smarty自定义实现局部不缓存问题
使用插件block 法

  在Smarty/plugins目录下建一个文件block.nocache.php 内容如下:

 

         function smarty_block_nocache($param, $content, $smarty)  
    {  
          return $content;   
    }    
    ?>

在模板中(smarty已经配置成功):

    {nocache}  
    不缓存的内容,如:{$smarty.now}  
    {/nocache} 

按照上面的配置,nocache块包含的内容应该是时时更新的
为什么在mvc模式下使用时,不能时时更新呢?
------最佳解决方案--------------------
我记得smarty里面有个insert 是动态加载,不走缓存的吧

------其他解决方案--------------------
一、以插件形式

    指定该函数的名称,如:nocache。然后到plugins这个文件下建立块函数。(./plugins/block.nocache.php)命名文件的名字的时候要遵循自定义函数的要求。我们要在这个函数里把每次请求出来的部分内容显示出来,不让它生成缓存:


   function smarty_block_nocache($args, $content){

     return $content;}

?>

       在smarty里面所有的插件默认被缓存。所以这个文件也会被缓存。这时我们要修改Smarty_Compiler.class.php这个配置文件,在文件的712行的位置上会:“                 $this->_plugins['block'][$tag_command] = array($plugin_func, null, null, null, true); 。”这里把括号里面的true改成false,这样所有的插件就不会被自动生成缓存。如果我们不想把所有的插件都改成不被缓存的状态,只想我把写的block.nocache.php这个文件不被缓存。

if($tag_command==nocache){

$this->_plugins['block'][$tag_command] = array($plugin_func, null, null, null, false);}

Else{

$this->_plugins['block'][$tag_command] = array($plugin_func, null, null, null, true);


这样问题解决,谢谢大家

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
