I have a MySQL database called school that is set up like this: schoolID(1), schoolName(school 1), schoolCounty(Buckinghamshire), schoolUsername(school1admin), schoolPassword(school1password)
I currently have a drop down menu that shows the list of schools and when I type any username and password into the HTML login form I can log in.
I can't seem to work out how I can set it so, depending on the school selection will depend on what username and password to use.
For example, if i select school1 then i can ONLY use school1's username and password.
This is what I have so far for index.php:
<?php
require_once 'databaseConnect.php'; // connects to the databse via this file
if ($conn->connect_error) die ($conn->connect_error); // check the connection to the database. If failed, display error
$sql = "SELECT * FROM school";
$result = $conn->query($sql);
$conn->close();
?>
<html>
<body>
<title>EduKode</title>
<div id="login-form-container">
<p>Log In:</p>
<?php
echo'<div id="schoolSelection">';
echo '<select name="schoolName">';
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo '<option>'. $row["schoolName"]. "<br>";
}
} else {
echo "0 results";
}
echo '</select>';
echo'</div>';

<form id="login-form" name="contactform" method="post" action="checkSchoolCredentials.php"> <!-- when submitting the form will call the 'authenticate.php' script.-->
<div class="contact-form">
<label>Username:</label>
<input name="username" type="text"> <!-- students created username field-->
<label>Password:</label>
<input name="password" type="password"> <!-- students created password field-->
</div>
<div id="submit-button">
<input type="submit" name="submit" value="Log In">
</div>
</form>
</div>
</body>
</html>
This is for checkSchoolCredentials.php:
<?php
require_once 'databaseConnect.php'; // connects to the databse via this file
if ($conn->connect_error) die ($conn->connect_error); // check the connection to the database. If failed, display error
if(isset($_POST['submit'])) // if submit button is pressed
{
$username = $_POST['username']; //assigns the value of the input box username to $username
$password = $_POST['password']; //assigns the value of the input box password to $password
$query = "SELECT * FROM school WHERE schoolUsername='$username' AND schoolPassword ='$password'"; // Query the database
$result=mysqli_query($conn, $query);
if(mysqli_num_rows($result) ==1)
{
session_start(); // start session
$_SESSION['auth']='true';
$_SESSION['username'] = $username; // save session as username
header('location:taskSelection.php'); // if correct, redirect to taskSelection.php
}
else
{
header('location:index.php'); // redirect to index.html if incorrect
}
}
$conn->close();
?>
