I'm Trying to create a Login form using PHP with the DashDB service from Bluemix, I really dont know whats wrong with this code and I would really appreciate your help! My code is composed of five parts: ConexionDB.php, checklogin.php, login\_success.php, logout.php and main\_login.php

**DashDB Database:**

```
CREATE TABLE MEMBERS (
  ID         INT NOT NULL,
  USERNAME     VARCHAR(65) NOT NULL DEFAULT,
  PASSWORD       VARCHAR(65) NOT NULL DEFAULT,
  PRIMARY KEY (ID)
 );

```

**ConexionDB.php**

```
<?php
// Parse VCAP
if( getenv("VCAP_SERVICES") ) {
    $json = getenv("VCAP_SERVICES");
}
// No DB credentials
else {
    throw new Exception("No Database Information Available.", 1);
}

// Decode JSON and gather DB Info
$services_json = json_decode($json,true);
$bludb_config = $services_json["dashDB"][0]["credentials"];

// Create DB connect string
$conn_string = "DRIVER={IBM DB2 ODBC DRIVER};DATABASE=".
   $bludb_config["db"].
   ";HOSTNAME=".
   $bludb_config["host"].
   ";PORT=".
   $bludb_config["port"].
   ";PROTOCOL=TCPIP;UID=".
   $bludb_config["username"].
   ";PWD=".
   $bludb_config["password"].
   ";";

?>

```

**main\_login.php**

```
<!DOCTYPE HTML>

<html>
    <head>
        <title>Application Name</title>
    </head>
    <body>

<table width="300" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC">

<form name="form1" method="post" action="checklogin.php">

<td><input type="submit" name="Submit" value="Login"></td>

</table>
</td>
</form>
</tr>
</table>

    </body>
</html>

```

**checklogin.php**

```
<?php

//Include DB conexion
require('includes/ConexionDB.php');

$tbl_name="MEMBERS"; // Table name

// username and password sent from form
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];

// Connect to BLUDB
$conn = db2_connect($conn_string, '', '');
if ($conn) {

    // Prepare, execute SQL and iterate through resultset
    $sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";

    $stmt = db2_prepare($conn, $sql);
    $result = db2_execute($stmt);

//$result=db2_query($sql);

?>

<?php

// DB2_num_row is counting table row
$count=db2_num_rows($result);

// If result matched $myusername and $mypassword, table row must be 1 row

if($count==1){

// Register $myusername, $mypassword and redirect to file "login_success.php"

session_register("myusername");
session_register("mypassword");
header("location:login_success.php");
}
else {
echo "Wrong Username or Password";
}

?>

<?php
    db2_close($conn);
}
?>

```

**login\_success**

```
// Check if session is not registered, redirect back to main page.
// Put this code in first line of web page.
<?php
session_start();
if(!session_is_registered(myusername)){
header("location:main_login.php");
}
?>

<html>
<body>
Login Successful
</body>
</html>

```

**logout**

```
// Put this code in first line of web page.
<?php
session_start();
session_destroy();
?>

```
