Magento Module Block in Admin page

Question

I'm building a module in Magento, the frontend is all setup and working and now I've got to add a page to the Adminhtml area (Which I've done).

The issue I'm having is that I've got my Block (Namespace_Name_Block), which is all referenced in the section of my modules config.xml:

     <global>
        .....
        <blocks>
            <veridial>
                <class>Liquid11_Veridial_Block</class>
            </veridial>
        </blocks>
        .....
        </global>

Inside here I've got a function

    public function getVeridialBaseUrl(){
        // Do Something
    }

Now, this function is working fine on my Frontend page with the following code:

<?php echo $this->getVeridialBaseUrl(); ?>

However, when I use this same code on my page within the /admin section it's not working and there's nothing in my log files from this. Do I need to add some additional code, or an extra block for the Adminhtml section?

Answer 1

You didn't show much code so I'm just guessing that you didn't add your xml in the admin section. You probably have this for frontend in config.xml:

<frontend>
    <layout>
        <updates>
            <veridial>
                <file>veridial.xml</file>
            </veridial>
        </updates>
    </layout>
</frontend>

You need this one for admin section:

<adminhtml>
    <layout>
        <updates>
            <veridial>
                <file>veridial.xml</file>
            </veridial>
        </updates>
    </layout>
</adminhtml>

Answer 2

I've resolved this issue by using the following code:

Mage::getBlockSingleton('veridial/veridial');

Answer 3

Did you try to put the block class inside an Adminhtml folder?

Then the class name would be Liquid11_Veridial_Block_Adminhtml_Veridial

So you can call your block in layout file as belows.

<block type="veridial/adminhtml_veridial" name="custom.name" template="path/to/your/template.phtml" />

Now inside your .phtml file if you call any function (which resides in the block class,) it should work.
