PHP郵件導致錯誤：「header missing」

Question

我一直在使用PHP郵件表單一段時間，現在它不能在新網站上工作。

以下錯誤結果：

PHP Warning: mail() [function.mail]: "sendmail_from" not set in php.ini or custom "From:" header missing in E:\home\ -mypagefoldername- \Web\form.php on line 16

這是form.php的文件中的PHP代碼：

<? 
$mensagem = "Nome: ".$_POST['nome']." \n"; 
//email que o usuário preencheu 
$mensagem .= "Email: ".$_POST['email']." \n"; 
$mensagem .= "Assunto: ".$_POST['assunto']." \n"; 
$mensagem .= "Telefone: ".$_POST['fone']." \n"; 
$mensagem .= "Endereço: ". $_POST['mensagem']; 
$headers = ""; 
//email do seu domínio hospedado 
$emailsender = "email@mydomain.com"; 
//email de quem vai receber 
$emaildestinatario = "email@mydomain.com"; 
$assunto = "Mensagem do Parceiro Pipa"; 

// Envio dos dados do Formulário para seu e-mail: 
if(!mail($emaildestinatario, $assunto, $mensagem, $headers ,"-r".$emailsender)) 

{ 
// Se for Postfix - hospedagem linux 
$headers .= "Return-Path: " . $emailsender . $quebra_linha; 
} 
echo ' 
<script type="text/JavaScript"> 
alert("Email sent! Thank you!"); 
location.href="index.html" 
</script> 
'; 

?> 

很抱歉的葡萄牙語。

表單頁面是用下面的表單代碼一個簡單的HTML頁面：

<form method="post" action="form.php"> 

        <label>Nome</label> 
        <input name="nome" placeholder="Nome completo."> 

        <label>Telefone</label> 
        <input name="fone" placeholder="Número de telefone com DDD.">      

        <label>Assunto</label> 
        <input name="assunto" placeholder="Qual o motivo do seu contato?">      

        <label>Mensagem</label> 
        <textarea name="mensagem" placeholder="Escreva aqui sua mensagem."></textarea> 



        <label>Email</label> 
        <input name="email" type="email" placeholder="Email para contato."> 

        <input id="submit" name="submit" type="submit" value="Enviar"> 

</form> 

可能有人請幫助我嗎？ =/

感謝您的耐心等待！

Answer 1

如上所述，您可能會遺漏$headers變量中的From:聲明！

<?php 
    $From = "YourEmailAddress@example.com"; 
    $headers .= "From: Your Name <". $From .">\n"; 
?> 

到您的$headers字符串的頂部附近。雖然爲了將來的參考，你可能想看看PHPMailer Class，一個很好的&安全類，可以有效地處理PHP mail。

Answer 2

您沒有設置從頭，這是造成這個問題，正如下面的文檔中說明。

Note:

When sending mail, the mail must contain a From header. This can be set with the additional_headers parameter, or a default can be set in php.ini.

Failing to do this will result in an error message similar to Warning: mail(): "sendmail_from" not set in php.ini or custom "From:" header missing. The From header sets also Return-Path under Windows.

從http://php.net/manual/en/function.mail.php

在你的情況，你應該使用;

$headers = "From: webmaster@example.com" . "\r\n"; 

Answer 3

請php.ini文件更改以下設置

啓用電子郵件您應該取消註釋以下行或在該行

;sendmail_from = 

的開頭刪除分號並更改該設置爲這個例子（如果本地主機）

sendmail_from = localhost@localhost 

如果你在一個產品您必須根據您的域更改默認地址，因此administrator@domain.com
