Adding values to insert query [was: Plz help with this code]

Question

I have created a comments section in which there is only one field comment here is the code of the form:
<form id="frmComment" name="frmComment" method="POST" action="<?php echo $editFormAction; ?>">
    <h3>
      <label for="namegd"></label>Comment:</h3>
    <p>
      <label for="comment2"></label>
      <textarea name="comment" id="comment2" cols="60" rows="10" ></textarea>
    </p>
    <p>
      <label for="submit">
      </label>
      <input type="submit" name="submit" id="submit" value="Submit" />
      <label for="reset"></label>
      <input type="reset" name="reset" id="reset" value="Clear" />
    </p>
<input type="hidden" name="MM_insert" value="frmComment" />
</form>
and the insert into code applied to the form is this
$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "frmComment")) {
  $insertSQL = sprintf("INSERT INTO comments (`comment`, ) VALUES (%s)",
                       GetSQLValueString($_POST['comment'], "text"));
  mysql_select_db($database_my_connection, $my_connection);
  $Result1 = mysql_query($insertSQL, $my_connection) or die(mysql_error());
But I want the form to insert two more values to the database one will be the commented_by and the other will be post_id where commented_by = ($_SESSION['Username']) and post_id = $row_Recordset1['id'] can some one plz let me know what will be the modified code and ya commented_by is a text field and post_id is an int field.
Plz guys help me Thanks in advance

Answer 1

Adding the extra values to the insert query is easy:
$insertSQL = sprintf("INSERT INTO comments (`comment`, commented_by, post_id) VALUES (%s, %s, %s)",
         GetSQLValueString($_POST['comment'], "text"),
         GetSQLValueString($_SESSION['Username'], "text"),
         GetSQLValueString($row_recordset1['id'], "int"));
You need to make sure that the code for recordset1 comes before the insert query. By default, Dreamweaver places recordset code immediately above the DOCTYPE declaration, and below other server behaviors. So, you need to move the code. Otherwise, this insert query won't work.
