邮件未发送到收件人电子邮件。请解释以下代码有什么问题导致它无法发送。

邮件表格(html)

    <h1>Send Us Your Feedback!</h1>
<form action="send_mail.php" method="post">
<table>
<tr>
<td>Email Adress:</td>
<td>
<input type="text" name="email_from" value="" maxlength="100" />
</td>
</tr>
<tr>
<td>Artist id:</td>
<td>
<textarea rows="10" cols="50" name="artist_id"></textarea>
</td>
</tr>
<tr><td>&nbsp;</td>
<td>
<input type="submit" value="Submit" />
</td>
</tr>
</table>
</form>


发送邮件(php)

这将作为未定义的索引出现。您不需要将其包装在 $_REQUEST 中。

$message = $_REQUEST['Advertiser email: $email_from \n Artist id: $artist_id '] ;

在您设置电子邮件来源和艺术家 ID 后移动它，并将其设为字符串。 

$message = "Advertiser email: $email_from \n Artist id: $artist_id" ;

改成mail($webmaster_email,"FEEDBACK FOR AN ARTIST",$message,"FROM:".$email_from);
