[英]Change the page when pressing a submit button in PHP
When I press the submit button "login" I want my page to go to "frontPage.php", but it goes instead to "login.php" even though I have specified当我按下提交按钮“登录”时,我希望我的页面到 go 到“frontPage.php”,但即使我已经指定,它也会转到“login.php”
header("location: frontPage.php");
in my login.php.在我的登录名中。php。
login.php login.php
if (isset($_POST['login'])) {
if (empty($_POST["username"]) || empty($_POST["password"])) {
echo "Please fill all fields";
} else {
$usernameinput = filter_input(INPUT_POST, "username", FILTER_SANITIZE_STRING);
$passwordinput = filter_input(INPUT_POST, "password", FILTER_SANITIZE_STRING);
$query = "SELECT * FROM users WHERE username = :username";
$stmt = $conn->prepare($query);
$stmt->execute(array(
'username' => $usernameinput
));
$count = $stmt->rowCount();
if ($count > 0) {
while ($result = $stmt->fetch(PDO::FETCH_ASSOC)) {
if (password_verify($passwordinput, $result["password"])) {
$_SESSION["username"] = $usernameinput;
break;
}
}
header("location: frontPage.php");
} else {
header("location: index.php");
}
}
}

You are missing the name attribute on the submit button.您缺少提交按钮上的名称属性。 It should have an attribute of name=“login”.
它应该具有 name="login" 的属性。
All of your inputs are also missing the name attribute.您的所有输入也缺少名称属性。 Copy what you have for id attributes for the missing name attributes.
复制缺少的名称属性的 id 属性。
