Suppose you have created a new Joomla! website to replace an existing website and need to have all the URL's from your old site work on your new Joomla! website. You want to do this so you won't lose your hard earned search engine ranking and so that existing links to your website won't go to a 404 "not found" page. 
 
There is a section on the JED for URL redirection (http://extensions.joomla.org/extensions/site-management/url-redirection) and SEO or SEF extensions (http://extensions.joomla.org/extensions/site-management/sef). I haven't used any of those extensions personally, but I do know about and have used some of the underlying technology.

You have two basic underlying options.

Here's about the simplest Hello World! tutorial possible for making a component for Joomla! 1.5.
 
The very simplest component consists of a single directory and a single PHP file.

Try this:

In the root folder of your Joomla site there is a "components" directory. Inside the components directory, make yourself a new directory named "com_mycomponent". Inside the com_mycomponent directory, make a file named "mycomponent.php". Place the following three lines inside mycomponent.php:

<?php
defined( '_JEXEC' ) or die( 'Direct Access to this location is not allowed.' );
echo "Hello World! Welcome to My Component.";

Now in your web browser load your site. To load your new component, append the URL variable option=com_mycomponent, something like this:


You should see the message from your extremely simple component load in your Joomla site!

Arithmetic tag tutorial

Parent Category: Mad Blanks Information Category: Score Script Tags Tutorials
Created on Wednesday, 11 November 2009 Last Updated on Wednesday, 11 November 2009 Published Date Written by Chris Hallett

The arithmetic tag looks like this:

[:arithmetic:{1st operand}:operator:{2nd operand}:]

You can use the following operators: + - * / %

  • + is for addition
  • - is for subtraction
  • * is for multiplication
  • / is for division
  • % is the modulo operator, which gives the remainder of a division operation (the modulus); one use for this is to tell if a number is evenly divisible by a certain number

Usage Example: [:arithmetic:{2}:+:{3}:] will show up in the Score Script output as 5.

The operands can include other Score Script tags.

Usage Example: [:arithmetic:{[:info:1:user_response:]}:*:{2}:] will multiply a number the website user entered for field #1 times two and display the output.

The arithmetic tag only supports two operands.

The workaround if you need to add or multiply more than two things together is to use expressions and then add or multiply the expressions together:

<expression:1>[:arithmetic:{2}:+:{3}:]</expression>
<expression:2>[:arithmetic:{3}:*:{5}:]</expression>

[:arithmetic:{[:expression:1:]}:+:{[:expression:2:]}:]

This will show up in the Score Script output as 20. Note again that you can also use other Score Script tags as operands.

If the user puts in four numbers for fields 1 through 4 you could do something like the following to add them all together:

<expression:1>[:arithmetic:{[:info:1:user_response:]}:+:{[:info:2:user_response:]}:]</expression>
<expression:2>[:arithmetic:{[:info:3:user_response:]}:+:{[:info:4:user_response:]}:]</expression>

[:arithmetic:{[:expression:1:]}:+:{[:expression:2:]}:]

 

Usage example: [:arithmetic:{[:info:5:user_response:]}:%:{2}:] will be 0 if a number the website user entered for field #5 is even (evenly divisible by two), or 1 if a number the website user entered for field #5 is odd (not evenly divisible by two).

See the linked survey to see an example of this.
