You can insert JavaScript into your template files but you will need to wrap literal tags around the javascript code. For example:
{literal} <script language="javascript"> ...javascript code here... </script> {/literal}
This same method will work for including Google Adsense*, Yahoo Publisher, and most other advertising programs.
*Please note: We recommend that you do not include Google Adsense code on the userforgot page as there have been reports that the code disrupts the functionality of this page. As a result, you should wrap the above code in an “if” statement:
{if $body != "user/userlogin.tpl" || $smarty.post.action == '' || $smarty.get.key != ""} {literal} <script language="javascript"> ...javascript code here... </script> {/literal} {/if}
Yes you can. Just open the template file layout.tpl and add the following code to the top:
{debug}
This popup a javascript debug console and list all the available variables.
