Php 联系人表单中存在未定义的错误

我最近也用php创建了一个联系人表单，但每次单击submit，我只会得到一个未定义的错误，其他什么都没有。谁能告诉我我错过了什么

HTML

<form id="main-contact-form" class="contact-form" name="contact-form"       method="post" action="contactengine.php">
    <div class="col-sm-5 col-sm-offset-1">
        <div class="form-group">
            <label>Name *</label>
            <input type="text" name="Name" class="form-control" required="required">
        </div>
        <div class="form-group">
            <label>Email *</label>
            <input type="email" name="Email" class="form-control" required="required">
        </div>
        <div class="form-group">
            <label>Phone *</label>
            <input type="number" name="Phone" class="form-control">
        </div>
        <div class="form-group">
            <label>Company Name</label>
            <input type="text" class="form-control">
        </div>
    </div>
    <div class="col-sm-5">
        <div class="form-group">
            <label>Subject *</label>
            <input type="text" name="subject" class="form-control" required="required">
        </div>
        <div class="form-group">
            <label>Message *</label>
            <textarea name="message" id="Message" required="required" class="form-control" rows="8"></textarea>
        </div>
        <div class="form-group">
            <button type="submit" name="submit" class="btn btn-primary btn-lg" required="required">Submit Message</button>
        </div>
    </div>
</form>

我只在html上发现了一个未定义的错误，其他什么都没有

在你的帖子中有一些区分大小写的问题，我更正了它并在相应的行中发表了评论。 检查一下

Post您得到的错误

f（$success）

应该是

if（$success）

。您已经注释掉了设置

$success

的代码。请将此行更改为$success=mail（$EmailTo，$Subject，$Body，“From:”）//发送电子邮件我认为问题中存在复制错误。现在我在上一行的

if

中看到了

I

。我猜

$success=

这一行在评论后面。如果需要帮助，请准确复制代码。请参阅@bub尝试填写此页面，我仍然没有定义
