Magento registry variables in controller

Question

I have stored a variable in register by Mage::register('captcha', $var); in helper. And in the controller i tried to retrieve the variable by using Mage::registry('captcha'); But i dont getting any values here. Please help me to solve this.

Answer 1

In your helper file create a function like below :

public function getCaptcha(){
    $var = 'myValue123';
    Mage::register('varun', $var);
    return Mage::registry('varun');
}

In your controller function:

$registryValue = Mage::helper('yourModule')->getCaptcha();
echo registryValue ; //prints myValue123

Hope it helps !!!

Answer 2

It's look like syntax is right. Please first try to set some static value like $var="test"

Mage::register('captcha', $var);

after that got this value in controller.

Mage::registry('captcha');

if you got this value test then i think you have problem with $var in your helper.

Let me know if you have any problem

Answer 3

'captcha' is already in use, so magento never set your data in registry. Change the name, for example 'captcha1'

Mage::register('captcha1', $var);
