标签: php forms email contact-form

我正在处理一个带有下拉菜单的联系表格,以便为特定医生选择一个电子邮件地址。我正在使用模板,我没有太多的PHP经验。当我将表单上传到服务器时,我收到“警告:array_key_exists()的参数计数错误”,我无法查明问题。

<link href="css/contactform.css" rel="stylesheet" type="text/css" />
<?php

// Set email variables
$email_to = array('phys1' => 'phys1@xxxxxx.xxx', 'phys2' => 'phys2@xxxxxx.xxx');
if(array_key_exists($_POST['dropdown']))
{
$recipient = $emails[$_POST['dropdown']];
//send email to $recipient
}

$email_subject = 'Form submission';

// 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));
}

如果查看array_key_exists的文档,您会注意到该函数包含两个参数。键(数组键)和数组(要搜索有问题的数组键/索引的数组)。

您的代码:

if(array_key_exists($_POST['dropdown']))

是个问题。你可能意味着:

if(array_key_exists($_POST['dropdown'], $emails))

答案 1 :(得分:0)

尝试将array_key_exists替换为isset并查看是否适用于您

if(isset($_POST['dropdown']))
{
    $recipient = $emails[$_POST['dropdown']];
    //send email to $recipient
}
