New custom tab is not displaying below My account

Question

I am trying to create new tab "My Designs" below Customer Account section similar to "My Product like" I tried below code, but its not displaying new tab. Also followed link

config.xml

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

layout.xml

<customer_account>
        <!-- Mage_Wishlist -->
      <reference name="customer_account_navigation">
          <action method="addLink" translate="label">
          <name>design</name>
          <path>Design/</path>
          <label>My Designs</label></action>
      </reference>
</customer_account>

config.xml

<routers>
      <design>
        <use>standard</use>
          <args>
            <module>Outthink_Design</module>
            <frontName>design</frontName>
          </args>
      </design>
    </routers>

Also we included IndexController.php in app/code/local/Namespace/module/controllers &

productlike.phtml in app/design/frontend/rwd/theme_name/template/design

Is there any way to debug or where i am missing ?

Answer 1

Replace your code with this:

<customer_account>
            <!-- Mage_Wishlist -->
          <reference name="customer_account_navigation">
              <action method="addLink" translate="label" module="customer">
              <name>design</name>
              <path>design/index/index/</path>
              <label>My Designs</label></action>
          </reference>
</customer_account>
<design_index_index>
      <update handle="customer_account"/>
      <reference name="content">
                    <block type="design/index"  name="design_index"
                          template="template="design/design.phtml"" />
      </reference>        
  </design_index_index>

Please update it accordingly.

Answer 2

Try below code

<customer_account>
  <reference name="customer_account_navigation">
      <action method="addLink" translate="label">
      <name>design</name>
      <path>Design/</path>
      <label>My Designs</label></action>
  </reference>
</customer_account>

please check in your customer.xml file links are in this block

<block type="customer/account_navigation" name="customer_account_navigation" before="-" template="customer/account/navigation.phtml">

if it is some other block then replace refrence name
