In a PHTML template, how would I determine if the module rendering me is a specific module?

Question

For example, I have a root template shared by all customer account pages. I want to display a link to the dashboard on all pages except the dashboard (obviously).

How could I detect the page is the dashboard (from PHTML) and hide it? Like this:

<?php if (someMagicDetectTheModuleMethod() !== 'someDashboardIdentifier'): ?>
    <a href="#">Dashboard</a>
<?php endif; ?>

Answer 1

An alternate method using only phtml is to check for the update handle in the current array of handles:

<?php if (in_array('customer_account_index', $this->getLayout()->getUpdate()->getHandles())): ?>
    <a href="#">Dashboard</a>
<?php endif; ?>

Answer 2

They layout handles would probably be the easiest way

var_dump(Mage::app()->getLayout()->getUpdate()->getHandles());

Also you can use the module name as given in the URL

var_dump(Mage::app()->getRequest()->getModuleName());

I've done this with a mixture of xml/phtml before. So in the xml you'd set some data against the block only for the dashboard layout handle:

<customer_account_index>
    <reference name="my.block">
        <action method="setData"><name>is_dashboard</name><value>1</value></action>
    </reference>
</customer_account_index>

and then in your phtml file you check if that data is set:

<?php if ($this->getIsDashboard()): ?>
    <a href="#">Dashboard</a>
<?php endif; ?>

Answer 4

You shouldn't do that in a template, you should create a block method which would have something like:

public function isDashboardPage()
{
    $page = Mage::helper('core/url')->getCurrentUrl();
    if(strpos($page, 'somedashobaridentifier') !== false) {
        return true;
    }
    return false;
}

Then you should call that method in the template:

<?php if($this->isDashboardPage()): ?>
    <a href="#">Dashboard</a>
<?php endif;?>
