通过ajax将数据插入mysql数据库

通讯：

<form id="form-search" method="post" action="<?php echo $_SERVER['PHP_SELF'];?>">
    <span><span class="style2">Enter you email here</span>:</span>
    <input name="email" type="email" id="email" required/>

 <input type="submit" value="subscribe" class="submit" onclick="return fun()" />
                        </form>
                        <?php
mysql_connect("localhost","","");
mysql_select_db("");
error_reporting(E_ALL && ~E_NOTICE);

$email=$_POST['email'];
$sql="INSERT INTO newsletter_email(email) VALUES ('$email')";
$result=mysql_query($sql);
if($result){
echo "You have been successfully subscribed.";
}
 if(!$sql)
die(mysql_error());

mysql_close();

?>

但我想通过 Ajax 将我的电子邮件插入数据库。我不希望我的页面被重定向，因为每次刷新页面时，空值都会插入到数据库中。

我只是希望我的电子邮件通过 Ajax 插入到数据库中，然后是电子邮箱 IE。

<input name="email" type="email" id="email" required/>  
<input type="submit" value="subscribe" class="submit" onclick="return fun()" />

应该会消失，并且应该有一行“您已成功订阅”..

任何简短的代码都会非常有用..提前谢谢你:)

尝试这个：

  $(document).on('click','#save',function(e) {
  var data = $("#form-search").serialize();
  $.ajax({
         data: data,
         type: "post",
         url: "insertmail.php",
         success: function(data){
              alert("Data Save: " + data);
         }
});
 });

and in insertmail.php:

<?php 
if(isset($_REQUEST))
{
        mysql_connect("localhost","root","");
mysql_select_db("eciticket_db");
error_reporting(E_ALL && ~E_NOTICE);

$email=$_POST['email'];
$sql="INSERT INTO newsletter_email(email) VALUES ('$email')";
$result=mysql_query($sql);
if($result){
echo "You have been successfully subscribed.";
}
}
?>

不要使用mysql_它已被弃用。

another method:

实际上，如果您的问题是插入数据库中的空值，那么尝试这个，这里不需要ajax。

<?php
if($_POST['email']!="")
{
    mysql_connect("localhost","root","");
    mysql_select_db("eciticket_db");
    error_reporting(E_ALL && ~E_NOTICE);
    $email=$_POST['email'];
    $sql="INSERT INTO newsletter_email(email) VALUES ('$email')";
    $result=mysql_query($sql);
    if($result){
    //echo "You have been successfully subscribed.";
              setcookie("msg","You have been successfully subscribed.",time()+5,"/");
              header("location:yourphppage.php");
    }
     if(!$sql)
    die(mysql_error());
    mysql_close();
}
?>
    <?php if(isset($_COOKIE['msg'])){?>
       <span><?php echo $_COOKIE['msg'];setcookie("msg","",time()-5,"/");?></span> 
    <?php }?>
<form id="form-search" method="post" action="<?php echo $_SERVER['PHP_SELF'];?>">
    <span><span class="style2">Enter you email here</span>:</span>
    <input name="email" type="email" id="email" required/>
    <input type="submit" value="subscribe" class="submit"/>
</form>
