Using integers within Smarty

How do you create an integer variable, assign it a value, compare the value of the variable with an integer and then increment the variable using Smarty?

I've tried to do this but always manage to print out the arithmatic, e.g.

I want to count the number of lines of HTML that I create so I have a variable $lines which I set to 0, $lines=0.

For each line of HTML created I increment the variable, $lines=$lines+1.

I then test to see if 12 or more lines of HTML have been created, {if $lines >= 12}

When I do this the resultant HTML shows the variable being incremented, e.g. line 4 has "0+1+1+1+1"

I don't want to output numbers I just want to use them to control my output.

Thanks Yurij,

That works a treat, and I would never have guessed the syntax for incrementing.

Re: Using integers within Smarty

Don't use math - its slow. Just use assign:

PHP Code:


		
			
{assign var="test" value="`$test+1`"}

Depending on what exactly you are trying to do you also might look at the Smarty cycle function.
