I’m working on a registration form for my website.
One of the fields on my registration form is a drop down box that is populated by a table on my MySQL database.
I originally wrote the registration script a different way but I needed to change how the form worked to accommodate the new drop down box and the way it gathered its data.
Before the changes the form was successfully submitted, but now it just gives me a white screen.
I have checked the mysqli_connect.php with an if-else statement. It showed that it was working but no registrations were being sent to the MySQL server when the submit button was pressed. Also, the drop down box was not showing any of the content from the MySQL table that it was linked to.
Below is a copy of the script that I am using:
<?php
@ini_set('display_errors', 'on');
echo "<h1>Register</h1>";
if ($_SERVER['REQUEST_METHOD'] == 'POST'){
$errors = array();
if (empty($_POST['firstname'])){
$errors[] = 'Your forgot to enter your first name.';
}else{
$firstname = trim($_POST['firstname']);
}
if (empty($_POST['lastname'])){
$errors[] = 'Your forgot to enter your last name.';
}else{
$lastname = trim($_POST['lastname']);
}
if (empty($_POST['username'])){
$errors[] = 'Your forgot to enter your username.';
}else{
$username = trim($_POST['username']);
}
if (!empty($_POST['password1'])) {
if ($_POST['password1'] != $_POST ['password2']) {
$errors[] = 'Your password did not match the confirmed password!';
}else{
$password = trim($_POST['password1']);
}
} else {
$errors[] = 'You forgot to enter your password!';
}
if (empty($_POST['birthdate'])){
$errors[] = 'Your forgot to enter your birthdate.';
}else{
$birthdate = trim($_POST['birthdate']);
}
if (empty($_POST['gamespyid'])){
$errors[] = 'Your forgot to enter your gamespy id.';
}else{
$gamespyid = trim($_POST['gamespyid']);
}
if (empty($errors)) {
require ('mysqli_connect.php');
$q="INSERT INTO Users (firstname, lastname, username, password1, birthdate, gamespyid, base) VALUES ('$firstname', '$lastname', '$username', SHA1('$password1'), '$birthdate', '$gamespyid', '$base')";
$r = @mysql_query($dbc, $q);
if ($r){
echo'<p>You are now registered</p>';
}else{
echo'<p>You have not been registered</p>';
}
} else {
echo 'Error<br> <p>The following errors have occured:<br/>';
foreach ($error as $msg) {
echo " - $msg<br/>\n";
}
echo '</p><p>Please try again.</p><p><br/></p>';
} //if no errors
} //submit
?>

You can’t require from ‘http’. You need to change
to some local path like
