Answer 1

首先，您根本没有在任何地方呼叫registerFunction() ..

只需像这样重写你的SignUp.php

<?php

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    $uname = $_POST['userName'];
    $pword = $_POST['password'];
    $errorMessage;
    $uname = htmlspecialchars($uname);
    $pword = htmlspecialchars($pword);
    $uLength = strlen($uname);
    $pLength = strlen($pword);
    if($uLength >= 0 && $uLength <= 10)
    {
        $errorMessage = "UserName Length";
    }
    else
    {$errorMessage = "No error in UserName Length";
    }
    if($pLength >= 0 && $pLength <= 10)
    {
        $errorMessage = "password Length";
    }
    else
    {$errorMessage = "No error in password Length";
    }
    if(strlen($errorMessage) == "")
    {
        echo "There is no error::::NO Error Message" .$errorMessage;
    }
    else
    {
        echo "There is error::::Error Message" .$errorMessage;
    }
}

您需要致电registerFunction()函数 SignUp.php

无法调用PHP格式的Action中定义的“SignUp.php”页面函数？
