Content block not showing

Question

I'm trying to set up a custom block module and display it. For this question my namespace is V, module name W. I've created global config file, V_All.xml, in app/etc/modules/

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

I've also created module config file, config.xml, in app/code/local/V/W/etc/

 <?xml version="1.0"?>
 <config>
 <modules>
 <V_W>
 <version>1.0</version>
 </V_W>
 </modules>
 <global>
 <blocks>
 <w>
 <class>V_W_Block</class>
 </w>
 </blocks>
 </global>
 </config>

I've created class file for custom block, Yblock.php, at: app/code/local/V/W/Block/Yblock.php

 <?php
 class V_W_Block_Yblock extends Mage_Core_Block_Template
 { // Methods
 }
 ?>

I've created a template file, Yblock.phtml, to output custom block data in app/design/frontend/Mypackage/Mytheme/template/Z/Yblock.phtml. In it I have:

 <?php echo "Test Custom Block"; ?>

I've tried to display block via local.xml:

 <?xmlversion="1.0"encoding="UTF-8"?>
 <layoutversion="0.1.0">
 <default>
 <reference name="root">
 <reference name="content">
 <block type="w/yblock" name="yblock" template="z/yblock.phtml" before="-"/>
 </reference>
 </reference>
 </default>
 </layout>

However, nothing is displayed on browser. I've gone through my code and cannot find anything to alter. I wonder if anyone could point why "Test Custom Block" is not being displayed. I'll be grateful for all assistance.

• Amit Bera: z/yblock.phtml should be Z/Yblock.phtml as you file/folder name start with uppercase

Answer 1

The problem is resides in in you layout update xml file. You have your block defined like this.

<block type="w/yblock" name="yblock" template="z/yblock.phtml" before="-"/>

Here the template attribute is wrong. As per your template file name, it's value should beZ/Yblock.phtml instead of z/yblock.phtml. ie block attributes are case-sensitive.

The correct definition would be

<block type="w/yblock" name="yblock" template="Z/Yblock.phtml" before="-"/>

You can also resolve this problem by changing the file name to z/yblock.phtml.ie change the location of file like this : app/design/frontend/Mypackage/Mytheme/template/z/yblock.phtml

• raydona: "As per your template file name, it's value should beZ/Yblock.phtml instead of z/yblock.phtml. ie block attributes are case-sensitive" I've tried that but it does not solve problem. Any thoughts?
• Rajeev K Tomy: @raydona there may be multiple cause for this. you layout update xml file may not working. did you clear your cache after changes made?
• raydona: Hi, I've cleared cache by deleting everything from the /var/cache directory. One thing I failed to mention is that in: System -> Configuration -> Advanced and in "Disable Modules Output" listing, I do not see my module listed. It seems the module is not being registered.
• Rajeev K Tomy: @raydona put your site in develper mode and look for any log errors. Most probably you can find out an answer there
