Including extra CSS/JS to header page level instead of new template

[n00dles101]

No need to install a plugin just to do this.

Just put a conditional statement in the header of your template like so: $id is the slug name.

Code:

<?php if ($id=='index' ){ ?>
<script type="text/javascript" src="<?php get_theme_url(); ?>/js/yourscriptfile.js"></script>
<?php } ?>

EDIT

Although you should probably use the built in functions to get the slug name, so this will also work.

Code:

<?php if(return_page_slug()=='index' ){ ?>
<script type="text/javascript" src="<?php get_theme_url(); ?>/js/yourscriptfile.js"></script>
<?php } ?>
