Good Afternoon,
Just before I explain my problem with example code, allow me to briefly explain the file structure I currently have in place
../lib/_classes -> All Framework classes are here
../lib/_controllers -> All Framework controllers are here
../lib/_models -> All Framework models are here
../lib/_widgets -> All Widgets/site elements are here
../lib/Facebook -> Facebook library
../lib/Smarty -> Smarty library
Okay, so I have created a plug-in inside the ./Smarty/plugins/ directory, called widget (function.widget.php) this will basically look for a controller.php inside the ./lib/_widgets/<name>/controller.php and create an instance of this item.
My problem is when i parse the $smarty object into the Widget and then set variables, they appear in the list. When i display my view.tpl the variables are blank.
The Process: HTTPD -> Controller -> View -> ((Widget => Controller -> View))
Please see the source code below for further examples...
./themes/default/home/index.tpl
| Code: | {include file='../ob/inc.head.tpl' script_title="__TITLE__ | `$smarty.const.CONF_APP_NAME`" keywords='' description=''}
<div id="body">
<div id="leftcol">
<div class="lefttop"></div>
<div class="leftshadow">
<div class="left">
<h1 title="## TTL_HOME_WELCOME ##">## TTL_HOME_WELCOME ##</h1>
<p>## TXT_DEV_COMING_SOON ##</p>
{widget name='Test' param1='hello' param2='world'}
</div>
</div>
<div class="leftbtm"></div>
</div>
<div class="rightcol">
{include file='../ob/inc.blog-categories.tpl'}
</div>
<div class="rightcol">
{include file='../ob/inc.right.tpl'}
</div>
<div class="end"></div>
</div>
{include file='../ob/inc.footer.tpl'} |
./lib/Smarty/plugins/function.widget.php
| Code: | <?php
function smarty_function_widget($params, $smarty) {
if (empty($params['name']))
user_error('Widget is missing name.', E_USER_ERROR);
if (!file_exists($controller = sprintf('%s/controller.php', CONF_DIR_WIDGETS . strtolower($params['name']))))
user_error(sprintf('Cannot allocate widget (%s) controller.', $params['name']), E_USER_ERROR);
require_once ($controller);
$widget = call_user_func($params['name'] . '::factory', $params);
$widget->loadView($smarty)->execute();
} |
../lib/_classes/class.widget.php
| Code: | <?php
class Widget {
protected $smarty;
private $_vars = array();
final public static function factory($params = array()) {
$className = get_called_class();
return new $className($params);
}
final private function __construct($params) {
$this->_vars = $params;
unset($params, $this->_vars['name']);
}
final public function loadView($smarty) {
$this->smarty = $smarty;
$this->smarty->assign($this->_vars); // when var dump here, this returns the vars i require
return $this;
}
final public function display() {
$className = strtolower(get_called_class());
var_dump($this->smarty->getTemplateVars()); // this returns the vars i require!
$this->smarty->display(CONF_DIR_WIDGETS . $className . '/view');
}
public function execute() {
return $this->display();
}
} |
../lib/_widgets/test/controller.php
| Code: | <?php
class Test extends Widget {} |
../lib/_widgets/test/view.tpl
| Code: | <div style="background: #f00; padding: 10px;">
{$param1} __ {$param2} <!-- this is where the vars do not appear at all! -->
</div> |
If anyone could help i'd much appreciate it. |

Note that in Smarty 3 the second parameter of plugins is no longer the Smarty object but the template object.
| Code: | <?php
function smarty_function_widget($params, $template) {
if (empty($params['name']))
user_error('Widget is missing name.', E_USER_ERROR);
if (!file_exists($controller = sprintf('%s/controller.php', CONF_DIR_WIDGETS . strtolower($params['name']))))
user_error(sprintf('Cannot allocate widget (%s) controller.', $params['name']), E_USER_ERROR);
require_once ($controller);
$widget = call_user_func($params['name'] . '::factory', $params);
$widget->loadView($template->smarty)->execute();
} |
Not 100% sure if this caused the problem.
I think
$this->smarty->display(CONF_DIR_WIDGETS . $className . '/view');
is a typo and should be
$this->smarty->display(CONF_DIR_WIDGETS . $className . '/view.tpl'); |

Thanks, I totally forget in Smarty 3, that $smarty (aka $template) was NOT the smarty object, but actually the template object (containing the smarty instance).
your solution was infact the answer to my problem, thanks.
Finally, I extended the Smarty class with my own Template class and overridden some methods such as the display to automatically append.tpl to the end of the templates (solely because i will NOT use php templates as i love the smarty syntax).
Cheers! |
