我正在编写一个简单的超薄应用程序，并希望编写原始的PHP混合巧妙的语法，但我不断收到以下错误。
Syntax error in template "./templates/application/header.tpl" on line 106 "{php}" unknown tag "php"
如果我将我的tpl文件更改为{include_php}，就像这样
{include_php}
<?php echo 'home ' ?>
{/include_php}
我收到以下错误，
Type: SmartyException
Message: {include_php} is deprecated, use SmartyBC class to enable
File: /home/ramza/apps/php/company/Smarty/sysplugins/smarty_internal_compile_include_php.php
Line: 52
我的苗条 index.php 如下：
<?php
session_cache_limiter(false);
session_start();
require 'vendor/autoload.php';
require 'vendor/php-activerecord/ActiveRecord.php';
require_once('Smarty/SmartyBC.class.php');
ActiveRecord\Config::initialize(function($cfg) {
$cfg->set_model_directory('models');
$cfg->set_connections(array(
'development' => 'mysql://root:@localhost/xxx'
));
});
require 'models/OcMember.php';
$app = new \Slim\Slim(array(
'view' => new \Slim\Views\Smarty()
));
$view = $app->view();
$view->parserDirectory = dirname(__FILE__) . 'Smarty';
$view->parserCompileDirectory = dirname(__FILE__) . '/compiled';
$view->parserCacheDirectory = dirname(__FILE__) . '/cache';
$view->parserExtensions = array(
dirname(__FILE__) . '/vendor/slim/views/Slim/Views/SmartyPlugins',
);
$app->add(new \Slim\Middleware\SessionCookie(array(
'expires' => '20 minutes',
'path' => '/',
'domain' => null,
'secure' => false,
'httponly' => false,
'name' => 'slim_session',

'cipher' => MCRYPT_RIJNDAEL_256,
'cipher_mode' => MCRYPT_MODE_CBC
)));
$authenticate = function ($app) {
return function () use ($app) {
if (!isset($_SESSION['company_id'])) {
$_SESSION['urlRedirect'] = $app->request()->getPathInfo();
$app->flash('error', 'Login required');
$app->redirect('/company/login');
}
};
};
$app->hook('slim.before.dispatch', function() use ($app) {
$current_company = null;
if (isset($_SESSION['company_id'])) {
$current_company = Company::find($_SESSION['company_id']);
}
$app->view()->setData('current_company', $current_company);
});
require 'app/controllers/before_filters.php';
require 'app/controllers/members.php';

你不应该将PHP与Smarty混合，所以你应该在PHP中做你需要的并为Smarty赋值。然后你根本不需要使用{php}标签。 Smarty用于显示数据并将PHP与Smarty混合使得使用Smarty没有多大意义。
但是如果你真的需要在Smarty模板中使用php标签，你应该改变：
$app = new \Slim\Slim(array(
'view' => new \Slim\Views\Smarty()
));
到
$app = new \Slim\Slim(array(
'view' => new \Slim\Views\SmartyBC()
));
但我真的不建议在Smarty模板中使用php
编辑 - SMARTYBC视图不会出现在SLIM框架中，因此我们必须创建它
虽然我从未使用过Slim框架，但我决定进一步研究。由于SmartyBC在Slim视图中不存在，我们必须手动创建它。
在Slim \ Views目录中，您必须创建包含内容的SmartyBC.php文件：
<?php

*/
class SmartyBC extends \Slim\View
{
/**
* @var string The path to the Smarty code directory WITHOUT the trailing slash
*/
public $parserDirectory = null;
/**

public function render($template, $data = null)
{
$parser = $this->getInstance();
$parser->assign($this->all());
return $parser->fetch($template, $data);
}
/**

public function getInstance()
{
if (! ($this->parserInstance instanceof \SmartyBC)) {
if (!class_exists('\SmartyBC')) {
if (!is_dir($this->parserDirectory)) {
throw new \RuntimeException('Cannot set the SmartyBC lib directory : ' . $this->parserDirectory . '. Directory does not exist.');
}
require_once $this->parserDirectory . '/SmartyBC.class.php';
}
$this->parserInstance = new \SmartyBC();
$this->parserInstance->template_dir = $this->getTemplatesDirectory();
if ($this->parserExtensions) {
$this->parserInstance->addPluginsDir($this->parserExtensions);
}
if ($this->parserCompileDirectory) {
$this->parserInstance->compile_dir = $this->parserCompileDirectory;
}
if ($this->parserCacheDirectory) {
$this->parserInstance->cache_dir = $this->parserCacheDirectory;
}
}
return $this->parserInstance;
}
}
事实上，您只需要从Smarty.php查看内容并将所有Smarty更改为SmartyBC。就是这样！
index.php应如下所示：
<?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';
}
);
$app->run();
您不必像在代码中那样手动包含SmartyBC.class.php。当然，这只是示例和最小代码（从Slim Framework使用并添加了Smarty视图）。
模板文件：
{$test}, hello world and {php} echo "hello world from php"; {/php}
输出是：
User, hello world and hello world from php
正是你想要实现的目标。
但是我提醒你，这不是将PHP与模板混合的最佳方式。即使在Smarty文档中，您也可以阅读：
{php}标签已从Smarty弃用，不应使用。放 PHP脚本或插件函数中的PHP逻辑。
