问题描述
我有一个表单，它有两个组合框，每个框都包含yes，没有值。
如果两个框都是，那么在php上执行第1阶段代码
否则，如果一个框值=是，其他框值=否则在PHP代码上执行第1阶段
否则如果一个框值=否且其他框值=是然后在PHP代码上执行第1阶段
否则在php代码上执行第4阶段
但这总是执行第4阶段它没有得到值

i have a form and it has two combo boxes, each boxes are containing yes,no values.
if both boxes are yes then execute stage 1 on php code
else if one box value=yes and other box value = no then execute stage 1 on php code
else if one box value=no and other box value = yes then execute stage 1 on php code
else execute stage 4 on php code
but this always execute stage 4 it is not getting the values
