将通过AJAX数据到MySQL数据库 [英] Insert data through ajax into mysql database

问题描述

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();

?>

不过，我想通过AJAX来插入我的电子邮件数据库。我不希望我的网页重定向，BCZ每次页面刷新得到的空值得到插入到数据库的时间。

But i want to insert my email to database through ajax. I dont want my page to get redirected, bcz every time the page got refreshed, the null value got inserted to the database..

我只是想让我的电子邮件得到插入到通过AJAX的数据库，与放大器;之后，该电子邮件信箱 即。

I just want my email got inserted to database through ajax, & after that the email box i.e.

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

应该得到消失和放大器;应该有一行你已经成功订阅..

should get disappeared & there should be the line "you ve been successfully subscribed" ..

任何短暂code会是非常有用的..感谢ü提前：）

Any brief code ll be very useful.. thank u in advance :)

推荐答案

试试这个：

  $(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);
         }
});
 });

和 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的_ 这是pcated德$ P $。

Don't use mysql_ it's deprecated.

另一种方法：

其实，如果你的问题是插入到数据库中null值，则尝试这一点，在这里没有必要阿贾克斯。

Actually if your problem is null value inserted into the database then try this and here no need of 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>
