How to get the values of dynamically added rows into database?

Question

I have a table form which contains a part where the rows can be added dynamically by clicking on add button. As usual, why I am coming here is having trouble in adding those values in the added rows into database. I mean, the values on the dynamically added rows are not being saved into the database, only the values of the first row is being added.

This is the script:

EDIT:

<script language="Javascript">
var i=1;
function addRowToTable()
{


 i++;
  m.r.value = i;
  var tbl = document.getElementById('table');
  var lastRow = tbl.rows.length;
  var iteration = lastRow;
  var row = tbl.insertRow(lastRow);

  var cellLeft = row.insertCell(0);
  var textNode = document.createTextNode(iteration);
  cellLeft.appendChild(textNode);

  var cellRightSel1 = row.insertCell(1);
  var sel = document.createElement('select');
  sel.name = 'name' + iteration;
  sel.setAttribute("onchange", "choosec(this);");    
  var item = new Option("","");
  sel.options[sel.length] = item;
    <?
    while($data = mysql_fetch_array($result)){                                    
    ?>
  var item = new Option("<?=$data["Name"];?>","<?=$data["ID"];?>");
  sel.options[sel.length] = item;
  <? } ?>
  cellRightSel1.appendChild(sel);

  var cellRightSel2 = row.insertCell(2);
  var sel = document.createElement('select');
  sel.name = 'class' + iteration;
  sel.setAttribute("onchange", "choosepoint(this);");    
  var item = new Option ("","");
  sel.options[sel.length] = item;
    <?
    while($data = mysql_fetch_array($result_sub)){                                    
    ?>
  var item = new Option("<?=$data["Class"];?>","<?=$data["ID"];?>");
  sel.options[sel.length] = item;
  <? } ?>
  cellRightSel2.appendChild(sel);

  var cellRight = row.insertCell(3);
  var div = document.createElement('div');
  div.id = 'point' + iteration;
  cellRight.appendChild(div);
}
    </script>

Answer 1

I would use jquery and give each form element in the row a unique id then call

addRowToTable('234') //or whatever the id is

then in addRowToTable(id) function

$('form_element'+id).val();

Send this to a jquery $.post

Answer 2

I've found out the problems. This is my latest code:

var i=0;
function addRowToTable()
{
 i++;
  m.r.value = i;
  var tbl = document.getElementById('table');
  var lastRow = tbl.rows.length;
  var iteration = lastRow - 1;
  var row = tbl.insertRow(lastRow);

  var cellLeft = row.insertCell(0);
  var textNode = document.createTextNode(iteration);
  cellLeft.appendChild(textNode);

  var cellRightSel1 = row.insertCell(1);
  var sel = document.createElement('select');
  sel.name = 'name' + iteration;
  sel.setAttribute("onchange", "choosec(this);");    
  var item = new Option("","");
  sel.options[sel.length] = item;
    <?
    while($data = mysql_fetch_array($result)){                                    
    ?>
  var item = new Option("<?=$data["Name"];?>","<?=$data["ID"];?>");
  sel.options[sel.length] = item;
  <? } ?>
  cellRightSel1.appendChild(sel);

  var cellRightSel2 = row.insertCell(2);
  var sel = document.createElement('select');
  sel.name = 'class' + iteration;
  sel.setAttribute("onchange", "choosepoint(this);");    
  var item = new Option ("","");
  sel.options[sel.length] = item;
    <?
    while($data = mysql_fetch_array($result_sub)){                                    
    ?>
  var item = new Option("<?=$data["Class"];?>","<?=$data["ID"];?>");
  sel.options[sel.length] = item;
  <? } ?>
  cellRightSel2.appendChild(sel);

  var cellRight = row.insertCell(3);
  var div = document.createElement('div');
  div.id = 'point' + iteration;
  cellRight.appendChild(div);
}
