前言
table 是 layui 中使用频率非常高的一个组件,用于在表格中对数据进行一系列动态化的操作,涵盖了日常业务所涉及的大部分需求。
一、HTML容器
<div class="layui-row">
<form class="layui-form layui-col-md12 x-so">
<div class="demoTable">
<div class="layui-input-inline">
<select name="major_name" id="major_name" lay-filter="major_name" lay-verify="required" lay-search></select>
</div>
<div class="layui-input-inline">
<select name="sub_name" id="sub_name" lay-filter="sub_name" lay-verify="required" lay-search></select>
</div>
<div class="layui-input-inline"><input type="text" class="layui-input" placeholder="姓名" id="user_name" autocomplete="off"></div>
<div class="layui-input-inline"><input type="text" class="layui-input" placeholder="学号" id="user_ticket" autocomplete="off"></div>
<div class="layui-input-inline">
<select name="user_verify" lay-filter="user_verify" id="user_verify">
<option value="">报名状态</option>
<option value="0">未报名</option>
<option value="1">已报名</option>
<option value="2">已审核</option>
</select>
</div>
<div class="layui-input-inline">
<select name="user_pay" lay-filter="user_pay" id="user_pay">
<option value="">缴费状态</option>
<option value="0">未缴费</option>
<option value="1">已缴费</option>
</select>
</div>
<a class="layui-btn layui-btn-normal" data-type="reload">查询</a>
{if $smarty.cookies.admin_menu eq "1"}
<a class="layui-btn" onclick="x_admin_show('导入用户信息','?m=User&a=userImport','','')"><i class="layui-icon layui-icon-form"></i>导入用户信息</a>
<a class="layui-btn layui-btn-danger" onclick="x_admin_show('导入缴费信息','?m=User&a=userPayImport','','')"><i class="layui-icon layui-icon-form"></i>导入缴费信息</a>
<a class="layui-btn layui-btn-normal" onclick="x_admin_show('导入考试信息','?m=User&a=userExamImport','','')"><i class="layui-icon layui-icon-form"></i>导入考试信息</a>
{/if}
<span class="x-right" style="line-height:40px"></span>
</div>
</form>
</div>
- 表格容器
<table class="layui-hide" id="lockTabel" lay-filter="lockTabel"></table>
二、php后端API数据
1.核心代码
public function getUser()
{
global $CONF_TABLE, $db, $res;
dbc();
@$user_work = get_param("user_work");
@$user_class = get_param("user_class");
@$user_name = get_param("user_name");
@$user_ticket = get_param("user_ticket");
@$user_verify = get_param("user_verify");
@$user_pay = get_param("user_pay");
@$p = get_param('page') == "" ? 1 : get_param('page');
@$pagesize = get_param('limit') == "" ? 15 : get_param('limit');
@$limit = ($p - 1) * $pagesize;
//按学院权限设置筛选条件;
if ($_COOKIE['admin_menu'] == 1) {//超级管理员
$filter_condition = " 1";
} elseif ($_COOKIE['admin_menu'] == 0) {//学院管理员
$filter_condition = " user_work = '" . $_COOKIE['admin_depart'] . "'";
} else {//禁止查询
$filter_condition = " 1 = 2";
}
/*用户分表 By Poleung 2023-02-26*/
$current_table = "user_" . $CONF_TABLE['current_table'];
$sql = "select user_id,user_ticket,user_name,user_gender,user_nation,user_card,user_phone,user_work,user_class,user_photo,user_verify,user_pay,user_sms,user_cet FROM " . $db->table($current_table) . " WHERE " . $filter_condition;
if ($user_ticket != "") {
$sql .= " AND user_ticket like '%" . $user_ticket . "%'";
}
if ($user_name != "") {
$sql .= " AND user_name like '%" . $user_name . "%'";
}
if ($user_work != "") {
$sql .= " AND user_work like '%" . $user_work . "%'";
}
if ($user_class != "") {
$sql .= " AND user_class like '%" . $user_class . "%'";
}
if ($user_verify != "") {
$sql .= " AND user_verify = " . $user_verify;
}
if ($user_pay != "") {
$sql .= " AND user_pay = " . $user_pay;
}
$sql .= " ORDER BY user_verify DESC,user_id DESC LIMIT " . $limit . "," . $pagesize;
$row = $db->queryall($sql);
//获取总记录;
$sql_c = "select user_id FROM " . $db->table($current_table) . " WHERE " . $filter_condition;
if ($user_ticket != "") {
$sql_c .= " AND user_ticket like '%" . $user_ticket . "%'";
}
if ($user_name != "") {
$sql_c .= " AND user_name like '%" . $user_name . "%'";
}
if ($user_work != "") {
$sql_c .= " AND user_work like '%" . $user_work . "%'";
}
if ($user_class != "") {
$sql_c .= " AND user_class like '%" . $user_class . "%'";
}
if ($user_verify != "") {
$sql_c .= " AND user_verify = " . $user_verify;
}
if ($user_pay != "") {
$sql_c .= " AND user_pay = " . $user_pay;
}
$sql_c .= " ORDER BY user_verify DESC,user_id DESC";
$row_c = $db->queryall($sql_c);
/*信息输出*/
$res['code'] = 0;
$res['msg'] = 0;
$res['count'] = count($row_c);
$res["data"] = $row;
die(json_encode_lockdata($res));
}
2.参数过滤
由于前端传递参数使用get方式,便于筛选和查询,但是也存在着SQL注入漏洞,因此使用get_param()
函数对参数进行安全过滤,具体封装参数不做展示,根据自己系统需要增加即可。
@$user_work = get_param("user_work");
@$user_class = get_param("user_class");
@$user_name = get_param("user_name");
@$user_ticket = get_param("user_ticket");
@$user_verify = get_param("user_verify");
@$user_pay = get_param("user_pay");
@$p = get_param('page') == "" ? 1 : get_param('page');
@$pagesize = get_param('limit') == "" ? 15 : get_param('limit');
3.权限判断
后台角色权限分为超级管理员和学院管理员,为了展示对应的数据,做好限设置筛选条件。
//按学院权限设置筛选条件;
if ($_COOKIE['admin_menu'] == 1) {//超级管理员
$filter_condition = " 1";
} elseif ($_COOKIE['admin_menu'] == 0) {//学院管理员
$filter_condition = " user_work = '" . $_COOKIE['admin_depart'] . "'";
} else {//禁止查询
$filter_condition = " 1 = 2";
}
4.获取总记录
在使用table模块翻页时,需要传递总页码,因此在后端开发时,单独增加一个数据记录的SQL查询语句。
$res['count'] = count($row_c);
三、table模块渲染
1.加载layui
layui.use(['table', 'layer', 'form'], function () {
var $ = layui.jquery,form = layui.form,table = layui.table;
//核心代码
});
2.筛选条件select表单加载
为了便于后台筛选操作,在layui中异步调用函数,快速下拉查询;同时设置<select name="major_name" id="major_name" lay-filter="major_name" lay-verify="required" lay-search></select>
lay-search属性,支持下拉和输入查询。
//获取学院;
getBigCategory();
getSubCategory('', '');
form.on("select(major_name)", function () {
var major_id = $("#major_name").val().split(',')[0];
//console.log(major_id);
getSubCategory(major_id,'');
});
3.表格渲染
核心代码
//表格渲染;
table.render({
elem: '#lockTabel'
, url: './api/api.php?act=getUser&token=3cab7ce4142608c0f40c785b5ab5ca24'
, layout: ['count', 'prev', 'page', 'next', 'limit', 'skip']
, limits: [15,30, 50, 100, 200, 500, 1000]
, limit: 15
, toolbar: '#toolbarDemo'
,defaultToolbar: ['filter','exports', 'print']
, even: true
, page: true
, id: 'searchTable'
, cols: [[
{type: 'checkbox',width: 100}
, {field: 'user_photo', title: '证件照', align: 'center', templet: function (d) {
if(d.user_photo == null || d.user_photo == ""){
return '<img src="upload/nopic.png" alt="" width="50" height="70">';
}else{
return '<img src="'+d.user_photo+'" alt="" width="50" height="70">';
}
}
}
, {field: 'user_ticket', title: '学号', sort: true}
, {field: 'user_name', title: '姓名', sort: true}
, {field: 'user_work', title: '学院', sort: true}
, {field: 'user_class', title: '班级', sort: true}
, {field: 'user_nation', title: '民族', sort: true, hide:true}
, {field: 'user_gender', title: '性别', sort: true, hide:true}
, {field: 'user_phone', title: '手机号码', sort: true,templet: function (d) {
return getPhone(d.user_phone)+ "t";
}}
, {field: 'user_cet', title: '证件类型', sort: true, hide:true}
, {field: 'user_card', title: '证件号码', sort: true,templet: function (d) {
return getIdHide(d.user_card);
}}
, {field: 'user_verify', title:'报名状态', sort: true, templet: function (d) {
switch (d.user_verify) {
case "0":
return "<span class='layui-btn layui-btn-xs layui-btn-radius layui-btn-primary layui-border-black'>未报名</span>";
break;
case "1":
return "<span class='layui-btn layui-btn-xs layui-btn-radius layui-btn-primary layui-border-green'>已报名</span>";
break;
case "2":
return "<span class='layui-btn layui-btn-xs layui-btn-radius layui-btn-primary layui-border-blue'>已审核</span>";
break;
}
}
}
, {field: 'user_pay', title:'缴费状态', sort: true, templet: function (d) {
switch (d.user_pay) {
case "0":
return "<span class='layui-btn layui-btn-xs layui-btn-radius layui-btn-primary layui-border-black'>未缴费</span>";
break;
case "1":
return "<span class='layui-btn layui-btn-xs layui-btn-radius layui-btn-primary layui-border-green'>已缴费</span>";
break;
}
}
}
, {field: 'lock', title: '操作', templet: '#checkboxTpl', width:300, align: 'center'}
]]
, error: function(res, err){
//如果是异步请求数据方式,res即为你接口返回的信息。
//如果是直接赋值的方式,res即为:{data: [], count: 99} data为当前页数据、count为数据总长度
console.log(res);
//得到当前页码
console.log(err);
}
});
照片显示
为了图片完整的显示,需要添加对应的CSS样式表,并设置为优先。
.layui-table-cell {
height: auto;
line-height: 20px;
}
.layui-table-cell img {
height: 50%;
max-width: 50%;
}
证件照字段调用,同时对是否包含照片进行条件判断,防止无图导致的非友好化界面。
{field: 'user_photo', title: '证件照', align: 'center', templet: function (d) {
if(d.user_photo == null || d.user_photo == ""){
return '<img src="upload/nopic.png" alt="" width="50" height="70">';
}else{
return '<img src="'+d.user_photo+'" alt="" width="50" height="70">';
}
}
}
隐私加密
{field: 'user_card', title: '证件号码', sort: true,templet: function (d) {
return getIdHide(d.user_card);
}}
//身份证加密
function getIdHide(idCard) {
if (idCard == null) {
return '';
} else {
const temp = idCard.substr(4, 10)
const newIdCard = idCard.replace(temp, '*******')
return newIdCard;
}
}
4.触发事件
事件判断
//触发事件
table.on('toolbar(lockTabel)', function (obj) {
var checkStatus = table.checkStatus(obj.config.id);
switch (obj.event) {
case 'delete':
var data = checkStatus.data;
var arr = [];
for (var i = 0; i < data.length; i++) {
arr.push(data[i].user_id)
}
//删除选中数据;
delAll(arr);
break;
case 'sendSms':
var data = checkStatus.data;
var arr = [];
for (var i = 0; i < data.length; i++) {
arr.push(data[i].user_id)
}
//console.log(arr);
//删除选中数据;
sendSms(arr);
break;
case "sendVerify":
var data = checkStatus.data;
var arr = [];
for (var i = 0; i < data.length; i++) {
arr.push(data[i].user_id)
}
sendVerify(arr);
break;
}
});
事件判断
//删除操作
function delAll(data) {
var lock = false;
layer.confirm('确认要删除吗?', function (index) {
if(!lock) {
if (data.length == 0){
layer.msg('未选择用户', {icon: 1, time: 1000});
return false;
}
lock = true;
$.ajax({
type: "get",
url: "?m=User&a=userDeal&act=del",
async: true,
data: {
user_id: data
},
dataType: "text",
success: function (data) {
layer.msg(data + '删除成功', {icon: 1, time: 1000});
location.replace(location.href);
}
});
}
});
}
后端处理
case "del";
$user_id = get_param('user_id');
if (is_array($user_id)) {
$user_id = implode(",", $user_id);
}
if ($user_id == '') {
die("user_id错误");
}
//删除;
$db->delete($current_table, 'user_id in (' . $user_id . ')');
//操作日志;
addlogs($_COOKIE["admin_name"], '报名信息批量删除,STATUS:OK', '', time(), getip());
break;
- 一键审核
//一键审核;
function sendVerify(data) {
var lock = false;
layer.confirm('确认要审核吗?', function (index) {
if(!lock) {
if (data.length == 0){
layer.msg('未选择用户', {icon: 1, time: 1000});
return false;
}
lock = true;
$.ajax({

url: "?m=User&a=userDeal&act=sendVerify",
async: true,
data: {
user_id: data
},
dataType: "json",
success: function (res) {
if(res.code == 0){
layer.msg(res.msg, {icon: 1, time: 1000});
}else{
layer.msg(res.msg, {icon: 1, time: 1000},function (){
location.replace(location.href);
});
}
}
,error: function (err){
console.log(err)
}
});
}
});
}
后端处理
//一键审核;
case "sendVerify";
$user_id = $_POST['user_id'];
//var_dump($user_id);
if (is_array($user_id)) {
//循环发送信息;
for ($i = 0; $i < count($user_id); $i++) {
$row = $db->fetch($current_table, 'user_name,user_sms,user_phone', array('user_id' => $user_id[$i]), ' user_id DESC');
$db->update($current_table, array('user_verify' => 2), array('user_id' => $user_id[$i]));
}
$res['code'] = 1;
$res['msg'] = "报名审核成功";
die(json_encode_lockdata($res));
} else {
$row = $db->fetch($current_table, 'user_name,user_sms,user_phone', array('user_id' => $user_id), ' user_id DESC');
$db->update($current_table, array('user_verify' => 2), array('user_id' => $user_id));
$res['code'] = 1;
$res['msg'] = $row['user_name'] . "报名审核成功";
die(json_encode_lockdata($res));
}
break;
- 群发短信
//发送短信;
function sendSms(data) {
if (data.length == 0){
layer.msg('未选择用户', {icon: 1, time: 1000});
return false;
}
$.ajax({
type: "post",
url: "?m=User&a=userDeal&act=sendSms",
async: true,
data: {
user_id: data
},
dataType: "json",
success: function (res) {
if(res.code == 0){
layer.msg(res.msg, {icon: 1, time: 1000});
}else{
layer.msg(res.msg, {icon: 1, time: 1000},function (){
location.replace(location.href);
});
}
}
,error: function (err){
console.log(err)
}
});
return false;
}
后端处理
//发送短信;
case "sendSms";
$user_id = $_POST['user_id'];
//var_dump($user_id);
if (is_array($user_id)) {
//循环发送信息;
for ($i = 0; $i < count($user_id); $i++) {
$row = $db->fetch($current_table, 'user_name,user_sms,user_phone', array('user_id' => $user_id[$i]), ' user_id DESC');
if ($row['user_phone'] == NULL || $row['user_phone'] == "") {
$res['code'] = 0;
$res['msg'] = $row['user_name'] . "手机号码有误,无法发送";
die(json_encode_lockdata($res));
}
//发送短信 TODO
//更新发送短信次数
$user_sms = $row['user_sms'] + 1;
$db->update($current_table, array('user_sms' => $user_sms), array('user_id' => $user_id[$i]));
}
$res['code'] = 1;
$res['msg'] = "短信发送成功";
die(json_encode_lockdata($res));
} else {
$row = $db->fetch($current_table, 'user_name,user_sms,user_phone', array('user_id' => $user_id), ' user_id DESC');
if ($row['user_phone'] == NULL || $row['user_phone'] == "") {
$res['code'] = 0;
$res['msg'] = $row['user_name'] . "手机号码有误,无法发送";
die(json_encode_lockdata($res));
}
//发送短信 TODO
//更新发送短信次数
$user_sms = $row['user_sms'] + 1;
$db->update($current_table, array('user_sms' => $user_sms), array('user_id' => $user_id));
$res['code'] = 1;
$res['msg'] = $row['user_name'] . ",短信发送成功";
die(json_encode_lockdata($res));
}
break;
5.执行重载
在筛选框中对应的表单,将相应的值获取,传递给API,进行筛选后查询。
//执行重载;
var $ = layui.$, active = {
reload: function () {
table.reload('searchTable', {
page: {curr: 1}
, where: {
user_work: $("#major_name").val().split(',')[1],
user_class: $("#sub_name").val(),
user_verify: $('#user_verify').val(),
user_pay: $('#user_pay').val(),
user_name: $('#user_name').val(),
user_ticket: $('#user_ticket').val()
}
});
}
};
$('.demoTable .layui-btn').on('click', function () {
var type = $(this).data('type');
active[type] ? active[type].call(this) : '';
});
6.操作按钮
使用table模块中id=”checkboxTpl”和id=”toolbarDemo“对应的位置调用按钮即可。
<script type="text/html" id="checkboxTpl">
{if $smarty.cookies.admin_menu eq "1"}
{literal}<a class="layui-btn layui-btn-xs layui-btn-normal" href="javascript:;" onclick="sendSms('{{d.user_id}}')"><i class="layui-icon layui-icon-cellphone"></i> 短信({{d.user_sms}})</a>{/literal}
{/if}
{literal}
<a class="layui-btn layui-btn-xs" href="index.php?m=Index&a=indexDeal&act=inspect&user_id={{d.user_id}}" target="_blank">准考证</a>
<a class="layui-btn layui-btn-xs" href="javascript:;" onclick="x_admin_show('审核','?m=User&a=userEdit&act=show&user_id={{d.user_id}}','','')">审核</a>
<a class="layui-btn layui-btn-xs layui-btn-warm" onclick="x_admin_show('修改密码','?m=User&a=userPass&act=pass&user_id={{d.user_id}}','','')" title="修改密码" href="javascript:;">密码</a>
{/literal}
</script>
<script type="text/html" id="toolbarDemo">
<button class="layui-btn layui-btn-sm layui-btn-danger" lay-event="delete"><i class="layui-icon layui-icon-delete"></i>批量删除</button>
<button class="layui-btn layui-btn-sm" lay-event="sendVerify"><i class="layui-icon layui-icon-auz"></i> 报名审核</button>
<button class="layui-btn layui-btn-sm layui-btn-normal" lay-event="sendSms"><i class="layui-icon layui-icon-cellphone"></i> 发送短信</button>
</script>
总结
layui-table模块涉及:
- 复选框事件:点击复选框时触发,回调函数返回一个 object 参数;
- 单元格工具事件:比如编辑、删除,这时可借助单元格工具事件(tool)来实现;
- 头部工具栏事件:点击头部工具栏区域设定了属性为 lay-event=“” 的元素时触发;
- 导出任意数据: table 的工具栏内置了数据导出按钮,但有时你可能需要通过方法去导出任意数据,那么可以借助以下方法:table.exportFile(id, data, obj);
- 自动化渲染的重载;
