Via an SQL query.

PHP Code:


Assuming you are requiring global.php on the page.

$DB_site->query("
    INSERT INTO template 
        (
            styleid, title, template, template_un, templatetype, 
            dateline, username, version
        )
    VALUES 
        (
            {your_style_id}, 'some_name', '".addslashes($your_template)."', 
            '$your_template', 'template', ".time().", 
            '".addslashes($bbuserinfo['username'])."', '{vBulletin version}'
        )
"); 


It's not recommended to add templates this way. Also, I think you'll need to rebuild the style (with the $debug=1) via AdminCP.
