This article mainly introduces the php+ajax initiation process and review process (taking leave as an example). Friends who need it can refer to it
The previous essay has mentioned how to create a new process, so now Let’s take a look at how to initiate a process and review process~~~
Let’s talk about the idea first:
(1) Log in with session Obtain the user's id
(2) The user initiates a process
Note: You need to write the application reason
(3) The reviewer at the node will review it in sequence
Three tables:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> </head> <body> <form method="post" action="denglu-cl.php"> 用户名:<input type="text" name="uid" /><br /> 密码:<input type="password" name="pwd" /><br /> <input type="submit" value="登录" /> </form> </body> </html>
<?php session_start(); require "../DB.class.php"; $db = new DB(); $uid = $_POST["uid"]; $pwd = $_POST["pwd"]; $sql = "select pwd from users where uid='{$uid}'"; $mm = $db->strquery($sql); if($pwd==$mm && !empty($pwd)) { $_SESSION["uid"]=$uid; header("location:liucheng.php"); } else { echo "密码或登录名输入错误"; } ?>
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> <style> #body{ height: 200px; width: 300px; background-color: gainsboro; margin: 200px auto; text-align: center; vertical-align: middle; line-height: 30px; } </style> </head> <body> <p id="body"> <h2>主页面</h2> <p> <a href="faqi.php" rel="external nofollow" >发起流程</a><br /> <a href='shenhe.php'>审核流程</a> </p> </p> </body> </html>
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> <style> #body{ height: 250px; width: 300px; background-color: gainsboro; margin: 200px auto; text-align: left; vertical-align: middle; line-height: 30px; padding-left: 30px; } </style> </head> <body> <p id="body"> <form method="post" action="faqi-cl.php"> <h2>发起流程页面</h2> <select id="lc"> <?php require "../DB.class.php"; $db = new DB(); $sql = "select * from liucheng"; $arr = $db->query($sql); foreach($arr as $v) { echo "<option value='{$v[0]}'>{$v[1]}</option>"; } ?> </select><br /> 发起流程事由: <textarea class="nr"> </textarea><br /> <input type="button" value="确定发起" /> </form> </p> </body> </html>
<?php session_start(); require "../DB.class.php"; $db = new DB(); $code = $_POST["lc"]; $nr =$_POST["nr"]; $uid = $_SESSION["uid"]; $time = date("Y-m-d H:i:s",time()); $sql = "insert into liuchengpath values ('','{$code}','{$uid}','{$nr}',0,'{$time}',0)"; $db->query($sql,0); header("location:liucheng.php"); ?>
##Step 5: Process review page shenhe.php
Knowledge points used: subquery: irrelevant subquery (subquery and parent query can be executed independently); related subquery (the conditions in the subquery use something from the parent query )
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> <style> #body{ height: 450px; width: 800px; background-color: gainsboro; margin: 200px auto; text-align: left; vertical-align: middle; line-height: 30px; padding-left: 30px; } </style> </head> <body> <p id="body"> <h2>流程审核页面</h2> <?php session_start(); $uid = $_SESSION["uid"]; require "../DB.class.php"; $db = new DB(); //先取该用户参与的所有流程 //并且取流程步骤到达该用户或已经被改用户审核通过的记录 $sql="select * from liuchengpath a where code in(select code from liuchengjiedian where uids='{$uid}') and towhere >=(select orders from liuchengjiedian b where b.code = a.code and b.uids = '{$uid}')"; $arr = $db->query($sql); //var_dump($arr); echo "<table border='1' width='100%' cellpadding='0' cellspacing='0'> <tr> <td>流程代号</td> <td>发起者</td> <td>发起内容</td> <td>发起时间</td> <td>是否结束</td> <td>操作</td> </tr>"; foreach($arr as $v){ //操作最后一列 //设置默认项 $zt = "<a href='tongguo-cl.php?code={$v[0]}'>审核未通过</a>"; $sql = "select orders from liuchengjiedian where code ='{$v[1]}' and uids ='{$uid}'"; $wz = $db->strquery($sql); if($v[6]>$wz) { $zt = "<span style='color:green'>审核已通过</span>"; } echo "<tr> <td>{$v[1]}</td> <td>{$v[2]}</td> <td>{$v[3]}</td> <td>{$v[4]}</td> <td>{$v[5]}</td> <td>{$zt}</td> </tr>"; } echo "</table>"; ?> </p> </body> </html>
Sixth Step: Write tongguo-cl.php page (important)
<?php $ids = $_GET["code"]; require "../DB.class.php"; $db = new DB(); //点击审核后,towhere列加1,目的是使流程向下走 $sql = "update liuchengpath set towhere = towhere+1 where ids ='{$ids}' "; $db->query($sql,0); //当流程走到最后一个审核的人时,流程要结束 //获取该流程最大的orders $sql =" select max(orders) from liuchengjiedian where code = (select code from liuchengpath where ids ='{$ids}')"; $maxorders = $db->strquery($sql); //获取该用户处于哪个位置,也就是towhere等于多少 $sql ="select towhere from liuchengpath where ids ='{$ids}'"; $towhere = $db->strquery($sql); //判断是否已到达最后一个审核的人 if($towhere>$maxorders) { $sql = "update liuchengpath set isok=1 where ids='{$ids}'"; // var_dump($sql); $db->query($sql,0); } header("location:shenhe.php"); ?>
After writing this step, click "Audit failed" and it will change to "Audit passed";
Let’s verify the effect from the beginning:
First: initiate a new leave process:
Second: zhangsan Is the first person to be reviewed
Click "After review failed",
Finally: zhaoliu is the last reviewer
##After clicking "Audit failed", whether the end is changed to 1; The operation changes to green "Audit passed"~~~

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
