How to pass a variable to form?

[risoknop]

Hello,

What I need to do: pass a variable to form (so I can use it inside form class).

This is how most of my form cl***** look like:

[php]
class FormName extends Zend_Form
{
public function init()
{
// something here
}
}
[/php]

And when I do:

[php]
include APPLICATION_PATH . '/forms/FormName.php';
$form = new FormName($var);
[/php]

I need the $var to be accessible inside the form class. I tried adding the var inside init() method as well as creating a constructor and putting it there but to no success.

Any suggestions?

The first (only) parameter to the contructor of a form is an options array, which map to set* functions, so you should be able to do this (untested)
[php]
$form = new FormName(array('myOption' => 'Some Value'));

class FormName extends Zend_Form
{
protected $_myOption;

public function init()
{
$myVar = $this->_myOption;
}

public function setMyOption($value)
{
$this->_myOption = $value;
}
}
[/php]

Thanks for help

Actually, upon further investigation I found out it doesn't work. The variable $myVar is null even though I have passed a value (I checked it with var_dump()).

To clarify, I need the variable inside the form to build a multicheckbox (basically I want to pass an array of categories to form and build multicheckbox for each category inside the form class...).

I have to play the "it works for me" card. I just put the code I posted above into an app and it worked exactly as expected (I var_dump($myVar) in the init, and got "Some Value").

One thing I can think it might be is, if you changed the key in the options array to one of the "forbidden" values (I'm not sure if they are documented anywhere, I read the code).

From Zend/Form.php:
[php]
$forbidden = array(
'Options', 'Config', 'PluginLoader', 'SubForms', 'View', 'Translator',
'Attrib', 'Default',
);
[/php]

So if you used array('options' => ...) or any of the others in the list, it wouldn't work.
