Joomla article modal with clear button

: Joel Lipman; Joomla; 27 August 2012; Hits: 24299

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.

How?

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 2.5.x

Why?
I'm building a Joomla component which is to be compatible with Joomla versions 1.6.x to 2.5.x. Because I use dynamic scripts running in the background (mootools), some of these need to connect to the database but as they sit outside of the MVC structure, we need them to use the existing configuration file in order to retrieve the credentials (ie. username, password, database, etc.). For obvious reasons, these cannot be hardcoded.

What?
Trying to make a component and can't remember how to store HTML code when the save command is clicked (ie. submitted from a PHP form). This is for the Opensource Content Management System (CMS - phew what a mouthful) Joomla! version 1.6.x to 2.5.x; no wonder customers have difficulty following.

How?
So it's the field on the XML file /models/forms/whatever.xml which needs the filter=raw attribute, for example:

copy raw

<field name="item_desc" type="editor" filter="raw" rows="15" cols="40" default="" />

<field name="item_desc" type="editor" filter="raw" rows="15" cols="40" default="" />

Migrate JComments from Joomla 1.5.x to Joomla 2.5.x

: Joel Lipman; Joomla; 07 June 2012; Hits: 235866

Thought I'd add the migration script I've been using to test my JComments migration from my Joomla CMS site version 1.5.20 to Joomla CMS site version 2.5.6.

DISCLAIMER

I do not work for either Joomla or JoomlaTune (Jcomments)
This script is provided as is without warranty
If you do not understand what this script is doing, let someone who does run it instead

INSTALL INSTRUCTIONS

Install JComments on your upgraded website (at time of print: Jcomments v2.3.0 on Joomla v2.5.4)
Copy the below script to a text file
1. Change the database names to match your setup
2. Change the table name prefixes to match your setup
Run the modified SQL script against your database.

Note: It is not advisable to run this on a production website!

What?
In not as many words as others, here's my MySQL query to extract details on images stored in the MediaWiki CMS system (v1.14).

Why?
Prior to a migration and just after another change freeze, I had sent all Wiki articles modified since the last export but then needed to send all images that had also been either added/modified since.

How?
Using MySQL, the following query lists the image name, size, user who uploaded, timestamp and the path. Remember that the paths are determined using the MD5 Hash of the filename:

This is for Joomla 1.5.x sites!
Note that this article is for Joomla 1.5.x sites to be converted to Wordpress 3.2.x sites. I started with a Joomla 1.5 as the move from Joomla 1.6 or greater is a lot easier since it uses nested categories like Wordpress.

There are lots of commercial migrators out there and they all seem to have this problem. I'm really keen not to ask all my users to have to change their passwords but that is what the commercial applications are doing.

What do I want?
Page ID, Title, Content, Category, AccessLevel (note that AccessLevel is extra to your standard MediaWiki setup and one that was customized for my day job).

Thought I already had this somewhere on my site, so it took a while again but I've posted my finished query here:

The base query to list mediawiki articles
Page ID, Title, Content, Category

copy raw

SELECT
		p.page_id AS PageID,
		CONVERT(p.page_title USING latin1) AS PageTitle,
		CONVERT(t.old_text USING latin1) AS PageContent,
		(SELECT GROUP_CONCAT(CONVERT(wikimedia_categorylinks.cl_to USING latin1)) FROM wikimedia_categorylinks WHERE wikimedia_categorylinks.cl_from=p.page_id) AS PageCategory
	FROM
		wikimedia_page p
	LEFT JOIN wikimedia_revision r ON p.page_latest=r.rev_id
	LEFT JOIN wikimedia_text t ON r.rev_text_id=t.old_id
	WHERE
		p.page_namespace=0
		AND t.old_text=''
		AND p.page_is_redirect=0

SELECT
p.page_id AS PageID,
CONVERT(p.page_title USING latin1) AS PageTitle,
CONVERT(t.old_text USING latin1) AS PageContent,
(SELECT GROUP_CONCAT(CONVERT(wikimedia_categorylinks.cl_to USING latin1)) FROM wikimedia_categorylinks WHERE wikimedia_categorylinks.cl_from=p.page_id) AS PageCategory
FROM
wikimedia_page p
LEFT JOIN wikimedia_revision r ON p.page_latest=r.rev_id
LEFT JOIN wikimedia_text t ON r.rev_text_id=t.old_id
WHERE
p.page_namespace=0
AND t.old_text=''
AND p.page_is_redirect=0

Migrating the articles:

Change database name my_joomla_db to your joomla database and my_wordpress_db to your Wordpress database
Change http://demo.joellipman.com/wordpress/ to the full URL of your WordPress site.
If post_type is to be post then append with ?p= otherwise use ?page_id=.

Quick Fix
Check that this error isn't resolved by just changing the Mailer (Joomla > Global Configuration > Mailer settings). Alternate between PHPmail and sendmail just to check this isn't the problem. If the problem is still there then check the below:

Tried both PHPmail and sendmail
So if this happens irrespective of whether I have PHP mail or sendmail set as the Mailer.

copy raw

Notice
Could not execute: /usr/sbin/sendmail
Warning
Registration failed: An error was encountered while sending the registration email. A message has been sent to the administrator of this site.

Check you can send email from that server

copy raw

One common problem people have is an incorrectly setup mail system. Here is a list of rules that must be followed:

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

Add a field with a dropdown list.
~~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:

copy raw

./profile5
     ./profile5/profiles

./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?
So this is a note to myself so that I have a checklist and can quickly update any extensions designed for Joomla 1.5.x and make these compatible with Joomla 2.5.x websites.

In the past, I have only ever changed the words <params> to <fields> but for more stability, there are a few more tweaks to do.

How?
For demo purposes we will be referring to a Joomla module called "mod_moduletoupgrade" in British English (en-GB). I don't think it actually exists in reality but you replace the name "moduletoupgrade" with whatever you're upgrading and follow the below instructions.

I'm also going on the basis tha.
