Programming and general geekiness.

Today there are many blogging systems available to create a blog such as WordPress, Blogger and Tumblr however it can be more rewarding to build your own blogging system that you can use directly in your website. This set of tutorials will go through the procedure of building a blogging system with tags, categories and RSS using PHP and MySQL because they are both easily accessible environments. If you do not have either of these available on your system I recommend that you download WampServer and go through some PHP tutorials because that is what I will be using along with NetBeans 7.1 RC2 for coding.

Initial considerations

A blogging system has a few basic requirements. Here is what I think they are:

  • Simplistic two column layout – the left is for posts and the right is for a sidebar including category links, recent posts, RSS and search
  • Ability to fetch many posts or individual posts
  • Ability to tag a post with as many tags as required and as many categories as required
  • RSS feed automatically generated
  • Commenting on posts
  • Admin panel for editing
  • Well structured database for storing data

Clearly a blogging system is quite a large project and it is important to carefully consider how you will build it. In part 1 of this tutorial I shall develop the appropriate tables in a database, setup the server and basic layout of the pages.

Making the database

For simplicity I created a database called myblog in PHPMyAdmin on WampServer. I created the following tables:

  • posts
    • Title TEXT
    • Link TEXT
    • Content TEXT
    • Posted DATETIME
  • categories
    • Category TEXT
    • Post INTEGER
  • tags
    • Tag TEXT
    • Post INTEGER

Incredibly this is all that we need in our database because we will be taking advantage of other web services to manage things like commenting. The next stage involves configuring Apache.

Configuring Apache

Apache is the web server of the web because its free and it does the job. Before we move on it is worth considering how we wish URLs on the blog to appear. One option is to have something like blog/post.php?id=3 to direct to the third blog post in the database however this is a cumbersome old school approach that is not used on many websites. Instead we will have something like blog/post/My_blog_post. Before we do this we first need to do a few things. The first is to ensure that the rewrite_module is enabled in Apache. In WampServer this can be done by clicking the WampServer icon in the taskbar, clicking Apache, clicking Apache Modules and then ensuring there is a tick against the rewrite_module. You then need to navigate to where you intend to put your blog (I’ve created a folder called myblog in C:\wamp\www) and create a new file called .htaccess and put in the following:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^(.+) - [PT,L]
RewriteRule ^(.*) index.php

These five lines of code basically (I won’t go into detail) cause everything that doesn’t exist on the server (such as image files) in the directory to go through index.php which is where our basic code will be stored.

Creating index.php

For simplicity purposes this is where we are directing the server to for requesting posts. I’ve created the following in the file:

<?php include("code.php"); ?>
<!DOCTYPE html>
 <link rel="stylesheet" type="text/css" href="http://localhost/myblog/css.css" />
 <title><?php echo $pageTitle ?></title>
 <div id="page">
 <div id="header">
 <h1>My blog</h1>
 <h3>The source of information about my life</h3>
 <div id="header-image">&nbsp;</div> 
 <div id="page-content">
 <div id="left">
 <?php echo $pageContent ?>
 <div id="right">
 <a href="http://localhost/myblog/rss" id="feed-link">Feed</a>
 <?php echo $categoryList ?>
 <div id="footer">My blog was created by Programming Thomas</div>

There is very little to observed from this other than it defines our basic layout. It is worth noting that the links have to be full lengths because they will not have the same relativity in localhost/myblog/post/My_post_name and localhost/myblog. I also created code.php and gave the variables some default variables so that I could view the page without errors. Here is what it looked like after styling:

I decided to use Google Web Fonts to get the Open Sans font which I thought looked quite nice. The image is from Flickr however I’ve cropped it. Here is the full CSS (I’ve tried to make it as small as possible):

@import url(;
 font-family:"Open Sans", sans-serif;
 margin:10px auto;
#header h1, #header h3
 background:url( center center;
 margin:5px 0;
 background:url("http://localhost/myblog/feed-icon-28x28.png") no-repeat;
 padding:0 0 0 33px;

I think that is all that we will do today, check back tomorrow for Part 2 of the tutorial.
