in a SMARTY section is there anyway to pass 2 variables in the same { } IE $variable and $number as {$variable_$number}

{$variable}_{$number} is not giving the results I think i am looking for

Code:

<input type="text" name="feet_{$smarty.section.a.iteration}" value="{$feet}" size="10">


is what I have that works in the name= field

but on the value=" I am looking for $feet_$smarty.section.a.iteration and

Code:

{$feet_$smarty.section.a.iteration}

is not working for me

It would be helpful if you could post some more of the code around that line so we could get a better idea of what you're trying to achieve. If you're just trying to print 2 variables then the best way is:

Code:
{$variable1}_{$variable2}


Or you could use the modifier cat to put the 2 together:

Code:
{$variable1|cat:"_"|cat:$variable2}


Not sure if this is what you're looking for but without more information I dunno what else to tell ya. :/

He's trying to do a var-var and Smarty doesn't support that. Use an array instead. So where you might have:

Quote:
$foo_1 = foo
$foo_2 = bar
$foo_3 = baz
$foo_4 = zub


rather use:
Quote:
$foo = array(
'1'=>'foo',
'2'=>'bar',
'3'=>'baz',
'4'=>'zub' )

So that you can then do:
Code:
{assign var=num value=3}
{$foo.$num}
