Question

当我在上传后在服务器端呈现它时，我收到一封电子邮件，但它是空白的。 From为空白，文本为空白，ECHO中$ name的部分为空白。我有什么想法可以做到这一点吗？

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>

我的PHP代码

Answer 1

From为空白，因为您已写入$headers = "From: $name\r\n";并且$name未在任何地方声明。将其更改为$headers = "From: $nameField\r\n";。

对于$long（应为$selectField），$experience（应为$commentsField）和$visit（应为{ {1}}）。

至于$visitField：

为什么还要将HTML存储在字符串中然后将其回显？退出PHP模式并开始直接输出HTML。
为什么将变量echo "$theResults";括在引号中？ $theResults更好，添加引号首先在内存中创建一个 new 字符串，然后回显它。

Answer 2

您正在回复未声明的字段...尝试将extract($_POST);添加到代码的开头

Answer 3

您的错误报告设置如何？它打印还是记录？回声phpinfo（）看。你的日志会告诉你很多。

在下面的一行中，我注意到“mail”和“（”之间有一个空格。应该没有空格。

$ success = mail（$ webMaster，$ emailSubject，$ body，$ headers）;

如果你正在观察你的错误日志，你会发现很容易错过的事情。

为什么我的PHP脚本发送空白电子邮件？
