Hello,
I am creating a MVC application.
Now I get the following error:
Catchable fatal error: Object of class PHP_Form could not be converted to string in /Applications/MAMP/htdocs/framing9/application/module/default/controller/user.php on line 67This is the code in my controller
public function login()
{
// require the PHP_Form class
Loader::load(PHP_Form);
$form = new PHP_Form("myform");
$element = new PHP_Form_Element_Text("field1","text","UPPERCASE only.");
$form->add($element);
$form->newline();
$element = new PHP_Form_Element_Password("field2","password");
$form->add($element);
$form->newline();
$element = new PHP_Form_Element_Textarea("field3","textarea");
$element->cols = 50;
$element->rows = 3;
$form->add($element);
$form->newline();
$element = new PHP_Form_Element_Checkbox("field4","checkbox");
$form->add($element);
$form->newline();
$element = new PHP_Form_Element_Select("field5","select");
$element->option("","");
$element->option("option1","Option 1");
$element->option("option2","Option 2");
$form->add($element);
$form->newline();
$element = new PHP_Form_Element_Select("field6","select (multiple)");
$element->multiple = true;
$element->option("option1","Option 1");
$element->option("option2","Option 2");
$element->option("option3","Option 3");
$element->option("option4","Option 4");
$form->add($element);
$form->newline();
$element = new PHP_Form_Element_Radio("field7","radio");
$element->option("option1","Option 1");
$element->option("option2","Option 2");
$form->add($element);
$form->newline();
$element = new PHP_Form_Button("Button 1","Button1Clicked");
$form->add($element);
$form->run(); [B]//line 67[/B]
$this->view->set("form","$form");
}This is my form class code
class PHP_Form {
var $form_class = "form";
var $error_class = "form_error";
var $cell_class_valid = "form_cell_valid";

var $action;
var $autobreak = false;
var $error;
var $name;
var $layout;
var $row = 0;

}
}
return $valid;
}
function populate(){
if (count($this->layout) > 0){

}
}
}

function newline(){

}
function show(){

}
}
function run(){
$this->submitted = ($_POST["form_".$this->name."_submitted"] == 1) ? true : false;
if ($this->submitted){
$this->data = $_POST["form_".$this->name];
$this->populate();
if ($this->validate()){
$function = $this->functions[$this->data["button"]];
if (function_exists($function)){ $this->show = $function(&$this->data,&$this->error,&$this->error_message); }
}
$this->show();
}else{
if (function_exists($this->onLoad)){
$function = $this->onLoad;
$this->show = ($this->show && $function(&$this->data, &$this->error));
$this->populate();
}
$this->show();
}
}
}The line in the controller for post to the view class
$this->view->set("form","$form");Can someone tell me what the problem is? Where do I have to make a change?
Thanks in advance.
