PHP 函数成功与否的消息对话框

Question

我有一个 PHP 函数可以在将数据插入数据库之前检查一些数据。现在，无论我在哪里调用函数，我的 php 函数中都会显示这些消息。例如：div。我想要一个显示消息的消息框，而不是 div 中的小消息。我怎样才能做到这一点？谢谢

if($u_l_name == $dbuser_last_name and $u_name == $dbuser_first_name)
            {
                echo "Record Exists Already";
            }
            else
            {
                $stmt2 = $this->link->prepare("INSERT INTO employers (user_password, user_first_name, user_last_name, user_DOB, user_address, user_email, user_phone, user_gender, user_position, user_contract_type, user_contract_hours) VALUES (?,?,?,?,?,?,?,?,?,?,?)");
                $stmt2->bind_param("ssssssssssi", $u_password, $u_name, $u_l_name, $u_DOB, $u_address, $u_email, $u_phone, $u_gender, $u_position, $u_contract_type, $u_contract_hours);
                $stmt2->execute();
                $stmt2->close();
                echo "Record Added Succesfully";
            }

函数调用：

<?php
    if(isset($_POST['submitButton']))
        {    
         $admin_query->addEmployerData($u_password, $u_name, $u_l_name, $u_DOB, $u_address, $u_email, $u_phone, $u_gender, $u_position, $u_contract_type, $u_contract_hours);

        }
    ?>

你是指Javascriptalert方法吗？如果是的话，你可以这样做：

$message;
if($u_l_name == $dbuser_last_name and $u_name == $dbuser_first_name)
            {
                $message = "Record Exists Already";
            }
            else
            {
                $stmt2 = $this->link->prepare("INSERT INTO employers (user_password, user_first_name, user_last_name, user_DOB, user_address, user_email, user_phone, user_gender, user_position, user_contract_type, user_contract_hours) VALUES (?,?,?,?,?,?,?,?,?,?,?)");
                $stmt2->bind_param("ssssssssssi", $u_password, $u_name, $u_l_name, $u_DOB, $u_address, $u_email, $u_phone, $u_gender, $u_position, $u_contract_type, $u_contract_hours);
                $stmt2->execute();
                $stmt2->close();
                $message = "Record Added Succesfully";
            } 
            echo "<script>alert('$message')</script>";
