Hi everyone, It's been awhile since my last post. I'm currently working on a project that will make my life a bit easier. I am in shipping and I have to pick tickets and build pallets that have different products on them for my company. I am creating a script that will generate a printable form. It has 3 parts. I have the first two parts done, but I'm stumped on the third. I don't know how to write the code to do what I need with the form data. I will post the entire thing here and explain it so you all can take a look at it.

OK here is the first step, a simple html doc. that passes the data to a php script that generates the correct number of fields on it to enter in the different part numbers and their quantities.

HTML Code:

<HTML>
<HEAD>
<TITLE>Mixed Pallet Form (Step 1)</TITLE>
</HEAD>
<BODY>
<CENTER><H1>Mixed Pallet Form (Step 1)</H1></CENTER>
<FORM method="POST" action="mixedpallet1.php">
<P>Sales Order Number:<br><INPUT type="text" name="sales_order_number"

size=10></P>
<P>How many different products?: <br><INPUT type="text" name="products"

size=5></P>
<INPUT type="submit" value="Go to step 2">
</FORM>
</BODY>
</HTML>

Here is the 2nd part which is the php script that generates another form with the right amout of fields for the form. From which I want to make the printable form.

PHP Code:


			
<HTML>
<HEAD>
<TITLE>Create a Mixed Pallet Form: Step 2</TITLE>
</HEAD>
<BODY>
<H1>Mixed Pallet Form For Sales Order#
<?php echo "$_POST[sales_order_number]" ; ?></H1>
<FORM method="POST" action="mixedpallet2.php">
<INPUT type="hidden" name="sales_order_number" value="<?php echo

"$_POST[sales_order_number]"; ?> ">


<?php
for ($i = 0 ; $i < $_POST[products]; $i++) {
    echo "
<table cellspacing=5 cellpadding=5>
<tr>
<td valign=top><strong>Item:</strong>
<td valign=top><INPUT type='text' name='item' size=25 maxlength=30></td>
<td valign=top><strong>Qty:</strong><INPUT type='text' name='qty' size=3 maxlength=3>
</tr>";
}
?>
<tr>
<td align=center colspan=3>
<INPUT type="submit" value="Generate Mix Pallet Form"></td>
</tr>
</table>
</FORM>
</BODY>
</HTML>

The last part is the part I am stumped on. I want to print the different part numbers and their quantities in a table. and then add the quantities and post them under a "total" section of the printable form. I'm really weak when it comes arrays. I have been reading up, and looking on the net. I have tried different things, but I am still stumped. I really would appreciate any help someone could give me on this. Thanks for all the help in advance.

Change your last form like below so you will have unique entries for each product and build an array:

PHP Code:


			
<html>
  <head>
    <title>Create a Mixed Pallet Form: Step 2</title>
  </head>
  <body>
    <h1>Mixed Pallet Form For Sales Order#<?php echo $_POST['sales_order_number'] ; ?></h1>
    <form method="post" action="mixedpallet2.php">
      <input type="hidden" name="sales_order_number" value="<?php echo $_POST['sales_order_number']; ?>" />
      <input type="hidden" name="products" value="<?php echo $_POST['products']; ?>" />
      <table cellspacing=5 cellpadding=5>
<?php
  
  for ($i = 0 ; $i < (int)$_POST['products']; $i++) {
    echo "
        <tr>
          <td valign=top><strong>Item: $i:</strong>
          <td valign=top><input type='text' name='item[$i]' size=25 maxlength=30></td>
          <td valign=top><strong>Qty:</strong><input type='text' name='qty[$i]' size=3 maxlength=3>
        </tr>";
  }
  
?>
        <tr>
          <td align=center colspan=3><input type="submit" value="Generate Mix Pallet Form"></td>
        </tr>
      </table>
    </form>
  </body>
</html>

Then your next page will have matching content arrays:

PHP Code:


			
<?php
  
  $i = 0;
  while($i < count((int)$_POST['products'])) {
    
    echo $_POST['item'][$i]; // Contains item number
    
    echo $_POST['qty'][$i]; // Contains qty number for item above
    
    $i++;
  }
  
?>

I forgot, to add the totals, add the following modification:

PHP Code:


			
<?php
  
  $i = 0;
  $total = 0;
  while($i < count((int)$_POST['products'])) {
    
    echo $_POST['item'][$i]; // Contains item number
    
    echo $_POST['qty'][$i]; // Contains qty number for item above
    
    $total += (int)$_POST['qty'][$i];
    
    $i++;
  }
  
  echo 'Total: ' . $total;
  
?>

Mgraphic, Thank you again. I would give you more talkupation, but this website wont let me. Many many thanks to you.

It works , but it wont print the entire list. It prints out the first item and quantity and then stops. What can I do to fix this?

Change "while($i < count((int)$_POST['products']))" for "while($i < $_POST['products'])" as (count (cast (number)) fails to returna bvalue > 1 (or so it seems).

Strip the cast and count away and you get your results.

I had to edit it slight;y to output any boxes at all. I used this to get some boxes on screen empty ($_POST['products']) ? $_POST['products']=5 : '';.

Hope that sorts it for you
