Question

我正在制作我的注册表格，如果用户键入正确的验证码，那么用户的数据将被存储到数据库中，如果验证码错误那么它会将输出打印为错误但我的问题是如果用户输入了错误验证码的代码，它将用户的数据存储到数据库中，并显示“错误的代码”输出，请帮助我错了？

这是我的代码。

<?php session_start(); ?>
<?php
// show potential errors / feedback (from registration object)
if (isset($registration)) {
    if ($registration->errors) {
        foreach ($registration->errors as $error) {
            echo '<div class="alert-box error"><span>Error: </span>'.$error.'</div>';
        }
    }
    if ($registration->messages) {
        foreach ($registration->messages as $message) {
            echo '<div class="alert-box success"><span>Success: </span>'.$message.'</div>';
        }
    }
}

/** Validate captcha */
if (!empty($_REQUEST['captcha'])) {
    if (empty($_SESSION['captcha']) || trim(strtolower($_REQUEST['captcha'])) != $_SESSION['captcha']) {
        $captcha_message ="Invalid captcha";
        $style = "background-color: #FF606C color:#555
        border-radius: 0px
        font-family:Tahoma,Geneva,Arial,sans-serif font-size:11px;
        font-size: 18px
        padding:  30px 36px
        margin:10px font-weight:bold
        text-transform:uppercase border:2px solid #0c0b0b
        background-color: #ff7e48 ";

        echo'
        <div id="result" style="$style">
        <h2><div class="alert-box error"><span>error: </span>'.$captcha_message.'</div></h2>
        </div>';

    } else {
        $captcha_message = "Valid captcha";
        $style = "background-color: #CCFF99";
    }


    $request_captcha = htmlspecialchars($_REQUEST['captcha']);
    unset($_SESSION['captcha']);
}
?>

简单的例子，删除register.php并在Else上添加有关数据库的信息，如果验证码是正确的。

/** Validate captcha */
if (!empty($_REQUEST['captcha'])) {
    if (empty($_SESSION['captcha']) || trim(strtolower($_REQUEST['captcha'])) != $_SESSION['captcha']) {
        $captcha_message ="Invalid captcha";
        $style = "background-color: #FF606C color:#555
        border-radius: 0px
        font-family:Tahoma,Geneva,Arial,sans-serif font-size:11px;
        font-size: 18px
        padding:  30px 36px
        margin:10px font-weight:bold
        text-transform:uppercase border:2px solid #0c0b0b
        background-color: #ff7e48 ";

        echo'
        <div id="result" style="$style">
        <h2><div class="alert-box error"><span>error: </span>'.$captcha_message.'</div></h2>
        </div>';

    } else {
        $captcha_message = "Valid captcha";
        $style = "background-color: #CCFF99";
       //insert in database here and redirect to index or profil
    }
    $request_captcha = htmlspecialchars($_REQUEST['captcha']);
    unset($_SESSION['captcha']);
}

并替换

<form id="form_box" method="post" action="register.php" name="registerform">

带

<form id="form_box" method="post" action="" name="registerform">

我的验证码没有进入我的注册表格
