hide cms block on checkout page if customer logged in

Question

I want to hide my CMS block if customer is logged in. This is how my block is added to OPC page via local.xml file.

<opc_index_index>
    <reference name="content">
        <block type="cms/block" name="cart_sinup" before="_">
            <action method="setBlockId">
                <block_id>signup</block_id>
            </action>
        </block>
    </reference>
</opc_index_index>

Note: I cannot use <customer_logged_in> because I want this only in opc_index_index page.

Answer 1

I have solved this problem by replacing the following xml

<opc_index_index>
    <reference name="content">
        <block type="cms/block" name="cart_sinup" before="_">
            <action method="setBlockId">
                <block_id>signup</block_id>
            </action>
        </block>
    </reference>
</opc_index_index>

with

<opc_index_index>
    <reference name="content">
        <block type="core/template" name="cart_sinup" before="_" template="ds/regaddress/opc_signup_wrapper.phtml" />
    </reference>
</opc_index_index>

in my local.xml and then create a new template file

app/design/frontend/package/theme/template/ds/regaddress/opc_signup_wrapper.phtml

and add this code in it.

<?php 
    if(!Mage::getSingleton('customer/session')->isLoggedIn()){  
        echo $this->getLayout()->createBlock('cms/block')->setBlockId('signup')->toHtml(); 
    }
?>

What I'm doing here is rendering my cms_block in template file with the user logged in check and then adding this block via xml.

You can do this simply by using a css.

when you create a CMS Block assign a class or id to its container like <div class="customer_login_condition"> and on app\design\frontend\<YOUR_PACKAGE>\<YOUR_THEME>\template\page\html\footer.phtml add the css like following at the bottom of phtml.

<?php
if(Mage::getSingleton('customer/session')->isLoggedIn()){
?>
    <style>
        .customer_login_condition {display:none;}
    </style>
<?php
}
?>

Hope this helps you.

In success.phtml you could do:

if(!Mage::getSingleton('customer/session')->isLoggedIn()) {
    echo $this->getChildHtml('cart_sinup');
}

Typo in "sinup", but I just matched yours.

This will output the block if customer is not signed in, if they are signed in it will simply continue.
