No database selected error

[mev9669]

Hi,

I am very new to PHP and trying to write a small bit of code to insert a record to the database. The code gives me a No database Selected error. I have tried to check the connection to the database and it does get connected. 

Thanks for your help in advance

PHP Code: [Select]



<?php require_once('../Connections/connect.php'); ?>
<?php

$today = date("Y-m-d H:i:s");


if ($_POST['form_submitted'] == '1') {
##User is registering, insert data until we can activate it

$activationkey =  mt_rand().mt_rand();
$user_name = mysql_real_escape_string($_POST[user_name]);
$user_last = mysql_real_escape_string($_POST[user_last]);
$user_pass = mysql_real_escape_string (md5($_POST[user_pass]));

$user_email = mysql_real_escape_string($_POST[user_email]);
$telephone = mysql_real_escape_string($_POST[telephone]);


$sql="INSERT INTO local_advertisers (user_name, user_last, user_pass, user_email, telephone, registerdate, activationkey, registrationstatus) VALUES ('$user_name', '$user_last', '$user_pass', '$user_email', '$telephone', '$today', '$activationkey', 'verify')";


if (!mysql_query($sql))

  {

  die('Error: ' . mysql_error());

  }

?>

What's in /Connections/connect.php?

You need to connect to the database with a valid username/password and select the database you want to use.

From php.net

PHP Code: [Select]

<?php

$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
    die('Not connected : ' . mysql_error());
}

// make foo the current db
$db_selected = mysql_select_db('foo', $link);
if (!$db_selected) {
    die ('Can\'t use foo : ' . mysql_error());
}
?>

The error tells you what's wrong.... check your conenct.php

My connect. php contains the following. the connect to the database does work as I am able to connect to the database and do a select query.

connect. php

PHP Code: [Select]


<?php
# FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"
$hostname_connect = "localhost";
$database_connect = "Mydatabase";
$username_connect = "username";
$password_connect = "password";
$connect = mysql_pconnect($hostname_connect, $username_connect, $password_connect) or trigger_error(mysql_error(),E_USER_ERROR); 
?>

You're connecting the database server but not opening a database to use. Notice your unused $database_connect variable.


Try adding this to bottom of your existing code:

PHP Code: [Select]

$db_selected = mysql_select_db($database_connect, $connect);
if (!$db_selected) {
    die ('Can\'t use foo : ' . mysql_error());
}

Still does not work.

I have a login with the same connection and it worked without the code you mentioned to be added in the connect.php

the below is my login.php

PHP Code: [Select]

<?php require_once('../Connections/connect.php'); ?>
<?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";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}
?>
<?php
// *** Validate request to login to this site.
if (!isset($_SESSION)) {
  session_start();
}

$loginFormAction = $_SERVER['PHP_SELF'];
if (isset($_GET['accesscheck'])) {
  $_SESSION['PrevUrl'] = $_GET['accesscheck'];
}

if (isset($_POST['user_email'])) {
  $loginUsername=$_POST['user_email'];
  $password=md5($_POST['user_pass']);
  $MM_fldUserAuthorization = "";
  $MM_redirectLoginSuccess = "/event-advertising/myaccount/";
  $MM_redirectLoginFailed = "/event-advertising/login.php";
  $MM_redirecttoReferrer = false;
  mysql_select_db($database_connect, $connect);
  
  $LoginRS__query=sprintf("SELECT user_email, user_pass FROM local_advertisers WHERE user_email=%s AND user_pass=%s",
    GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text")); 
   
  $LoginRS = mysql_query($LoginRS__query, $connect) or die(mysql_error());
  $loginFoundUser = mysql_num_rows($LoginRS);
  if ($loginFoundUser) {
     $loginStrGroup = "";
    
    //declare two session variables and assign them
    $_SESSION['MM_Username'] = $loginUsername;
    $_SESSION['MM_UserGroup'] = $loginStrGroup;

      

    if (isset($_SESSION['PrevUrl']) && false) {
      $MM_redirectLoginSuccess = $_SESSION['PrevUrl'];

    }
    header("Location: " . $MM_redirectLoginSuccess );
  }
  else {
    header("Location: ". $MM_redirectLoginFailed );
  }
}

In the login.php you are using the code

PHP Code: [Select]

 mysql_select_db($database_connect, $connect); to select database. Same code you need to use this code while inserting record also
