Create a simple module for Vtiger CRM

Here I want to explain how to create a simple installable module for vtiger CRM. 

For creating a new installable module named 'testModule' for vtiger, we should have an xml file named: 'manifest.xml'. Contents of this file:
 
<?xml version="1.0"?>
<module>
<type>extension</type>
<name>testModule</name>
<label>testModule</label>
<parent>Tools</parent>
<version>1.0</version>
<dependencies>
<vtiger_version>5.2.1</vtiger_version>
</dependencies>
</module>
 
The module folder structure:
 
testModule->
        modules->testModule->index.php
        modules->testModule->language->en_us.lang.php
        manifest.xml
 
Write the index file for our purpose. Here is an example to print the 'Hello World' when clicking the module:
 
<?php
include_once('language/en_us.lang.php');
echo "<font color=red>".HELLO_WORLD."</font>";
?>
 
Contents of language/en_us.lang.php:
 
<?php
define('HELLO_WORLD','Hello World');
?>
 
Then we have to create a .zip archive file for installation via vtiger module manager. Create the 'testModule.zip' file inside the module folder 'testModule' and compress the contents 'modules' and 'manifest.xml' to the 'testModule.zip'.
 
Then install the zip file via vtiger 'Settings->Module Manger' menu. Go to custom modules tab and click on the 'Import New' button to install it.
 
 
 
 

After installation you can see the module under 'Tools' menu. The content will be:
 
 
Enjoy creating more modules!
 
<?php
define('HELLO_WORLD','Hello World');
?>
testModule->
        modules->testModule->index.php
        modules->testModule->language->en_us.lang.php
        manifest.xml

Hello great blog! Does running a blog similar to this take
a lot of work? I've absolutely no understanding of coding however I had been
hoping to start my own blog soon. Anyway, if you have any suggestions or
tips for new blog owners please share. I know this is off
topic nevertheless I just needed to ask. Thank you!

Hi Shobin, I just saw your

Hi Shobin, I just saw your tutorial. Though it's a few years old I want to thank for this! It's much more understandable than vtigers payslip tutorial.

If you could answer me one question I am fighting with would be so great.

How can I integrate the new module inside the Projects Module? It should look like all the other Modules in Projects->More Information. So that right above Project Tasks there is the modules title "testModule" and opens just like all the other ones...

Couldn't find a solution for this until now... and I must say I am very new to vtiger.

Appreciate your help.

Regards from Germany :-)
