在symfony中使用数据库存储cache

 Symfony  2 Responses »
八 142007

Symfony默认使用文本格式存储cache，另外还可以选择SQLite来存储cache，这样简单的数据库系统对存储cache来说效率非常高。
打开factories.yml文件，设置一下参数。

view_cache:
class: sfSQLiteCache
param:
database: %SF_TEMPLATE_CACHE_DIR%/cache.db

如果原来的系统大量的使用了cache，不妨改为SQLite为cache的存储，性能可能会有所改善哦。

symfony使用cookie来实现自动登录

 Symfony  2 Responses »
七 032007

简单来说就是登录时实现一个记住密码的功能。

在登录验证中，处理是否需要自动登录功能

  1. class myLogonValidator extends sfValidator
  2. {
  3.   public function initialize ($context, $parameters = null)
  4.   {
  5.     // initialize parent
  6.     parent::initialize($context);
  7.  
  8.     // set defaults
  9.     $this->getParameterHolder()->set('login_error', 'Invalid input');
  10.  
  11.     $this->getParameterHolder()->add($parameters);
  12.  
  13.     return true;
  14.   }
  15.  
  16.   public function execute (&$value, &$error)
  17.   {
  18.  
  19.     $autologon_cookie_param     = $this->getParameterHolder()->get('autologon_cookie');
  20.     $autologon_cookie            = $this->getContext()->getRequest()->getParameter($autologon_cookie_param);   
  21.     $username = $value;
  22.  
  23.   if ( $autoexit_cookie )
  24.    sfContext::getInstance()->getResponse()->setCookie('autologon_cookie', '', time()-3600, '/');
  25.   else 
  26.     sfContext::getInstance()->getResponse()->setCookie('autologon_cookie', $username, time()+2592000, '/');
  27.   return true;
  28. }

这里如果用户选择了自动登录，那么把$username保存到autologon_cookie中

验证数据库的某个字段是否已经存在了相同的数据

首先，在lib目录建立一个 sfCustomUniqueValidator.php

  1. < ?php
  2.   /**
  3. * sfCustomUniqueValidator checks if a record exist in the database with all the mentionned fields.
  4. *
  5. * ex: Check if a companie with company_name exist in country_id
  6. *   class:            sfCustomUniqueValidator
  7. *   param:
  8. *     class:          Companies    //the class on which the search is performed
  9. *     nb_fields:      2            //the number of fields on which the comparison is done
  10. *     field_1:        company_name //First field of the comparison
  11. *     field_2:        country_id   //Other country for the comparison
  12. *
  13. * @package    lib
  14. * @author     Joachim Martin
  15. * @date       15/06/2007
  16. */

  18. class sfCustomUniqueValidator extends sfValidator {

在玩儿一些程序的时候发现，用浏览器访问和用手机访问同一个网站会出现不同的界面，比如：v2ex

symfony可以通过Filter来实现这个功能：
