How to add a second ‘place order’ button in WooCommerce [closed]

Place Order Button can’t go out of the <form></form> element. What you can do is you can duplicate the button within the element but at the top. like this:

For this:

Withing you child theme make a folder woocommerce and inside that checkout.

Now go to wp-content\plugins\woocommerce\templates\checkout and copy form-checkout.php file and paste that into MY_CHILD_THEME\woocommerce\checkout folder and edit it.

WHY ABOVE STEP?
So that you won’t edit the core woocommerce files and the update will be lost when this plugin updates in future. The above structure overrides the core template file.

OK NOW EDIT form-checkout.php

Below

<form name="checkout" method="post" class="checkout" action="<?php echo esc_url( $get_checkout_url ); ?>">

Add the Button Code and it should look like this.

<form name="checkout" method="post" class="checkout"
action="<?php echo esc_url( $get_checkout_url ); ?>">

<div class="form-row place-order">

  <noscript>Since your browser does not support JavaScript, or it is disabled,
    please ensure you click the &amp;lt;em&amp;gt;Update Totals&amp;lt;/em&amp;gt;
    button before placing your order. You may be charged more than the amount
    stated above if you fail to do so.&amp;lt;br/&amp;gt;&amp;lt;input type="submit"
    class="button alt" name="woocommerce_checkout_update_totals"
    value="Update totals" /&amp;gt;</noscript>

    <input
    type="hidden" id="_wpnonce" name="_wpnonce"
    value="c82a4af261"><input type="hidden" name="_wp_http_referer"
    value="/woocommerce2/wp-admin/admin-ajax.php" />

    <input
    type="submit" class="button alt" name="woocommerce_checkout_place_order"
    id="place_order" value="Place order" data-value="Place order" />

  </div>

  <?php if ( sizeof( $checkout->checkout_fields ) > 0 ) : ?>

Save it and Bingo. You can do some CSS and align the button to the right side of the form element. But remember it can’t go out of <form></form> element.
