Smarty - the compiling PHP template engine | ||

When the template is invoked via display() or fetch(), its output can be sent through one or more output filters. This differs from postfilters because postfilters operate on compiled templates before they are saved to the disk, and output filters operate on the template output when it is executed.
当模板通过函数 display() 或者 fetch()被调用时,它的输出能够通过一个或者多个滤镜而发出。 它与预过滤器的不同之处就是预过滤器编译模板是在模板保存到磁盘之前,输出滤镜是在它执行的时候才操作模板输出的。
Output filters can be either registered or loaded from the plugins directory by using load_filter() function or by setting $autoload_filters variable. Smarty will pass the template output as the first argument, and expect the function to return the result of the processing.
输出滤镜同样能够通过 load filter() 函数和设置 $autoload filters 变量来注册或者从工具目录里载入。SMARTY将传递模板输出作为第一个参数,通过自定义函数返回处理结果。
