I tried to use the code below to create a new module but I got an error as the same title. Please help me check!

<?php

if (!defined('_PS_VERSION_')) exit;

include_once(_PS_MODULE_DIR_ . 'era_widget/widgetModel.php');

Your fuctions like __construct, install(), etc. aren't public.

 

 

 

 

Furthermore your (public) function hookdisplayHeader() should have a capital D -> hookDisplayHeader()

(functions are NOT case sensitive in php, but PrestaShop code standards expect it:

http://doc.prestashop.com/display/PS16/Coding+Standards#CodingStandards-Method/Functionnames

 

Also, use Era_Widget as your Class name, with First capitals, or even better EraWidget, without '_')

Hope this helps,

"Your fuctions like __construct, install(), etc. aren't public" I see many __construct functions in modules in default source wrote like I wrote above :v
