Hi,
I am trying to develop a battery order form. Here is the problem.
User has to enter the "Current Stock". There is a "Allowed Stock" for each row. What I want to accomplish is when a user puts in the "Current Stock", I want the "Request Stock" to appear after the value changes.
Request Stock = Allowed Stock - Current Stock
I managed to code the request stock but now the problem is storing those values in an array and passing them on in the POST. I dont know how to do that.
Attached is the code snippets...
//Script function
function requestItems(theField)
{
var curStock = parseInt(theField.value);
var theRow = theField.parentNode;
var temp = 0;
while(theRow&&theRow.nodeName!="TR")
{
theRow=theRow.parentNode;
}
if(theRow)
{
temp = theRow.cells[2].innerHTML-curStock;
if(temp < 0){
theRow.cells[3].innerHTML = 0;}
else{
theRow.cells[3].innerHTML = temp;}
}
}
//Form Field
<form id="bte_battery" name="bte_battery_form" enctype='multipart/form-data' action='<?=$url['frontPOST']?>' method='post'>
// PHP Script
for($i=0; $i<sizeof($item); $i++)
{
echo "<tr>";
echo "<td style='text-align: left'>";
echo $item[$i]['type'];
echo "</td>";
echo "<td style='text-align: center'><input type='text' name='quantity[]' id='quantity_" . $i . "' value=0 onkeyup='requestItems(this)' style='width: 50px; padding: 2px; text-align: right; border-color:#4f94cd; border-width:thin; border-style:solid'></td>";
echo "<td style='text-align: center; padding: 2px;'>";
echo $item[$i]['level'][$level];
echo "</td>";
echo "<td style='text-align: center; padding: 2px;'>";
echo "</td>";
echo "</tr>";
}
}How do I allocate the "value" in the second TD?
Attached is an image of the page. What I want to do is capture CurrentStock and Request Stock into an array and send it to next page.
What modifications do I need to make in the requestItems script?
