Traverse ez-multioption attribute options in EZ Publish PHP-side

I need help to traverse all options in a multioption.

I use the Product-class with a new multioption-attribute called "product_properties". I need a function to check if the optionID the user chose on the front-end matches an option in the list, and return true if a match is found.

This way I can check if e.g. the user chose 开发者_JAVA百科"Red" as the "Color" on a product.

In pseudo-code this is what I need:

Parameters: postedOptionID, currentObjectID

1. Fetch attribute "product_properties" (multioption) on object .

2. For each option for "Color" in "product_properties"

   2.1 If postedOptionID == optionID

   2.1.1 return true

Thanks

I finally found a way :)

• $product_properties_name is the name of a class-attribute that's an 'ezmultioption'-datatype. In my case it's called 'product_properties' and is an attribute on the 'Product'-class.

First get all of the object's attribute: $contentObjectAttributes = $contentObject->version($contentObject->attribute( 'current_version' ) )->contentObjectAttributes();

and then loop each and find 'product_properties':

// Loop all attributes of the object's class         
foreach(array_keys($contentObjectAttributes) as $key)        
{
    $contentObjectAttribute = $contentObjectAttributes[$key];
    $contentClassAttribute = $contentObjectAttribute->contentClassAttribute();           
    $attributeIdentifier = $contentClassAttribute->attribute("identifier");     

    // Get 'product_properties'-attribute
    if ($attributeIdentifier == $product_properties_name)
    {               
        // Get the multioption
        $multioption_list = $contentObjectAttribute->content();

        // Loop all multioption lists (Color, Make, Brand etc.)
        foreach($multioption_list->attribute('multioption_list') as $index => $option)
        {       
            // Loop through this multioption and get all options (if 'Color', get 'Blue', 'Red', 'Green' etc.)
            foreach($option['optionlist'] as $option)
            {
                $optionValue = trim($option['value']);

                // if there's a match on $optionValue, do something interesting...  
            }                                               
        }           
    }       
}
