I was able to create a dashboard modal using
add_thickbox();, triggered by a link:
<a href="#TB_inline?width=600&height=550&inlineId=my-content-id" class="thickbox">View my inline content!</a> <div id="my-content-id" style="display:none;"> <p> This is my hidden content! It will appear in ThickBox when the link is clicked. </p>
But actually I want it to work like this:
1) When the logged in user is redirected to the dashboard for the first time (and only the first time), the modal should appear automatically, with a button to remove the modal if user don't want to see the movie (please see the following screenshot):
Can someone help me with this implementation?
Thank you very much.
