a button that can only be clicked once, EVER
<p>as the title said
i would like to create a button that says "available" and once any one clicks it it turns to "unavailable" for all future users
any ideas ?</p>

<p>note : its for a school project, nothing fancy or even secured, just trying to prove a point</p>

<p>sorry for being vague for some, all i am trying to do is to create an article in my joomla website with a button that only the fastest user can access and click, thats it
i am not worried with security or even cheating attempts
joomla articles can have php js codes among others added to them</p>
