Is it smart to include labels in the if statement?

Question

I would like to have an if statement (or something that does the following) inside smarty's include tag. I have the following containing tags:

{include
        file="controls/control_input.tpl"
         //some other smarty variables
        mask=$itemType->mask
        mask=$field['mask']
        }

My goal is that if field["mask"] = to "", then mask is set to itemType->mask, otherwise it should be set to field["mask"]. However, I can't seem to add an if statement inside the include tag.

Answer 1

You can use if else condition before including the template file and then pass the mask variable inside the include tag as shown below,

{if $field['mask'] eq ""}
    {$mask = $itemType->mask}
{else}
    {$mask = $field['mask']}
{/if}

{include file="controls/control_input.tpl" mask=$mask}
