Question

所以我得到了这段代码：

<?php
// ----------------------------------------- 
//  The Web Help .com
// ----------------------------------------- 
// remember to replace your@email.com with your own email address lower in this code.

// load the variables form address bar
$name = $_REQUEST["name"];
$message = $_REQUEST["message"];
$from = $_REQUEST["from"];
$verif_box = $_REQUEST["verif_box"];

// remove the backslashes that normally appears when entering " or '
$name = stripslashes($name); 
$message = stripslashes($message); 
$from = stripslashes($from); 

// check to see if verificaton code was correct
if(md5($verif_box).'a4xn' == $_COOKIE['tntcon']){
    // if verification code was correct send the message and show this page
    $message = "Name: ".$name."\n".$message;
    $message = "From: ".$from."\n".$message;
    mail("myMail@gmail.com", 'MSG from site', $_SERVER['REMOTE_ADDR']."\n\n".$message, "From: $from");
    // delete the cookie so it cannot sent again by refreshing this page
    setcookie('tntcon','');
} else {
    // if verification code was incorrect then return to contact page and show error
    header("Location:".$_SERVER['HTTP_REFERER']."?&from=$from&message=$message&wrong_code=true");
    exit;
}
?>

我想做的是：

点击此表单的提交按钮后，我想留在同一页面
正确发送邮件后，我希望按钮更改＆＃34;发送＆＃34;到＆＃34; MSG发送＆＃34; （也许可以将按钮颜色更改为绿色）

我该怎么做这些事情？

任何链接到源的机会我都可以学习如何编写代码吗？谢谢！

Answer 1

要在提交后保持同一页面，只需在表单标记中填写action=""，或者您可以完全停止操作。
要更改按钮文字，您可以使用javascript document.getElementById("buttonId").value= "MSG";

Answer 2

您可以使用jQuery执行此操作。以下是一个起点。

var dataString = $("#contactform").serialize();

$.ajax({
     type: "POST",
     url: "../public/txtmailer-v3.php",
     data: dataString,
     cache: false,
        success: function(html){
        //insert html and css edits here
       }, error: function(html){
           alert("Error sending email!");
       }
     }
});
