另外也补充问个问题
我用SMARTY自己做 modifier.xxx.php 这类插件时,平时是常想顺利的
但为什么一用到数据库就完全不行?
我是用PDO的
因为没把$pdo这类句柄传入? 但是这种插件是由 模板直接调用,我根本就不能加入$pdo
我也试过加插件的function 内引入数据库文件,但也是表示数据库操作有误
请问有什么解决方案吗? 还是插件这部分根本不能操作数据库???
哪一步没成功?$row_type没值吗?
1.通过模板处理:类表 关联 子类表 得出结果集,在进行smarty的assign,模板循环2次 。
2.通过程序查询结果集处理:返回结果集,在程序组装成为字符串,直接assign传到模板。
