如何使用PHP实现微信小程序的任务审批功能?
随着微信小程序的普及和发展,越来越多的企业和组织开始在小程序上构建自己的业务系统。其中,任务审批功能是一项常见的需求。本文将介绍如何使用PHP语言来实现微信小程序的任务审批功能,并提供具体的代码示例。
一、准备工作
在开始之前,我们需要先准备以下环境和资源:
二、数据库设计
在开始编写代码之前,我们需要先设计数据库表结构,来存储任务的信息和审批记录。
三、后端代码实现
连接数据库
<?php $servername = "localhost"; $username = "your_username"; $password = "your_password"; $dbname = "your_database"; $conn = new mysqli($servername, $username, $password, $dbname); if ($conn->connect_error) { die("连接失败: " . $conn->connect_error); } ?>
创建任务
<?php $task_name = $_POST['task_name']; $task_content = $_POST['task_content']; $creator_id = $_POST['creator_id']; $approver_id = $_POST['approver_id']; $sql = "INSERT INTO task (task_name, task_content, creator_id, approver_id, status, create_time) VALUES ('$task_name', '$task_content', '$creator_id', '$approver_id', 'pending', NOW())"; if ($conn->query($sql) === TRUE) { $result = array('code' => 200, 'message' => '任务创建成功'); } else { $result = array('code' => 500, 'message' => '任务创建失败'); } echo json_encode($result); ?>
查询任务列表
<?php $creator_id = $_GET['creator_id']; $sql = "SELECT * FROM task WHERE creator_id = '$creator_id'"; $result = $conn->query($sql); if ($result->num_rows > 0) { $tasks = array(); while($row = $result->fetch_assoc()) { $tasks[] = $row; } $result = array('code' => 200, 'message' => '查询成功', 'data' => $tasks); } else { $result = array('code' => 500, 'message' => '查询失败'); } echo json_encode($result); ?>
审批任务
<?php $history_id = $_POST['history_id']; $task_id = $_POST['task_id']; $approver_id = $_POST['approver_id']; $result = $_POST['result']; $sql = "INSERT INTO approval_history (history_id, task_id, approver_id, approval_time, result) VALUES ('$history_id', '$task_id', '$approver_id', NOW(), '$result')"; if ($conn->query($sql) === TRUE) { // 更新任务状态 $update_sql = "UPDATE task SET status = '$result' WHERE task_id = '$task_id'"; $conn->query($update_sql); $result = array('code' => 200, 'message' => '审批成功'); } else { $result = array('code' => 500, 'message' => '审批失败'); } echo json_encode($result); ?>
四、小程序端代码实现
创建任务页面(createTask)
Page({ data: { task_name: '', task_content: '', creator_id: '', approver_id: '', }, createTask: function() { wx.request({ url: 'https://your_domain.com/create_task.php', method: 'POST', data: { task_name: this.data.task_name, task_content: this.data.task_content, creator_id: this.data.creator_id, approver_id: this.data.approver_id, }, success: function(res) { console.log(res.data); if (res.data.code === 200) { wx.showToast({ title: '任务创建成功', }); } else { wx.showToast({ title: '任务创建失败', icon: 'none', }); } }, fail: function() { wx.showToast({ title: '请求失败', icon: 'none', }); }, }); }, });
查询任务列表页面(taskList)
Page({ data: { creator_id: '', tasks: [], }, onLoad: function() { var that = this; wx.request({ url: 'https://your_domain.com/query_task.php', data: { creator_id: this.data.creator_id, }, success: function(res) { console.log(res.data); if (res.data.code === 200) { that.setData({ tasks: res.data.data, }); } else { wx.showToast({ title: '查询失败', icon: 'none', }); } }, fail: function() { wx.showToast({ title: '请求失败', icon: 'none', }); }, }); }, });
审批任务页面(approveTask)
Page({ data: { history_id: '', task_id: '', approver_id: '', result: '', }, approveTask: function() { wx.request({ url: 'https://your_domain.com/approve_task.php', method: 'POST', data: { history_id: this.data.history_id, task_id: this.data.task_id, approver_id: this.data.approver_id, result: this.data.result, }, success: function(res) { console.log(res.data); if (res.data.code === 200) { wx.showToast({ title: '审批成功', }); } else { wx.showToast({ title: '审批失败', icon: 'none', }); } }, fail: function() { wx.showToast({ title: '请求失败', icon: 'none', }); }, }); }, });
以上是使用PHP实现微信小程序的任务审批功能的简单示例。当然,实际应用中还需要考虑更多的情况,比如数据验证、用户权限等。希望能对大家有所帮助。
