Хорошо, поэтому я пишу фрагмент кода, который проверяет ряд условий, установленных в операторах IF, чтобы отобразить кнопку для регистрации на веб-сайте. Однако переменные, которые я объявляю как истинные/ложные в своих операторах IF, похоже, не переносятся в оператор, в котором определяется, все ли они истинны. Я посмотрел в Интернете и нигде не нашел такой проблемы, поэтому я не знаю, глупо ли это или есть настоящая проблема. Вот мой код:
<?php
include_once('db_conx.php');
//CHECKING USERNAME IS NOT TAKEN
if(!empty($_POST["username"])) {
$usernameAuth = false;
$username = $_POST['username'];
$sql = "SELECT * FROM users WHERE username='$username'";
$queryUname = mysqli_query($conn, $sql);
$username_check = mysqli_num_rows($queryUname);
if($username_check>0){
echo "Username Not Available.";
} else {
echo "Username Available.";
$usernameAuth = true;
}
}
//CHECKING EMAIL HAS NOT BEEN USED BEFORE
if(!empty($_POST["email"])) {
$emailAuth = false;
$email = $_POST['email'];
$sql = "SELECT * FROM users WHERE email='$email'";
$queryEmail = mysqli_query($conn, $sql);
$email_check = mysqli_num_rows($queryEmail);
if($email_check>0){
echo "Email already registered.";
} else {
$emailAuth = true;
}
}
//CHECKING THAT THE PASSWORDS MATCH AND ARE VALID
if(!empty($_POST["password1"]) && !empty($_POST["password2"])) {
$passAuth = false;
$password1 = $_POST['password1'];
$password2 = $_POST['password2'];
if($password1 != $password2) {
echo "Your passwords do not match.";
} elseif(!preg_match("#[0-9]+#",$password1)) {
echo "Your Password Must Contain At Least 1 Number!";
} elseif(!preg_match("#[A-Z]+#",$password1)) {
echo "Your Password Must Contain At Least 1 Capital Letter!";
} elseif(!preg_match("#[a-z]+#",$password1)) {
echo "Your Password Must Contain At Least 1 Lowercase Letter!";
} else {
$passAuth = true;
}
}
//CHECKING TO SEE IF ALL THE VALIDATION CONDITIONS ARE MET
if(!empty($_POST["checkinput"])){
if(($usernameAuth) && ($emailAuth) && ($passAuth)){
echo '<button id="button" class="btn waves-effect waves-light" type="submit" onclick="signup()" name="action">Register<i class="material-icons right">send</i></button>';
} else {
echo 'shite';
}
}
?>
