PHP 制作通讯录（五）

通讯录已经大致完成了，但如果记录数多时，查找起来很不方便，如果加一个搜索功能就好了。今天我们就来制作一个搜索功能

在Index.php合适的地方加入搜索框

 <!---搜索框--->
<!--这里的所有值前面加前缀“S_”以区分-->
<form />
  </label>
</form>

新建一个新的PHP文件，保存为Search.php

<?php include ('Config.php'); $word = $_POST['S_word']; //搜索关键字 $mode = $_POST['S_mode']; //搜索方式 switch($mode) { case 'S_all': $sql = 'SELECT * FROM `'.SqlDataBase.'`.`'.SqlTableName."` WHERE `Name` LIKE '%$word%' OR `Birthday` LIKE '%$word%' OR `QQ` LIKE '%$word%' OR `Mobile` LIKE '%$word%' OR `Email` LIKE '%$word%' OR `Address` LIKE '%$word%'";break; case 'S_name': $sql = 'SELECT * FROM `'.SqlDataBase.'`.`'.SqlTableName."` WHERE `Name` LIKE '%$word%'"; break; case 'S_birthday': $sql = 'SELECT * FROM `'.SqlDataBase.'`.`'.SqlTableName."` WHERE `Birthday` LIKE '%$word%'"; break; case 'S_qq': $sql = 'SELECT * FROM `'.SqlDataBase.'`.`'.SqlTableName."` WHERE `QQ` LIKE '%$word%'"; break; case 'S_mobile': $sql = 'SELECT * FROM `'.SqlDataBase.'`.`'.SqlTableName."` WHERE `Mobile` LIKE '%$word%'"; break; case 'S_email': $sql = 'SELECT * FROM `'.SqlDataBase.'`.`'.SqlTableName."` WHERE `Email` LIKE '%$word%'"; break; case 'S_address': $sql = 'SELECT * FROM `'.SqlDataBase.'`.`'.SqlTableName."` WHERE `Address` LIKE '%$word%'"; break; } require ('Conn.php'); ?>

然后就读出数据，可以参考Index.php中的源码，这里实现了一个比较简单的搜索功能，主要是SQL语句构造有点麻烦
