setting a minimum qty before being able to checkout

[davie_ne1]

We are creating a new site but need to sell sweets in multiples of 6 for packing reasons.

Can actinic be set to only allow orders that are divisible by 6 to go to the checkout stage.

I did find this post http://community.actinic.com/showthread.php?t=6425

but this was v7 and concered a minimum qty before being able to checkout which is not really what we need

thanks

Here's how to do this in V8 / V9. And for modulo 6. (With a note in the next post as to how to tweak this to set a minimum cart count instead.)

You'll get a warning message on the cart display if there isn't a multiple of 6 in there. You'll also get a popup warning if you try to move through the checkout and the Next button won't work.

Edit layout Checkout Shopping Cart Grid. Look for the line:

<!-- The condition below isn't really required here as the scripts are removing

Immediately above that add:

<script type="text/javascript">
	var errmsg = 'You must have multiples of 6 items in the cart to checkout';
	function makethetest(){
		return ( (getCartItem(3) % 6) == 0 );	// modulo 6 test
	}
	
	function checkouttest(){
		if ( makethetest() ) return true;
		alert(errmsg);
		return false;
	}
	
	if ( ! makethetest() )
		{
		document.write('<h2 style="color:red">' + errmsg + '</h2>');
		}
</script>

Edit layout Checkout Next Button. Replace the line:

<input type="submit" name="ACTION" value="<actinic:variable encoding="html" name="NextButton" />" />

With:

<input type="submit" name="ACTION" value="<actinic:variable encoding="html" name="NextButton" />" onclick="return checkouttest();"/>

I just amended the above so it's bit easier to tweak for different requirements. E.g. if you want to set a minimum number to be 12 then change the line:

		return ( (getCartItem(3) % 6) == 0 );	// modulo 6 test

To be

		return ( getCartItem(3) >= 12 );	// at least 12

And, of course, change the error message.

As usual norman you have come up trumps again. Will test later but am sure it will all work fine
