目前正在尝试构建注册表单我遇到了一个问题，注册工作正常，直到我添加代码来检查字段是否设置正确。
if( !$username12 or !$password12 or !$email or !$habbo ) {
echo "
<div class=\"alert alert-danger\">
<strong>Error!!</strong> Please Try again
</div>"
} else {
$db->query( "INSERT INTO `users`(`id`, `username`, `password`, `email`, `habbo`, `skype`, `location`, `displaygroup`, `usergroups`) VALUES (NULL, '{$username12}', '{$password_enc}', '{$email}', '{$habbo}', '{$skype}', '{$location}', '1', '1')");
echo "
<div class=\"alert alert-success\">
<strong>Success!</strong> Our intern Steven recieved your request!
</div>"
}
?>function SubmitFormRegister() {
var username12 = $("#username12").val();
var password12 = $("#password12").val();
var email = $("#email").val();
var habbo = $("#habbo").val();
var skype = $("#skype").val();
var location = $("#location").val();
$.post("pages/register_submit.php", { username12: username12, password12: password12, email: email, habbo: habbo, skype: skype, location: location },
function(data) {
$('#results').html(data);
$('#myForm')[0].reset();
});
}<!-- register.php -->

这是register_submit.php的代码
<?php
require_once( "../staff/staff/_inc/glob.php" );
$password12 = $_POST['password12'];
$username12 = $_POST['username12'];
$password_enc = $core->encrypt( $password12 );
$email = $_POST['email'];
$habbo = $_POST['habbo'];
$skype = $_POST['skype'];
$location = $_POST['location'];
$query3 = $db->query( "SELECT * FROM users WHERE username = '{$username12}'" );
$array3 = $db->assoc( $query3 );
$query4 = $db->query( "SELECT * FROM users WHERE email = '{$email}'" );
$array4 = $db->assoc( $query4 );
$query5 = $db->query( "SELECT * FROM users WHERE habbo = '{$habbo}'" );
$array5 = $db->assoc( $query5 );
if( !$username12 or !$password12 or !$email or !$habbo ) {
echo "<div class=\"alert alert-danger\"><strong>Error!!</strong> Please Try again</div>"
} else {
$db->query( "INSERT INTO `users`(`id`, `username`, `password`, `email`, `habbo`, `skype`, `location`, `displaygroup`, `usergroups`) VALUES (NULL, '{$username12}', '{$password_enc}', '{$email}', '{$habbo}', '{$skype}', '{$location}', '1', '1')");
echo "<div class=\"alert alert-success\"><strong>Success!</strong> Message! </div>" }?>
如果我删除了If和else标签，则提交工作完全正常，但是在那里，表单将不会提交。不确定我的语法是否有问题，或者是否有其他问题。
先谢谢

我可能错了，但请尝试更换＆＃34;或＆＃34;与||

你没有“;”在echo语句的if块中。
为了消除由引号（“）和转义序列创建的混淆，请使用：
echo
