Hi admins,i'm trying to extend the Category Block Controller without editing the core file,the function i want to override is the private functions.Is it possible to do that?Thanks a lot.

abolabo:
Hello.
You can look into file public_html/extensions/default_pp_pro/core/default_pp_pro.php to see how hook works.
More details here http://www.abantecart.com/document_wiki/index.php/AbanteCart_Extension%E2%80%99s_Developer_Guide#Hooks

we recommends to use our developer tools extension.
You can download and install developer tools and generate new extension with prebuilded files.

sure. You can't to hook private methods. You should to change it's output.

Also you can get variables from "view" via $this->baseobject->view->getData('some var name'); inside  _initUpdate() hook and rewrite it

Hi abolabo,i have found the way to do what i'm trying to do without modifying the core file or hook it.Actually what i want to achieve is to display the 2nd level child in category_top block.Here is what i have done in case someone want to use it too.I just edit the https://github.com/abantecart/abantecart-src/blob/master/public_html/storefront/view/default_html5/template/blocks/category_top.tpl and add this code after line 36.


--- Code: ---<?php
                                        $cat=$scat['children'];
                                        foreach ($cat as $ct) { ?>
                                        <li><a href="<?php echo $ct['href']; ?>">&nbsp;&nbsp;&nbsp;&nbsp;<?php echo $ct['name'];?></a>
                                            <img class="sub_cat_image" style="display:none" src="<?php echo $ct['thumb']; ?>"
                                                 alt="<?php echo $ct['name']; ?>"
                                                 title="<?php echo $ct['name']; ?>">
                                        </li>
                                        <?php } ?>
--- End code ---
