1：连接数据库：

$conn = mysql_connect("localhost","root","www.xunjobs.com") or die("数据库连接失败".mysql_error());
mysql_select_db("db_pursey",$conn) or die("数据库访问失败".mysql_error());
mysql_query("set names gb2312");
?>

2：插入数据：

include("conn/conn.php");
$type=$_POST[type];
$title=$_POST[title];
$content=$_POST[content];
$linkman=$_POST[linkman];
$tel=$_POST[tel];
//$edate=date("Y-m-d h:i:s");获得系统日期
$edate=date("Y-m-d H:i:s");
$sql=mysql_query("insert into tb_info(type,title,content,linkman,tel,checkstate,edate) values('$type','$title','$content','$linkman','$tel',0,'$edate')");
if($sql){
//php中输出<script>语句的方法</script>
echo "<script>alert('恭喜您，信息发布成功！');window.location.href='release.php';</script>";
}else{
echo "<script>alert('对不起，信息发布失败！');history.back();</script>";
}
?>

3：查询数据

    include("conn/conn.php");
    $type=$_POST[type];
    $content=$_POST[content];
    $sql1=mysql_query("select * from tb_leaguerinfo where checkstate=1 and type='$type' and (content like'%$content%' or title like'%$content%' or linkman like'%$content%' or tel like'%$content%')");
    $info1=mysql_fetch_array($sql1);
    $sql=mysql_query("select * from tb_info where checkstate=1 and type='$type' and (content like'%$content%' or title like'%$content%' or linkman like'%$content%' or tel like'%$content%')");
    $info=mysql_fetch_array($sql);
    ?>
   
    if($info1){
    do{
      ?>
                 

                   
                     
                   
                   
                     
                   
                   
                     
                   
                   
                     
                   
                 

『".$content."",$info1[type]);?>』 ".$content."",$info1[title]);?>  ".$content."",$info1[edate]);?>

    ".$content."",$info1[content]);?>

 联系人：".$content."",$info1[linkman]);?>   联系电话：".$content."",$info1[tel]);?>

               
    }while($info1=mysql_fetch_array($sql1));
    ?>
   
           
           
             

   
     if($info){
     do{
    ?>

    ".$content."",$info[content]);?>

 联系人：".$content."",$info[linkman]);?>   联系电话：".$content."",$info[tel]);?>

                 
     } while($info=mysql_fetch_array($sql));
     }
    }else{
    ?>
   
     if($info){
     do{
    ?>
