核心逻辑:流程管理,在各种系统中扮演很重要的地位,可以把设定好的流程放入系统中,规定好几个节点,只要所有节点都通过,就可以通过。
建立四张数据库表:
1.我们首先做一个新建流程页面 flow.php,先把节点做好
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> <script src="bootstrap/js/jquery-1.11.2.min.js"></script> </head> <body> <h2>管理员新建流程</h2> <p><select id="users" name="users"> <? "./DBDA.class.php" = = "select * from users" = ->query(,0( "<option value='{[0]}'>{[2]}</option>"?> </select> <input type="button" value="添加" id="add" /> </p> <br /> <p> <?((["jd" "还未添加节点人员!" = ["jd"]; ( =>){ = "select name from users where uid='{}'" = ->StrQuery(,0); "<p>{}--{}--<input type='button' value='删除' class='del' code='{}' /></p>"?> </p> <br /> <p><input type="text" id="name" /> </p> <br /> <input type="button" value="新建" id="addbtn" /> </body> <script> "#add").click( uid = $("#users")..:"flowchuli.php",:"POST",:{uid:uid,type:0},:"TEXT",:.location.href = "flow.php"".del").click( k = $(this).attr("code"); $.:"flowchuli.php",:"POST",:{k:k,type:1},:"TEXT",:.location.href = "flow.php" $("#addbtn").click( name = $("#name")..:"flowchuli.php",:"POST",:{name:name,type:2},:"TEXT",:"添加成功!"</script> </html>
2.做新建流程页面的处理页面flowchuli.php
<?phpsession_start();require_once "./DBDA.class.php";$db = new DBDA();$type = $_POST["type"];switch($type){ case 0: $uid = $_POST["uid"]; if(empty($_SESSION["jd"])){//暂存节点 $arr = array($uid);//新造数组 $_SESSION["jd"] = $arr;//存入session }else{ $arr = $_SESSION["jd"];//取数组 $arr[] = $uid;//追加变量到数组 $_SESSION["jd"] = $arr; } break; case 1: $k = $_POST["k"]; $arr = $_SESSION["jd"]; unset($arr[$k]); $arr = array_values($arr);//重新对数组进行排序,有返回值接收 $_SESSION["jd"] = $arr; break; case 2: $name = $_POST["name"]; $code = time();//自动生成 $sql = "insert into flow values('{$code}','{$name}')";//流程表 $db->query($sql); //流程节点表 $arr = $_SESSION["jd"]; foreach($arr as $k=>$v){ $sql = "insert into flowpath values(0,'{$code}','{$v}',{$k})"; $db->query($sql); } break; }
效果如图:
点击选择节点人员可以从数据库调所有人员名单,现在把李四,马七和张三放入流程中,做一个请假流程:
注意:Code必须用varchar,不能用time,因为在上面用了时间戳
3.现在我们在做一个登陆用户页面flowlogin.php,提交请假流程的所有步骤:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> <script src="bootstrap/js/jquery-1.11.2.min.js"></script> <script src="bootstrap/js/bootstrap.min.js"></script> <link href="bootstrap/css/bootstrap.min.css" rel="stylesheet" type="text/css"/> </head> <style> .-left:-top:.-left:-top: -.name,.-width:.-top:</style> <body> <form ="form-horizontal" role="form"> <h3 ="title">用户登录</h3> <p ="quanju"> <p ="form-group yangshi1"> <label ="firstname" ="col-sm-2 control-label">用户名:</label> <p ="col-sm-10"> <input type="text" ="form-control name" id="uid" placeholder="请输入用户名"> </p> </p> <p ="form-group yangshi2"> <label ="lastname" ="col-sm-2 control-label">密码:</label> <p ="col-sm-10"> <input type="text" ="form-control pwd" id="pwd" placeholder="请输入密码"> </p> </p> <p ="form-group"> <p ="col-sm-offset-2 col-sm-10"> <p ="checkbox"> <label> <input type="checkbox"></label> <label> <input type="checkbox"></label> </p> </p> </p> <p ="form-group"> <p ="col-sm-offset-2 col-sm-10"> <button type="button" id="login" ="btn btn-warning" value="登录" ></button> </p> </p> </p> </form> </body> <script> "#login").click( uid = $("#uid"). pwd = $("#pwd")..:"post",:"flowloginchuli.php",:{uid:uid,pwd:pwd},:"TEXT",:(data.()=="OK".location.href="flowmain.php""用户名或密码有误!"</script> </html>
4.登录后跳转的主页面flowmain.php
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> </head> <body> <h2>主页面</h2> <a href="flowfq.php">发起流程</a> <a href="flowsh.php">审核流程</a> </body> </html>
5.发起流程页面flow.php
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> <script src="bootstrap/js/jquery-1.11.2.min.js"></script> </head> <body> <h2>发起流程</h2> <form action="flowfqchuli.php" method="post"> 请选择流程: <select name="flow"> <?php require_once "./DBDA.class.php"; $db = new DBDA(); $sql = "select * from flow"; $arr = $db->query($sql,0); foreach($arr as $v){ echo "<option value='{$v[0]}'>{$v[1]}</option>"; } ?> </select> <br /> <br /> 请输入内容: <textarea name="content"></textarea> <br /> <br /> <input type="submit" value="确定" /> </form> </body> </html>
6.做发起流程的处理页面flowfq.php
<?phpsession_start();require_once "./DBDA.class.php";$db = new DBDA(); $code = $_POST["flow"]; $uid = $_SESSION["uid"];$content = $_POST["content"]; $time = date("Y-m-d H:i:s"); $sql = "insert into userflow values(0,'{$code}','{$uid}','{$content}',0,'{$time}',0)";$db->query($sql);header("location:flowmain.php");
7.审核页面flowsh.php
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> <script src="bootstrap/js/jquery-1.11.2.min.js"></script> <script src="bootstrap/js/bootstrap.min.js"></script> <link href="bootstrap/css/bootstrap.min.css" rel="stylesheet" type="text/css"/> </head> <body> <p><h2>审核页面</h2> <table class="table table-bordered"> <thead> <tr> <th>流程代号</th> <th>发起人</th> <th>发起内容</th> <th>通过状态</th> <th>发起时间</th> <th>操作</th> </tr> </thead> <tbody> <?php session_start(); $uid = $_SESSION["uid"]; require_once "./DBDA.class.php"; $db = new DBDA(); //相关子查询(用到父查询的数据)(父查询卡在某一位置) $sql = "select * from userflow a where towhere>=(select b.order from flowpath b where b.code=a.code and b.uid='{$uid}')"; $arr = $db->query($sql,0); foreach($arr as $v){ //$v[6];//流程走到的位置towhere //$v[1];//利用代号和session中存的name查询order $sql = "select order from flowpath where code='{$v[1]}' and uid='{$uid}'"; $order = $db->StrQuery($sql,0);//该人员在流程中的次序 $str = ""; if($v[6]==$order){ //传主键值 $str = "<a href='flowtgchuli.php?ids={$v[0]}'>通过</a>"; }else{ $str = "<span style='color:green'>已通过</span>"; } echo "<tr> <th>{$v[1]}</th> <th>{$v[2]}</th> <th>{$v[3]}</th> <th>{$v[4]}</th> <th>{$v[5]}</th> <th>{$str}</th> </tr>"; } ?> </tbody> </table> </p> </body> </html>
8.做审核页面的处理页面flowshchuli.php
<?php session_start(); $uid = $_SESSION["uid"];require_once "./DBDA.class.php"; $db = new DBDA();$ids = $_GET["ids"]; $sql = "update userflow set towhere=towhere+1 where ids='{$ids}'"; $db->query($sql);//判断;流程是否结束(使用相关子查询) $swc = "update userflow a set isok=1 where ids='{$ids}' towhere>=(select count(*) from flowpath b where b.code=a.code)";header("location:flowsh.php");
流程效果如图:
李四的页面:
点击通过后:
数据库:towhere变成1后结束流程
接着该马七:
然后是张三:
数据库:isok变成1后结束流程
