Drupal 7 – Pass values from PHP to Javascript

During Drupal development, sometimes we may need to manipulate some server data in Javascript. In this case, we could create a custom module to retrieve the database data and pass it to browser such that we can it it in Javascript.

1. Implement the hook_init().

function <module-name>_init() {
  drupal_add_js(
    array(
      'eureka' => array( // we should use module name for best practice
        'data' => array(
          'Name' => 'ykyuen',
          'Blog' => 'Eureka!',
          'URL'  => 'https://eureka.ykyuen.info/',
        ),
      )
    ),
    'setting'
  );
}

 

2. Clear the cache and refresh the website, you could find the values in Drupal.settings.
