Extending Plugin Model - Magento + Wordpress

Question

I haven't created a Magento module before and after a lot of research I attempted to create a module to insert wordpress avatars into blog posts inside Magento (I am using Fishpig).

Below I will list my folder structure and what I have in my files but I can't seem to get my custom module to work!

JUST TO NOTE: I am trying to extend "Fishpig_Wordpress_Model_User"

app/code/local/Splitpixel/Avatar/Fishpig/Wordpress/Model/User.php app/code/local/Splitpixel/Avatar/etc/config.xml

app/etc/modules/Splitpixel_Avatar.xml

My Splitpixel_Avatar.xml:

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <Splitpixel_Avatar>

            <!-- Whether our module is active: true or false -->
            <active>true</active>

            <!-- Which code pool to use: core, community or local -->
            <codePool>local</codePool>

        </Splitpixel_Avatar>
    </modules>
</config>

My config.xml:

> <?xml version="1.0" encoding="UTF-8"?> <config>
>     <modules>
>         <Splitpixel_Avatar>
>             <version>0.0.1</version>
>         </Splitpixel_Avatar>
>     </modules>
>     <global>
>         <models>
>             <fishpig>
>                     <wordpress>
>                             <rewrite>
>                                 <user>Splitpixel_Avatar_Fishpig_Wordpress_Model_User</user>
>                             </rewrite>
>                     </wordpress>
>             </fishpig>
>         </models>
>     </global> </config>

My app/code/local/Splitpixel/Avatar/Fishpig/Wordpress/Model/User.php:

> <?php 
> 
> class Splitpixel_Avatar_Fishpig_Wordpress_Model_User extends
> Fishpig_Wordpress_Model_User {
>     public function getUserAvatar(){
>         $imageSource = “”;
>         $avatarPostId = $this->getMetaValue(‘wp_user_avatar’);
>         $collection = Mage::getResourceModel(‘wordpress/post_collection’)->addPostTypeFilter(‘attachment’)->addFieldToFilter(‘ID’, $avatarPostId);
>         foreach($collection as $post){
>             if ($post->getId() == $avatarPostId){
>                 $imageSource =  $post->getData(‘guid’);
>                 return $imageSource;
>             }
>         }
>         return $imageSource;
>     } }
> 
> ?>

And then finally I am trying to use the new function in "template/wordpress/post/meta.phtml" by using the following code:

>  ### WORKING CODE TO GET AUTHOR NAME ###
> $post->getAuthor()->getDisplayName()
> 
>  ### MY CODE THAT DOESN'T WORK ###
> $post->getAuthor()->getUserAvatar()

The code pulls back nothing! Now it may be my code, but the most likely factor is that I have dome something wrong in my config.xml or folder sructure as this is all new to me!

Any help is REALLY appreciated, thanks!

EDIT: Posted same time as patch drop so got missed by most!

Usually when extending module classes I trail the extension of a parent method for example _construct() - As far as extending User.php I can confirm the below works;

app/etc/modules/Splitpixel_Avatar.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Splitpixel_Avatar>
            <active>true</active>
            <codePool>local</codePool>
            <depends>
                <Fishpig_Wordpress />
            </depends>
        </Splitpixel_Avatar>
    </modules>
</config> 

app/code/local/Splitpixel/Avatar/Model/User.php

<?php
class Splitpixel_Avatar_Model_User extends Fishpig_Wordpress_Model_User
{

    public function _construct()
    {
        Mage::log(__METHOD__);
        return parent::_construct();
    }

}

app/code/local/Splitpixel/Avatar/etc/config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Splitpixel_Avatar>
            <version>0.0.1</version>
        </Splitpixel_Avatar>
    </modules>
    <global>
        <models>
            <wordpress>
                <rewrite>
                    <user>Splitpixel_Avatar_Model_User</user>
                </rewrite>
            </wordpress>
        </models>
    </global>
</config>

With regards to your function to get the avatar URL, I'm a little confused as to why you're not using the functionality provided within the module already, for example;

• getGravatarUrl()
• getUserPhoto() - "The UserPhoto plugin must be installed in WordPress"
