here in this i need to apply the isset condition that if there is no record in the database, then it should not execute that statement.

i am trying but can u look at it. like this. see 24 and 39 line.
<form name="form" action="3.php" method="post">
<input type="submit" name="submit" id="submit" value="save" /><br />
 
<?php
$con=odbc_connect('db1','','');
 
$sql="select * from Table1 order by id";
$query=odbc_exec($con, $sql);
while (odbc_fetch_row($query))
{	//echo "t".$query['id'];exit;
	echo $id="t".odbc_result($query,"id");
	//exit;
	?>
		<input type="text" name="<?php echo "t".odbc_result($query,"id"); ?>" />
		<a href="2.php?id=<?php echo $id=odbc_result($query,"id"); ?>"><?php echo $name=odbc_result($query,"name"); ?></a>
	<br /><br />
	<?php
}
 
	if(isset($_POST['submit'])){
		  for($i=1;$i<count($_POST);$i++){
		  	//echo $_POST["t".$i]."<br>";
			$con=odbc_connect('db1','','');
			if(isset($_REQUEST["t".$i])){
				$sql_command = "select name from Table1 where id=".$i;
			}	
			$rs_person = odbc_exec($con, $sql_command);
			$person = odbc_fetch_row($rs_person);
			$c[$_POST["t".$i]]= odbc_result($rs_person,"name");
			//$c[$_POST["t".$i]]=$person['name'];
		  }
		  
		  for($i=1;$i<=count($_POST);$i++){
				echo $c[$i]."<br>";		
		  }
		  
		  for($i=1;$i<count($_POST);$i++){
				$con=odbc_connect('db1','','');
				if(isset($_REQUEST["t".$i])){
					echo $sql_command1 = "update Table1 set `order1`=". $_POST["t".$i]." where id=".$i;
				}
				$ok=odbc_exec($con, $sql_command1);
		}
	}
?>

OK, to be honest, I have no idea what you're trying to do here, but I have corrected some things in your code now, although it probably will not work.

As far as i understood, there's a a table "tablename1" with at least two attributes called "id" and "name" in there.

id is a simple number (1, 2, 3 or something like that)
name is any name for a person or something like that.

you are reading all records from this table and order them by the id (ascending) and get the id and name from these records.
Then, you create input fields in the given order from these records, the input fields should be named like "tID", so to speak, the letter "t" is prefixed to the "ID" gathered from the database, f.ex. id 2 will be a textfield with name "t2".

Then you display the name of this id in a link that points to a script 2.php with parameter id=t2 (if we stick to our example from above).

If the user has hit the submit button, you walk through all the post variables to find out what ids have been set in prior.
i changed this a bit and will only consider post variables that start with a "t" and have a number behind that.

You (again) retrieve the name for this id out of the database and fill an associateive array $c with the names of these persons.

Then, you output all the names in the given order to the screen.

Finally, you do some updates on the table tablename1 attribute "order1" with the names you go before, but I don't understand that part.
What should be listed then in "order1"?
How should that look like?

<form name="form" action="2.php" method="post">
<input type="submit" name="submit" id="submit" value="save" /><br />
 
<?php
$con=odbc_connect('try','','');
 
$sql="select * from tablename1 order by id";
$query=odbc_exec($con, $sql);
while (odbc_fetch_row($query))
{       //echo "t".$query['id'];exit;
        $id="t".odbc_result($query,"id");
        $name = odbc_result($query, "name");
        echo '<input type="text" name="' . $id . '" />
                <a href="2.php?id=' . $id . '">' . $name . '</a>
        <br /><br />';
}
if(isset($_POST['submit'])){
  foreach($_POST as $key => $value)
  {
    if(preg_match('/^t[0-9]+/', $key))
    {
      $sql_command = "select name from tablename1 where id=$i";
      $rs_person = odbc_exec($con, $sql_command);
      $person = odbc_fetch_row($rs_person);
      $c[$key]= odbc_result($rs_person,"name");
      echo $c[$key]."<br>";             // echo in this fashion $a[1], $a[2] and so on in the order wise
    }
  }
  foreach($c as $key => $value)
  {
    $sql_command1 = "update tablename1 set `order1`=". $c[$key]." where id=$i";
    $ok=odbc_exec($con, $sql_command1);
     echo "<br>";
   }
  }
?>
</form>

http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/PHP/Q_24365101.html

i am just setting the order of the items to be displayed on the front end and then save that order in the database in the field order1.
