标签： php forms validation

作为PHP语言的新手我已经设置了一个php联系表单（contact.php），其中包含html编码以及Javascript验证码。完成所有未提交的内容并转到我给出的电子邮件ID。真的，我无法弄清楚问题发生的代码。您能否检查以下代码并帮我解决这个问题？

<?php

// Set email variables
$email_to = 'contact@mycompany.com';
$email_subject = 'New Contact Form Submission';

/* Gathering Data Variables */

    $fullname = $_POST['fullname'];
    $email = $_POST['email'];
    $phone = $_POST['phone'];
    $country = $_POST['country'];
    $message = $_POST['message'];
    $ipaddress = $_POST['ipaddress'];

    $body = <<<EOD
<br><hr><br>
Full Name: $fullname <br>
Email: $email <br>
Phone: $phone <br>
Country: $country <br>
Message: $message <br>
Submitted By IP: $ipaddress <br>
EOD;

    $headers = "From: $fullname\r\n";
    $headers .= "Content-type: text/html\r\n";
    $success = mail($webMaster, $emailSubject, $body,
$headers);

// Set required fields
$required_fields = array('fullname','email','country','message');

// set error messages
$error_messages = array(
    'fullname' => 'Please enter Your Name to proceed.',
    'email' => 'Please enter a valid Email Address to contact.',
    'country' => 'Please enter your country of residence.',
    'message' => 'Please enter your message.'
);

// Set form status
$form_complete = FALSE;

// configure validation array
$validation = array();

// check form submittal
if(!empty($_POST)) {
    // Sanitise POST array
    foreach($_POST as $key => $value) $_POST[$key] = remove_email_injection(trim($value));

    // Loop into required fields and make sure they match our needs
    foreach($required_fields as $field) {       
        // the field has been submitted?
        if(!array_key_exists($field, $_POST)) array_push($validation, $field);

        // check there is information in the field?
        if($_POST[$field] == '') array_push($validation, $field);

        // validate the email address supplied
        if($field == 'email') if(!validate_email_address($_POST[$field])) array_push($validation, $field);
    }

    // basic validation result
    if(count($validation) == 0) {
        // Prepare our content string
        $email_content = 'Contact Form Submission Received: ' . "\n\n";

        // simple email content
        foreach($_POST as $key => $value) {
            if($key != 'submit') $email_content .= $key . ': ' . $value . "\n";
        }

        // if validation passed ok then send the email
        mail($email_to, $email_subject, $email_content);

        // Update form switch
        $form_complete = TRUE;
    }
}

function validate_email_address($email = FALSE) {
    return (preg_match('/^[^@\s]+@([-a-z0-9]+\.)+[a-z]{2,}$/i', $email))? TRUE : FALSE;
}

function remove_email_injection($field = FALSE) {
   return (str_ireplace(array("\r", "\n", "%0a", "%0d", "Content-Type:", "bcc:","to:","cc:"), '', $field));
}

?>

我稍微修改了你的代码。您似乎在验证之前构建了电子邮件。 您可以将所有代码放在一个文件中，而不是两个。

<?php

  // Set email variables
$email_to = 'contact@mycompany.com';
$email_subject = 'New Contact Form Submission';
$ipaddress=$_SERVER['REMOTE_ADDR'];

// Set required fields
$required_fields = array('fullname','email','country','message');

// set error messages
$error_messages = array(
    'fullname' => 'Please enter Your Name to proceed.',
    'email' => 'Please enter a valid Email Address to contact.',
    'country' => 'Please enter your country of residence.',
    'message' => 'Please enter your message.'
);



// check form submittal
if(!empty($_POST)) {


// Sanitise POST array
foreach($_POST as $key=>$value){ 

if($key=="fullname"){$fullname=str_replace( '[at]','@', $value);}
if($key=="country"){$country=str_replace( '[at]','@', $value);}
if($key=="message"){$message=str_replace( '[at]','@', $value);}
if($key=="phone"){$phone=str_replace( '[at]','@', $value);}

if($key=="email"){
if(!filter_var($value, FILTER_VALIDATE_EMAIL)) { $error_out[$key]=$error_messages[$key];} else{$email=$value;}
   }

// check required fields
        if(in_array($key, $required_fields) and empty($value))
        {
             $error_out[$key]=$error_messages[$key]; // errors for required
        }

if($key=="amigura"){$amigura='';}else{$amigura='';}

}

$body = <<<EOD
<br><hr><br>

Email: $email <br>
Phone: $phone <br>

EOD;

//echo $body;   

    // send mail
    if(!$error_out){

$headers  = "MIME-Version: 1.0" . "\r\n";
$headers .= "From: $fullname <$email> \r\n";
$headers .= "Content-type: text/html;charset=UTF-8 \r\n";

    if(mail($email_to, $emailSubject, $body,$headers)){$form_complete='sendme';}

        }
        else
        {$form_complete='';}
