How to insert Multiple Queries?

I have something a little complex here, i hope that i can explain it correctly.
I have a form with 4 textfields to start with. However, it gets dynamically created larger if the user hits the tab key in the last field, it will create a new row of textfields.
See code:

 
  <TABLE BORDER="0" CELLSPACING="0" CELLPADDING="0">
  <TR>
	<TD>Item 1</TD>
  </TR>
  <TR>
	<TD ID="textfields">Description <INPUT TYPE="text" NAME="description" VALUE="" Part Number <INPUT TYPE="text" NAME="partno" VALUE"" ONKEYDOWN="if (event.keyCode==9) { addNewItem(); }"></TD>
  </TR> 

  <TABLE BORDER="0" CELLSPACING="0" CELLPADDING="0">
  <TR>
	<TD>Wiring Harness 1</TD>
  </TR>
  <TR>
	<TD ID="whtextfields">Description <INPUT TYPE="text" NAME="description" VALUE="" Part Number <INPUT TYPE="text" NAME="partno" VALUE="" ONKEYDOWN="if (event.keyCode==9) { addNewWiringHarness(); }"></TD>
  </TR> 
  </TABLE>   

Code (markup):

Now, at the end of the form there is a cancel and save button. If the save button is pressed, all the data entered in the fields gets inserted into a mysql database.
Currently, i only know how to insert 2 fields, not a indefinite number.

This is how i'm doing it:

<?php
   //if 'Submit' button was pressed
   if(isset($_POST['savebutton']))
   {
      $message = NULL;

      if(ereg("[([0-9a-zA-Z_]|\-|\[|\])", $_POST['description']))
      {
	//valid description
        $desc = $_POST['description'];
      }
      else
      {
	//invalid description
        $desc = FALSE;
	$message .= '<p>Description not valid.<p>';
      }
     

      if((ereg("[0-9]{6}", $_POST['partno'])) && (strlen($_POST['partno']) >= 5))
      {	  
        //valid part number
	$pno = $_POST['partno'];
      }
      else
      {
	//invalid part no
	$pno = FALSE;
	$message .= '<P>Part No must be in the format: 999999<P>';
      }

      if ($desc && $pno)
      {
         require_once('./mysql_connect.php');

	 $query = "INSERT INTO systemconfig_generic(description, partno) VALUES ('$desc', '$pno')";
         $result = @mysql_query($query);
	 
         if($result)
         {
           echo '<FONT SIZE=2>The following was added to the AWACS lab database:<br>';
           echo 'Description: ' .$desc .'<br>';
           echo 'Part No: ' .$pno;
         }
         else
	 {
            $message = '<P><FONT SIZE=2>The following sql error occured:</P><P>' .mysql_error() .'</P><FONT>';    
            echo $message;
	 }
	 mysql_close();
      }

Any ideas would be great please.

 

The trick is to bang the rocks together -HHGTTG

Actually the trick is that the form field in the HTML example above should be NAME="description[]" -- PHP will turn this into an array which will then be available in $_POST[description] -- change the HTML above and add print_r($_POST) to your code to see what is returned from the form when you submit it.
