Question

如何将错误消息从html_form_send.php重定向回我的email.php页面。这是我得到的，我有我的表格email.php：

email.php

<form name = 'htmlform' action = '$template/html_form_send.php' 
      method = 'post' class = 'form-horizontal well' >

我的email.php链接到我的html_form_send.php，其中包含以下代码：

html_form_send.php

<?php
    if(isset($_POST['email'])) {

    // CHANGE THE TWO LINES BELOW
    $email_to = "my email";
    $email_subject = "my subject";

    function died($error) {
        // your error code can go here
        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($_POST['name']) || !isset($_POST['email']) ||
        !isset($_POST['telephone']) || !isset($_POST['password'])) {
        died('We are sorry, but there appears to be a problem \
            with the form you submitted.');       

        // and instead redirect the user to your error page
        header("Location: http://hurstblog.co.uk/contact-error");
    }

    $name = $_POST['name']; // required
    $email_from = $_POST['email']; // required
    $telephone = $_POST['telephone']; // not required
    $password = $_POST['password']; // 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($string_exp,$name)) {
        $error_message .= 'The First Name you entered does not \
            appear to be valid.<br />';
    }
    if (strlen($telephone) < 2) {
        $error_message .= 'The telephone you entered do not \
            appear to be valid.<br />';
    }
    if (strlen($password) < 2) {
        $error_message .= 'The password you entered do not \
            appear to be valid.<br />';
    }
    if (strlen($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);
    }

    $email_message .= "Name: " . clean_string($name) . "\n";
    $email_message .= "Email: " . clean_string($email_from) . "\n";
    $email_message .= "Telephone: " . clean_string($telephone) . "\n";
    $email_message .= "Password: " . clean_string($password) . "\n";

    // create email headers
    $headers = 'From: ' . $email_from . "\r\n".
    'Reply-To: ' . $email_from . "\r\n" .
    'X-Mailer: PHP/' . phpversion();
    @mail($email_to, $email_subject, $email_message, $headers);  

    if (mail($email_to, $email_subject, $email_message, $headers)) {
        header("Location: http://domain.net");
    }
}
die();

?>

我的问题是如何重定向错误？

Answer 1

html_form_send.php

// validation expected data exists
if(!isset($_POST['name'])){
    header("location: email.php?error=name");
}
if(!isset($_POST['email'])){
    header("location: email.php?error=email");
}
if(!isset($_POST['telephone'])){
    header("location: email.php?error=telephone");
}
if(!isset($_POST['password'])){
    header("location: email.php?error=password");
}

$name = $_POST['name']; // required
$email_from = $_POST['email']; // required
$telephone = $_POST['telephone']; // not required
$password = $_POST['password']; // required

$email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$email_from)) {
    header("location: email.php?error=invalid_email");
}
$string_exp = "/^[A-Za-z .'-]+$/";
if(!preg_match($string_exp,$name)) {
    header("location: email.php?error=invalid_firstname");
}
if(strlen($telephone) < 2) {
    header("location: email.php?error=invalid_telephone");
}
if(strlen($password) < 2) {
    header("location: email.php?error=invalid_password");
}

$ _GET ['error']将包含错误ID，因此在您的email.php中，您应该输入错误消息。

$error_message = "";
if($_GET['error']=='invalid_email'){
    $error_message .= 'The Email Address you entered does not appear to be valid.<br />';
}
if($_GET['error']=='invalid_firstname'){
    $error_message .= 'The First Name you entered does not appear to be valid.<br />';
}

//等

if(strlen($error_message) > 0) {
    echo($error_message);
}

我一直在做的是获取错误代码或将验证页面上的错误文本分配给会话变量，然后在您希望用户查看变量的页面上回显该会话变量。不要忘记包含session_start（）;在每页的开头虽然！
