Smarty 3 now has an incredibly useful {for} tag for easy looping with a simple, clean syntax. Example, looping 5 times:

Code:
{for $x = 1 to 5}
  {$x}
{/for}


output:

1
2
3
4
5

Here is another example stepping by 2:

Code:
{for $x = 1 to 10 step 2}
  {$x}
{/for}


output:

1
3
5
7
9

You can also use any valid expressions:

Code:
{for $x = abs($min-1) to count($foo)}
 ...
{/for}



Inside the loop the following special vars can be accessed:

Code:
$x@iteration = number of iteration
$x@total = total number of iterations
$x@first = true on first iteration
$x@last = true on last iteration
