我发现下面的代码处理一个接触的形式，并希望错误处理和异常添加到他们。
HTML表单的外观：
<div class="contact-form">
<form id="contact-form" action="sendmail.php" method="post" title="Contact Form" role="form">
<div class="col-sm-6">
<div class="form-group">
<label for="contact-name">Name</label>
<input type="text" name="name" placeholder="Enter your name..." class="contact-name" id="contact-name">
</div>
<div class="form-group">
<label for="contact-email">Email</label>
<input type="text" name="email" placeholder="Enter your email..." class="contact-email" id="contact-email">
</div>
<div class="form-group">
<label for="contact-subject bold">Subject</label>
<input type="text" name="subject" placeholder="Your subject..." class="contact-subject" id="contact-subject">
</div>
</div>
<div class="col-sm-6">
<div class="form-group">
<label for="contact-message">Message</label>
<textarea name="message" placeholder="Your message..." class="contact-message" id="contact-message"></textarea>
</div>
</div>
<div class="col-sm-12 text-center">
<button type="submit" class="btn btn-default sketchFlowPrint" id="submit">Send</button>
</div>
</form>
</div>
sendmail.php的样子：
<?php
// Email address verification
function isEmail($email) {
return(preg_match("/^[-_.[:alnum:]]+@((([[:alnum:]]|[[:alnum:]][[:alnum:]-]*[[:alnum:]])\.)+(ad|ae|aero|af|ag|ai|al|am|an|ao|aq|ar|arpa|as|at|au|aw|az|ba|bb|bd|be|bf|bg|bh|bi|biz|bj|bm|bn|bo|br|bs|bt|bv|bw|by|bz|ca|cc|cd|cf|cg|ch|ci|ck|cl|cm|cn|co|com|coop|cr|cs|cu|cv|cx|cy|cz|de|dj|dk|dm|do|dz|ec|edu|ee|eg|eh|er|es|et|eu|fi|fj|fk|fm|fo|fr|ga|gb|gd|ge|gf|gh|gi|gl|gm|gn|gov|gp|gq|gr|gs|gt|gu|gw|gy|hk|hm|hn|hr|ht|hu|id|ie|il|in|info|int|io|iq|ir|is|it|jm|jo|jp|ke|kg|kh|ki|km|kn|kp|kr|kw|ky|kz|la|lb|lc|li|lk|lr|ls|lt|lu|lv|ly|ma|mc|md|mg|mh|mil|mk|ml|mm|mn|mo|mp|mq|mr|ms|mt|mu|museum|mv|mw|mx|my|mz|na|name|nc|ne|net|nf|ng|ni|nl|no|np|nr|nt|nu|nz|om|org|pa|pe|pf|pg|ph|pk|pl|pm|pn|pr|pro|ps|pt|pw|py|qa|re|ro|ru|rw|sa|sb|sc|sd|se|sg|sh|si|sj|sk|sl|sm|sn|so|sr|st|su|sv|sy|sz|tc|td|tf|tg|th|tj|tk|tm|tn|to|tp|tr|tt|tv|tw|tz|ua|ug|uk|um|us|uy|uz|va|vc|ve|vg|vi|vn|vu|wf|ws|ye|yt|yu|za|zm|zw)$|(([0-9][0-9]?|[0-1][0-9][0-9]|[2][0-4][0-9]|[2][5][0-5])\.){3}([0-9][0-9]?|[0-1][0-9][0-9]|[2][0-4][0-9]|[2][5][0-5]))$/i", $email));
}
if($_POST) {
// Enter the email where you want to receive the message
$emailTo = '[email protected]';
$clientName = addslashes(trim($_POST['name']));
$clientEmail = addslashes(trim($_POST['email']));
$subject = addslashes(trim($_POST['subject']));
$message = addslashes(trim($_POST['message']));
$array = array();
$array['nameMessage'] = '';
$array['emailMessage'] = '';
$array['messageMessage'] = '';
if($clientName == '') {
$array['nameMessage'] = 'Please enter your name.';
}
if(!isEmail($clientEmail)) {
$array['emailMessage'] = 'Please insert a valid email address.';
}
if($message == '') {
$array['messageMessage'] = 'Please enter your message.';
}
if($clientName != '' && isEmail($clientEmail) && $message != '') {
// Send email
$headers = "From: " . $clientName . " <" . $clientEmail . ">" . "\r\n" . "Reply-To: " . $clientEmail . "\r\n";
mail($emailTo, $subject . ' (Example - Website)', $message, $headers);
}
echo json_encode($array);
} else {
header ('location: index.html#contact');
}
?>
jQuery脚本的样子：
// Contact form
$('.contact-form form').submit(function(e) {
e.preventDefault();
var form = $(this);
var nameLabel = form.find('label[for="contact-name"]');
var emailLabel = form.find('label[for="contact-email"]');
var messageLabel = form.find('label[for="contact-message"]');
nameLabel.html('Name');
emailLabel.html('Email');
messageLabel.html('Message');
var postdata = form.serialize();
$.ajax({
type: 'POST',
url: 'sendmail.php',
data: postdata,
dataType: 'json',
success: function(json) {
if(json.nameMessage !== '') {
nameLabel.append(' - <span class="red error-label"> ' + json.nameMessage + '</span>');
}
if(json.emailMessage !== '') {
emailLabel.append(' - <span class="red error-label"> ' + json.emailMessage + '</span>');
}
if(json.messageMessage !== '') {
messageLabel.append(' - <span class="red error-label"> ' + json.messageMessage + '</span>');
}
if(json.nameMessage === '' && json.emailMessage === '' && json.messageMessage === '') {
form.fadeOut('fast', function() {
form.parent('.contact-form').append('<h2 class="text-center"><span class="orange">Thanks for contacting us!</span> We will get back to you very soon.</h2>');
});
}
}
});
});
代码工作非常好的节选了两件事情：
我想例外添加到这一点。我想，如果有什么问题，除了当用户没有填写所有必填字段（如果用户没有在必填字段的形式必须显示填补了别的“请这个“别人”的功能我加入到只执行输入你的名字。”或‘请根据这是不填充字段）输入字段的顶部插入一个有效的电子邮件地址。’或‘请输入您的信息。’希望这是有道理的。
在你的PHP，你应该定义另一对夫妇的变量
1. $my_email = "[email protected]"; //senders email
2. $subject = "Query from My Domain"; //a subject line
然后用
mail($_REQUEST['email'],$subject,$message,$headers,"-f{$my_email}");
哪里
$headers = "From: " . $my_email;
其实我通常使用
$headers = "From: " . $my_email;
$headers .= PHP_EOL;
$headers .= "MIME-Version: 1.0".PHP_EOL;
$headers .= "Content-Type: multipart/mixed;".PHP_EOL;
$headers .= " boundary=\"boundary_sdfsfsdfs345345sfsgs\"";
我不太为什么你有接收器的在PHP电子邮件;这些值应该从形式发布
例如$field_order_keys = array('name','email','comment');
然后使用$_REQUEST要求
这将解决发件人的电子邮件问题
我已经建立了我接触PHP脚本的通用形式，我通常使用的plunker。它有胡言乱语和现场检查等在里面。也许你会发现它很有用（该链接不上降落，这是它上面的contactconfirm.php）
