Creating Product Programtically results empty Product name

Question

If Registered user click on button, we are creating Product Programatically. but when guest user click on button , its creating product with empty product name

button :

<button  onclick="return setproductlogin(\'<?php echo 
Mage::registry("current_product")->getId()?>\',
event);setrequestlogin();"  
id="submit-editorApply-{{rand}}" >SAVE DESIGN</button>

controllers

protected function _createProduct($type, $doSave=true, $originalProduct, $newImagePath="") 
{       
        $product = Mage::getModel('catalog/product');

        $product->setName($originalProduct->getName()); 
        $product->setDescription('what ever you need here');

        $customerId = Mage::getSingleton('customer/session')->getCustomerId();
        $product->setCreatedByCustomerId($customerId);      

        if ($doSave)
            $product->save();

        return $product;
    }

I tried below code, but didt worked for me

if($_category instanceof Mage_Catalog_Model_Category && $_category->getId()):

        $product->setName($originalProduct->getName()); 

        endif;

Edit

when Registered user upload image or text and click on "Save Design" button in link , than Product creating with "Product Name".

When Guest user upload image or text and click on "Save Design" button in link , it will ask to login, once Guest login/register , Product is creating with empty Product name

After clicking save design, it redirect to another page :

Answer 1

This will only resolve your product Name issue.
Update your form action code to below.

<?php echo $this->getUrl('example/amasty/createSimpleProductAndRedirect', array('_secure'=>(!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS']==='on'), 'id' => Mage::registry('current_product')->getId())) ?>

The product is being created without name is because you are not passing variable id which is required in your createSimpleProductAndRedirect function.

Answer 2

I looked through your code and this is normal behavior.

Your $_category variable is never assigned.
This means that the condition $_category instanceof Mage_Catalog_Model_Category will always return false.
Because of that, your line $product->setName($originalProduct->getName()); will never get executed and you end up with a product without a name.
I'm not sure what you are trying to do, because you code looks fuzzy, but I'm sure that's why the problem appears.
