[Smarty] Defining Variables and Arrays (assign)

Due to the nature of Smarty, it's generally recommended to handle these operations on the PHP side, but in practice, that's not always feasible.

In reality, it's often necessary to create variables directly within the template.

DEFINING VARIABLES IN SMARTY

{assign var="name" value="山田"}
{assign "name" "山田"}

Simply creating a variable named 'name' is done as shown above. The second example is a shorthand.

{assign var="name" value=$user.name}

{assign var="total" value=$destroybonus+$score}

CONCATENATING STRINGS AND VARIABLES, OR VARIABLES AND VARIABLES

This feature is surprisingly useful. You can combine strings and variables to create new variables.

It's handy when you want to create multiple variables, for example, within a `foreach` loop.

{assign var='bonusImage' value="label`$bonusId`.png"}

{assign var="nextButton" value="`$color``$length`"}

COUNTING

{assign var="count" value=0}
{$count=$count+1}

$count++ does not cause an error but doesn't perform the calculation. Use this method when you need to increment in a `foreach` loop or similar.

{assign_array var="fruits" values="apple,banana,orange"}

Smarty 3 seems to no longer require a plugin for this. Thank you for the information.
