利用ajax和PHP实现简单的流程管理

时间：2021-05-25

本文实例为大家分享了ajax和PHP实现简单的流程管理，供大家参考，具体内容如下

首先要先有一个新建流程的页面xinjian.php

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>新建</title><script src="../FENGZHUANG/jquery-3.1.1.min.js"></script></head><body><h1>新建流程</h1><div>请选择节点人员：<select id="user"> <?php session_start();//需要将一些数据暂时存在session里 include("../FENGZHUANG/DBDA.class.php"); $db = new DBDA(); $sql = "select * from users"; $arr = $db->Query($sql); foreach($arr as $v) { echo "<option value='{$v[0]}'>{$v[2]}</option>"; } ?></select><input type="button" value="添加节点" id="add" /></div><br /><div> <?php if(!empty($_SESSION["user"])) { $attr = $_SESSION["user"]; foreach($attr as $k=>$v) //索引为$k,取值为$v { $sname = "select name from users where uid='{$v}'"; //取出名称 $name = $db->StrQuery($sname); echo "<div>{$k}--{$name}--<input type='button' value='删除' key='{$k}' class='del' /></div>"; //向处理页面传的是key的值 } } ?></div><br /><div>请输入流程名称：<input type="text" id="name" /></div><br /><input type="button" value="保存" id="btn" /></body><script type="text/javascript">//添加节点按钮加点击$("#add").click(function(){ var uid = $("#user").val(); $.ajax({ url:"chuli.php", data:{uid:uid,type:0}, //传入一个type参数，以确保在同一页面处理时与其它的分开处理 type:"POST", dataType:"TEXT", success: function(data){ window.location.href="xinjian.php" rel="external nofollow" rel="external nofollow" ; //刷新页面 } }); }) //给删除按钮加点击$(".del").click(function(){ var key = $(this).attr("key"); //取删除的是哪条数据 $.ajax({ url:"chuli.php", data:{key:key,type:1}, type:"POST", dataType:"TEXT", success:function(data){ window.location.href="xinjian.php" rel="external nofollow" rel="external nofollow" ; } }); })//给保存按钮加点击$("#btn").click(function(){ var name = $("#name").val(); //取输入框中输入内容的值 $.ajax({ url:"chuli.php", data:{name:name,type:2}, type:"POST", dataType:"TEXT", success:function(data){ alert("保存成功！"); } }); })</script></html>

处理页面chuli.php

<?phpsession_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; }

发起流程页面faqi.php

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>发起流程</title><br /><script src="../FENGZHUANG/jquery-3.1.1.min.js"></script></head><body><h1>发起流程</h1><div>请选择发起的流程： <select id="liucheng"> <?php session_start(); include("../FENGZHUANG/DBDA.class.php"); $db = new DBDA(); $sql = "select * from liucheng"; $arr = $db->Query($sql); foreach($arr as $v) { echo "<option value='{$v[0]}'>{$v[1]}</option>"; } ?> </select></div><br /><div>请输入内容： <textarea id="nr"></textarea></div><br /><input type="button" value="发起" id="btn" /></body><script type="text/javascript">$("#btn").click(function(){ var code = $("#liucheng").val(); var content = $("#nr").val(); $.ajax({ url:"chuli.php", data:{code:code,content:content,type:3}, type:"POST", dataType:"TEXT", success: function(data){ alert("发起成功！"); } }); })</script></html>

审核页面shenhe.php

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>审核</title></head><body><h1>审核页面</h1><table width="100%" border="1" cellpadding="0" cellspacing="0"> <tr> <td>流程代号</td> <td>发起者</td> <td>发起内容</td> <td>是否结束</td> <td>发起时间</td> <td>操作</td> </tr> <?php session_start(); include("../FENGZHUANG/DBDA.class.php"); $db = new DBDA(); $uid = $_SESSION["uid"]; echo $uid; //查找登录者参与的所有流程 $sql = "select * from userflow where code in(select code from flowpath where uids='{$uid}')"; $arr = $db->Query($sql); //显示 foreach($arr as $v) { //判断该流程走到登录者 $lcdh = $v[1]; //流程代号 $towhere = $v[6];//流程走到哪 $sql = "select orders from flowpath where code='{$lcdh}' and uids='{$uid}'"; $order = $db->StrQuery($sql);//该人员在流程中的次序 if($towhere>=$order) { $caozuo = ""; if($towhere==$order) { $caozuo="<a href='tongguo.php?code={$v[0]}'>通过</a>"; } else { $caozuo="<span style='background-color:green;color:white'>已通过</span>"; } echo "<tr> <td>{$v[1]}</td> <td>{$v[2]}</td> <td>{$v[3]}</td> <td>{$v[4]}</td> <td>{$v[5]}</td> <td>{$caozuo}</td> </tr>"; } } ?></table></body></html>

tongguo.php

<?phpsession_start();include("../FENGZHUANG/DBDA.class.php");$db = new DBDA();//流程往下走$code = $_GET["code"];$sql = "update userflow set towhere=towhere+1 where ids='{$code}'"; //使流程向下走$db->Query($sql,0);//判断流程是否结束$sql = "select * from userflow where ids='{$code}'";$arr = $db->Query($sql);$lcdh = $arr[0][1]; //流程代号$tw = $arr[0][6]; //流程走到哪$sql = "select count(*) from flowpath where code='{$lcdh}'";$count = $db->StrQuery($sql); //该流程节点人数if($tw>=$count){ $sql = "update userflow set isok=1 where ids='{$code}'"; //如果结束了流程，将isok项改为结束。 $db->Query($sql,0);}header("location:shenhe.php");
