основной вопрос в php

Question

Когда я пытаюсь войти в систему, это не аутентификация - я не возвращаю никаких ошибок. Имя пользователя и пароль находятся в коде (имя пользователя и пароль находятся внутри кода php, который не хранится в базе данных).

Это мой код:

<?php
/* This is the location of the file and will be used as the baseline for all
of my files writing of code within php. */

/*require files for application */
require_once('websiteconfig.inc.php');


define( 'ABSOLUTE_PATH ', '../public_html/cit0215/assignment2/' );


/*This will define my index.php file */
define('URL_ROOT ', 'https://wiki.cit.iupui.edu/~mjcrawle/cit0215/assignment2/index.php/');



/*functions that validate logins */


function validateLogin($emailaddress='', $password='') {
/*Initialized the Variable from the original from the form */
    $email_key = 'betty@abc.com';
    $password_key = '1234'; 
    $auth_match = 0;

    /*This is the first If statement the test username and password*/
    if ($emailaddress == $email_key && $password == $password_key) {
        $auth_match=1;
    }


    /*this is what ensure the username and password are correct*/   
    return $auth_match;
}


function sanitize($form_var){
    $clean_data = strtolower(trim($form_var));
    return $clean_data;
}


/*Authticate the status of logins*/
$auth_status =0;

/*Determine if the form data was submitted*/
if (array_key_exists('submit', $_POST)){
    /*this removes left over data*/
    $emailaddress = sanitize($_POST['emailaddress']);
    $password = sanitize($_POST['password']);

    /*verify form data*/
    $auth_status = validateLogin($emailaddress, $password);
}


include('header/header.inc.php');{
    if($auth_status == 1){
        /*successful logon*/

        echo '<h3>Welcome Back, Betty!...  Your not ugly after all</h3>' . "\n\n";
    echo  '<ul>' . "\n";
    echo "\t" . '<li><a href"' . URL_ROOT . 'onlinebanking" title="Online 

Banking">On Line Banking</a> </li>' . "\n\n";
    echo '</u>';
    }


    elseif($auth_status == 0); {
        /*authentication has failed*/
    echo '<h4>Authentication error please try again! </h4>' . "\n\n";
    echo '<p> Please make sure that the "Numbers lock" or "Caps Lock" is not 

on and re-type your password.</p>'; 
    }


    include('footer_nav/footer.inc.php'); 
}
?>

В вашем коде логические ошибки.

    <?php

    /*used as the baseline for all of my files writing */
    /*of code within php. */
    /*require files for application */

    require_once('websiteconfig.inc.php');

    define( 'ABSOLUTE_PATH ', '../public_html/cit0215/assignment2/' );

    /*This will define my index.php file */
    define( 'URL_ROOT ', 'https://wiki.cit.iupui.edu/~mjcrawle/cit0215/assignment2/index.php/');

            echo '</u>';



// FIXME - ";" do not operation here. Your test for $auth_status do nothing.
        } elseif($auth_status == 0); {
            /*authentication has failed*/
            echo '<h4>Authentication error please try again! </h4>' . "\n\n";
            echo '<p> Please make sure that the "Numbers lock" or "Caps Lock" is not on and re-type your password.</p>'; 
        }

        include('footer_nav/footer.inc.php'); 

    ?>

Много перерывов затрудняют поиск ошибок.

Answer 2

Обратите внимание, что

elseif($auth_status == 0); {
echo '<h4>Authentication error please try again! </h4>' . "\n\n";

плохо отформатирован (и, вероятно, не то, что вы хотите). Он выполняет ; (без операции, т.е. ничего), если $auth_status равен нулю. Вы, вероятно, хотели написать:

if ($auth_status) {
    echo '<h3>Welcome Back, Betty!</h3>';
} else { // or elseif (!$auth_status) { // <-- no semi-colon
    echo '<h4>Authentication error please try again! </h4>' . "\n\n";
}
