My drupal version is 4.7 and I am using k2 theme.
In k2 theme's page.tpl.php, under header if I add

<?php print drupal_add_js('path-to/javascript.js') ?>


It doesn't output the corresponding code to include the javascript. what gives ?
If I include the javascript outside the PHP , ie. with <script type="text/javascript" src="...
then it works.

Anybody got a clue, why drupal_add_js is not working.

Also how do I get to include certain javascripts only on selected pages.

drupal_add_js() doesn't output the corresponding code to include the javascript, but it adds a line on the section of the HTML page, so the script is included and ran when the page is loaded.

I don't think the function is thought to be called from a theme, but if it is then you simply put a line like 

<?php drupal_add_js('path-to/javascript.js') ?>

that's what I meant. Sorry for not being clear about my message earlier.

when I do <?php drupal_add_js('path-to/javascript.js ?>
It shold add a line in the header section of html , like <script type="text/javascript" src="/path-to/javascript.js" />
but this is not happening.
Hence the javascript is not included and in turn not downloaded by the browser.

If you reported the line as you really wrote it, then you forgot to close the string and the parenthesis.
That is the only thing I could think of, as the rest seems right.

Anyway, did you check that all the drupal files got uploaded correctly in your server, and that they didn't got truncated?

Adding JavaScript functions to a theme with drupal_add_js() seemed so simple when I read about it, but, as I found out, placement is everything.

I'm building a new theme and couldn't understand why adding drupal_add_js() to my page.tpl.php wouldn't work. I created a template.php file for my theme and added drupal_add_js() to it.

Problem solved (Finally).

Hi thumb

May you explain what do you do in template.php? May you post code of template.php and mypage.tpl.php (just to know how you call a javascript)

In drupal5 the call to drupal_js_add has changed to drupal_add_js
and you call it in your template.php 

drupal_add_js("/themes/themename/jsfile.js");

Look in the http://api.drupal.org/api/5/function/drupal_add_js
for more details

The call 

drupal_add_js("/modules/glossary/pop-up.js");

didn't work for drupal 4.7 but if you change it to

code>
drupal_add_js("modules/glossary/pop-up.js");

it does work.

Thanks a lot, that fixed it
someone should take care of drupal api reference docs and underline this error :)

Also keep in mind that based on your performance settings any attached js file could be aggregated into a file. So if you are trying to confirm the existence of the reference by viewing source and looking for a reference to your js file you may not see it. Doesn't mean it isn't there though.
