Question

Here is my register form:

<p>Please fill out all fields</p><br>

<form method="POST" action="login/login.php">   
<!-- name is the VARIABLE -->
Username: <input type="text" name="username"></br>
Password: <input type="password" name="password"></br>
Email: <input type="text" name="email"></br>    
</form> 
    
</br>
</br>
<form method="POST" action="login/process.php" "> </br>
<input type='submit' value='submit registration'/>
</form>

here is my process.php file:

<?php 
print "<center>";
$Username = $_POST["username"]; 
$Password = $_POST["password"];
$Email  = $_POST["email"];
?>

<?php
include "../shopdb/connection.php";

$query="INSERT INTO USERS (ID, Username, Password, Email) VALUES ('','$Username','$Password','$Email')";

mysql_query($query,$connect);

?>

I keep getting this error:

Notice: Undefined index: username in C:\xampp\htdocs\IIS\login\process.php on line 3

Notice: Undefined index: password in C:\xampp\htdocs\IIS\login\process.php on line 4

Notice: Undefined index: email in C:\xampp\htdocs\IIS\login\process.php on line 5

You are successfully connected to the database.

(the bottom message is a part of the connection script I added to show I’m connected to the DB)..

Any help would be great.

Answer 1

You have your submit button in a form that is separate from the form that your text fields are in. This should work:

<form method="POST" action="login/process.php">
    <!-- name is the VARIABLE -->
    Username: <input type="text" name="username"></br>
    Password: <input type="password" name="password"></br>
    Email: <input type="text" name="email"></br>
    <input type='submit' value='submit registration'/>
</form>

By the way, you should be checking to see if variables exist before you use them:

if(isset($_POST['username'])){
    echo 'Variable is set and I can use it!';
}
