PHP Help

I have a URL Paremeter like this

http://localhost/fullsize.php?tid=1
http://localhost/fullsize.php?tid=2

The value tid can go up unlimited, somehow I need to control this so it goes up one at a time but set a stop point i.e 4 as it starts dependant on the click for previous page.

I can make it go up by one with the following.

<a href="fullsize.php?tid=<?php echo $row_Recordset1['tid']+1; ?>

But how do I stop it where I want.

You need some kind of control structure within you PHP block. e.g.

Code:

<a href="fullsize.php?tid=<?php 

	if ($row_Recordset1['tid'] >= 4)
	{
		// Increment no more
		echo "4";
	}
	else
	{
		// Not yet reached the max limit so increment
		echo $row_Recordset1['tid']+1;
	}
	?>">Click here</a>

Thanks for the reply piper much appreciated. There is only one floor with this, the TID number will not always start on 1 it could start on any number. Any ideas on how to get around that.
