How to add button Approve to blog entry content in liferay?

[Chiến Ngọc, modifié il y a 10 années.]

I have workflow single approval in liferay and apply this to blogs entry . I want add button Approve to blog entry content for approver can see blog content and approve this. My opinion is :

Create hook to override view_entry_content.jsp and add button Approve .
And I will create request to approve this (when click Approve button) ,but some param as workFlowTaskId need for request is not available
Anyone has suggesion for me ?

Thanks.
