Magento 1.9.3 calling a custom block in cart page unsuccessful

Question

I have a very basic module:

app/code/local/Demo/Custom/Block/Giftproducts.php

class Demo_Custom_Block_Giftproducts extends Mage_Core_Block_Template {
 public function getGiftProducts() { 
 //code omitted
 }
}

app/code/local/Demo/Custom/etc/config.xml

<?xml version="1.0"?>
<config>
 <modules>
 <Demo_Custom>
 <version>1.0.0</version>
 </Demo_Custom>
 </modules>
 <global>
 <blocks>
 <giftproducts>
 <class>Demo_Custom_Block</class>
 </giftproducts>
 </blocks>
 </global>
</config>

app/design/frontend/custom_theme/default/layout/custom.xml

<?xml version="1.0" ?>
<layout>
 <default>
 <reference name="content">
 </reference>
 </default>
 <checkout_cart_index>
 <reference name="checkout.cart">
 <block type="custom/giftproducts" name="giftproducts" template="custom/giftproducts.phtml" />
 </reference>
 </checkout_cart_index>
</layout>

app/etc/modules/Demo_Custom.xml:

<?xml version="1.0"?>
<config>
 <modules>
 <Demo_Custom>
 <active>true</active>
 <codePool>local</codePool>
 </Demo_Custom>
 </modules>
</config>

app/design/frontend/custom_theme/default/tempalte/custom/giftproducts.phtml:

<?php
echo 'got here';

In cart.phtml I then call the block like this:

<?php echo $this->getChildHtml('giftproducts') ?>

Everything is doublechecked, seems pretty clear, cache is cleared, however I just cannot get the template to bo executed. tired various combinations of declaration in xml file, but with no luck.

Any help or guidance is much appreciated.

Answer 2

Your code seems correct, but you have not defined XML file for the layout in app/code/local/Demo/Custom/etc/config.xml.

Please define layout tag in config.xml file like below:

<layout>
 <updates>
 <custom>
 <file>custom.xml</file>
 </custom>
 </updates>
</layout>

Update: One more problem I have found that you have defined block class name as giftproducts:

<blocks>
 <giftproducts>
 <class>Demo_Custom_Block</class>
 </giftproducts>
</blocks>

but called it in custom.xml with:

<block type="custom/giftproducts" name="giftproducts" template="custom/giftproducts.phtml" />

which should be:

<block type="giftproducts/giftproducts" name="giftproducts" template="custom/giftproducts.phtml" />

in your case.

I think this should do the trick.
