PHP:

$errors = array();

$db = "";



if (isset($_POST['saveuserForm'])) {
    $host = $_POST['host'];
    $username = $_POST['username'];
    $password = $_POST['password'];

    if($host == "") {
        $errors[] = "Host can not be blank";

    if($username == "") {
        $errors[] = "Username can not be blank";
    }
    if($password == "") {
        $errors[] = "Password can not be blank";
    }
    if($databasename == "") {
        $errors[] = "Database Name can not be blank";
    }


    if ($host !== "" && $username !== "" && $password !== "" && $databasename !== "") {
            $db = mysqli_connect($host, $username, $password, $databasename);
            $connectionstring = "
            <?php
                \$dbname = \"d" . $databasename . "\";
                \$dbuser = \"w" . $username . "\";
                \$dbpass = \"f" . $password . "\";
                \$dbhost = \"s" . $host . "\";
                \$db = mysqli_connect(\$dbhost, \$dbuser, \$dbpass, \$dbname );


                if (mysqli_connect_errno()) {
                        echo \"Failed to connect to MySQL: \" . mysqli_connect_error();
                }
            ";

        echo file_put_contents("../includes/dbname.php", $connectionstring);

    }
    }

HTML:

<ul>
<?php
foreach ($errors as $value) {
    echo "<li>$value</li>";
}
?>
</ul>


<form action="install.php" method="post">
