我正在尝试使用PHP和jQuery Validate.min.js（http://jqueryvalidation.org/）创建PHP联系表单
我试图为jQuery和PHP提取我需要的所有代码，但由于某种原因，它的返回值就在它的顶部。
请参阅下面的代码：
<?php
$hasError = false;
$sent = false;
if(issent($_POST['submitform'])){
$name = trim(htmlspecialchars($_POST['name'], ENT_QUOTES));
$email = trim($_POST['email']);
$message = trim(htmlspecialchars($_POST['message'], ENT_QUOTES));
$fieldsArray = array(
'name' => $name,
'email' => $email,
'message' => $message
);
$errorArray = array();
foreach($fieldsArray as $key => $val){
switch ($key){
case 'name':
case 'message':
if(empty($val)){
$hasError = true;
$errorArray[$key] = ucfirst($key) = " field was left empty.";
}
break;
case 'email':
if(!filter_var($email, FILTER_VALIDATE_EMAIL)){
$hasError = true;
$errorArray[$key] = "Invalid Email Address entered";
}else{
$email = filter_var($email, FILTER_SANITIZE_EMAIL);
}
break;
}
}
if($hasError !== true){
$to = "samuelnico.norton@gmail.com";
$subject = "Message from Contact Form";
$msgcontents = "Name: $name<br/> Email : $email<br/> Message: $message";
$headers = "MIME-Version: 1.0 \r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1 \r\n";
$headers .= "From: $name <$email> \r\n";
$mailsent = mail($to, $subject, $msgcontents, $headers);
if($mailsent){
$sent = true;
unset($name);
unset($email);
unset($message);
}
}
}
?>

正如您所看到的，我在html文件的顶部删除了代码。现在我想在每个文本框下面显示错误。
你可以看到它是如何进行的：http://snowboardflowbindings.com/testing/testfile.php
致命错误：第25行的/home/olymnews/public_html/snowboardflowbindings.com/testing/testfile.php中的写入上下文中不能使用函数返回值
答案 0 :(得分：0)
从你的php中的issent()到jQuery中缺少()和:之类的东西，各种各样的错误...尝试将代码分解为更易于管理的部分和尝试保持尽可能多的逻辑，你可以从视图中分离出来：
<?php
function validate_input($var = false,$opt = false)
{
$var = trim($var, ENT_QUOTES);
return ($opt != 'email')? htmlspecialchars($var) : filter_var($var, FILTER_VALIDATE_EMAIL);
}
function error_codes($code = false)
{
$valid['name'] = "Enter your name";
$valid['subject'] = "Write a subject";
$valid['email'] = "Invalid email";
$valid['message'] = "Write your comments";
return (isset($valid[$code]))? $valid[$code] : false;
}
function send_email($settings = false)
{
$to = (!empty($settings['to']))? $settings['to']:false;
$from = (!empty($settings['from']))? "From:".$settings['from'].PHP_EOL:"no-replay@test.com";
$subject = (!empty($settings['subject']))? $settings['subject']:"This is a great subject";
$message = (!empty($settings['message']))? $settings['message']:false;
$headers = (!empty($settings['headers']))? $settings['headers']:false;
if(in_array(false, $settings) === true)
return false;
return (mail($to,$subject,$message,$headers));
}
// ISSET not ISSENT
if(isset($_POST['submitform'])){
$payload['name'] = validate_input($_POST['name']);
$payload['email'] = validate_input($_POST['email'],'email');
$payload['message'] = validate_input($_POST['message']);
print_r($payload);
print_r($_POST);
if(in_array(false,$payload) === true) {
foreach($payload as $key => $err)
$errors[$key] = error_codes($key);
}
if(empty($errors)){
$to = "samuelnico.norton@gmail.com";
$subject = "Message from Contact Form";
$msgcontents = "Name: ".$payload['name']."<br/> Email : ".$payload['email']."<br/> Message: ".$payload['message'];
$headers = "MIME-Version: 1.0 \r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1 \r\n";
$headers .= "From: ".$payload['name']." <".$payload['email']."> \r\n";
$success = (send_email(array("to"=>$to,"subject"=>$subject,"message"=>$msgcontents, "headers"=>$headers)));
}
}
print_r($errors);
