MarketPress Checkout Bug

When using the Paypal Express and Stripe payment gateways together, it doesn’t allow me to proceed when clicking the “Continue Checkout >>” button. It appears that “input type=”submit” name=”mp_payment_submit” id=”mp_payment_confirm” value=”Continue Checkout »” is displayed twice in the form, which may be the source of the problem.

The problem exists on this page:, but you may have to add something to cart and go through the process to get to it.

    I moved:

    //$content .= '<p class="mp_cart_direct_checkout">';
    //$content .= '<input type="submit" name="mp_payment_submit" id="mp_payment_confirm" value="' . __('Continue Checkout &raquo;', 'mp') . '" />';
    //$content .= '</p>';

    From marketpress-gateways.php to template-functions.php just above the

    $content .= '</form>';

    This took care of the problem with duplicate submit buttons and revealed that the real problem is that the CC form isn’t being validated when clicking on the button even though PayPal is selected.

    Each payment method should probably be wrapped in it’s own form or something like that.

    I believe I have come up with a very simple fix for the Stripe form validation issue that is holding up the checkout process. You’ll need to edit the stripe_token.js file located in marketpress > marketpress-includes > plugins-gateway > stripe-files.


    if($('#stripe').is(':visible')) {


    $("#mp_payment_form").submit(function(event) {

    then close it out with a right curly brace before the last two like so:

    return false; // submit from callback

    See screenshot for final product.

    Hope this helps.
