当我上传后在服务器端渲染时，我收到一封电子邮件，但它是空白的。From是空的，文本是空的，ECHO中$name is的部分是空的。你知道我该怎么做吗?
这是我的表格:
<form action="survey.php" method="post" name="survey">
<table>`enter code here`
<tr><th colspan="2">Survey</th></tr>
<tr><td>Name:</td><td align="center"><input type="text"
name="name" id="name" /></td></tr>
<tr><td>When was your last visit</td><td
align="center"><select id="long" name="long">
<option value="Select">Please Select</option>
<option value="1-2 days">1-2 days ago</option>
<option value="3-5 days">3-5 days ago</option>
<option value="1-2 weeks">1-2 weeks ago</option>
<option value="3-5 weeks">3-5 weeks ago</option>
<option value="2 months">2 months</option>
<option value="3+months">3+ months </option>
<option value="Never">Never Visited</option>
</select></td></tr>
<tr>
<td>Tell us about your experience?</td><td
align="center"><textarea cols="22" rows="5" id="experience"
name="experience"></textarea></td></tr>
<tr><td>Will you come back
to visit again?</td><td align="center"><input type="checkbox"
id="visit" name="visit" value="Yes" />Yes<input type="checkbox"
id="visit" name="visit" value="No" />No</td></tr>
<tr><td colspan="2"><input type="submit" value="Submit" /><input
type="reset" value="Reset" /></td></tr>
</table>
</form>
和PHP代码

From为空，因为您写了$headers = "From: $name'r'n";和$name没有在任何地方声明。修改为$headers = "From: $nameField'r'n";
对于$long(应该是$selectField)， $experience(应该是$commentsField)和$visit(应该是$visitField)的引用也是如此。
对于echo "$theResults";:
- 为什么要把HTML存储在字符串中然后回显出来?退出PHP模式，直接输出HTML。
- 为什么用引号包围变量
$theResults?echo $theResults;更好，添加引号首先在内存中创建一个新的字符串，然后返回它。
您正在返回未声明的字段…尝试将extract($_POST);添加到代码的开头
如何设置错误报告?它是打印还是进入日志?回显phpinfo()查看。你的日志会告诉你很多。
在下一行中，我注意到在"mail"answers"("之间有一个空格。不能有空格
$success = mail ($webMaster， $emailSubject， $body， $headers);
如果你正在查看你的错误日志，你会发现像这样的东西很容易错过
