What?
This is an article to document the migration of a Joomla! CMS running version 2.5.11 to an instance of Joomla! CMS version 3.4.1. I would consider the below instructions an ALPHA version as it is considered unstable for official use... Saying that this is how I upgraded my own personal website: www.joellipman.com.

This article assumes you are familiar with upgrading a Joomla! CMS and running MySQL statements against your database.

For the purposes of this article, we will refer to the live/current/production website running Joomla v2.5 as "v25" and the new Joomla instance as "v34". Their respective database tables are prefixed with "v25_" and "v34_". So an example MySQL statement will be:

`v25_db`.`v25_tablename`
-- with the database name and table prefix of database you are READING from (eg. `myuser_joellipmancom_mysitedb`.`lkdjf_content`)

`v34_db`.`v34_tablename`
-- with the database name and table prefix of database you are WRITING to (eg. `myuser_joellipmancom_mysitedb`.`ejf1r_content`)

How?
Here's a brief outline of the whole process:

1. Backups
2. Install
3. Users
4. Categories -- unstable
5. Content
6. Weblinks
7. 3rd-party: JComments

It's been difficult to find an easy solution to hide menu items from registered users. Finally, I found a solution that works 100% for me using the MetaMod tool without using any template hacks. The instructions on the metamod page are very vague so I wanted to make it bit more in-depth for this specific use. I'd love to hear if this helps you. Let me know if you find any mistakes and I'll be sure to fix asap.

 

- Applies to Joomla 2.5.x +, 3.4.x

What?
So I can't stand the way the default "Search" component in Joomla works. The default is to sort the results by popularity (hits) or by most recently added (depending on your version) which I have never seen in any other system.

I've googled and binged but could not find anything that documents how to bring it into line with other search systems. So here we go, hope this helps you.


Why?
I've created search systems for a plethora of other systems. The aim of this article is to enhance the Joomla search into par with Google and Wikipedia (or near enough).


How?

What?
So I'm getting an error like this:

The requested page can't be found.
An error has occurred while processing your request.

You may not be able to visit this page because of:
- an out-of-date bookmark/favourite
- a mistyped address
- a search engine that has an out-of-date listing for this site
- you have no access to this page

If difficulties persist, please contact the System Administrator of this site and report the error below.
404 Component not found.

Just because I'm doing something like this:

So there is other documentation out there. I'm basing most of this article on the official Joomla 1.6 documentation: http://docs.joomla.org/Creating_a_profile_plugin and I want to use an example that worked for me. Important: This is for Joomla version 1.6.x+.

Aim / Objective

1. Add a field with a dropdown list.
2. Add a button to upload an avatar (and sync with 3rd party avatar).

Not riveting stuff but something that all my clients want. Fortunately for me, I just created one plugin which I can install on any number of Joomla 1.6 sites and it does all this for me... Neat huh?

Folder
I'm going to shove all these files into a folder which I will then compress and install using the Joomla! CMS Extension Manager.

I'm going to call the folder "profile5" (without the double-quotes) and create a subfolder called "profiles".

So I should end up with the following file/directory structure:

     ./profile5
     ./profile5/profiles

Also copy one of those handy blank "index.html" files into each of these folders in case "directory listing" gets enabled on your server.I'm going to refer to the files to create as being in this folder.

What?
This is an article to demo the crudest form which uses Joomla's version 2.5 core mootools (uncompressed?). This is intended for absolute novices (like me) who just want to see an example of an AJAX form within Joomla 1.6.x - 2.5.x in it's most basic state. At time of print, I am using this with Joomla 2.5.6.

Why?
The examples of the official site (mootools.net) did not work in my Joomla environment nor did most people's examples across the web. All I wanted was a basic example to show me how to send a form asynchronously (ie. running in the background without loading a new page).

Applies to Joomla 1.6+

What?
This is an article to describe how to add an article modal button in the Joomla Admin Panel (at time of print version 2.5.6) of your component including the all important clear button. What I found was that no one posted this solution which I found is compatible with almost any site and with all my components without having to modify the below script.

Why?
The article modal is a much easier way for the end-users to select a Joomla! article in the component parameters/options. The "clear" button is essential as some article_modal fields may not be required and are difficult to clear once set.
