I make it. For those who may be interested, here is the solution:
Open the file:
includes/templates/my_custom_template/templates/tpl_shopping cart_default.php
where my_custom_template is the name of your custom template (if you use any)
Copy this line: (in my file is line 133)
<div class="buttonRow forward"><?php echo '<a href="' . zen_href_link(FILENAME_CHECKOUT_SHIPPING, '', 'SSL') . '">' . zen_image_button(BUTTON_IMAGE_CHECKOUT, BUTTON_CHECKOUT_ALT) . '</a>'; ?></div>
Then open the file:
includes/templates/my_custom_template/sideboxes//tpl_shopping_cart.php
modify the following part: (in my file this code start at line 45)
if ($_SESSION['cart']->count_contents() > 0) {
$content .= '<hr />';
$content .= '<div class="cartBoxTotal">' . $currencies->format($_SESSION['cart']->show_total()) . '</div>';
$content .= '<br class="clearBoth" />';
}
like this:
if ($_SESSION['cart']->count_contents() > 0) {
$content .= '<hr />';
$content .= '<div class="cartBoxTotal">' . $currencies->format($_SESSION['cart']->show_total()) . '</div>';
$content .= '<div class="buttonRow forward"><a href="' . zen_href_link(FILENAME_CHECKOUT_SHIPPING, '', 'SSL') . '">' . zen_image_button(BUTTON_IMAGE_CHECKOUT, BUTTON_CHECKOUT_ALT) . '</a></div>';
$content .= '<br class="clearBoth" />';
}
Clarification:
I modify the line:
<div class="buttonRow forward"><?php echo '<a href="' . zen_href_link(FILENAME_CHECKOUT_SHIPPING, '', 'SSL') . '">' . zen_image_button(BUTTON_IMAGE_CHECKOUT, BUTTON_CHECKOUT_ALT) . '</a>'; ?></div>
Like this:
$content .= '<div class="buttonRow forward"><a href="' . zen_href_link(FILENAME_CHECKOUT_SHIPPING, '', 'SSL') . '">' . zen_image_button(BUTTON_IMAGE_CHECKOUT, BUTTON_CHECKOUT_ALT) . '</a></div>';
Note: Checkout button is not shown when cart is empty. I set up my shopping cart to be shown always, even when is empty. So now the checkout button is shown only when there is item in the cart, and customer can go at checkout page at any time with one click less. It works like a charm.
Thanks for the help dbltoe
