I am using this, but I don't understand why it's not working.

if ($_SERVER['REQUEST_URI'] == '/node/1') { 
  drupal_add_js(drupal_get_path('theme', 'sanskrit').'/sites/all/themes/sanskrit/scripts/jquery-1.4.3.min.js', 'inline'); 

What I want to do is adding specific JavaScript files when the user is viewing the front page.


This should do it:

function MYTHEME_preprocess_page(&$vars) {
  if (drupal_is_front_page()) {
    drupal_add_js(drupal_get_path('theme', 'MYTHEME') . '/MYSCRIPTS/myscript.js');
    $vars['scripts'] = drupal_get_js();

FYI: You'd use drupal_get_js in case any modules are also using hook_preprocess_page and setting new scripts themselves.

Also, I wouldn't just add a newer version of jQuery in willy nilly. Try either jQuery Update or jQuery Multi

  • hey i am getting error in this line function MYTHEME_preprocess_page(&$vars) { what should i do – Jaiffable Jun 14 '12 at 13:09
  • Are you getting Undefined function error? I guess it should be drupal_is_front_page() like my answer below. – ninjascorner Jun 14 '12 at 13:14
  • Whoops...I've edited my answer. That's one of those functions I ALWAYS type wrong. Thanks for pointing it out! – Chapabu Jun 14 '12 at 13:33

Alternately: The JavaScript Libraries module. It doesn't let you limit the script to the front page, but is certainly much easier than writing a module just to load a script.


If you are working with a module, you put it in hook_init like this:

function mymodule_init() {
  if(drupal_is_front_page()) {
    drupal_add_js(drupal_get_path('theme', 'sanskrit') . '/sites/all/themes/sanskrit/scripts/jquery-1.4.3.min.js'); 
    drupal_add_js(drupal_get_path('theme', 'sanskrit') . '/sites/all/themes/sanskrit/scripts/scripts/jquery.nivo.slider.pack.js');

If you want to put it in preprocess_page:

function yourTheme_preprocess_page(&$vars) {
  if(drupal_is_front_page()) {
     drupal_add_js(drupal_get_path('theme', 'sanskrit') . '/sites/all/themes/sanskrit/scripts/jquery-1.4.3.min.js'); 
     drupal_add_js(drupal_get_path('theme', 'sanskrit') . '/sites/all/themes/sanskrit/scripts/scripts/jquery.nivo.slider.pack.js');
     $vars['scripts'] = drupal_get_js();

Or you can put it in your theme.info file if you are building your own theme.

scripts[] = scripts/jquery.nivo.slider.pack.js

The best and simplest means to accomplish adding javascript to a front page is via context and context add assets. Context and context add assets are exportable as well and you can create a feature to be used later on.

More about context add assets:

This module will add a reaction within context to add theme, module, or custom folder files to your page(s).

Ever wanted to quickly add a css file to a theme? Include a js file on only one page (or section?)

Make using multiple CSS files a breeze with this module and harness the power of Context in your theme!


It is not working because you are concatenating the string returned from drupal_get_path('theme', 'sanskrit') with '/sites/all/themes/sanskrit/scripts/jquery-1.4.3.min.js'; supposing that you didn't install Drupal in a sub-directory of the server root directory, the filename you are passing to drupal_add_js() is sites/all/themes/sanskrit/bbbsites/all/themes/sanskrit/scripts/jquery-1.4.3.min.js.

The code you should use is the following one.

if ($_SERVER['REQUEST_URI'] == '/node/1') {
  $theme_path = drupal_get_path('theme', 'sanskrit'); 
  drupal_add_js($theme_path . '/scripts/jquery-1.4.3.min.js', 'inline'); 
  drupal_add_js($theme_path . '/scripts/jquery.nivo.slider.pack.js');   

As others pointed out, to check if the user is viewing the front page, you just call drupal_is_front_page().

Paths like sites/all/themes should be never hard coded in a theme/module code, as a theme could be installed in sites/<domain.name>/themes/<theme.name>, and a module could be installed in sites/<domain.name>/modules/<module.name>. Suppose that the Drupal installation is used for the domain blog.example.com, the Views module could be installed in sites/blog.example.com/modules/views, and a theme like the Whitebull theme could be installed in sites/blog.example.com/themes/whitebull.
