PHP Form的疑问?
[复制链接]

请各位高手给我一些Ideas，好吗？万分感激！！！
1. 我要如何在输入Quanlity时，只限于号码。例如不允许4r，78y等；且忘记输入时不会补零。当输入正确时，例如 1，83，下一页会显示001，083。
2.我想在Form里设计多个资料栏一起传送，例如在线底下加如新的Name,Hobby,Sex和Quantity。但我希望当用户输入第二行的资料栏时，只要Name有值，就必须做Validation;反之，当第二行的Name无值，无论其它的资料栏有值或无值，就ignore他。
希望各位理解我想表达的，且尽量帮帮我，谢谢！

我是在完全没有看你的代码下发表我的看法的.（我懒惰）
1. 用Javascript检查，如果输入正确，检查字串长度，
如果不足3就在前面加0.
2. 用检查字串长度，如果字串长度 = 0，就ignore，如果不是就检查. |
