Magento custom module blocks and config.xml help

Question

I have created a custom module but having a little difficulty with blocks in the config.xml

For some reason I'm not able to get the blocks to show on the dump of all the xml...maybe I've missed something?

I have the following structure:

app\code\local\Site\SiteTest\etc\config.xml

app\code\local\Site\SiteTest\Block\test.php

<?xml version="1.0" encoding="UTF-8"?>
<config>
 <modules>
 <Site_Test>
 <version>1.0.0</version>
 </Site_Test>
 </modules> 
 <global>
 <blocks>
 <highest>
 <class>Site_Block</class>
 </highest>
 </blocks>
 </global>
</config>

I am trying to link this to a custom layout for example:

<block type="sitetest/test" name="home.catalog.product.test" template="catalog/product/test.phtml" after="cms_page">

If anyone could shed some light on this would really be appreciated.

Answer 1

Since you have provided less info about your module I can suggest the following corrections only. Hope it might useful.

1). There are some mis-configurations in your config.xml file. See the below code (corrected one)

<?xml version="1.0" encoding="UTF-8"?>
<config>
 <modules>
 <Site_SiteTest><!--use 'Namespace_Module' -->
 <version>1.0.0</version>
 </Site_Test>
 </modules> 
 <global>
 <blocks>
 <sitetest> <!-- this node can be anything, But as standard use the lowercase name of your module-->
 <class>Site_SiteTest_Block</class><!-- put entire path upto Block folder-->
 </sitetest>
 </blocks>
 </global>
</config>

2). Rename your block class file as Test.php

So the block class declaration should be as follow.

<?php
class Site_SiteTest_Block_Test extends Mage_Core_Block_Template
{
//your code here.
}

3). Make sure you have written the module activation file in app/etc/modules folder. It should be Site_SiteTest.xml with the following content.

<config>
 <modules>
 <Site_SiteTest>
 <active>true</active>
 <codePool>local</codePool>
 </Site_SiteTest>
 </modules>
</config>

4). Make sure the cache is disabled. (go to System > Cache Management and select all, then disabled them)

• user9178: Thanks a bunch this helped! May have one or two more questions later though :)
• Sukeshini: Glad to hear that it helped you :)
• user9178: Ok so I now have: <sitetest> <class>Site_Test_Block</class> </sitetest> Within my ?showConfig=true...however I seem to be having trouble linking this to a custom XML layout. <block type="test/test" name="test" template="catalog/product/test.phtml" after="cms_page"> Sorry more tests than anything else lol
• user9178: The last test would be the .php file so ermm if I have this right.... <block type="modulename/filename">
• user9178: Ok I think I've got it sorted however I have been given the following error when loading the page: Fatal error: Class 'Site_Test_Block_Test' not found in C:\wamp\www\magento\app\code\core\Mage\Core\Model\Layout.php on line 491
