将多个电子邮件地址添加到 php 电子邮件表单

Question

我为我网站的联系我们页面创建了一个 php 电子邮件表单，并希望对多个电子邮件地址使用相同的表单。但是，当我将代码复制到新页面并添加不同的电子邮件地址时，它会转到与原始联系表单相同的电子邮件地址。

我换了

$email_to = 'example@gmail.com, customer@website.com';

到另一个电子邮件地址，但它不起作用，并继续发送到原始电子邮件地址。

如何使此表单可用于多个电子邮件表单的多个电子邮件？

<?php

// Set email variables
$email_to = 'SARAI.ROMEROEVANS@lausd.net, customer@website.com';
$email_subject = 'Contact Form Submission Bancroft Website';

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

// set error messages
$error_messages = array(
    'fullname' => 'Please enter a Name to proceed.',
    'email' => 'Please enter a valid Email Address to continue.',
    'comment' => 'Please enter your Message to continue.'
);

// 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 = 'New Website Comment: ' . "\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));
}

?>

如果您需要更多代码，请告诉我

据我所知，您不能在 mail() 函数的第一个参数中指定多个电子邮件地址。编辑 - 你可以，但我认为这是不可能的，因为它在过去引起了我的问题。

这是您的代码的编辑版本。我用逗号将 $email_to 分开，然后遍历每个电子邮件地址以向每个电子邮件地址发送电子邮件。

我还添加了一些 if 语句来控制收件人是谁。如果您要为多个表单重复使用代码，则将formID 作为隐藏字段传递，然后您可以在 PHP 中指定应该接收电子邮件的人。无需为每个表单复制 PHP 代码...

<?php

// Set email variables

if($_POST['formID'] == 1) {
    $email_to = 'SARAI.ROMEROEVANS@lausd.net, customer@website.com';
} elseif($_POST['formID'] == 2) {
    $email_to = 'test@test.com, customer@website.com';
} else {
    $email_to = 'blah@blah.com, customer@website.com';  
}

$email_subject = 'Contact Form Submission Bancroft Website';

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

// set error messages
$error_messages = array(
    'fullname' => 'Please enter a Name to proceed.',
    'email' => 'Please enter a valid Email Address to continue.',
    'comment' => 'Please enter your Message to continue.'
);

// 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 = 'New Website Comment: ' . "\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

        $email = explode(',', $email_to);

        foreach($email as $e) {
            $e = trim($e);
            mail($e, $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));
}
