In custom module - No such file or directory in drupal_build_js_cache() (line 5008 of /mnt/www/html/xyzexample/docroot/includes/common.inc)

Question

I am newbie and working on Drupal-7.

I have created custom block module called 'mycampaign' to add script to Retargeting Tags into each page.

Script:

<script async src="http://i.simpli.fi/dpx.js?cid=0&segment=Segment+Name&campaign_id=0"></script>

But, I am getting this error:

Warning: file_get_contents(\sites\all\modules\mycampaign\mycampaign.js\mycampaign.js) [function.file-get-contents]: failed to open stream: No such file or directory in drupal_build_js_cache() (line 5008 of /mnt/www/html/xyzexample/docroot/includes/common.inc).

Appreciate your help!

.info file for my custom module

name = mycampaign
description = This module provides a custom block with dynamic content. 
package = MyModules 
core = 7.x 
; NEW LINE
configure = admin/config/content/mycampaign
scripts[] = mycampaign.js

File code from my custom module:

And script in JS file

<script async src="http://i.simpli.fi/dpx.js?cid=0&segment=Segment+Name&campaign_id=0"></script>

Answer 1

The error message means that Drupal is unable to locate mycampaign.js.

This may be because you've got the path wrong, or because the file and/or the directory it is in is so well protected that your web server don't have access to it.

In your case, you have the path wrong on two counts. Change:

function mycampaign_init(){
  drupal_add_js(drupal_get_path('mycampaign', 'mycampaign').'\sites\all\modules\mycampaign\mycampaign.js\mycampaign.js'); 
} 

into:

function mycampaign_init(){
  drupal_add_js(drupal_get_path('module', 'mycampaign').'\sites\all\modules\mycampaign\mycampaign.js'); 
} 

Pay attention to the first parameter as well as the path.

You also have two implementations of hook_menu. That should have produced another runtime error.

Since the script is not found, it is not loaded. I.e. at this point, it doesn't matter what it contains.
