php + ajax 实现的写入数据库操作简单示例

<input class="name" type="text" placeholder="请输入您的姓名" id="name">
<input class="tel" type="text" placeholder="请输入您的手机号码" id="tel">
<span class="button_tijiao" id="form_tijiao"><img src="images/page8/button.png"></span>

<script type="text/javascript">
 $('#form_tijiao').click(function () {
  var name =$('#name').val(),tel=$('#tel').val();
  if(name=='' && tel ==''){
   alert("请检查是否输入姓名和电话！！！")
  }

  $.ajax({
   type:'post',
   url:'http://www.netnic.com.cn/formapi/form_qishangh5.php',
   data:{name:name,tel:tel},
   
   success:function (data, status, xhr) {
    alert('提交成功！请等候工作人员联系！')
   },
   error:function (xhr, errorType, error) {

   }

  })
 })

</script>

<?php
ini_set('date.timezone','Asia/Shanghai');

$con = mysql_connect("localhost","admin","qishangxiangyunnetnic20160407");
if (!$con)
 {
 die('Could not connect: ' . mysql_error());
 }

mysql_select_db("qishang_form", $con);

$time = date('Y-m-d H:i:s',time());

$sql="INSERT INTO netnich5 (name, tel_number,posttime)
VALUES
('$_POST[name]','$_POST[tel]','$time')";

if (!mysql_query($sql,$con))
 {
 die('Error: ' . mysql_error());
 }
echo "1 record added";

?>

callback( {username: "", is_login: false} );
