Simple manipulations
{$item}
{$data[4]}
{$data.bar}
{*$data[bar]*}
{$data["bar"]}
{$data['bar']}
{$data.$bar_key}
{$data.obj->value}
{$data.obj->method()}
Many other combinations are allowed
{$data.foo.bar}
{$data.foo.$baz_key.$foo_key}
{$data.foo.$bar_key}
{$data.$foo_key.bar}
{$data[5].bar}
{$data[5].$bar_key}
{$data.foo.$baz_key.ls[4]}
{$data.obj->methodArgs($baz_key, 2, 2.3, "some string", $bar_key)} <-- passing parameters
{*"foo"*}
Math and embedding tags:
{$x+$y} // will output the sum of x and y.
{$data[$x+3]}
{$item=4+3} // tags within tags
{$data[4]=4+3}
{$item="this is message"} // tags within double quoted strings
Short variable assignment:
{$item=$y+2}
{$item = strlen($bar_key)} // function in assignment
{$item = intval( ($x+$y)*3 )} // as function parameter
{$data.bar=1} // assign to specific array element
{$data.foo.bar="data.foo.bar: tpl value"}
Smarty "dot" syntax (note: embedded {} are used to address ambiguities):
{$data.foo.baz.foo}
{$data.foo.$baz_key.foo}
{$data[$y+4].foo}
{$data.foo[$data.baz_key].foo}
Object chaining:
{$data.obj->getSelf($x)->method($y)}
Direct PHP function access:
{strlen("hi!")}
{if $logged_in}
Welcome, {$name}!
{else}
hi, {$user.name}
{/if}
Embedding Vars in Double Quotes
{mailto address=$user.email text="test $item test"}
{mailto address=$user.email text="test $foo_key test"}
{mailto address=$user.email text="test {$data[4]} test"}
{*mailto address=$user.email text="test {$data[barz]} test"*}
{mailto address=$user.email text="test $item.bar test"}
{mailto address=$user.email text='test {$data.barz} test'}
{mailto address=$user.email text="test {$data.barz} test"}
{mailto address=$user.email text="test {$data.barz} test"|upper}
{mailto address=$user.email text="test {$data.barz|upper} test"}
will replace $tpl_name with value
{include file="subdir/$tpl_name.tpl"}
does NOT replace $tpl_name
{mailto address=$user.email text="one,two"}
{include file="{$data.tpl_name}.tpl"}
Math
some more complicated examples
{$data[2] - $data.obj->num * !$data.foo.baz.ls[4] - 3 * 7 % $data[2]}
{if $data[2] - $data.obj->num * $data.foo.baz.ls[4] - 3 * 7 % $data[2]}
{$data.barz|truncate:"{$data[2]/2-1}"}
{$data.barz|truncate:($data[2]/2-1)}
{/if}
Escaping Smarty Parsing
name: {$user.name}
email: {$user.email}
Modifier examples
apply modifier to a variable
{$user.name|upper}
modifier with parameters
{$user.name|truncate:40:"..."}
apply modifier to a function parameter
{mailto address=$user.email text=$user.name|upper}
with parameters
{mailto address=$user.email text=$user.name|truncate:40:"..."}
apply modifier to literal string
{*"foobar"|upper*}
using date_format to format the current date
{$smarty.now|date_format:"%Y/%m/%d"}
apply modifier to a custom function
{*mailto|upper address="smarty@example.com"*}
