我在這裏有index.php裏面有模態窗口和登錄鏈接。模態窗口是用php在mysql中檢查用戶名和密碼。但是當我點擊提交按鈕 - 不輸入 用戶名或密碼它不顯示PHP錯誤 - '你需要輸入用戶名'或'你需要輸入密碼'...什麼時候刷新index.php,我點擊登錄鏈接它顯示... 如何解決這個問題,首先點擊提交按鈕是爲MySQL的PHP錯誤cheking?登錄模態窗口提交按鈕php
<div id="basic-modal-content">
<div id="winsign">
<form action="" method="post" onSubmit="validate();">
<?php
include 'core/init.php';
if (empty($_POST) === false) {
$username = $_POST['username'];
$password = $_POST['password'];
if (empty($username) === true || empty($password) === true) {
$errors[]= 'You need to enter a username and password';
} else if (user_exists($username) === false) {
$errors[]= 'We cant\'t find username. Have you registered?';
} else if (user_active($username) === false) {
$errors[]= 'You haven\'t acticated your account!';
} else {
$login = login($username, $password);
if ($login === false) {
$errors[] = 'That username/password combination is incorrect';
} else {
$_SESSION['user_id'] = $login;
header('Location: sign_in.php');
exit();
}
}
print_r($errors);
}
?>
<span id="tpos">Username:</span><br>
<input type="text" name="username" class="sbutton" id="modalbox" placeholder="Username">
<br><br><span id="tpos">Password:</span>
<br><input type="password" name="password" class="sbutton" id="modalbox" placeholder="Password">
<br><br><input type="checkbox" name="checkbox" class="cbutton"><span id="ttext">Remember me</span>
<br><input type="submit" value="Sign In" name="signin" id="bsubmit">
</input>
</form>
這是模態窗口,當我點擊提交按鈕,也不是檢查在第一次點擊PHP錯誤,並重新加載的index.php當我點擊第二次是沒有錯誤,但在第一次點擊是不顯示的錯誤,並重新加載頁索引...
深受你的代碼來看,我想說的問題是第6行 –
