Question

我的网站没有发送联系邮件，它显示错误<div class="alert_box error"><i class="fa fa-exclamation-triangle"></i><p>undefined!</p></div>，但即使JS设置为显示消息也没有。我的代码有错误吗？你能告诉我我错了什么吗？

HTML：

<form id="contact_form2" class="contact_form var2">
            <ul>
              <li>
                <input type="text" name="cf_name" placeholder="Nome">
              </li>
              <li>
                <input type="text" name="cf_subject" placeholder="Assunto">
              </li>
              <li>
                <textarea name="cf_message" placeholder="Mensagem"></textarea>
              </li>
            </ul>
            <button class="button type1"><span><span>Enviar</span><span>Enviar</span></span></button>
          </form>

PHP：

<?php 

$user_email = "marketing@fontlife.com.br";

$mail = array(
    "name" => htmlspecialchars($_POST['cf_name']),
    "email" => htmlspecialchars($_POST['cf_email']),
    "subject" => htmlspecialchars($_POST['cf_subject']),
    "message" => htmlspecialchars($_POST['cf_message'])
);

function validate($arr){

    return !empty($arr['name']) && strlen($arr['message']) > 20 && filter_var($arr['email'],FILTER_VALIDATE_EMAIL);

}

if(validate($mail)){

    echo mail($user_email, $mail['subject'], 
        "Name : {$mail['name']}\n" 
        ."E-mail : {$mail['email']}\n"
        ."Message : {$mail['message']}" 
    );

}


?>

JS：

($('#contact_form2').length){

        var cf = $('#contact_form2');
        cf.append('<div class="message_container2"></div>');

        cf.on("submit",function(event){

            var self = $(this),text;

            var request = $.ajax({
                url:"bat/mail.php",
                type : "post",
                data : self.serialize()
            });

            request.then(function(data){
                if(data == "1"){

                    text = "Sua mensagem foi enviada com sucesso!";

                    cf.find('input:not([type="submit"]),textarea').val('');

                    $('.message_container2').html('<div class="alert_box success"><i class="fa fa-smile-o"></i><p>'+text+'</p></div>')
                        .delay(150)
                        .slideDown(300)
                        .delay(4000)
                        .slideUp(300,function(){
                            $(this).html("");
                        });

                }
                else{
                    if(cf.find('textarea').val().length < 20){
                        text = "Sua mensagem deve conter no mínimo 20 caracteres!"
                    }
                    if(cf.find('input').val() == ""){
                        text = "Todos os campos devem ser preenchidos!";
                    }
                    $('.message_container2').html('<div class="alert_box error"><i class="fa fa-exclamation-triangle"></i><p>'+text+'</p></div>')
                        .delay(150)
                        .slideDown(300)
                        .delay(4000)
                        .slideUp(300,function(){
                            $(this).html("");
                        });
                }
            },function(){
                $('.message_container2').html('<div class="alert_box error"><i class="fa fa-exclamation-triangle"></i><p>Falha na conexão com o servidor!</p></div>')
                        .delay(150)
                        .slideDown(300)
                        .delay(4000)
                        .slideUp(300,function(){
                            $(this).html("");
                        });
            });

            event.preventDefault();
        });

    }

即page。

在条件之后，在打印错误消息之前验证text是否有值。

if(cf.find('textarea').val().length < 20){
    text = "Sua mensagem deve conter no mínimo 20 caracteres!"
}
if(cf.find('input').val() == ""){
    text = "Todos os campos devem ser preenchidos!";
}
if (text != undefined && text != ""){
    $('.message_container2').html('<div class="alert_box error"><i class="fa fa-exclamation-triangle"></i><p>'+text+'</p></div>')
        .delay(150)
        .slideDown(300)
        .delay(4000)
        .slideUp(300,function(){
            $(this).html("");
        });
}

我的mailphp有任何错误吗？
