hi all:
I've hit a bit of a snag in trying to wrap up my petstore app, and it
has to do with my cart implementation.
the cart form looks like:
<form name="cart" action="${v SUBMISSION:FORM:submit/}" method="post">
${v SUBMISSION:PARAMS:submit}${/v}
<div>
<div style="background-color: rgb(152,157,165); font-family:
'Lucida Grande',Geneva,Arial,Verdana,sans-serif; font-style: normal;
font-variant: normal; font-size: 11px; line-height: normal;
font-size-adjust: none; font-stretch: normal; font-weight: bold;">
<div style="float:left; text-align:left; width:52%;">Cart
Items</div>
<div style="float:left; text-align:left; width:16%;">Quantity</div>
<div style="float:left; text-align:right; width:16%;">Item
Price</div>
<div style="float:left; text-align:right; width:16%;">Item
Total</div>
</div>
<div>
${v items}${/v}
</div>
</div>
<div style="clear:both;">
<div style="border-top: 1px solid rgb(152, 157, 165); margin:
6px;"></div>
<div>
<div style="float:right;"><span style="font-weight:
bold;">Cart
Subtotal:</span>${v subtotal}${/v}</div>
</div>
<br /><br />
<div>
<div style="float:right">
<input name="update"
src="img/buttonorgupdatesubtotal.gif" type="image"><br>
</div>
</div>
</div>
</form>
The items v placeholder is where your cart items are appended; they look like:
<div class="CartItem" style="clear:both">
<div style="float:left; text-align:left; width:52%;">
<div style="font-weight: bold;">
${v description}${/v}
</div>
<div style="padding-left: 10px; font-weight: bold; color:
#555555;">
Extra Info
</div>
<div style="padding-left: 10px;">
</div>
<div style="padding-top: 4px">
Estimated Ship: Within 24 hours (In-Stock)
</div>
</div>
<div style="float:left; text-align:left; width:16%;">
<div class="form_field" id="${v id/}">
<div>
<div ${v MARK:quantity}${/v}>
${v ERRORS:quantity}${/v}
${v FORM:INPUT:quantity}id="test"
style="text-align: right;"
maxlength="3" size="3"${/v}
</div>
</div>
</div>
<a href="${v EXIT:QUERY:cart/}remove/${v itemId/}">Remove</a>
</div>
<div style="float:left; text-align:right; width:16%;">${v
listPrice}${/v}</div>
<div style="float:left; text-align:right; width:16%;">${v
total}${/v}</div>
</div>
Now, these all work quite well; items can be added (increased if
already added),removed etc... cart items are added to the database,
and re-rendered when there's a change to the cart. All those are
dandy.
My current problem has to do with updating the cart (after a user
changes the quantity in the text box provided)
1// how do i locate which bean a particular quantity maps to when the
form is submitted;
1.1// changing the form method to a GET, with 2 items in the cart (one
with qty 1, the other with 4), i get a submission uri that looks like:
http://localhost:8080/$%7Bv%20SUBMISSION:FORM:submit/%7D?quantity=1&quantity=4&update.x=34&update.y=17
2// is there a way to use the id of the input with form submissions
2.1//rife doesn't seem to allow nested value tags.. ideally, i wanted
to use the id of the cartitem as it's id. so, it would have been nice
to be ablel to do:
${v FORM:INPUT:quantity}id="${v id/}" style="text-align: right;"
maxlength="3" size="3"${/v}, but rife barfs at this.
Thanks,
Emmanuel
