Inserting same id into two tables

Recommended Posts

Hi, hope someone can help.

I have an insert form that I can get information into my database no problem but what I want to do is insert the same id into a seperate table at the same time. I understand that I need to use **mysql_insert_id();** but due to my lack of PHP knowledge I don't know how to use it.

Can anyone help with this please.

Whatever your primary key is that you have set on auto_increment is the id you would enter with the mysql_insert_id(); function.

Try this format, but fill in your values:
$query = "INSERT INTO table1 (value1, value2) VALUES ('$variable1, '$variable2)";
$result = mysql_query($query);
if ($result) {
    $id = mysql_insert_id();
    $new_query = "INSERT INTO table2 (id_colum) VALUES ('$id')";
    $new_result = mysql_query($new_query);
    if ($new_result) {
        echo 'Everything is sucessfull!';
    else {
        echo mysql_error();
else {
    echo myslq_error();

Thanks for the reply.

I've tries to put that into my page and amend the details but still can't get it to work.  My tables are

-id - INT, auto_increment


-id - INT

I'm using dreamweaver and this is the code it's produced to insert the id and title, I just need to know where to put your code to carry the id across to the Text table.

<?php require_once('Connections/dbconnect.php'); ?>
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
  $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
    case "double":
      $theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
  return $theValue;

$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
  $insertSQL = sprintf("INSERT INTO title (title) VALUES (%s)",
                      GetSQLValueString($_POST['title'], "text"));

  mysql_select_db($database_dbconnect, $dbconnect);
  $Result1 = mysql_query($insertSQL, $dbconnect) or die(mysql_error());
