Object Expected...how do i fix it?

i'm trying to retrieve the contents of a textfield, parse it into 2 fields and then insert into the database...again syntax errors.
this is what i have:

<?php
     if($rows = @mysql_fetch_array($result))
     {
        echo "<BR><BR><BR><FONT SIZE=2>Found the following results for <B>'";
        echo $_POST['searchfield'];
        echo "'</B> in <B>'$stype'</B> field:<BR><BR>";

	    echo '<TABLE BORDER="1" CELLPADDING="4" CELLSPACING="2">';
	    echo '<TR><TD><B><FONT SIZE=2>Last Name</B></TD><TD><B><FONT SIZE=2>First Name</B></TD><TD><B><FONT SIZE=2>User Id</B></TD><TD><B><FONT SIZE=2>Privileges</B></TD></TR>';

	    extract($rows);
        echo "<TR><TD><FONT SIZE=2>$lastname</TD><TD><FONT SIZE=2>$firstname</TD><TD><FONT SIZE=2>$userid</TD><TD><FONT SIZE=2>$privileges</TD></TR>";

    	while($rows = @mysql_fetch_array($result))
        {
    	   extract($rows);
           echo "<TR><TD><FONT SIZE=2>$lastname</TD><TD><FONT SIZE=2>$firstname</TD><TD><FONT SIZE=2>$userid</TD><TD><FONT SIZE=2>$privileges</TD></TR>";
    	}
    	echo '</TABLE>'; 
        mysql_free_result($result);           
     }
     else
     {
        echo "<BR><BR><FONT SIZE=2>No entries found for <B>'";
	    echo $_POST['searchfield'];
        echo "'</B> in <B>'$stype'</B> field.<BR>";
        echo "<FONT SIZE=2>Try using '*' for wildcard searching.<BR><BR>";
        echo "<B><FONT SIZE=2>OR<BR><BR></B>";
        echo "<FONT SIZE=2>Add New User  ";
        echo '<INPUT TYPE="text" ID="newuser" NAME="newname" VALUE="" SIZE="30" STYLE="display:none;"/>';
        echo '<BR><BR><INPUT TYPE=button NAME="submitnewuser" VALUE=" Add " ONCLICK="addNewUser();">';
     }
?>
<SCRIPT LANGUAGE="Javascript" TYPE="text/javascript">
   document.getElementById('newuser').style.display='';
   document.getElementById('newuser').focus();    
</SCRIPT>

<?php     
     include('./searchgoback.inc'); 
     mysql_close();
  }
  else
  {
     include('./searchusers.inc');
  }

?>
<SCRIPT LANGUAGE="Javascript" TYPE="text/javascript">
  function addNewUser()
  {    
      var $firstname;
      var $lastname;
      $newUser = document.getElementById('newuser').value;
      <?php $str = sscanf($newUser, "%s %s", $firstname, $lastname); ?>
      <?php $query = "INSERT INTO awacsuser(firstname, lastname) VALUES ('$firstname', '$lastname')"; ?>
  }

</SCRIPT>

Code (markup):

i'm getting
Undefined variable: newUser in this line:
$newUser = document.getElementById('newuser').value;


and object expected on the addNewUser() call.

 

$newUser = document.getElementById('newuser').value;

you doing some javascript and php.
while its fine for me

getelementbyid is used for an id=
you need document.myformname.newuser.value

but
this normally(use javascript) is done before the form is processed to see if the values are filled for better user experience.

but use php to process and also validate it (again)
$username=$_POST['newuser'];

goodluck

you n

 

You can't mix javascript with PHP.........
