Put a condition to display an iframe

Good morning,
I would like to do a very special think.
I would like that the users put their myFlightradar24's username inside their profile inside a custom field, and then I want to add an iframe to a page with the link of myFlighrradar24 : https://my.flightradar24.com/ {user}.
I do this and it works :



<div>

	<iframe id="inlineFrameExample"

	title="Inline Frame Example"

	width="100%"

	height="2850"

	src="https://my.flightradar24.com/<?php $tmpUser=JsnHelper::getUser( $user['User']['id'] ); echo $tmpUser->id_myflightradar; ?>">

	</div>

Now I would like to insert a condition. I would like to display the iframe only if the user insert his myFlighrradar24's username. If the user doesn't insert his username, I would like that we don't see the iframe.
Thanks very much for your help.
Best regards,
Yann Arnould
