Answer 1

You are getting this error because updatearticle() method in your controller takes $offer_id as parameter. And you are probably getting this error when you submit your edit form.

To solve the problem you can either:

1. Change your method updatearticle($offer_id) to updatearticle($offer_id=NULL) . This way your method will have a default value of the parameter even when you don't pass one. But you will have to include $offer_id in your edit form as an input field and access it accordingly when calling $this->updatemodel->update_article() method.

2. Change you form action to admin/updatearticle/$offer_id .
