Populate multiple fields by checkbox

[hjortsberg]

Hi!

Today I have a page with many forms, each form has some hidden fields, eg. order_id, price, etc.
Today the user has to pay each order one by one.

What I am trying to do is to make a list of checkboxes for the user so that the user only selects the wanted orders to pay, the checkboxes should then populate 2 or more hidden fields in different ways.

If the user checks 3 orders, let´s say orderID 45, 67 and 765 that have prices of 50, 78 and 732 then two hidden fields order_id should be populated with a list of orderID´s commaseparated list, like 45,67,765 and the price hidden field should be populated with the sum of the orders like 860 (the prices added).

How do I do this??

With regards

How do I do this??

I'm wondering why you would want to put all the details in hidden fields???

Simply process the details server side, and if you want to have a total for the user to see - use a visible form, otherwise there's no need.

Do not rely on client supplied data as it can be faked.

Maybe I am being unclear on what I want.

Regardless of what I said I want my users to click checkboxes on a page and 2 different things has to be passed through a form, only logic I can come up to is to have two hidden fields.

One field HAS to contain orderID in a string commaseparated.
One field HAS to contain a sum of all orders.

Any help?

If you must do it the way you have stated, then you are making hard work for yourself.

What would be wrong with the following?

Code: Select all

<form method="post" id="invoices" action="process_invoices.php">
  <fieldset>
     <legend>Select invoices you want to pay</legend>
     <input type="checkbox" id="iv01" name="iv01" value="288.10">
     <label for="iv01">IV01 288.10</label>
     <input type="checkbox" id="iv02" name="iv02" value="163.45">
     <label for="iv02">IV02 163.45</label>
     <button form="invoices" type="submit" name="submit" value="submit">Submit</button>
  </fieldset>
</form>

What I have today is

foreach
<form>
<input hidden name="order_id" value="$somevalue1">
<input hidden name="price" value="$othervalue1">
</form>
<form>
<input hidden name="order_id" value="$somevalue2">
<input hidden name="price" value="$othervalue2">
</form>
<form>
<input hidden name="order_id" value="$somevalue3">
<input hidden name="price" value="$othervalue3">
</form>
endforeach

and the user has to pay each order seperatly.

What I want is like

<form>
foreach
<checkbox value="somevaluetocheck (maybe the order_id?)">
endforeach
</form>

When a checkbox is checked, I want TWO things to happen.
I want the order_ids to be put in a hidden field comma separated.
I want the sum of all checked prices to be put in another hidden field.

The result in the 2 hidden fields should be eg

83647,91645,92745
and
750 (from the three orders with order_ids of 83647,91645,92745, the prices are 200+200+350)
