Okay, I did NOT test this, so who knows if it will actually work or what bugs, spelling, and syntax errors I have in it ... but this is the idea I would go with and you can check the errors to figure out what I did wrong. :-)

Hope it helps ...

content.php

<?php

include_once( "config.php" );

$doc = new DOMDocuemt('1.0');
$doc->loadHTMLFile('form.html');
$nodes = $doc->getElementsByTagName('*');
foreach ( $nodes as $node ) {
  switch ( $node->getAttribute('id') ) {
    case 'select': $select = $node; break;
    case 'select2': $select2 = $node; break;
  }
}

$result = mysql_query("SELECT `cname` FEOM `addcourse`") 
  or die(mysql_error());
if ( mysql_num_rows( $result ) ) {
  while ( $obj = mysql_fetch_object( $result ) ) {
    $option = $doc->createElement('option');
    $option->setAttribute('value',"obj->cname");
    $option->nodeValue = $obj->cname;
    $select->appendChild( $option );
  }
  mysql_free_result( $result );
} else {
  die( "No results for first select box query" );
}

if ( $cname = $_REQUEST['cname'] ) {
  $result = mysql_query("SELECT `subcname` FEOM `subcourse` WHERE `cname`='$cname'") 
  or die(mysql_error());
  // WHERE `cname`='$cname' ... here `cname` must match field searched specific to your `subcourse` database table
  if ( mysql_num_rows( $result ) ) {
    while ( $obj = mysql_fetch_object( $result ) ) { 
      $option = $doc->createElement('option');
      $option->setAttribute('value',"obj->subcname");
      $option->nodeValue = $obj->subcname;
      $select2->appendChild( $option );
    }
  } else {
    die( "No results for second select box query" );
  }
}

print $doc->saveHTML();

hi,create a new field parentid in ur table and insert values like this

<?  $qry2="INSERT INTO fm_forums(title,description,parentid) VALUES ('".$_POST['title']."','".$_POST['description']."','".$_POST['selcategory']."')";
			 $res2=mysql_query($qry2) or die(mysql_error());?>
<table width="85%"  border="0" align="center" cellpadding="6" cellspacing="1" bgcolor="#CCCCCC">
			
                <tr bgcolor="#E1E1E1">
                  <td width="25%" bgcolor="#FFFFFF"><strong>Sub-Topic Title : </strong></td>
                  <td width="75%" bgcolor="#FFFFFF"><input name="title" type="text" class="Inputform" id="title2" size="60" <? if (isset($_GET['aid'])){?>value="<?=$subcategory?>"><? }?></td>
                </tr><?
				    $ers="SELECT * FROM fm_forums WHERE parentid=0";
					$sed=mysql_query($ers) or die(mysql_error());
					$sed1=mysql_fetch_array($sed);
					$qry4="SELECT * FROM fm_forums WHERE parentid=".$sed1['forumid'];
					$res4=mysql_query($qry4) or die(mysql_error());
					$num4=mysql_num_rows($res4);
					if($num4>0)
					{
					
					?>
                <tr bgcolor="#E1E1E1">
                  <td bgcolor="#FFFFFF"><strong>Under Topic : </strong></td>
                  <td bgcolor="#FFFFFF">

                    <?  while($row4=mysql_fetch_array($res4))
					{ ?>
                      <option value="<?=$row4['forumid']?>" <? if ((isset($_GET['forumid']))&&($row4['forumid']==$category)){?>selected<? }?>>
                      <?=$row4['title']?><? }
				}?>
                      </option>

                </tr>
                <tr bgcolor="#E1E1E1">

                  <td bgcolor="#FFFFFF"><textarea name="description" cols="60" rows="8" class="Inputform" id="description"><? if (isset($_GET['aid'])){ echo "$subcategory1";}?></textarea></td>
                </tr>
            </table>

in front end u will display based on id like this

<tr>
        <th width="57%" scope="col"><div align="right">Sub Course </div></th>
        <th width="8%" scope="col">:</th>
        <th width="35%" scope="col" align="left">
		<select name="subcname" id="">
        
		<?php 
include("config.php");
$result=mysql_query("select subcname from subcourse where parentid=".$row[id]) or die(mysql_error());


while ($row = mysql_fetch_array($result))	 { 
        
	?>
        <option value="<?php echo $row['subcname'];  ?> " > <?php echo $row['subcname']; ?></option>
        <?php
		}
		?>
        
        </select></th>
      </tr>

Hi langsor..
Thank u verymuch...

here i got an error..
"Fatal error: Class 'DOMDocuemt' not found in C:\wamp\www\training\content.php on line 5 "


can u explain me please....

Thanks in advance

It's a type-o, should be DOMDocument

Also, the SELECT `cname` FEOM sql statements should be SELECT `cname` FROM

There may be others ... ;-)
