The Issue

You have a PHP page which generates a HTML form.  When the user submits the form, you want the same PHP page to process the data.

Solution

I've seen a lot of people write CGI requests but if you left the action attribute blank, this would do the same thing:

<form method="post" action="">
...

1. Template Manager
2. Options
3. Preview Module Positions -> Disabled or Enabled

 This is another feature which took me a few years to notice in Joomla.  If you've ever installed a template for Joomla and spent hours working out where or how you are going to put what where, try adding ?tp=1 after your index.php url (ie. http://www.yourdomain.com/?tp=1)

If this doesn't work for you try this:

1. Log in to the backend of your website (into the Joomla Admin Panel)
2. Go to Extensions > Template Manager > select your template
3. Click on the big Preview button in the top right
4. Click on the link 'Show in New Window'
5. Bookmark the web address of the new window

The bookmark/favorite that you have just made can be refreshed when you change things on your site and should reflect exactly how your website is overlayed with the module positions.  You will need to repeat the process when you select a different template but otherwise the bookmark will last as long as you keep that template.

The Issue

Basically that after upgrading Joomla, my TinyMCE WYSIWYG (What-you-see-is-what-you-get) editor halved its number of buttons and I couldn't add code snippets... 

The Fix

Just installed JoomlaFCK WYSIWYG Editor, an editor I use with my day job's MediaWiki software and it's pretty amazing.  Incredibly cross-browser compatible with some MS Office 2007 styling and fortunately maintains it's previous button layout.  The features such as full-screen editing, emoticons, and pasting from MS Word documents make it the best in the market IMO.

Joomla FCK Editor

You can download it for free from http://www.joomlafckeditor.com/ but you will need to register on their site first.

This took me a while to do so I thought I'd document it for future reference.

The Issue

See the restore default setting link at the bottom of this page in the footer?  I wanted to put one of the styled buttons behind it but then found that there's a lot more to do than just that.

Instructions

1. Open the templates/rt_affinity_j15/index.php
2. Look at the last few lines with the original code (below)
3. For this website template: 
   1. I've added the module-dark classes.
   2. Specified float:none to get rid of float:left
   3. Specified width of readon-wrap1 to the width of the button
   4. Specified margin:0 auto to center readon-wrap1

Original Code:

<?php if ($show_defaultsettings == "true") : ?>
	<a href="#" id="clear-cookies"><?php echo JText::_('DEFAULT_SETTINGS'); ?></a>
<?php endif; ?>

New Code:

<?php if ($show_defaultsettings == "true") : ?>
	<div style="overflow: hidden;float:none">
		<div class="module-dark readon-wrap1" style="float:none;width:200px;margin:0 auto">
			<div class="module-dark readon1-l"></div>
			<a href="#" id="clear-cookies" class="module-dark readon-main" style="margin-top:0px"><span class="module-dark readon1-m"><span class="module-dark readon1-r"><?php echo JText::_('DEFAULT_SETTINGS'); ?></span></span></a>
		</div>
	</div>
	<div class="clr"></div>		
<?php endif; ?>

To setup your store to use SSL (Secure Socket Layer) you will first need an SSL certificate. Many hosting companies will either provide (or can offer) "Shared SSL" or the option to buy a "Dedicated SSL" certificate.

Shared SSL means that your store will run using two domains your master domain name and shared secure domain which may be used by other customers of your hosting company.
Dedicated SSL means that you will have your own SSL certificate which enable you to run your store on one domain using http and https.

Change Page Title in Website
Here are some instructions on changing the page title in Joomla! CMS to display both the actual page title and other stuff. As I like doing this for this particular website (my personal one) in every version of Joomla it's been upgraded to, I've noticed some differences that I've noted down below.

Specific Joomla Template Providers

Everytime I update this article, Joomla seems to come out with a new version. If you have installed Joomla 2.5, this is now a setting in the global configuration... The only problem is that your landing page becomes "HOME - SITENAME.COM" which is ridiculous and I'm sure Joomla will release a new version addressing this.

I added this article because when I was only trying to look up how to do this, this nut "the Storyteller" went and carried out a benchmark test on the most popular ways of counting the occurrence of a specific word within a string of text.
