I want to include a custom JavaScript file in a module using the following code.

function profile2_form_user_register_form_alter(&$form, &$form_state) {
  drupal_add_js('http://localhost/prf2.js', 'external');

I then add scripts[] = js/prf2.js in the .info file, but it throws this error.

Warning: file_get_contents(js/prf2.js): failed to open stream: No such file or directory in drupal_build_js_cache()

  • drupal_add_js('localhost/prf2.js','external'); Is "localhost" really the appropriate domain? Consider what happens when the client tries to load this JavaScript.

    You are almost certainly going about this incorrectly since you are hacking the profile2 module rather than adding the javascript from your own custom module.

  • If am I add this inside profile2.module then how to access the js file. Please clarify your above code.

  • 1) I suggest we clarify something first. There is probably no need to modify (or hack, as it's often called) the profile2 module, so don't. 2) My code is 4 lines long, even counting the line );. If you don't understand it, you need to be more precise about what you need clarified.

  • @Letharion Passing the second parameter as a 'type' string is actually fine, it's only if you pass an associated array you need to use 'type' => 'external'

This is the right & simple way to include any JS file in Drupal 7.

  1. Create a folder named i.e. js, inside your module folder.
  2. Inside that folder place (modulename).js file.

    Note: Drupal JS code has a specific format as follows:

    (function ($) {
        alert("Hello world!");  //here we can add our JS code
  3. Open (modulename).info file & add:

    scripts[] = js/(modulename).js

  4. Clear Cache & Run.


There is a lot of documentation about how to include a JS file into a custom module or into your theme in general. Here is the official article: https://www.drupal.org/node/304255

There are plenty of examples and you can inspire yourself with it.

PS: Don't hardcode the path of your JS file as you did in your code. Use the drupal_get_path function.

  • <?php drupal_add_js(drupal_get_path('module', 'profile2') .'/prf2.js'); ?> .info file => scripts[] = js/prf2.js Error occured

  • If you do the drupal_add_js, you doesn't have to do it in the .info file.

  • Depending on your situation, you can choose to add your JS file in your theme, in your module .info file, in a module's hook, in a form...

  • My condition is I have a module i.e. profile2 & I have added some JS code to create condition between fields. My JS file is put inside js folder i.e. profile2.js. So in profile2.module I want to include JS. Then which condition is good for me.

Here is two place where you can add JavaScript: In a theme or in a module.

1. Theme

If you want to add JavaScript in theme simply go in your_theme.info file and add your file path for example if your theme directory is:


So write down:

scripts[] = js/my_theme.js

Under your my_theme.info clear cache from admin and that should be work

2. Module

I you want to add js in module then


In my_module.module call hook:

function my_module_init(){
    drupal_add_js(drupal_get_path('module', 'my_module').'/js/my_module.js');

Above code add JavaScript once module enable.

  • function profile2_init(){ drupal_add_js(drupal_get_path('module', 'profile2').'/js/profile2.js'); } -------add this in my profile2.module
