处理页面chuli.php
<?php session_start(); include("../FENGZHUANG/DBDA.class.php"); $db = new DBDA(); $type = $_POST["type"]; switch($type) { case 0://添加节点的加载数据,向session数组中添加数据 $uid = $_POST["uid"]; if(empty($_SESSION["user"])) { $arr = array($uid); $_SESSION["user"] = $arr; } else { $arr = $_SESSION["user"]; array_push($arr,$uid); $_SESSION["user"] = $arr; } break; case 1://取节点的索引，然后删除，重新索引 $key = $_POST["key"]; $arr = $_SESSION["user"]; unset($arr[$key]); //删除 $arr = array_values($arr); //重新索引 $_SESSION["user"] = $arr; break; case 2: $name = $_POST["name"]; $code = time(); //添加流程 $sql = "insert into liucheng values('{$code}','{$name}')"; $db->Query($sql,0); //添加流程节点 $arr = $_SESSION["user"]; foreach($arr as $k=>$v) { $sql = "insert into flowpath values('','{$code}','{$v}','{$k}')"; $db->Query($sql,0); } break; case 3: //用户发起流程 $code = $_POST["code"]; $nr = $_POST["content"]; $uid = $_SESSION["uid"]; $time = date("Y-m-d H:i:s"); $sql = "insert into userflow values('','{$code}','{$uid}','{$nr}',0,'{$time}',0)"; $db->Query($sql,0); break; }
