本人小白,一直在公司用模板和框架写PHP,发现有时候连基本的sql语句都忘记了,所以有空想把PHP基础复习下,巩固下。分页和搜索,以及排序,还没写,后期继续更新...(代码修改:添加搜索和分页功能)
articlePublish.html:
- <meta http-equiv="Content-Type" content="text/html; charset=utf8">
- <title>Insert title here</title>
articlePublishDo.php:
- <?php
- header("content-type:text/html;charset=utf8");
- date_default_timezone_set('Asia/Shanghai');
- $title=trim($_POST['title']);
- $content=trim($_POST['content']);
- $time=date("y-m-d H:i:s");
- require_once 'init.php';
- $sql="insert into article(title,content,create_time) values('$title','$content','$time')";
- //echo $sql;
- $re=mysql_query($sql);//执行sql语句
- if($re){
- echo "发布成功";
- echo '返回文章列表';
- }else{
- echo "发布失败";
- echo '返回文章列表';
- }
- mysql_close();//关闭数据库
articleList.php:
- <meta http-equiv="Content-Type" content="text/html; charset=utf8">
- <title>Insert title here</title>
- <!--
- 搜索框
- -->
- <br>
- 返回发布文章
- <?php
- require_once 'init.php';
- /**
- * 搜索
- */
- $keyword=$_GET['search'];
- /*分页*/
- $sql="select count(*) from article where title like '%$keyword%' or content like '%$keyword%'";
- $res=mysql_query($sql);
- //$count= (int)mysql_num_rows($result);
- $arr=mysql_fetch_assoc($res);
- while(list($key,$val)=each($arr)){
- $count = (int)$val;
- }
- //echo $count;
- $pageSize=4;
- $page=floor($count/$pageSize)+1;//总页数$page
- echo $page;
- //echo $page;
- if(isset($_GET['page']))
- {
- //$currentPage = $_GET['page'];
- if($_GET['page'] <=1){
- $currentPage = 1;
- }elseif ($_GET['page'] >= $page){
- $currentPage = $page-1;
- }else{
- $currentPage = $_GET['page'];
- }
- }else
- {
- $currentPage=1;
- }
- $start = ($currentPage-1)*$pageSize;
- $sql="select id,title,content from article where title like '%$keyword%' or content like '%$keyword%' limit $start,$pageSize";
- //echo $sql;
- $re=mysql_query($sql);//执行sql语句
- while($arr=mysql_fetch_assoc($re)){
- ?>
- <?php
- }
- mysql_close();//关闭数据库
- ?>
- <table cellspacing="0" cellpadding="0" align="center" bgcolor="#ccc" width="500"><tbody><tr>
- <th>编号</th>
- <th>文章标题</th>
- <th>文章内容</th>
- <th>编辑文章</th>
- </tr><tr>
- <td align="center" style="border:1px solid #000"><?php echo $arr['id'];?></td>
- <input type="hidden" name="id" value="<?php echo $arr['id'];?>">
- <td align="center" style="border:1px solid #000"><?php echo $arr['title'];?></td>
- <td align="center" style="border:1px solid #000"><?php echo $arr['content'];?></td>
- <td align="center" style="border:1px solid #000">
- "><font color="red">修改</font>
- "><font color="red">删除</font>
- </td>
- </tr></tbody></table>
- 共<?php echo $page?>页 |查到<?php echo $count;?>条记录
- 当前第<?php echo $_GET['page']?>页|
- ">首页
- &search=<?php echo $keyword?>">|上一页
- &search=<?php echo $keyword?>">|下一页
- &search=<?php echo $keyword?>">|末页
articleEdit.php:
- <meta http-equiv="Content-Type" content="text/html; charset=utf8">
- <title>Insert title here</title>
- <?php
- $id=(int)$_GET['id'];
- require_once 'init.php';
- $sql="select id,title,content from article where id = '$id'";
- //echo $sql;
- $re=mysql_query($sql);//执行sql语句
- $arr=mysql_fetch_assoc($re);
- //var_dump($arr);
- mysql_close();//关闭数据库
- ?>
articleUpdate.php:
- <?php
- header("content-type:text/html;charset=utf8");
- $arr=$_POST;
- $id=(int)$arr['id'];
- require_once 'init.php';
- $sql="update article set title = '$arr[title]',content = '$arr[content]' where id = '$id'";
- //echo $sql;
- $re=mysql_query($sql);//执行sql语句
- //echo $re;
- if($re){
- echo "修改成功";
- echo "返回文章列表";
- }else{
- echo "修改失败";
- echo "返回文章列表";
- }
- mysql_close();//关闭数据库
articleDelete.php:
- <?php
- header("content-type:text/html;charset=utf8");
- require_once 'init.php';
- $id=(int)$_GET['id'];
- $sql="delete from article where id = '$id'";
- //echo $sql;
- $re=mysql_query($sql);
- if($re){
- echo "删除成功";
- echo "返回文章列表";
- }else{
- echo "删除失败";
- echo "返回文章列表";
- }
init.php:
- <?php
- //连接数据库
- //五步走
- //往数据库添加文章
- $conn=mysql_connect("localhost","root","");//链接数据库
- //echo $conn;
- $re=mysql_select_db("article");//选择数据库
- mysql_query("set names utf8");//设置交互字符集
基础知识总结:
文章发布系统
1.articlePublish.html 发布文章页面 提交到articlePublishDo.php页面,执行写入数据库
2.articleList.php 文章列表页面
3.点击编辑,修改文章 提交到 aiticleEdit.php 表单页面(回显)
4.点击修改文章按钮 提交到 articleUpdate.php
希望本文所述对大家的php程序设计有所帮助。
