我有一个AJAX表单，我正在努力工作，我无法弄清楚为什么。我没有收到和PHP错误，因为我检查了日志文件。基本上，当我提交表格时，什么也没发生。我有另一种形式非常相似，它正在工作，所以我不知道发生了什么。我可能会忽略一些非常简单的事情。
以下是表格：
<div id="give-away-form">
<form method="post" action="ajax.php" class="form-horizontal">
<div class="form-group">
<div class="col-sm-2 hidden-xs"></div>
<label for="give_away_name" class="col-sm-2 col-xs-12 control-label">Name</label>
<div class="col-sm-5 col-xs-12">
<input type="text" class="form-control" name="give_away_name" id="give_away_name" placeholder="Name">
</div>
<div class="col-sm-3 hidden-xs"></div>
</div>
<div class="form-group">
<div class="col-sm-2 hidden-xs"></div>
<label for="give_away_email" class="col-sm-2 col-xs-12 control-label">Email</label>
<div class="col-sm-5 col-xs-12">
<input type="text" class="form-control" name="give_away_email" id="give_away_email" placeholder="Email">
</div>
<div class="col-sm-3 hidden-xs"></div>
</div>
<div class="form-group">
<div class="col-sm-2 hidden-xs"></div>
<label for="give_away_phone_no" class="col-sm-2 col-xs-12 control-label">Phone No</label>
<div class="col-sm-5 col-xs-12">
<input type="text" class="form-control" name="give_away_phone_no" id="give_away_phone_no" placeholder="Phone No">
</div>
<div class="col-sm-3 hidden-xs"></div>
</div>
<div class="form-group">
<!-- Street -->
<div class="col-sm-2 hidden-xs"></div>
<label for="give_away_street" class="col-sm-2 col-xs-12 control-label">Street</label>
<div class="col-sm-5 col-xs-12">
<input class="form-control" name="give_away_street" id="give_away_street" placeholder="Street">
</div>
<div class="col-sm-3 hidden-xs"></div>
</div>
<div class="form-group">
<!-- End Street -->
<!-- City -->
<div class="col-sm-2 hidden-xs"></div>
<label for="give_away_city" class="col-sm-2 col-xs-12 control-label">City</label>
<div class="col-sm-2 col-xs-12">
<input class="form-control" name="give_away_city" id="give_away_city" placeholder="City">
</div>
<!-- End City -->
<!-- State -->
<label for="give_away_state" class="col-sm-1 col-xs-12 control-label">State</label>
<div class="col-sm-2 col-xs-12">
<select class="form-control" name="give_away_state" id="give_away_state">
<option value="">State</option>
<option value="AL">Alabama</option>
<option value="AK">Alaska</option>
<option value="AZ">Arizona</option>
<option value="WA">Washington</option>
<option value="WV">West Virginia</option>
<option value="WI">Wisconsin</option>
<option value="WY">Wyoming</option>
</select>
</div>
<!-- <div class="col-sm-3 hidden-xs"></div> -->
</div>
<div class="form-group">
<div class="col-sm-2 hidden-xs"></div>
<label class="col-sm-2 col-xs-12 control-label hidden-xs"> </label>
<div class="col-sm-5 col-xs-12 text-left">
<input type="hidden" name="action" value="give_away_form" />
<input type="submit" class="btn btn-primary" value="Submit">
<div class="clear"></div>
<div id="give_away_form_message"></div>
</div>
<div class="col-sm-3 hidden-xs"></div>
</div>
</form>
<!-- End Form -->
</div>
这是PHP：
if(isset($_POST['action']) && $_POST['action'] == 'give_away_form') {
$result = array();
$give_away_name = strip_tags(trim($_POST['give_away_name']));
$give_away_email = strip_tags(trim($_POST['give_away_email']));
$give_away_phone_no = strip_tags(trim($_POST['give_away_phone_no']));
$give_away_street = strip_tags(trim($_POST['give_away_street']));
$give_away_city = strip_tags(trim($_POST['give_away_city']));
$give_away_state = strip_tags(trim($_POST['give_away_state']));
if($give_away_name == '')
$result['error']['give_away_name'] = 'Name required.';
if($give_away_email == '')
$result['error']['give_away_email'] = 'Email address required.';
else if(!filter_var($give_away_email, FILTER_VALIDATE_EMAIL))
$result['error']['give_away_email'] = 'Invalid email address.';
if($give_away_phone_no == '')
$result['error']['give_away_phone_no'] = 'Phone no required.';
if($give_away_comment == '')
$result['error']['give_away_comment'] = 'Comment required.';
if(!isset($result['error'])) {
$to = $give_away_to;
$subject = $give_away_subject;
$message = '<p>Hi,</p>';
$message .= '<p>You have received this message from give_away form on Hope Starts Here - Columbus</p>';
$message .= '<p><strong>Name:</strong>'.$give_away_name.'</p>';
$message .= '<p><strong>Email:</strong>'.$give_away_email.'</p>';
$message .= '<p><strong>Phone No:</strong>'.$give_away_phone_no.'</p>';
$message .= '<p><strong>Comment:</strong><br>'.$give_away_comment.'</p>';
$message .= '<p> </p>';
$message .= '<p><strong>Thank You.</strong></p>';
$headers = "From: " . strip_tags($give_away_from) . "\r\n";
$headers .= "Reply-To: ". strip_tags($give_away_email) . "\r\n";
//$headers .= "CC: abc@example.com\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
if(@mail($to, $subject, $message, $headers)) {
$result['success'] = 'Thank you for entering to win! Once the names are drawn, we will contact the winners by email or phone.';
} else {
$result['error']['give_away_form_message'] = 'Something wrong please try again...';
}
}
echo json_encode($result);
die;
}
而且，JS：
$('#give-away-form form').submit(function(e) {
$('span.form-message').remove();
e.preventDefault();
$this = $(this);
var url = $this.attr('action');
var data = $this.serialize();
$.ajax({
url: url,
method: 'POST',
data: data,
dataType: 'json',
success: function(response) {
if(response.error) {
var focus_field = '';
$.each(response.error, function(id, message) {
$('#'+id).after('<span class="form-message label label-danger">' + message + '</span>');
if(focus_field == '')
focus_field = id;
});
$('#'+focus_field).focus();
}
if(response.success) {
$('#give_away_form_message').after('<span class="form-message label label-success">' + response.success + '</span>');
$this[0].reset();
}
}
});
});

您可以尝试使用此代码告诉我们哪些警报有效吗？
$('#give-away-form form').submit(function(e) {
$('span.form-message').remove();
e.preventDefault();
$this = $(this);
var url = $this.attr('action');
var data = $this.serialize();
$.ajax({
url : url,
method : 'POST',
data : data,
dataType : 'json',
success : function(response) {
alert("Number 1");
if(response.error) {
alert("Number 2");
var focus_field = '';
$.each(response.error, function(id, message) {
alert("Number 3");
$('#'+id).after('<span class="form-message label label-danger">' + message + '</span>');
if(focus_field == '')
focus_field = id;
});
$('#'+focus_field).focus();
}
if(response.success) {
alert("Number 4");
$('#give_away_form_message').after('<span class="form-message label label-success">' + response.success + '</span>');
$this[0].reset();
}
}
});
});

您可以在PHP代码之前添加echo "page works";，然后尝试在没有ajax的情况下在浏览器中访问它。只需转到服务器上的ajax.php，查看该页面是否可访问并与我们分享结果。

我发现了问题。我从另一种形式复制了这个表格，忘了改变几个变量。
if($give_away_comment == '')
$result['error']['give_away_comment'] = 'Comment required.';
没有$give_away_comment。
感谢所有人的帮助！
