-->a+b:<br>
a/c:<br>
(a+b)/c:<br>
Copy after login


以上是程序和模板。
要怎么做才可以实现(a+b)/c?

------解决方案--------------------
你应该尽量在php中运算。再assign给模板。

另外。你的代码有什么错?
------解决方案--------------------
提示什么错误? php完全可以把各结果得到了再传给smarty。不就是多几个变量或是数组的问题。
------解决方案--------------------
看看这篇博文
------解决方案--------------------
加括号把,由于没有smarty环境。测试不了。看其他朋友怎么说。

{* $height=4, $width=5 *}
{math equation="x + y" x=$height y=$width}
OUTPUT:
9
{* $row_height = 10, $row_width = 20, #col_div# = 2, assigned in template *}
{math equation="height * width / division"
height=$row_height
width=$row_width
division=#col_div#}
OUTPUT:
100
{* you can use parenthesis *}
{math equation="(( x + y ) / z )" x=2 y=10 z=2}
OUTPUT:
6
{* you can supply a format parameter in sprintf format *}
{math equation="x + y" x=4.4444 y=5.0000 format="%.2f"}
