删除iframe后，联系人表单在浏览器中显示PHP

我想重用/重新设计一个我以前使用过的php表单，但是使用了一个调用php文件的iframe。我被告知这是一种不好的做法，并停止使用iFrame；但是，当我将php移动到html页面时，php代码显示在表单的文本字段中

我在这里检查了几页的php线程，似乎问题通常是忘记关闭php标记或者主机不支持php。我没有改变php本身的工作版本，我的主机支持php版本5.3.6

编辑：将文件更改为.php清除了浏览器中的php，但表单不会发送

文本字段中显示的PHP如下所示：

<?php echo ($sr && !$cf['form_ok']) ? $cf['posted_form_data']['name'] : '' ?>
<?php echo ($sr && !$cf['form_ok']) ? $cf['posted_form_data']['email'] : '' ?>
<?php echo ($sr && !$cf['form_ok']) ? $cf['posted_form_data']['message'] : '' ?>

Contact.html页面代码：

    <div id="contact-form" class="clearfix">

<?php session_start(); ?>
<?php
include("spam_check.php");
?>
            <h2> You can contact us by filling out the form below.</h2>
            <?php
            //init variables
            $cf = array();
            $sr = false;

            if(isset($_SESSION['cf_returndata'])){
                $cf = $_SESSION['cf_returndata'];
                $sr = true;
            }
            ?>
            <ul id="errors" class="<?php echo ($sr && !$cf['form_ok']) ? 'visible' : ''; ?>">
                <li id="info">There were some problems with your form submission:</li>
                <?php 
                if(isset($cf['errors']) && count($cf['errors']) > 0) :
                    foreach($cf['errors'] as $error) :
                ?>
                <li><?php echo $error ?></li>
                <?php
                    endforeach;
                endif;
                ?>
<?php
if (isset($_POST['real'])) {
  // error condition, redisplay form
}
?>
            </ul>
            <p id="success" class="<?php echo ($sr && $cf['form_ok']) ? 'visible' : ''; ?>">Thanks for your message! We will get back to you ASAP!</p>
            <form method="post" action="process.php">
                <label for="name">Name: <span class="required">*</span></label>
                <input type="text" id="name" name="name" value="<?php echo ($sr && !$cf['form_ok']) ? $cf['posted_form_data']['name'] : '' ?>" placeholder="Your Name" required autofocus />

                <label for="email">Email: <span class="required">*</span></label>
                <input type="email" id="email" name="email" value="<?php echo ($sr && !$cf['form_ok']) ? $cf['posted_form_data']['email'] : '' ?>" placeholder="yourname@example.com" required />

                <label for="message">Message: <span class="required">*</span></label>
                <textarea id="message" name="message" placeholder="Your message must be greater than 20 characters." required data-minlength="20"><?php echo ($sr && !$cf['form_ok']) ? $cf['posted_form_data']['message'] : '' ?></textarea>

<label style="display:block;position:absolute;left:-9999px" class="real">
  Please leave this checkbox blank
  <input type=checkbox name=real value=1>
</label>

                <span id="loading"></span>
                <input type="submit" value="SEND" id="submit-button" />
                <p id="req-field-desc"><span class="required">*</span> indicates a required field</p>          
            </form>

            <?php unset($_SESSION['cf_returndata']); ?>
        </div>

查看页面源代码-其他PHP代码也在那里吗？如果php不能正常工作，那么所有的代码都会显示出来，而不仅仅是表单字段中的一些位

你说你把它移到了一个“html文件”。那是“somefile.html”吗？请记住，Web服务器通常不会将.html设置为由PHP解析。尝试将其重命名为“somefile.php”。
是的，我可以查看源代码中的所有php。我将文件改为.php，现在看起来一切都很好，尽管我发了一封从未收到的测试电子邮件。我最初搜索是为了看看在html页面中植入php是否合适。我遇到的结果只是简单地说总是包括我在开始时仍然调用html doctype有关系吗？与doctype无关，一切都与Web服务器不会通过PHP解释器传递.html文件这一事实有关，除非您告诉它。好的。我只是想弄明白为什么表单现在显示正确，但不会提交。在原始帖子中添加了Process.php。我想知道我是否应该尝试将所有内容都保存在自己的php文件中，然后插入一个动作以html形式调用php文件？我一到家就试试这个。你可以用任何你想用的东西作为动作，例如，发到JPG，但不会有什么效果。没有理由不能在.html页面中使用表单并将其发布到php脚本。
