我如何将smartyBc添加到苗条框架

Question

我正在编写一个简单的苗条应用程序，想编写混合了smarty语法的原始php，但我一直收到以下错误。

Syntax error in template "./templates/application/header.tpl" on line 106 "{php}" unknown tag "php"

如果我像这样将tpl文件更改为{include_php}

  {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',
    'secret' => '1e12350dc6629a44df6b6771b6cb0cabd153aadc91f6af2697d371294296f69866b7c729a58b82108770ab02b087fda821af4533fe85b8115504ed9084055d77',
    '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';
require 'app/controllers/login.php';
require 'app/controllers/registration.php';



#require 'app/controllers/category_menu.php';


$app->run();

您不应该将PHP与Smarty混合使用，因此应该在PHP中做您需要的事情，并为Smarty分配价值。 然后，您根本不需要使用{php}标签。 Smarty用于显示数据，将php与Smarty混合使用使得使用Smarty没有多大意义。

但是，如果您确实需要在Smarty模板中使用php标签，则应该更改：

$app = new \Slim\Slim(array(
    'view' => new \Slim\Views\Smarty()
));

成

$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视图不存在于小型框架中，因此我们必须创建它

尽管我从未使用过Slim框架，但我还是决定进一步研究。 由于SmartyBC在Slim视图中不存在，因此我们必须手动创建它。

在Slim \\ Views目录中，您必须创建具有内容的SmartyBC.php文件：

class SmartyBC extends \Slim\View
{
    /**

                    throw new \RuntimeException('Cannot set the SmartyBC lib directory : ' . $this->parserDirectory . '. Directory does not exist.');

            $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;
    }
}

实际上，您只需从Smarty.php View复制内容，然后将所有Smarty更改为SmartyBC。 而已！

index.php应该看起来像：

<?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();

您不必像在代码中一样在此处手动添加SmartyBC.class.php。 当然，这只是示例和最少的代码（用于Slim Framework和添加的Smarty视图）。

模板文件：

{$test}, hello world and {php} echo "hello world from php"; {/php}

输出为：

User, hello world and hello world from php

因此正是您想要实现的目标。

但是，我提醒您，这不是将PHP与模板混合使用的最佳方法。 即使在Smarty文档中，您也可以阅读：

{php}标记已从Smarty中弃用，因此不应使用。 将您的PHP逻辑放入PHP脚本或插件函数中。
