发信息页面如图:

5.发布信息完成后要进入处理页面了,也就是提交到的infochuli.php,最后返回发送信息界面
<?php
session_start();
$uid = $_SESSION["uid"];
$recever = $_POST["recever"];
$content = $_POST["content"];
$arr = $_POST["recever"];
$t = date("Y-m-d H:i:s");
require_once "./DBDA.class.php";
$db = new DBDA();
$sql = "insert into liuyan values('','{$uid}','{$t}','{$recever}','{$content}',0)";
$arr = $db->query($sql);
if($arr && !empty($arr)){
header("location:publish_info.php");
}else{
echo "发送失败!";
}
?>
