Embedding Vars in Double Quotes

Embedding Vars in Double Quotes

Smarty will recognize assigned variables embedded in double quotes so long as the variables contain only numbers, letters, underscores and brackets []. With any other characters (period, object reference, etc.) the variable must be surrounded by backticks. You cannot embed modifiers, they must always be applied outside of quotes.

Example 3-5. embedded quotes syntax

SYNTAX EXAMPLES:
{func var="test $foo test"}       <-- sees $foo
{func var="test $foo_bar test"}   <-- sees $foo_bar
{func var="test $foo[0] test"}    <-- sees $foo[0]
{func var="test $foo[bar] test"}  <-- sees $foo[bar]
{func var="test $foo.bar test"}   <-- sees $foo (not $foo.bar)
{func var="test `$foo.bar` test"} <-- sees $foo.bar
{func var="test `$foo.bar` test"|escape} <-- modifiers outside quotes!

PRACTICAL EXAMPLES:
{include file="subdir/$tpl_name.tpl"} <-- will replace $tpl_name with value
{cycle values="one,two,`$smarty.config.myval`"} <-- must have backticks
