Question

这是我的 contact-form-handler.php 文件。单击提交按钮后，我想在PHP中发出警报。我成功接收邮件并重定向到我的主页但没有警报消息。如何在PHP中使用警告框？

我的表格工作正常，但这次我坚持这个简单的任务。

<?php 
    if(isset($_POST['submit'])){
        //$companyMail = 'enesh@gmail.com';
        $to = "eneshpal@gmail.com"; // this is your Email address
        $customerMail = $_POST['formEmail']; // this is the sender's Email address
        $first_name = $_POST['formFirstName'];
        $last_name = $_POST['formLastName'];
        $phone = $_POST['formPhone'];
        $text = $_POST['formText'];
        /* foreach($_POST['project_type'] as $project_type_value){} */
        $projectType = implode(', ',$_POST['project_type']);
        $scopeProject = implode(', ',$_POST['scope_project']);
        $project_type_Str = 'Project Type : '.$projectType;
        $scope_project_Str = 'Scope of Project : '.$scopeProject;
        $subject = "Form Submission";
        $message = "Hi, \n\n";
        $message .= "First Name: ".$first_name . "\nLast Name: " . $last_name . " \nEmail: " . $customerMail . " \nPhone : " . $phone . "\nDescription: " . $text . "\n";
        $message .=  $project_type_Str."\n";
        $message .= $scope_project_Str;
        //$message2 = "Here is a copy of your message " . $first_name . "\n\n" . $_POST['message'];
        //$headers = "From:" . $companyMail;
        //$headers2 = "From:" . $to;
        if(mail($to,$subject,$message)){
            //echo 'Mail Sent';
            //$message = "Thanks, We Will Contact you Shortly";
            //echo "<script type='text/javascript'>alert('$message');</script>";
            echo "<script>alert('Thanks, We Will Contact you Shortly');</script>";
            header('Location:get_estimation.php');
        }else{
            echo 'Mail Not Sent';
        }
        //mail($from,$subject2,$message2,$headers2); // sends a copy of the message to the sender
        /*if( "Mail Sent. Thank you " . $first_name . ", we will contact you shortly.")
        else die; */
        // You can also use header('Location: thank_you.php'); to redirect to another page.
    }
?>

Answer 1

您的脚本存在许多问题，但要回答您的关键问题...您echo正在使用alert()的javascript代码，这将阻止您的php {{ 1}}执行，因为在header('Location:get_estimation.php');被调用之前已经有输出发送到浏览器。 See here for more info

请记住，在发送任何实际输出之前，必须通过普通HTML标记，文件中的空行或PHP来调用header（）。使用include或require，函数或其他文件访问函数读取代码是一个非常常见的错误，并且在调用header（）之前输出空格或空行。使用单个PHP / HTML文件时存在同样的问题。

根据你上面的评论......

是的，先生，我只是希望在提交表单后呈现成功消息？

为您举例说明如何实现您所需要的......

header

要解释一下，您不应该使用从php渲染的浏览器原生javascript <?php if (!empty($_GET['success'])) { echo 'Thanks, we will contact you shortly'; exit; } if (isset($_POST['submit'])) { $to = "eneshpal@gmail.com"; $customerMail = $_POST['formEmail']; $first_name = $_POST['formFirstName']; $last_name = $_POST['formLastName']; $phone = $_POST['formPhone']; $text = $_POST['formText']; $projectType = implode(', ', $_POST['project_type']); $scopeProject = implode(', ', $_POST['scope_project']); $project_type_Str = 'Project Type : ' . $projectType; $scope_project_Str = 'Scope of Project : ' . $scopeProject; $subject = "Form Submission"; $message = "Hi, \n\n"; $message .= "First Name: " . $first_name . "\nLast Name: " . $last_name . " \nEmail: " . $customerMail . " \nPhone : " . $phone . "\nDescription: " . $text . "\n"; $message .= $project_type_Str . "\n"; $message .= $scope_project_Str; if (mail($to, $subject, $message)) { header('Location: get_estimation.php?success=1'); exit; } else { echo 'Mail Not Sent'; exit; } }来弹出并通知用户表单提交成功，特别是在重定向后立即。这只是一个糟糕的用户体验，它劫持浏览器窗口，直到他们点击确定，你无法真正设置本机警报窗口等。

相反，您应该在邮件成功发送后重定向成功alert变量（返回原始页面，假设在我的示例中为GET - 但您可以将其他地方重定向到另一个脚本）。然后，您可以在重定向到的脚本中检测此变量的存在，并显示相应的消息等。

Answer 2

在您的情况下，最好重定向用户

header('Location:get_estimation.php?success=true');

并传递GET参数。

当设置GET参数时，它将在你的get_estimation.php页面上显示你想要的内容

Answer 3

echo "Thank You,will contact you soon";
echo "<script>setTimeout(\"location.href = 'get_estimation.php';\",3000); </script>";
