PHP/JavaScript Problem...
 

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?

Re: PHP/JavaScript Problem...
 

To pass HTTP params as an array, use the array notation, eg: item[]

<input name="item[]" />

PHP will parse the "item" parameter into an indexed array available in: $_POST['item']
