Question

我正在尝试制作一个隐藏在提交状态的表单，并用感谢信息替换它。我尝试了几件事，但迄今为止没有任何工作。我现在的代码工作得很好。我最终希望错误消息显示在同一页面上以及后退按钮。我现在正在努力。祝我好运！感谢您提前提供的所有帮助，你们总是很棒！

这是我的php

<? php
if (isset($_POST['email'])) {
    $email_to = "stormygurl73@yahoo.com";
    $email_subject = "Your email subject line";

    function died($error) {
        echo "We are very sorry, but there were error(s) found with the form you submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        echo "Please go back and fix these errors.<br /><br />";
        die();
    }
    // validation expected data exists
    if (!isset($_POST['first_name']) || !isset($_POST['last_name']) || !isset($_POST['email']) || !isset($_POST['telephone']) || !isset($_POST['comments'])) {
        died('We are sorry, but there appears to be a problem with the form you submitted.');
    }
    $first_name = $_POST['first_name']; // required
    $last_name = $_POST['last_name']; // required
    $email_from = $_POST['email']; // required
    $telephone = $_POST['telephone']; // not required
    $comments = $_POST['comments']; // required
    $error_message = "";
    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
    if (!preg_match($email_exp, $email_from)) {
        $error_message. = 'The Email Address you entered does not appear to be valid.<br />';
    }
    $string_exp = "/^[A-Za-z .'-]+$/";
    if (!preg_match($string_exp, $first_name)) {
        $error_message. = 'The First Name you entered does not appear to be valid.<br />';
    }
    if (!preg_match($string_exp, $last_name)) {
        $error_message. = 'The Last Name you entered does not appear to be valid.<br />';
    }
    if (strlen($comments) < 2) {
        $error_message. = 'The Comments you entered do not appear to be valid.<br />';
    }
    if (strlen($error_message) > 0) {
        died($error_message);
    }
    $email_message = "Form details below.\n\n";

    function clean_string($string) {
        $bad = array("content-type", "bcc:", "to:", "cc:", "href");
        return str_replace($bad, "", $string);
    }
    $email_message. = "First Name: ".clean_string($first_name)."\n";
    $email_message. = "Last Name: ".clean_string($last_name)."\n";
    $email_message. = "Email: ".clean_string($email_from)."\n";
    $email_message. = "Telephone: ".clean_string($telephone)."\n";
    $email_message. = "Comments: ".clean_string($comments)."\n";
    $headers = 'From: '.$email_from."\r\n".'Reply-To: '.$email_from."\r\n".'X-Mailer: PHP/'.phpversion();@mail($email_to, $email_subject, $email_message, $headers);
    echo "We have received your enquiry. We will contact you soon.";
} ?>

我只使用基本的联系表格。谢谢你的帮助！

Answer 1

在这种情况下使用会话是好的。您可以在表单提交后设置会话。例如

$_SESSION['IS_FORM_SUBMIT']=true;

在您的视图中，您可以查看：

if(isset($_SESSION['IS_FORM_SUBMIT']) && $_SESSION['IS_FORM_SUBMIT']===true){
    // SHOW FORM
}else{
    //SHOW MESSAGE
}

Answer 2

也可以使用$_GET参数设置重定向。如果我可以给出一点提示：当您验证电子邮件地址时，只需检查“@”和有效字符。您还在检查扩展名，但将来可能会有5个字符或更多的扩展名。

提交后我可以隐藏表格吗？
