isset$_SESSIO N['form_vars']) session_registe r('form_vars');
if(!empty($_POS T['variable']) $_SESSION['form_vars']['variable'] = $_POST['variable']; // this needs to be done for all vars on the form
else $_SESSION['form_vars']['variable'] = null;
// now in the form we can set the field values to $_SESSION['form_vars']
['variable'] and this will be maintained across submissions of the form.
//*
//* build the form here
//*
// when its processed you need to do the following to clear the variables:
unset($_SESSION['form_vars'][);
// its also good practise to tidy the session record too using:
session_destroy (); // but only after you have saved your values...

?>[/PHP]

Does that help ?
