求高手解答smarty相关问题
我在smarty模板中导入了一个广告文件,但是我不知道这个广告文件是否存在,如果文件不存在的话会报错,怎样才能不报错啊,(注:我不想用assign传参,因为广告文件特别多,所以我不可能在php文件中一个一个去判断是否存在)
smarty模板中部分代码如下:
报错:
Warning: Smarty error: unable to read resource: "../../include/menu_tags_up_button.inc" in.....
如上述所述,如果"../../include/menu_tags_up_button.inc"文件不存在就会报错,当然,存在就什么问题都没有了,求高手解答啊[color=#FF00FF][/color]
------解决方案--------------------
你确定文件的路径是对的吗,程序既然说是无法读到文件,要不文件不存在,要不就是路径错了我嘛,还能是什么问题
------解决方案--------------------
你看到的smarty的报错,难道不是就是php的报错么??smarty抛出一个异常也是php来处理的呀,smarty不就是用php写的么??
如果想不报错,就设置php的display_error...之类的配置就好了呀。
------解决方案--------------------
你可以查看smarty手册,看有没有实现的方法,如果觉得麻烦,可以直接在模板中
嵌套php脚本
{php}
if(file_exists(path)){ include(path); }
{/php}
