OK, heres all the code...
I have a BoundForm class, a BoundFormPage class, and a BoundTextField...
I create a BoundForm, add a BoundFormPage object to it, then add a
BoundTextField to the BoundFormPagethen I add the root node (the
BoundForm) to the SESSION...
The Form, and Page survive serialization, but not the TextField...I dont
know why.
// these are the class definitions
class BoundTextField{
var $name;
var $value;
function BoundTextField($name, $size, $value=""){
$this->name = $name;
print "\n";
}
function isValid(){
if (strlen(trim($value))>0){
return true;
} else {
return false;
}
}
}
class BoundForm{
function BoundForm($lName){
$name = $lName;
print "count = ".count($pages);
}
var $action;
var $method;
var $name;
var $dbName;
var $pages;
// upon instantiation, write form to session object.
function addPage($page){
if (!isset($this->pages[$page->name])){
print "adding page";
$this->pages[$page->name] = $page;
} else {
// this page already exists, so we dont want to replace it,
// or it will lose all its stored data...
print " ".$this->pages[$page->name]->name." already exists\n";
}
}
}
class BoundFormPage{
// these are the fields (BoundFormElements) that you can add to a form page.
var $fields;
var $name;
function BoundFormPage($lName){
$this->name = $lName;
//$myTextField = new BoundTextField("No", 30);
}
// will determine if the page has been successfully filled in.
function isComplete(){
for(reset($fields);$key = key($fields);next($fields)){
if (!$fields[$key].isValid()){
return false;
}
}
}
function addField(&$field){
print $field->name;
print "".count($this->fields)."";
if (!isset($this->fields[$field->name])){
print("adding field ".$field->name);
$this->fields[$field->name] = $field;
} else {
// this page already exists, so we dont want to replace it,
// or it will lose all its stored data...
print "already exists".$this->fields[$field->name]->name."\n";
}
}
}
//--
//and this code execute the sample classes above...
// get our form object back, but dont overwrite it
if (!session_is_registered("myForm")){
$myForm = new BoundForm("Application Form");
session_register("myForm");
} else {
//return $_SESSION[$formName];
session_register("myForm");
}
// construct the hierachy (note that all 'add' methods will not overwrite
existing children of same names)
$firstPage = new BoundFormPage("pageOne");
//$myTextField2 = new BoundTextField("gumber", 30);
//$firstPage->fields[$myTextField2->name] = $myTextField2;
$myTextField = new BoundTextField("CustomerNumber", 30);
$firstPage->addField($myTextField);
$myForm->addPage($firstPage);
