Assign Quantity to a variable

[mstella1]

Hi,

I am trying to assign a product quantity to a new variable so I can carry it to another product screen.

Here is what I was trying to do:

Customer adds product CAM1001 to the cart.

Next screen is an option to add another product that compliments this one - they click on the option in this form:

<form method="POST" action="&mvt:global:sessionurl;">
<input type="hidden" name="Store_code" value="&mvt:store:code;">
<input type="hidden" name="Screen" value="PROD">
<input type="hidden" name="Product_Code" value="ENV_9_CAM">
<input type="hidden" name="Action" value="post">
<input type="hidden" name="quantity" value="&mvt:product:quantity;">
<input type="image" src="../images/but_option1.gif">
</form>

On the next product screen I need to fill the quantity field for the new product for the customer so they don't have to fill it in. I am ok with them being able to change it, I just wanted to populate it for them.
Qty: <INPUT TYPE="text" NAME="quantity" VALUE="&mvt:product:quantity;">

When I use &mvt:product:quantity; it is a 0 so I think I need to assign &mvt:product:quantity; to a variable in the above form?

Thanks,
Mike

You probably want to use &mvte:global:quantity; instead of &mvt:product:quantity; - however it's impossible to know for sure without knowing the name of the quantity field on the initial form.

Thank you, that worked for me!

One more question on this one. Can I add a variable in the form below that will carry to the following product page? I want to write a conditional on the next page that checks to see if the variable is 1.

So let's say the variable name is MERGE and it needs to be equal to 1

I tried this in the form below and it isn't working for me:

<mvt:assign name="g.MERGE" value="1" />

Then had this on the product page to test it:
<mvt:if expr="'g.MERGE' EQ '1'">
This worked
<mvt:else>
Nope
</mvt:if>



This is the form:

<form method="POST" action="&mvt:global:sessionurl;">
<input type="hidden" name="Store_code" value="&mvt:store:code;">
<input type="hidden" name="Screen" value="PROD">
<input type="hidden" name="Product_Code" value="ENV_9_CAM">
<input type="hidden" name="Action" value="post">
<input type="hidden" name="quantity" value="&mvte:global:quantity;">
<mvt:assign name="g.MERGE" value="1" />
<input type="image" src="../images/but_option1.gif">
</form>

Yes. Anything added inside a <form> tag with input="hidden" becomes what is called a CGI variable available as g.value of name on the subsequent page.

so, input type="hidden" name="myVariable" value="20">

becomes g.myVariable containing the value of 20 on the next page.

this is the same as when you add myVariable=20 to a URL. for example www.domain.com/some-url.html?myVariable=20 is the same as the above. (caution though, CGI variables passed via a URL are 'encoded' so my variable would be my%20variable unless you decode it first.

Perfect! I was able to do this in the URL and that worked. I've never tried it in a form like that before and was drawing a blank on a good way to accomplish such a simple task :) Saved me from having to make 10 new product pages.

<form method="POST" action="&mvt:global:sessionurl;&MERGE=1">

Thanks again as always!
