You need PHP5 to use this trick

I use a cool way to assign my template's var, using PHP5' SPL.

I create an object which extends smarty and Implements ArrayAccess :

Code:

class Template extends Smarty implements ArrayAccess {
/**
* Indicate if an a var is assigned
*
* @param string $name Var name
*/
public function    offsetExists($name) {
   return (isset($this->_tpl_vars[$name]));
}

/**
* Get an assigned var's value
*
* @param string $name Var name
*/
public function    offsetGet($name) {
   return ($this->_tpl_vars[$name]);
}

/**
* Assign template's var
*
* @param string $name Var name
* @param mixed $value Value
*/
public function    offsetSet($name, $value) {
   $this->assign($name, $value);
}

/**
* Unset template's var
*
* @param string $name Var name
*/
public function    offsetUnset($name) {
   if (isset($this->_tpl_vars[$name])) {
      unset($this->_tpl_vars[$name]);
   }
   return (true);
}
}

From now, you can use Template like Smarty (assign, fetch, etc...)

AND

assign your vars like if Template was an array :

Code:

// Assign a var
$template["geeting"] = "Hello, bob !";
$template["style"] = "align: center";

// Un Assign a var
if (...) {
unset($template["welcome_text"]);
}

// Verify if a var was assigned
if (! isset($template["welcome_text"])) {
$template["welcome_text"] = $template["default_text"];
}

I like that Smile
