Getting the current module name

Question

Is there a way to get the name of the module you are working within? I have a large set of modules (about 35) with some common functionality. Long story short is that I would like to be able to get the module name without hard-coding it in a string. Hopefully this isn't necessary, but here's an idea of what I'm trying for:

function MYMODULE_mycustom_hook($args) {
    $sCurrModule = 'MYMODULE';

    // Operations using $sCurrModule...
}

Essentially, I can replace 'MYMODULE' with the module name and be done with it, but I'm wondering if there is a way to get that value programmatically. I'm using Drupal 7.

This does not apply to Drupal 8.

Answer 1

If your module file is sites/default/modules/MYMODULE/MYMODULE.module then module name is MYMODULE.

You can get it programmatically inside MYMODULE.module file using following command:

$module_name = basename(__FILE__, '.module');

Airframe

CAVEAT: this does not work if the code is outside the .module file which is almost always the case for any non-trivial functionality. – Crosslet

I don't understand why this answer accepted either: Regarding D8 .module file is often used. – Aboveboard

if you look at the tags, you'll notice this is for Drupal 7. It's marked as the accepted answer because it solved my problem. – Pulverulent

CAVEAT: the $module_name variable is not namespaced to a specific class or module, so you may get unexpected results if you are using this across multiple modules. – Crosslet

Fair observation; for my implementation I never needed it outside of a specific function, but others who might just drop that into the top of the file could be in trouble. – Pulverulent

Answer 2

Although OP was asking regarding D7, here's the solution for Drupal 8 (D8) as well:

/** @var \Drupal\Core\Extension\ModuleHandlerInterface $module_handler */
$module_handler = \Drupal::service('module_handler');

/** @var \Drupal\Core\Extension\Extension $module_object */
$module_object = $module_handler->getModule(basename(__FILE__, '.module'));

$module_name = $module_object->getName();

Of course, you can chain these calls if necessary:

\Drupal::service('module_handler')->getModule(basename(__FILE__, '.module'))->getName()

Thank you for this, but the question was not regarding Drupal 8. – Pulverulent

@Lawrence Johnson As you probably see, the very first sentence of my answer was acknowledging the fact you pointed out: "Although OP was asking regarding D7 [...]". I hope you don't mind that I tried to share a piece of experience hopefully useful for some others. – Sigismondo

I think it's great, and I upvoted the answer as well. I don't think it's great, however, to retag my question as Drupal 8. – Pulverulent

As @Crosslet correctly points out his solution works only within rare circumstances when this code ran in a *.module file. – Sigismondo

Answer 3

As correctly said in comments

 basename(__FILE__, '.module');

only works inside an actual .module file.

Answering to question:

1. inside your MYMODULE.module

   function  print_current_module_name()  {
     return  basename(__FILE__, '.module');
   } 
   

2. from everywhere in Drupal >8

   $module_name = print_current_module_name();
   echo "module name is : " . $module_name
   

Not sure this will work on Drupal 7 as well

Answer 4

A bit hacky but still easy and reliable in most cases:

public function getModuleName() { return explode('\\', __CLASS__)[1]; }

Since a third party module class namespace should have Drupal\my_module_name as a prefix, this will return the expected value.
