php处理ajax页面

保存页

<?php
include("config.php");
date_default_timezone_set('Asia/Shanghai');
$dat=date("Y-m-d H:i:s");
$str=$_GET['val'];
$iss=$_GET['iss'];
$sqls="insert into records (issueid,num,year) values ('$iss','$str','$dat') ";
$results=$mysqli->query($sqls);
$sql1="select * from records ";
$result1=$mysqli->query($sql1);
$sql="select  a.num,count(*) as ci from (select  id,num from records order by id desc LIMIT 0, 100) as a group by a.num";
$result=$mysqli->query($sql);
if($result1->num_rows){
while($field=$result->fetch_object()){
echo "<div class='issues'>数字：".$field->num;
echo "，出现次数：".$field->ci;
echo "</div>";
}
}else{echo "没有数据";
}$mysqli->close();?>

刷新页，列表

<?php$sql1="select  *  from records";
$result1=$mysqli->query($sql1);
$sql="select * from (select  id,issueid,num  from records order by id desc LIMIT 0, 100) as b order by b.id";
$result=$mysqli->query($sql);
if($result1->num_rows){
while($field=$result->fetch_object()){echo "<div class='list1'>";echo "第".$field->issueid."期，";echo " 数字：".$field->num;echo "</div>";
}
}else{echo "没有数据";
}$mysqli->close();?>

刷新页，统计

<?php$sql1="select  *  from records";
$result1=$mysqli->query($sql1);
$sql="select  a.num,count(*) as ci from (select  id,num from records order by id desc LIMIT 0, 100) as a group by a.num";
$result=$mysqli->query($sql);
if($result1->num_rows){
while($field=$result->fetch_object()){echo "<div class='issues'>数字：".$field->num;echo "，出现次数：".$field->ci;echo "</div>";
}
}else{echo "没有数据";
}$mysqli->close();?>

删除页

<?php$sql1="select  *  from records";
$result1=$mysqli->query($sql1);
if($result1->num_rows){$sql="delete from records where id in (select * from (SELECT max(id)as id FROM records)d)";$result=$mysqli->query($sql);echo "删除成功!请刷新列表";
}else{echo "没有数据";
}
$mysqli->close();?>

连接数据页

<?php
$mysqli=new mysqli("localhost","sa","","issue");
if($mysqli->connect_error){die('连接失败'.$mysqli->connect_error);
}
?>

到这里就可以了。

以下预览图,当100期时。

输入101期保存时候如图;
