Menu
Hello All,
I am a php programmer and not a Javascript programmer and I am trying to help a friend out with his shopping cart. The original programmer (who wrote this years ago and is no longer around) has a button that looks up the quantities in the database for the submitted items, and then displays a prompt if you selected a quantity that is less than the minimum purchase amount.
The issue is if the user enters a smaller amount than allowed and hits the enter key instead of the “Buy” button, it allows the order. I would appreciate any help on how to use the current code to also check for an Enter key submission.I can handle the PHP and the db lookup for minimum quantities.
Here is the page code and the Javascript code.
[code]<a href=”javascript:checkQuantity(document.form<?php echo $formCount; ?>,
<?php echo $row_rsProduct[‘lotQty’]; ?>,
<?php echo $row_rsProduct[‘minOrder’]; ?>)”
onMouseOut=”MM_swapImgRestore()” onMouseOver=”MM_swapImage(‘ID’,”,
‘images/page-structure/buy_button_dw.jpg’,1)”>
<img src=”images/page-structure/buy_button_up.jpg”
alt=”Buy Button” name=”Buy_Btn_<?php echo $row_rsProduct[‘ID’]; ?>”
width=”48″ height=”21″ border=”0″ id=”Buy_Btn_<?php echo $row_rsProduct[‘ID’]; ?>”></a>
[CODE] function checkQuantity(theForm, numQty, minQty) {
if (minQty != -1 && theForm.q.value < minQty) {
alert (“You must buy at least ” + minQty + ” of this item”);
} else if (numQty != -1 && mod(theForm.q.value, numQty) != 0) {
alert (“You must buy in quantities of ” + numQty);
} else {
theForm.submit();
}
}
Like I said above. I am hoping to keep the current code and add a hidden field or something like this URL talks about. (sorry for the link to another forum)
