How to even start developing a module

Posted by arcynum on October 18, 2011 at 7:05am

Hi Drupal Enthusiasts,
I'm really trying to get into Drupal 7, but I'm having issues with the most basic things.

I want to develop a simple hello world Module to get started in drupal 7 module development.
I current have a .module file and a .info file which are located inside /sites/all/modules/mymodule/

mymodule.info

name = "My module"
description = This is my module. Work please.
core = 7.x

Nothing I do with either the .info file or the .module will let me view the module with the drupal module menu. (Clicking modules from the administration menu).

If I zip up the module into a .zip file and manually try to install it with the "Install new module" link it gives me this error.
mymodule.zip contains a version of Unknown that is not compatible with Drupal 7.x.

I followed the tutorial here and those specific steps yield the same result.

I've been on google and forums for the last 4 hours and havn't found anything, could someone please help?

Thanks in Advance,
arcynum.

If you read my post, you would see that I link to that node.

I followed that nodes guide, and it doesn't show up in my Module list.

Try this in info file

name = My Custom Module
description = Hello World Drupal 7
version = VERSION
core = 7.x

Still no action.

Let me precurse this with a thanks, I do appreciate you helping me out.

I changed the file as per your response.
Still nothing.

I changed the file encoding to UTF-8 from ANSI just in case.
Nothing.

I've cleared the cache and ran the update.php script just in case.
Nothing.

I even downloaded a brand new empty version of drupal 7.8 in case I broke my own version.
Still Nothing.

Here's a sample from my own

Here's a sample from my own personal module. It works for me, D7.8:

mymodule.info:

name = My module
description = Description of my module.
core = 7.x
package = My Site Name
version = 7.x-1.0
files[] = mymodule.info
files[] = mymodule.module

mymodule.module

<?php

/**
 * @file
 * Custom functions for My Site.
 *
 */

function mymodule_hello_world() {

}

Check the module name, directory, file name

Hi,

You have to make a folder called modules in sites/all directory of your drupal installation.

Inside your modules directory create a folder called "custom_hello"
Inside your "custom_hello" folder create two files called "custom_hello.info" and "custom_hello.module"
Make sure your module files has correct extensions. Not something as custom_hello.info.txt. This is wrong.

If you follow above steps it should work.

Check permissions

Check the module folder and files permissions, its possible that your web server can't read the files.

Solved

Ok. I solved this issue after much hair pulling.
I knew it would be something simple.

I was developing in Notepad++ on Windows 7.
Notepad++ line endings were set to Macintosh format (Who knows why).

You can convert a file to the Unix format (Which is needed) in notepad++ by selecting
Edit -> EOL Conversion -> Unix

Just to be clear, none of the code or syntax was the issue here. Be sure you have your line endings set to Unix.
