Php Ajax POST不工作$\u POST

我正试图通过ajax向php文件提交一个联系人表单。我使用phpMailer发送表单结果。然而，该职位似乎没有发挥作用。提交时，不会执行成功或错误条件。当我注释掉POST变量时，ajax请求成功执行，电子邮件发送（变量为空）。这是代码

<form  method="post" class="form2" id="form2Id" name="form" action="">

            <div class="formtitle">Form<</div>

            <div class="input">
                <div class="inputtext">Your Name: </div>
                <div class="inputcontent">

                    <input id="nameId" type="text" name="name" />

                </div>
            </div>

            <div class="input">
                <div class="inputtext">Your Phone Number: </div>
                <div class="inputcontent">

                    <input id="phoneNumberId" type="text" name="phoneNumber" />

                </div>
            </div>

            <div class="input">
                <div class="inputtext">Your Email Address: </div>
                <div class="inputcontent">

                    <input id="emailAddressId" type="text" name="emailAddress"/>

任何帮助都将不胜感激。

给定html行

和此php代码

$nameId=$\u POST['nameId'

您最终将得到一个空的

$nameId

，因为发布的值位于

$\u POST['name']

中。其他变量也是如此。

如果我注释掉post变量

<form  method="post" class="form2" id="form2Id" name="form" action="">

            <div class="formtitle">Form<</div>

            <div class="input">
                <div class="inputtext">Your Name: </div>
                <div class="inputcontent">

                    <input id="nameId" type="text" name="name" />

                </div>
            </div>

            <div class="input">
                <div class="inputtext">Your Phone Number: </div>
                <div class="inputcontent">

                    <input id="phoneNumberId" type="text" name="phoneNumber" />

                </div>
            </div>

            <div class="input">
                <div class="inputtext">Your Email Address: </div>
                <div class="inputcontent">

                    <input id="emailAddressId" type="text" name="emailAddress"/>

只要我输入有效的电子邮件地址，电子邮件就会成功发送。否则，电子邮件根本不会发送。在这两种情况下，ajax都会返回成功的响应。我已经尝试了上面的建议，使用名称而不是ID，但它不起作用。

尝试打印（$\u POST）；在php中，查看变量get postin to page是什么，然后从中解析您的需求值，就像在ajax数据选项中使用Serialize数据一样，在连接到表单、通过ajax提交表单、在php中处理表单、发送响应并通过电子邮件发送其内容的过程中，出现了什么问题？请缩小你的问题范围。将其精简为一段最小的代码来重现问题。如果我对post VAR进行注释，请尽量缩小您的问题范围，
