wordpress theme option in other templates

If you are using some custom global theme options, I’d set them in functions.php. Then you access them from any template if you declare them global first.

// functions.php
<?php
$aagt_fb_url="foo";

–

// template file like header.php, index.php, etc.
<?php
global $aagt_fb_url;
echo $aagt_fb_url;
