How to add additional action buttons in a civicrm Add Event form?

Question

I have added a button in the EventInfo.tpl

 <div class="crm-submit-buttons">
           <div style="display:none">{include file="CRM/common/formButtons.tpl" location="bottom"}</div>
           <span class="approved-logic crm-button crm-button-type-upload">
            <button>Approve</button>
        </span>
           <span class="request-approval crm-button crm-button-type-upload"
            <button>Request for Approval</button>

        </div>

But when I click on Add Event under Manage Events, I see a popup which does not
show my button but when I click on add event and add it to new window it shows
the button, how can I make sure it works on both the places
1) Popup 2) New Window(which is showing currently)

Answer 1

First think its not a good practice to over-ride any core files specially templates when you can use jQuery to play around.

You can use buildform() hook to add button(s) to a form and the pop up window will recognise the button based on class or attribute and append it on popup form
