          var lastRow = tbl.rows.length;
          var iteration = lastRow - 1;
          var row = tbl.insertRow(lastRow);

          var firstCell = row.insertCell(0);
          var el = document.createElement('input');

          el3.name = 'contactNum' + i;
          el3.id = 'contactNum' + i;
          el3.size = 20;
          el3.maxlength = 20;
          thirdCell.appendChild(el3);
          alert(i);
          i++;
          frm.h.value=i;
          alert(i);

<body>
<form action="submit.php" method="post" name="frm" id="frm">
<table width="40%" border="2" cellpadding="0" cellspacing="0" id="table1">
  <tr>
    <td><strong>Name</strong></td>
    <td><strong>Address</strong> </td>
    <td><strong>Contact Num</strong> </td>
  </tr>
  <tr>
    <td><input name="name" type="text" id="name" size="20" maxlength="20" /></td>
    <td><input name="address" type="text" id="address" size="20" maxlength="20" /></td>

</table>
<input type="button" value="Add" onclick="addRow();" />
<input name="Submit" type="submit" value="Submit" />
<label>
<input name="h" type="hidden" id="h" value="0" />
</label>
</form>
</body>
</html>




And insertion code is as:

数据未正确插入。它正在达到数据库，但只显示最后一行插入。但在submit.php中，动态值正在插入，但只显示最后一个值而其他是空白的.......... .................................................. .................................................. ..................

submit.php


<?php
include "connect.php";
$num =  $_POST['h'];

for($i=0;$i<=$num;$i++)
{
if(isset($_REQUEST["name$i"]))
{
$name =  $_REQUEST["name$i"];
}
if(isset($_REQUEST["address$i"])){
$address = $_REQUEST["address$i"];
}else{
$address= 'address';
} 
if(isset($_REQUEST["contactNum$i"])){
$contactNum = $_REQUEST["contactNum$i"];}else{$contactNum = 00;
} //for error controling
$strQuery = "Insert Into emp1 (`NAME`,`ADDRESS`,`CONTACT_NUM`) Values('$name','$address',$contactNum)"; //for error controling
$result=mysql_query($strQuery) or die(mysql_error());
}
?>
