Smarty:assign函數(shù)

{assign var="name" value="Bob"}
{assign "name" "Bob"} {* short-hand *}

The value of $name is {$name}.

輸出：

The value of $name is Bob.

{assign var="name" value="Bob" nocache}
{assign "name" "Bob" nocache} {* short-hand *}

The value of $name is {$name}.

輸出：

The value of $name is Bob.

{assign var=running_total value=$running_total+$some_array[$row].some_value}

在包含的模板內(nèi)賦值的變量，在包含模板內(nèi)可見(jiàn)。

{include file="sub_template.tpl"}
...
{* display variable assigned in sub_template *}
{$foo}<br>
...

上面的模板是包含了下面的模板sub_template.tpl

...
{* foo will be known also in the including template *}
{assign var="foo" value="something" scope=parent}
{* bar is assigned only local in the including template *}
{assign var="bar" value="value"}
...

設(shè)置變量訪問(wèn)范圍為root，然后該變量在相關(guān)模板里面都可見(jiàn)。

{assign var=foo value="bar" scope="root"}

全局變量在任何模板內(nèi)均可見(jiàn)。

{assign var=foo value="bar" scope="global"}
{assign "foo" "bar" scope="global"} {* short-hand *}

可以使用 getTemplateVars()在PHP腳本中獲取{assign}的變量值。 這里的模板創(chuàng)建了變量$foo。

{assign var="foo" value="Smarty"}

當(dāng)模板被執(zhí)行時(shí)/執(zhí)行后，可以用以下的方式在PHP獲取到這個(gè)模板變量。

<?php

// this will output nothing as the template has not been executed
echo $smarty->getTemplateVars('foo');

// fetch the template to a variable
$whole_page = $smarty->fetch('index.tpl');

// this will output 'smarty' as the template has been executed
echo $smarty->getTemplateVars('foo');

$smarty->assign('foo','Even smarter');

// this will output 'Even smarter'
echo $smarty->getTemplateVars('foo');

?>
