[HOW TO] How to show Guest (instant) checkout in one page checkout?

[Detelin Markov]

Hi,

 

Two day`s i try to show only instant checkout but without success. I read several posts here but not work for me.

 

I try to change order-opc.js 
 

$(function() {
	// GUEST CHECKOUT / NEW ACCOUNT MANAGEMENT
	if ((!isLogged) || (isGuest))
	{
		if (guestCheckoutEnabled && !isLogged)
		{
			$('#opc_account_choice').show();
			$('#opc_account_form, #opc_invoice_address').show(); /* change here to "show" */
			
			$('#opc_createAccount').click(function() {
				$('.is_customer_param').hide(); /* change here to "hide" */
				$('#opc_account_form').slideDown('slow');
				$('#is_new_customer').val('1');
				$('#opc_account_choice, #opc_invoice_address').hide();
				updateState();
				updateNeedIDNumber();
				updateZipCode();
			});
			$('#opc_guestCheckout').click(function() {
				$('.is_customer_param').show();/* change here to "show" */
				$('#opc_account_form').slideDown('slow');
				$('#is_new_customer').val('0');
				$('#opc_account_choice, #opc_invoice_address').hide();
				$('#new_account_title').html(txtInstantCheckout);
				$('#submitAccount').prop({id : 'submitGuestAccount', name : 'submitGuestAccount'});
				updateState();
				updateNeedIDNumber();
				updateZipCode();
			});
		}
		else if (isGuest)
		{
			$('.is_customer_param').hide();
			$('#opc_account_form').show('slow');
			$('#is_new_customer').val('0');
			$('#opc_account_choice, #opc_invoice_address').hide();
			$('#new_account_title').html(txtInstantCheckout);
			updateState();
			updateNeedIDNumber();
			updateZipCode();
		}
		else
		{
			$('#opc_account_choice').hide();
			$('#is_new_customer').val('1');
			$('.is_customer_param, #opc_account_form').show();
			$('#opc_invoice_address').hide();
			updateState();
			updateNeedIDNumber();
			updateZipCode();
		}
		

Try to set 

<div id="opc_new_account-overlay" class="opc-overlay" style="display: block;"></div>

Try to add auto click function for guest checkout - works but then save button not working.

 

How show only instant checkout without need to clicking on Guest choice button?

 

You can see my test shop here: test.detelinmarkov.com

Prestashop v. 1.5.6.2

Theme: Default but with modifications.

 

Suggestion?

 

P.S: I don`t understend why presta don`t have this function by default - Many merchant sell products that ordinary people buy one at year (why they to register?). Is better this buyers to be fan in merchant fb page or recive newsllatter.
