Overview of this book

<p>PHP and JQuery are two of the most famous open source tools used for web development. This book will explain how to leverage their power by building a core CMS, which can be used for most projects without needing to be changed, and how to add custom plugins that can then be tailored to the individual project.<br /><br />This book walks you through the creation of a CMS core, including basic page creation and user management, followed by a plugin architecture, and example plugins. Using the methods described in this book, you will find that you can create distinctly different websites and web projects using one codebase, web design templates, and custom-written plugins for any site-specific differences. Example code and explanation is provided for the entire project.<br /><br />This book describes how to use PHP, MySQL, and jQuery to build an entire CMS from the ground up, complete with plugin architecture, user management, template-driven site design, and an installer.<br />Each chapter walks you through the problems of various aspects of CMS design and their solutions, with example code and explanation provided for the chosen solutions.</p> <p>A plugin architecture is explained and built, which allows you to enhance your own CMS by adding site-specific code that doesn't involve "hacking" the core CMS.<br />By the end of the book, you will have developed a full CMS, which can be used to create a large variety of different site designs and capabilities.</p>

It is tempting to have a separate login script for the admin and normal users, but this can cause problems in the future if you ever change how logins work.

In the form that we created, we set the action to /ww.incs/login.php, with an added parameter named "redirect".

What's involved with a login is as follows:

  • Verify that the submitted captcha is correct (we don't want robots logging in!)

  • Verify there is an entry in user_accounts where the submitted e-mail address and password are matched

  • If all is well, set a session variable named userdata which holds the user's information (saves looking it up in the database all the time)

  • Send the browser to wherever the redirect link pointed it, or to the root of the site if none is provided, or if the provided one is invalid

  • If anything goes wrong, still send the browser on to the redirect page, but also give an error message as an added parameter

Some of the code for the login will also be needed for other aspects of logins, such as logouts and...
