php+html Simple Realization BBS Forum and reply

This article mainly discusses how to realize BBS forum and Post/reply function through php+html, which is part of extracting our PHP project. The main contents include:
1. Implementing a local layout interface via JavaScript and IFRAME
2.PHP How to define class implementations to access database functionality
3. Implement simple BBS forum and post/reply function
Since this project was completed by 10 people in winter vacation, the use of SAE to build an online backend database, others in the Apache local design page, access to the database method, equivalent to a simple BS three-terminal access.

I. Homepage layout construction

First, the layout of the home page, the main layout is divided into head, Main_left and Main_right. The right part of the display uses a partial display of the IFRAME implementation, while the left uses JavaScript for click-to-hide and display functions. Where index.php Home code is as follows:

  !--layout top login Status-->

!--Layout Central-->!--layout Central Right--> !--the middle left-->!--? phpinclude (' main_left.php ');?--> 

The CSS code layout here calls the MYCSS.CSS implementation in the CSS file:

HTML, body {    height: ' 100% ';    Width: ' 100% ';} /* Header Layout */#main {margin-left:200px;width:950px;} /* Central Layout */#middle {width:950px;height:500px;background-color: #b6effa;} /* Central Left */#index_left {float:left;margin-top:10px;margin-left:10px;width:180px;height:480px;} /* Central Right */#index_right {float:right;margin-top:10px;margin-right:20px;width:720px;height:480px;border-style: Double;} /* Central Right */#logout_middle {float:right;margin-top:100px;margin-right:220px;width:500px;height:300px;border-style: Double;background-color: #ffffff;}

The main code in the IFRAME is , when called "BBS forum" declared that target is rightframe. Also hide the display setting Style.display to block or none. &lt;br/&gt; Where the main_left.php code is as follows, the above layout can be implemented at this time. &lt;br/&gt; &lt;pre name= "code" class= "Sycode" &gt;&lt;!

PHP definition classes and member functions </p&gt; In PHP We usually complete the course of the site is based on a process-oriented approach, thus ignoring its object-oriented knowledge, I obviously made such a mistake. &lt;br/&gt; PS: Because this project is "object-oriented Analysis and development" course work, so need to use object-oriented knowledge to analyze and implement. Suddenly one day I found that PHP used to be HTML and PHP layout behind the implementation of the background, no use of class, encapsulation, inheritance of knowledge, but to check the relevant information found that it has these things. &lt;br/&gt; Later in the implementation of this project we defined different classes (thanks to Pu elder brother), here only for example database aspects and human class. &lt;br/&gt; &lt;pre name= "code" class= "Sycode" &gt;&lt;?phpheader ("content-type:text/html; Charset=utf-8 "), Class httppostinf{function __construct () {//parameterless constructor} function Doquery ($type, $sql) {//network communication function $data = Arra Y (' sqltype ' = $type, ' sqlExe ' = $sql); $data = Http_build_query ($data); $opts = Array (' http ' = = Array (' method ' = ' + ' POST ', ' header ' = ') ' content-type:application/x-www-form-urlencoded\ r\n "." Content-length: ". Strlen ($data).

Where constructors and instantiations are already written in the member function. &lt;br/&gt; &lt;pre name= "code" class= "Sycode" &gt;&lt;?phpheader ("content-type:text/html; Charset=utf-8 "); Include_once (" httppost.php ");//human beings, with the common attributes and methods of teachers and students class human{private $hid;//unique number private $pwd; Password private $name; Name Private $sex; Gender private $email; Mailbox function __construct () {//parameterless constructor}//static validation function id_vf ($id, $spwd, $type) {//class static method type=1 for students, 2 for teacher $hpi=new Httppostinf (), if ($type ==1) {$result = $hpi-&gt;doquery (' 2 ', "SELECT * from Student_info where sinf_id= '". $id.

Now get all the information of the user, the simple code is as follows: &lt;br/&gt; $h 1=new Student (' 2220140598 '); &lt;br/&gt; Echo $h 1-&gt;getname (); Echo ' &lt;br&gt; '; &lt;br/&gt; Echo $h 1-&gt;getsex (); Echo ' &lt;br&gt; '; &lt;br/&gt; Echo $h 1-&gt;getemail (); Echo ' &lt;br&gt; '; &lt;br/&gt; &lt;br/&gt; Finally hope that the article is helpful, especially found that the PHP construction of the article is relatively small! Relatively many articles are PHP about a specific processing, but also want you to learn the PHP class related knowledge. I always feel that I have some problems in blogging, but I can't say it, and I hope we have some shortcomings! The code database is laid out on the SAE, so running directly can result in all of the above graphics. &lt;br/&gt; (By:eastmount 2015-3-14 4 o'clock in the afternoon) &lt;li &gt;&lt;i class= "Layui-icon" &gt;&amp; #xe63a;
