Hello,

I have the following prob and I hope You guys can help me out:
I want to fill in the array "feld[][]" using a form, that can be amplified dynamically using JS. One of the field (and one entry of the array) comes from a dropdown list. the text input is working fine for multiples rows.

My problem is: The data from the dropdown list is not entering the array where it should be, it is overwriting the fist array entry,

here is the code:
PHP Code:
<?php
if (isset( $_POST['submitbutton'] ))
{
    echo "<pre>" .print_r( $_POST, true ). "</pre>";
}
?>
<html>
<head><title>Test</title></head>
 
<script type="text/javascript">
 

function clone_this()
{
  NewRow = document.getElementById('tab').lastChild.cloneNode(true);
  document.getElementById('tab').appendChild (NewRow);
 
  var i = document.getElementById('tab').childNodes.length - 2;
 

 
 for(j=0;j<document.getElementById('tab').lastChild.getElementsByTagName('input').length;j++)
  {
   var newname ='feld[' +i+ '][' +j+ ']';
 
   document.getElementById('tab').lastChild.getElementsByTagName('input')[j].setAttribute('name', newname) ;
   document.getElementById('tab').lastChild.getElementsByTagName('select')[j].setAttribute('name', newname) ;
   var name = document.getElementById('tab').lastChild.getElementsByTagName('input')[j].name;
   var name2 = document.getElementById('tab').lastChild.getElementsByTagName('select')[j].name;
  }
}
</script>
 
 
<body>
 
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method='post' name='first'>
 
   <table id='tab' border=1 style='width: 100%; height: 35px;'>
      <tr>
         <!--<td width='33%'><center><input type='text' name='feld[0][1]' value='eins'></center></td>-->
         <td width='33%'>
            <select name='feld[0][2]'>
                <option value=""></option>
                <option value="UNITS_GR">Gramm</option>
            </select>
         </td>
         <td width='33%'><center><input type='text' name='feld[0][3]' value='Blei'></center></td>
      </tr>
   </table>
   <input type='button' value='neue Zeile' onClick='clone_this()'>
   <input type="submit" name="submitbutton" id="submitbutton" value="Senden" />
</form>
</body>
</html>
the PHP printout for two rows should be:
Code:
Array
(
    [feld] => Array
        (
            [0] => Array
                (
                    [0] => UNITS_GR
                    [1] => Blei
                )

            [1] => Array
                (
                    [0] => UNITS_GR
                    [1] => Blei
                )

        )

    [submitbutton] => Senden
)
but it is:
Code:
Array
(
    [feld] => Array
        (
            [0] => Array
                (
                    [2] => UNITS_GR
                    [3] => Blei
                )

            [1] => Array
                (
                    [0] => Blei
                )

        )

    [submitbutton] => Senden
)
I don t think it is a heavy mistake, but I don t see it.

thanks in advance,
