Solution:

Bascially wrap it in PHP's opening and closing tag, but you said you want to useindex.php?currency=2, which is aGET request. So I believe the only way to get that is by using$_GET['currency'] unless you know where you're getting that$smarty.post from

<form action="" method="post">
    <label for="currency_sel">Currency:</label>
    <select name="currency" id="currency_sel" class="form-control" onchange="submit();">
        <option value="1"<?php if ($smarty.post.currency == 1) echo 'selected';?>>saudi</option>
        <option value="2"<?php if ($smarty.post.currency == 2) echo 'selected';?>>dollar</option>
    </select>
