【问题描述】：
我有一个表格，用户可以在其中注册俱乐部的个人信息，并将其存储在数据库中。一切正常，包括 MySQL。 但是，我的搜索功能有问题。搜索页面应该是粘性形式。 用户应该能够搜索并显示结果......就像他们在搜索框中输入名字或姓氏......然后结果显示数据库中满足特定条件的所有信息 谁能帮我修复我的搜索功能所有页面代码都在下面给出...... 谢谢！！！
这是我的表单页面代码.....

【问题讨论】：
-
我没有给出我的编辑和删除代码..因为..我认为这不是必需的
-
搜索功能有问题 但是您遇到的问题是什么？ [:-(]
-
1. $sql="SELECT * FROM members WHERE FirstName=" 。 $f名称; => 只匹配一个完整的名字，如果它是一个搜索，你可能想要使用 like 并包含更多字段，然后只是名字。 2.你有一个回声“”；在您的 -tag 中，这不是放置它的正确位置
-
谁来扫码？？请告诉我们问题出在哪里并删除不需要的代码
-
当我在搜索框中输入任何名称时..没有显示
