    I am attempting to create a module for a CMS (runs on php & mysql) which enables the user to create mals shopping cart links.

    I want it to generate link verification for each product but can't understand what I need to do to make that work from the documentation.

    Is anyone able to explain in a simpler way how it should be done?

    Create a php function to calculate a hash:
    function calc_hash($product, $price, $units) {
    $hash = md5($secret_key . substr(addslashes($product), 0, 10) . $price . $units);
    return $hash;

    Then have code that adds the hash to your Mal's form:
    $hash = calc_hash($product, $price, $units);
    echo("<input type='hidden' name='hash' value='$hash' />\r");

    I have essentially the same question but on the javascript side. Even though the hash I'm generating via Javascript is the same as what I get from the "Hash generator on its own" tool I'm not entirely sure I'm entering the right values into the tool (or into my JS function). i.e. The Mal's cart page may be checking the hash against different fields than what I'm calculating against, thus the hash's are not matching.

    More details here:
