php投票问题，请问这个语法有什么错误？

[韦某一笑]

<?php if(pj1=="great"){
pj_result.Fields.Item("1_A").Value++;}
else if(pj1=="agree"){
pj_result.Fields.Item("1_B").Value++;}
else(pj1=="oppose"){
pj_result.Fields.Item("1_C").Value++;}
?>

pj1是三个单选按钮的名称，三者的值为great　agree oppose，现在我想如果选great，那么表pj_result下的字段1_A就自动加1；同理选agree，则1_B自动加1；选oppose，则1_C自动加1。
请问应该怎么改？

你想做的是自动加1的操作，这对于PHP而言并非长项。你可以使用数据库先读取库中已有值，而后再加1后写入数据库中，当然最好还是在前端计算great、agree、oppose的总数再统一写入数据库中。

小弟新手，不过觉得你这个问题不难啊。 其思路是： 1.判断 great， agree,oppose三种状态； 2. 相应值加1； 3. 从数据库读出相应字段的值，并赋值到某变量上； 4. 把该变量自动加1； 5. 把该变量的值再写入相应字段中，update一下即可。 难道不是么？求指导。

把那个页面的代码贴一下

已经贴出该页面的PHP语法及数据表结构。麻烦帮我看看，谢谢了！

[瞧俺老孙的]

pj_result.Fields.Item("1_C").Value++; 这么写不行吧。 你确定你的结果集可以这么操作？ 然后还能更新到数据库里面？
