为什么我的PHP脚本发送空白电子邮件？

当我上传后在服务器端渲染它时，我收到一封电子邮件，但它是空白的。来自空白的文本是空白ECHO中的$名称是空白的部分。任何想法我能做些什么来完成这项工作？为什么我的PHP脚本发送空白电子邮件？

这里是我的形式：

<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>

*请*您可以更改标题的问题：“我需要我的代码帮助”不是一个问题。。 –

$ name变量不应该是$ nameField吗？如果不是$ name从哪里来的？而其他变量也是如此 –

然后把你的代码集中到t他的问题。不是整个文件。你会得到更好的帮助。 –
