PHP前后端交互 | web文章博客

前言
环境部署
总结

前言

一、项目需求；
做个基础的页面，文章博客web应用实现后台交互；
二、项目模块与技术；
PHP实现web文章博客前后端交互全过程：GET、POST、AJAX请求
页面渲染交互包括前端三剑客（html，css，JavaScript）
CSS包括接入模式及嵌入模式
此web程序，引用jQuery库，html及php、与混合模式
session，cookie校验等，防前端绕过通过url请求参数获取网页
form表单提交，Ajax提交
共有六种页面，注册页面，登录页面，编辑页面，发表页面，列表页面，详情页面
文本框，用户名框，密码框，标题框，文件提交，注册按钮，登录及注销按钮
服务器数据库后台交互、保存用户信息等

界面不好看勿喷、仅基础后台交互技术方向
（本人网安人，前端与后端开发大佬多多指点）栓Q。

一、登录

“!+Enter” html框架自动列出、title标签写个网页名
style标签里写css样式、博主就记住两个"#“开头引用时用id=，”."开头用class=
这里介绍下css样式嵌入式用法、后面页面不过多介绍了；

border: 0px solid blue;//边框蓝色:调试完成后写0隐藏width: 500px;//宽度height: 450px;//高度margin: auto;//左右边界相等，居中text-align: center;//文本框半隐字体居中font-size: 18px;//字体大小color:rgb(161, 18, 177);//直接用color是设置字体颜色，三个数字是调色板border: 1px solid red; //边框1px粗、红色边框margin-top: 30px;//上边距30px距离margin-left: 30px;//左边距30px距离resize: none;//禁止大文本框拉调color: blueviolet;//字体：颜色background-image: url('black-star.jpg');    //网页背景引入图片

效果图：（前面sql语句中插入过一条用户可登录）
在这里插入图片描述

二、注册

关键思路流程点
前端regist.html、后端regist.php
实现前端后端分离
注册按钮doRegist()触发自定义函数
前端处理获取数据，数据组包
文件特殊；用内置函数prop()获取元素的属性值
var dt=new FormData();实例化对象，文件上传表单提交
组装数据，组好接口参数
发送Ajax请求组好头部必写项
success:前面执行成功则执行后面代码，否则不执行(细节)
与后端数据进行if判断比较data与后端反馈结果regist-pass相同返回则注册成功。
前端代码如下；

$_POST $_FILES 收集表单
收集表单时注意定义文件路径、需要在服务器创建保存头像的文件夹
注意提升文件夹写入权限~
我的路径是’ [root@centos7 upload]# pwd
/opt/lampp/htdocs/safe14/blog/upload ’
数据非空校验if判断
后面判断服务器是否收到文件，如果没收到文件，直接终止执行注册。确保服务器不背锅
操作数据库；
include //引用db.php文件
定义后台sql语句，定义结果(dml调用当前sql语句变量)如果后台变量sql语句执行成功)
成功插入用户注册数据返回结果为1，当返回结果等于1时，echo个’regist-pass’否则失败
dml 是db.php文件中定义好的自定义函数
dml函数中写法是连接数据库代码，设好utf8编码集。
注册后端代码如下；

在这里插入图片描述

db.php，数据库操作文件；
mysqli_connect //内置连接函数
用 mysqli_query 设置字符编码及、先把连接放前面进行设置utf8
定义结果函数，暂定个空sql查询函数留作后调用。

三、主页

注销；删除；发表；编辑；注销；
思路流程；
style标签弄点css样式渲染按钮图标
引用jQuery库
单机调用do_die()函数；用来注销用户
单机调用doDel(id)函数；用来删除文章
开启服务器session校验session_start();
include ‘db.php’;引入数据库操作，将数据库所有的值取出来，用foreach遍历，echo出来div盒子，盒子中放填变量，及单机击触发某函数事件，触发功能。
这里简单仍外面两个div一个发表一个注销
单机发表跳转另一个页面，在新的页面里发表文章上传至数据库、编辑也是，跳转至编辑后台进行处理编辑结果
不仍里面的原因，懒得调整css样式，仍里面会将里面内容乱挤
大的div 样式选择out，将第一排的列头先放进去。

四、详情

用法及思路
主页用的a标签链接过来url添加请求参数(变量$id)获取详情页内容；
这里用了link标签 href接入式CSS;
fieldset标签组合表单相关的元素里面一个大div、放一堆小div;
因此后台是".php"文件。可以写html与php混合写，html文件却不能写php代码
在fieldset里面写;
引用数据库，用db文件里的select函数查询sql语句返回的结果，用变量定义用下标0取值
@是防止输入不存在的id号时展示文章内容出现报错，报错信息会暴漏服务器位置，所以用@直接屏蔽，且不展示任何内容值。
上面还用get请求出id内容，用id定义变量
下面的标签看似复杂其实简单粗暴加偷懒；
放过p标签里面写php代码将标签变量内容echo出来，作者及发表事件同样用php代码echo出来
textarea标签（长文本标签）同样echo出来content
下面再放过a标签返回列表路径
完成详情页面

五、编辑

按钮：编辑/保存与返回
思路及流程；
接入式CSS；引用jQuery库；
'编辑’按钮触发函数，返回按钮超链接；
详细内容输出参照详情页面输出出来；引用数据库select函数同理
注意：不通的是标题用text标签，为了可修改
session校验，防止未登录过的用户前端绕过，url请求参数访问编辑页面。
编辑且保存调用doEdit(id)；
var定义一些数据用content收集起来打包
发送post请求；
后端执行sql修改语句，用if语句作判断前后端data内容如果后端执行成功返回edit-pass一致弹出编辑成功，反之，编辑失败。

六、删除

方法
回查主页代码中的删除按钮使用方法如下；
div盒子单击触发事件，调用函数doDel()；
用id收集取值，发送post请求
调用del.php后台，后台执行删除sql语句，前后端data用if判断返回结果success，前后端一致则成功，反之删除失败。
下方删除了部分与删除无关的代码；

七、注销

方法
回查主页代码中的注销按钮使用方法如下；
div盒子单击触发事件，调用函数do_die()；
非常简单就一个逻辑，单机注销按钮后，直接跳转注销后台(doDot.php)，处理注销。
下方删除了部分与注销无关的代码；

开启会话校验，将isLogin直接关掉（这里isLogin是布尔值型，只有开和关session）

八、发表

思路及方法
回看主页代码中的发表按钮使用方法如下；
主页面代码单击发表div盒子就一个跳转链接，链接地点：doblog.html
下面是发表前端代码；
接入式CSS；引用jQuery库
大div里放个标题text与textarea，和一个发表按钮
单机按钮触发doAdd()自定义函数
准备数据：定位，获取，拼装URL编码，post请求及前后端data比较
if判断，后端发表成功返回add-pass，与前端一致则发表成功，反之发表失败。
发表成功后跳转至主页。

手敲报错信息排查方法：
1、查找多写少些字符，标点符号使用规范；
2、出现代码执行成功，或数据写入成功，却反向报错失败。检查php代码结尾的?>下方是否有回车，有则应当清空；
3、如页面无任何反应，无报错信息，应当地毯式从头到尾用echo或alert打印、弹出排查代码执行结果；
4、如无响应，无跳转，可浏览器F12查看network网络及控制台等等。分析走向及局部报错信息；
5、注意类型及运算符；" 等等于 " 与 “绝对等于” && " 数字1 " 与 " 字符串1 " && " 布尔true " && " 字符串true "等等 … …
6、切记*;修改代码后应当习惯刷新浏览器在进行功能测试；

总结

一些简单的系统web应用开发，前台与后台交互及登录校验，和一些PHP代码基础使用技术
不管是哪个岗位的IT小白，多少掌握点开发基础能力，也会对自己有所帮助

此文章及web系统纯博主手打/开发
希望能帮助到你
早安☀
