You shouldn't mix PHP with Smarty so you should do what you need in PHP and assign value to Smarty. Then you won't need to use {php} tag at all. Smarty is for displaying data and mixing php with Smarty makes that using Smarty doesn't make much sense.
However if you really need to use php tag in Smarty template you should change:
$app = new \Slim\Slim(array(
'view' => new \Slim\Views\Smarty()
));
into
$app = new \Slim\Slim(array(
'view' => new \Slim\Views\SmartyBC()
));
but I really don't recommend using php inside Smarty templates
EDIT - SMARTYBC VIEW DOESN't EXISTS IN SLIM FRAMEWORK SO WE HAVE TO CREATE IT
Although I've never used Slim framework I've decided to look further. As SmartyBC doesn't exists in Slim views, we have to manually create it.
In the Slim\Views directory you have to create SmartyBC.php file with content:
<?php

In fact you simple have to copy content from Smarty.php View and change all Smarty to SmartyBC. That's it!
The index.php should look like:
<?php
require 'Slim/Slim.php';
\Slim\Slim::registerAutoloader();
$app = new \Slim\Slim(array (
'view' => new \Slim\Views\SmartyBC()
)
);
$view = $app->view();
$view->parserDirectory = dirname(__FILE__) . '/smarty';
$view->parserCompileDirectory = dirname(__FILE__) . '/compiled';
$view->parserCacheDirectory = dirname(__FILE__) . '/cache';
$view->setTemplatesDirectory(dirname(__FILE__) . '/smarty/templates');
$app->get(
'/',
function () use ($app) {
$app->render('index.tpl', array('test' => 'User'));
}
);
$app->post(
'/post',
function () {
echo 'This is a POST route';
}
);
$app->put(
'/put',
function () {
echo 'This is a PUT route';
}
);
$app->patch('/patch', function () {
echo 'This is a PATCH route';
});
$app->delete(
'/delete',
function () {
echo 'This is a DELETE route';
}
);
$app->run();
You don't have to include here manually SmartyBC.class.php as you did in your code. Of course this is only sample and minimal code (used from Slim Framework and added Smarty view).
Template file:
{$test}, hello world and {php} echo "hello world from php"; {/php}
Output is:
User, hello world and hello world from php
so exactly what you wanted to achieve.
However I remind you that's not the best way to mix your PHP with templates. Even in Smarty documentation you can read:
{php} tags are deprecated from Smarty, and should not be used. Put
your PHP logic in PHP scripts or plugin functions instead.
