带有商店条件的ifconfig参数

Question

In Magento xml layut or config file we can write ifconfig as parameter in a tag to apply a condition like this

<action method="addLink" translate="label title" module="contacts"     ifconfig="contacts/contacts/enabled">
<label>Contact Us</label>
<url>contacts</url>
<title>Contact Us</title>
<prepare>true</prepare>
</action>

I was trying to find ifconfig alternative of this function

Mage::getStoreConfig($path,Mage::app()->getStore());

so that i can include store condition along with path in ifconfig. Any help will be appreciated.

There is no built in way to do that, mainly because the ifconfig constraint is used for the current store. When calling Mage::getStroreConfig() with only one parameter the current store is used as the second parameter. and the layout is loaded for the current store.
But if you insist, here is a possible idea on how to do it.
The action tags in the layout are parsed and applied in this method Mage_Core_Model_Layout::_generateAction(). This piece of code checks the ifconfig attribute.

if (isset($node['ifconfig']) && ($configPath = (string)$node['ifconfig'])) {
    if (!Mage::getStoreConfigFlag($configPath)) {
        return $this;
    }
}

You can override this method to allow an additional parameter for the store. So your xml code would look like this:

<action method="someMethod" ifconfig="some/config/path" store="2" />

Now change the code above that calls the action to this:

if (isset($node['ifconfig']) && ($configPath = (string)$node['ifconfig'])) {
    if (isset($node['store'])){//check config setting for supplied store
        if (!Mage::getStoreConfigFlag($configPath, $node['store'])) {
            return $this;
        }
    }
    else{//default behavior
        if (!Mage::getStoreConfigFlag($configPath)) {
            return $this;
        }
    }   
}
