Your can write your php code in your smarty template and its true. But you have to check for some global settings of smarty to do this.
There is a smarty variable “$php_handling” that decides how the php code should be handled by the smarty engine. The possible four values of this variable are:
- SMARTY_PHP_PASSTHRU – Smarty echos tags as-is.
- SMARTY_PHP_QUOTE – Smarty quotes the tags as html entities.
- SMARTY_PHP_REMOVE – Smarty removes the tags from the templates.
- SMARTY_PHP_ALLOW – Smarty will execute the tags as PHP code.
from the above four SMARTY_PHP_PASSTHRU is the default setting.
you can change this variable value to work with php code as follows:
<?php
require(‘Smarty.class.php’);
$smarty = new Smarty;
$smarty->php_handling = SMARTY_PHP_ALLOW;
?>
after enabling this varialbe to allow the php code in smarty, to write php code in smarty you just have to write the php code inside the {php}{/php} tags.
i.e. {php}
//your php code here
{/php}
One more thing, there is another variable ‘$security_settings’.
These settings are used to override when security is enabled. The possible settings are:
- PHP_HANDLING – true/false. If set to true, the $php_handling setting is not checked for security.
- IF_FUNCS – This is an array of the names of permitted PHP functions in IF statements.
- INCLUDE_ANY – true/false. If set to true, any template can be included from the file system, regardless of the $secure_dir list.
- PHP_TAGS – true/false. If set to true, {php}{/php} tags are permitted in the templates.
- MODIFIER_FUNCS – This is an array of the names of permitted PHP functions used as variable modifiers.
- ALLOW_CONSTANTS – true/false. If set to true, constants via {$smarty.const.name} are allowed in the templates. The defaults is set to “false” for security.
to change or access these setting you can write the code as follows:
$smarty->security_settings['ALLOW_CONSTANTS'] = true;
