一、代码

1、sql

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 -- phpMyAdmin SQL Dump -- version 4.5.1 -- http://www.phpmyadmin.net -- -- Host: 127.0.0.1 -- Generation Time: 2022-03-19 19:16:40 -- 服务器版本：10.1.13-MariaDB -- PHP Version: 5.6.21 SET SQL_MODE = "NO_AUTO_VALUE_ON_ZERO" ; SET time_zone = "+00:00" ; /*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */; /*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */; /*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */; /*!40101 SET NAMES utf8mb4 */; -- -- Database: `a` -- -- -------------------------------------------------------- -- -- 表的结构 `search` -- CREATE TABLE `search` ( `id` int (20) NOT NULL , `content` text COLLATE utf8_vietnamese_ci NOT NULL , `type` varchar (100) COLLATE utf8_vietnamese_ci NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE =utf8_vietnamese_ci; -- -- 转存表中的数据 `search` -- INSERT INTO `search` (`id`, `content`, `type`) VALUES (32, 'aaa' , '特步' ), (33, '陈业贵喜欢安踏' , '安踏' ); -- -------------------------------------------------------- -- -- 表的结构 `type` -- CREATE TABLE `type` ( `id` int (11) NOT NULL , `type` varchar (12) COLLATE utf8_vietnamese_ci NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE =utf8_vietnamese_ci; -- -- 转存表中的数据 `type` -- INSERT INTO `type` (`id`, `type`) VALUES (1, '安踏' ), (2, '特步' ); -- -- Indexes for dumped tables -- -- -- Indexes for table `search` -- ALTER TABLE `search` ADD PRIMARY KEY (`id`); -- -- Indexes for table `type` -- ALTER TABLE `type` ADD PRIMARY KEY (`id`); -- -- 在导出的表使用AUTO_INCREMENT -- -- -- 使用表AUTO_INCREMENT `search` -- ALTER TABLE `search` MODIFY `id` int (20) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=34; -- -- 使用表AUTO_INCREMENT `type` -- ALTER TABLE `type` MODIFY `id` int (11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=3; /*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */; /*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS */; /*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */;

2、列表页(index.php)

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 <?php $link =mysqli_connect( 'localhost' , 'root' , '' , 'a' ); //然后是指定php链接数据库的字符集 mysqli_set_charset( $link , 'utf8' ); $sql = "select * from search" ; //模糊查询出像数据库中的title或者content里面的值或者说像数据库中的title或者content里面的某一段值相对应的就行了,就可以输出啦 $result =mysqli_query( $link , $sql ); //运行sql ?>  <!DOCTYPE html> <html lang= "en" > <head> <meta charset= "UTF-8" > <title>Document</title> </head> <body> <table border= "1" cellpadding= "5" > <tr> <td>id</td> <td>种类</td> <td>物品</td> <?php while ( $row =mysqli_fetch_array( $result )) { //把对象编程数组输出，不然会报错哦 # code... ?> <tr> <td><?= $row [ 'id' ];?></td> <td><?= $row [ 'content' ];?></td> <td><?= $row [ 'type' ];?></td> <td><a href= "update.php?id=<?php echo $row['id']; ?>" rel= "external nofollow" >更新</a></td> <td><a href= "delete.php?id=<?php echo $row['id']; ?>" rel= "external nofollow" >删除</a></td> </tr> <?php } ?> </tr> </table> <a href= "create.php" rel= "external nofollow" >创建</a> </body> </html>

3、delete.php

1 2 3 4 5 6 7 8 9 10 <?php $link =mysqli_connect( 'localhost' , 'root' , '' , 'a' ); //然后是指定php链接数据库的字符集 mysqli_set_charset( $link , 'utf8' ); //$sql = "DELETE FROM `search` WHERE `id` = '$_POST[id]'"; //模糊查询出像数据库中的title或者content里面的值或者说像数据库中的title或者content里面的某一段值相对应的就行了,就可以输出啦 $result =mysqli_query( $link , "DELETE FROM search WHERE id ='$_GET[id]'" ); //运行sql echo "<script>alert('恭喜你，删除成功了');location.href='index.php';</script>" ; ?>

4、update.php

5、create.php
