使用PHP4中的 IntegratedTemplate类实现BLOCK功能
使用PHP 模板类进行编程很有好处,但是有时也会碰到一个问题,比如说输出一个表格,但是表格行数要到运行的时候才知道,如留言板、BBS、购物网站之类,经常会碰到这个问题。这时做美工的人无法决定在HTML文件中用几行表格,如果在PHP代码文件中写循环输出,又会让美工、PHP程序员看代码都不方便,美工的人会说,这里的表格哪里去了?我要修改表格的颜色背景之类怎么办?PHP程序员也会说,怎么这里突然有一个
使用PHP模板类编程一般把这种不确定个数的HTML 元素当成一个“ block ”,对 bolck 的编程类似于在代码中写一个循环。在比较常用的PHP模板类(如 FastTemplate 和 PHPLib )都有这种功能。写嵌套的block 类似于写多重循环。现在举例说明在 PHP4 里面的 IntegratedTemplateExtension 类中block 的编程方法,例子中用的是两重循环,外层block 是GoodsList,里层block 是GoodsListOfSomeType 。
基本设置:假设我们写的代码放在C:TestPHPPHP4GoodsList.htm 和 C:TestPHPHTMLGoodsList.php 中。将C:TestPHPPHP4 在Web Server 上设成虚拟目录 /testphp 并且给与脚本执行权限,确认C:TestPHPHTMLGoodsList.htm 无法通过远端浏览器访问。假定PHP4安装在C:php4,在 php.ini 里面设置 include_path = ".;C:php4pear"
以下是GoodsList.htm的内容:
