第15课 栏目的排序处理(组件化) Thinkphp5商城第四季

目录

• [TOC]

要实现的功能

用表单里的提交过来的sort数据,批量修改表里的排序值

界面效果:

思路:

1. 视图层表单提交数据主键=>sort值
2. 控制器调用扩展类里的 public function cateSort($data, $obj) 方法
   
   //处理栏目排序 $data数组,$obj是实例化的表的对象
3. cateSort验证数据并修改表里sort的值,如果提交的不是大于0的整数,就报错.

视图层

提交的数据排序数据是要 主键=>sort值

<input type="text" style="width:60px; text-align:center;" name="sort[{$cate.id}]" value="{$cate.sort}" />

 <form action="" method="post">
                    <table class="table table-bordered table-hover">
                        <thead class="">
                            <tr>
                                <th class="text-center" width="8%">ID</th>
                                <th class="text-center">分类名称</th>
                                <th class="text-center" width="10%">类型</th>

打印提交的数据:

D:\xampp\htdocs\shop\thinkphp\library\think\Debug.php:165:

array (size=1)

'sort' =>

array (size=17)

20 => string '4' (length=1)

22 => string '3' (length=1)

21 => string '3' (length=1)

1 => string '2' (length=1)

3 => string '12' (length=2)

2 => string '11' (length=2)

4 => string '55' (length=2)

5 => string '54' (length=2)

7 => string '53' (length=2)

16 => string '52' (length=2)

17 => string '51' (length=2)

23 => string '2' (length=1)

25 => string '50' (length=2)

24 => string '50' (length=2)

19 => string '1' (length=1)

18 => string '1' (length=1)

26 => string '1' (length=1)

控制器里:

public function lst()
    {
        $Category = new Catetree();
        $CategoryObj = db('Category');
        if (request()->isPost()) {
            $data = input('post.');
            $cateres = $Category->cateSort($data['sort'], $CategoryObj);
            if ($cateres === false) {
                $this->error('只能填写大于0的数字');
            }
            $this->success('排序成功！', url('lst'));
        }
        $CategoryRes = $CategoryObj->order('sort DESC')->select();
        $CategoryRes = $Category->Catetree($CategoryRes);
        $this->assign([
            'CategoryRes' => $CategoryRes,
        ]);
        return view('list');
    }

扩展函数里

D:\xampp\htdocs\shop\extend\catetree\Catetree.php

<?php
namespace catetree;

use think\Validate;

class Catetree
{
   //处理栏目排序 $data数组,$obj是实例化的表的对象
    public function cateSort($data, $obj)
    {
        foreach ($data as $k => $v) {
             //数组里的排序值只能填写大于0的数字
            $is_num = (!empty(intval($v)) && $v > 0 && Validate::is(intval($v), 'integer')) ? 1 : 0;
            // dump($is_num);
            if ($is_num == 0) {
                return false;
            }
            $obj->update(['id' => $k, 'sort' => $v]);
        }
    }
