Question

我一直在浏览互联网，但我找不到任何类似的帖子。问题是我总是使用filter_input(INPUT_SERVER, "REQUEST_METHOD");来获取表单是否已提交，但今天我正在开发一个登录系统，在使用PHP时行为奇怪，在这里你有我实际使用的代码：

$email = filter_input(INPUT_POST, "email");
$pass = filter_input(INPUT_POST, "pass");

print "done0";
if(filter_input(INPUT_SERVER, "REQUEST_METHOD") != "POST") {
    return;
}
print "done1";
if(!isset($email) || !isset($pass)) {
    return;
}
print "done2";

HTML一：

<form action="#" method="POST" accept-charset="UTF-8" autocomplete="off" class="col s12">

    <div class="row">
        <div id="login-panel">

            <div class="col s12">
                <h2 class="white-text center-align">System sign-in</h2>
            </div>
            <div class="input-field col s12">

                <i class="material-icons prefix white-text">email</i>
                <input type="email" name="email" class="validate white-text" autofocus required>
                <label for="email" id="email-label"
                       data-error="You must provide a correct email (example: name@domain.com)">Your email</label>

            </div>
            <div class="input-field col s12">

                <i class="material-icons prefix white-text">visibility_off</i>
                <input type="password" name="password" class="validate white-text" required>
                <label for="pass">Your password</label>

            </div>
            <div class="input-field col s12">
                <button class="btn waves-effect waves-light" id="login-button" type="submit" name="action">Submit
                    <i class="material-icons right">send</i>
                </button>
            </div>

        </div>
    </div>

</form>

最后，我使用具体化API 和 JQuery 2.1.1

希望有人可以帮助我，谢谢！

Answer 1

这是由于您的PHP版本确保您是5.5.15或以上

我认为你应该参考PHP filter_input(INPUT_SERVER, 'REQUEST_METHOD') returns null?

检查提交的表格（方法POST）是否有效
