Smarty - the compiling PHP template engine | ||

Smarty allows access to PHP objects through the templates. There are two ways to access them. One way is to register objects to the template, then use access them via syntax similar to custom functions. The other way is to assign objects to the templates and access them much like any other assigned variable. The first method has a much nicer template syntax. It is also more secure, as a registered object can be restricted to certain methods or properties. However, a registered object cannot be looped over or assigned in arrays of objects, etc. The method you choose will be determined by your needs, but use the first method whenever possible to keep template syntax to a minimum.
SMARTY允许通过模板访问PHP对象。有两种方式来访问它们。一种是注册对象到模板,然后通过类似于用户自定义函数的形式来访问它。另一种方法给模板分配对象,然后通过访问其它赋值变量类似的方法进行访问。第一种方法有一个很好的模板语法,同时它作为一个注册对象被限制为几个固定的方法和目标,这样是比较安全的。然而一个注册对象不能够在相对自身数组里面循环使用和赋值。总之,你根据你自己的需求来觉得选用那种方法,但是使用第一种方法的话,可以让你的模伴语法达到最小。
If security is enabled, no private methods or functions can be accessed (begininning with "_"). If a method and property of the same name exist, the method will be used.
如果安全选项激活后,就没有私有成员或者函数能够被访问(以"_"开头)。如果有一个同名成员或者对象存在,那么方法将被使用。
You can restrict the methods and properties that can be accessed by listing them in an array as the third registration parameter.
你可以限制成员和函数,但是外解可以通过列举它们为一个第三注册变量的数组的方式来访问它。
By default, parameters passed to objects through the templates are passed the same way custom functions get them. An associative array is passed as the first parameter, and the smarty object as the second. If you want the parameters passed one at a time for each argument like traditional object parameter passing, set the fourth registration parameter to false.
一般情况下,参数通过模板传递给对象的方法和自定义函数获得参数的方法是一样的。一个混合数组作为第一个参数传递,而SMARTY对象作为第二个。如果你想像传统的对象参数一样一次传递一个参数,设置第四个参数为 FALSE即可。
