Magento fatal error cannot redeclare function theme Blanco

Question

Our team has bought the Blanco theme, is a nice theme for Magento. Then after installing I tried to enter a product detail page and got this error:

Fatal error: Cannot redeclare themeOptions() (previously declared in
C:\wamp\www\magento\app\design\frontend\default\blanco\template\page\html\head.phtml:6) in
C:\wamp\www\magento\app\design\frontend\default\blanco\template\page\html\head.phtml on line 113

First I checked the provider website to read the FAQ's and any possible issue. No luck, so I posted my question there. Anyway I cannot wait for them to answer so... I searched about this error and found some suggestions here in StackOverflow, this post, this other one and some other. But the answers given there are not useful, or maybe I'm not implementing it right. Tried using the function_exist but it prevents the function from being loaded and the theme is not loaded at all on the product details page. Neither the include_once "head.html"; works.

I verified that the function is not declared anywhere else on the code.

What you recommend me to do? Is a phtml file, so it has a combination of php and html tags inside it. Here is the code:

Answer 1

This article gave a good head start to pin down the issue. I did comment out the lines suggested by Yaroslav, but it did not resolve issue for me. Then I used function_exists struct which seemed to work out. It has to used for 2 functions in the head.phtml

1) function themeOptions ($themeOption)

2) function jsString($str='')

Wrap the above functions in function_exits

if(!function_exists(themeOptions)){
function themeOptions ($themeOption) {
    //Piece of Code
    }
    }

if(!function_exists(jsString)){
    function jsString($str='') {
//Piece of Code
}
}

After this it all seems to be working fine.

Answer 2

Since this module is coded the wrong way (a php function should never be declared in a template but in a BLock!) 2 solutions for your problem :

• look at your layouts to understand why this template is included twice. Is it normal (you're trying to display this template in 2 different locations ? If so : you need to go to solution #2 since a PHP function cannot be redeclared)

• modify the module to get in work the "magento way" (MVC) : move the function declaration in a dedicated Block (in the BLock folder of the module). Declare the BLock layer in the module's config.xml if needed and link your template and Block in the module's layout XML file.

and tell the template creator to respect magento standard ;)

Answer 3

Finally the error appeared again with the fresh installation of Magento. After carefully reviewing the exception.log file and the particular phtml file where the error was found I managed to get it working by commenting a line and adding small piece of code.

This is the error from the exception.log file:

exception 'Exception' with message 'Notice: Undefined variable: tab in C:\wamp\www\magento\app\design\frontend\default\blanco\template\catalog\product\view\tabs.phtml on line 8' in C:\wamp\www\magento\app\code\core\Mage\Core\functions.php:245

Here is the guilty line on the tab.phtml file:

<?php if ($tab != $this->getChildHtml('product_custom_tab')): $last = 'last'; endif; ?>

What I've done is comment it and add a new line:

<?php //if ($tab != $this->getChildHtml('product_custom_tab')): $last = 'last'; endif; ?>
<?php $last = 'last'; ?>

Now everything seems to go smoothly, I'm checking it at this moment, product details is showing, all fancy rollovers work and tabs are ok too.
