(PHP) html 表单中不同值的不同值

Question

我有一个带有两个单选按钮的联系表。但我需要根据所选的单选按钮向客户端显示消息。 我会尝试更好地解释： 如果客户选择“是”单选按钮并按提交，则会出现一条消息“太棒了！我在那里看到你了！”我将收到一封包含所选选项的电子邮件。与“否”单选按钮相同，但它会显示“来吧...”消息。

这是我的 php：

<?php
if(isset($_POST['enviar'])) {
    $remetente = "[email protected]"; 
    $destinatario = "[email protected]";
    $assunto = "Subject";
    $data = date("d/m/y");
    $hora = date("H:i");
    $charset = $_POST['charset'];
    $nome = $_POST['nome'];
    $email = $_POST['email'];

    //This is the radio button value that i want to put conditionals.
    $rsvp = $_POST['rsvp'];
    $navegador = $_SERVER['HTTP_USER_AGENT'];
    $ip = $_SERVER['REMOTE_ADDR'];
    $corpo = utf8_decode("Data: ".$data."<br />Hora: ".$hora."<br />Nome: ".$nome."<br />E-mail: ".$email."<br />Ip: ".$ip."<br />Browser: ".$navegador."<br />RSVP: ".$rsvp."\r\n");

    $headers = "MIME-Version: 1.0\r\n";
    $headers .= "Content-type: text/html; charset=".$charset."\r\n";
    $headers .= "Reply-To: ".$remetente."\r\n";

    $headers .= "From: ".$remetente."\r\n";


    //This is the part that i think it has to be changed.
    if(mail($destinatario, $assunto, $corpo, $headers)) {
        echo '<meta http-equiv="refresh" content=0;url=message_sended.php/>';
    } else {
        echo '<meta http-equiv="refresh" content=0;url=error.php/>';
    }
} else {
    echo '<meta http-equiv="refresh" content=0;url=error.php/>';
}
?>

我已经尝试过这个，但不起作用：

    if(mail($destinatario, $assunto, $corpo, $headers) ) {
        if($rsvp = 'YES'){
            echo '<meta http-equiv="refresh" content=0;url=message_sended_YES.php/>';
        } else {
            echo '<meta http-equiv="refresh" content=0;url=error.php/>';
        }
    } else {
        echo '<meta http-equiv="refresh" content=0;url=error.php/>';
    }

    if($rsvp = 'NO'){
        echo '<meta http-equiv="refresh" content=0;url=message_sended.php_NO/>';
    } else {
        echo '<meta http-equiv="refresh" content=0;url=error.php/>';
    }
} else {
    echo '<meta http-equiv="refresh" content=0;url=error.php/>';
}

然后我这样做了：

if(mail($destinatario, $assunto, $corpo, $headers)) {
    if($rsvp == 'sim'){
        echo '<meta http-equiv="refresh" content=0;url=sim.php>';
    } 
    else
    {
        echo '<meta http-equiv="refresh" content=0;url=contato_mensagem_erro.php>';
    }
}   
else 
{
    echo '<meta http-equiv="refresh" content=0;url=contato_mensagem_erro.php>';
}

if($rsvp == 'nao'){
    echo '<meta http-equiv="refresh" content=0;url=nao.php>';
} 
else
{
    echo '<meta http-equiv="refresh" content=0;url=contato_mensagem_erro.php>';
}
}   
else 
{
echo '<meta http-equiv="refresh" content=0;url=contato_mensagem_erro.php>';
}

不起作用。实际上，当用户选择“否”单选按钮时，他会收到正确的消息，但是当他选择“是”单选按钮时，他会收到错误的消息（错误消息），但我正常收到表单电子邮件...

<强>编辑 好的！有用！ 这就是我的做法：

if(mail($destinatario, $assunto, $corpo, $headers)) {

if($rsvp == "sim"){

   echo 

     header('Location: sim.php/');

} 

else

{

   echo "<meta http-equiv='refresh' content=0;url=contato_mensagem_erro.php>";

}

}   

else 

{

   echo "<meta http-equiv='refresh' content=0;url=contato_mensagem_erro.php>";

}

if($rsvp == "nao"){

   echo header('Location: nao.php/');

} 

else

{

   echo "<meta http-equiv='refresh' content=0;url=contato_mensagem_erro.php>";

}

}   

else 

{

   echo "<meta http-equiv='refresh' content=0;url=contato_mensagem_erro.php>";

}

我真的不知道它的编码是否正确，但它正在工作......

这些行将导致意外结果：

if($rsvp = 'YES'){
if($rsvp = 'NO'){

此方法将简单地将 $rsvp 的值分别设置为“YES”和“NO”。要测试等效性，您应该使用比较运算符 ==：

if($rsvp == 'YES'){

和

if($rsvp == 'NO'){
