【背景】

大早上的，发现昨天的那个批量发短信，需要进行条件筛选，不如：按部门发、按项目发、按选择的客户发，这时候就需要进行多条件筛选。同时发现，多条件筛选应用到很多场景，比如：下载数据、任务设置等。这个文档主要解决批量导出数据。

然后网上一搜，发现了这个朋友的帖子，真是不错：fastadmin 导出_fastadmin导出大量数据-CSDN博客

顺带记录下来。

【操作步骤】

1. JS增加处理函数
    

   $(document).on("click", ".btn-export", function () {
                   var ids = Table.api.selectedids(table);
                   var page = table.bootstrapTable('getData');
                   var all = table.bootstrapTable('getOptions').totalRows;
                   console.log(ids, page, all);
                   Layer.confirm("请选择导出的选项<form action='" + Fast.api.fixurl("shop/order/export") + "' method='post' target='_blank'><input type='hidden' name='ids' value='' /><input type='hidden' name='filter' ><input type='hidden' name='op'><input type='hidden' name='search'><input type='hidden' name='columns'></form>", {
                       title: '导出数据',
                       btn: ["选中项(" + ids.length + "条)", "本页(" + page.length + "条)", "全部(" + all + "条)"],
                       success: function (layero, index) {
                           $(".layui-layer-btn a", layero).addClass("layui-layer-btn0");
                       }
                       , yes: function (index, layero) {
                           submitForm(ids.join(","), layero);
                           return false;
                       }
                       ,
                       btn2: function (index, layero) {
                           var ids = [];
                           $.each(page, function (i, j) {
                               ids.push(j.id);
                           });
                           submitForm(ids.join(","), layero);
                           return false;
                       }
                       ,
                       btn3: function (index, layero) {
                           submitForm("all", layero);
                           return false;
                       }
                   })
               });
   var submitForm = function (ids, layero) {
                   var options = table.bootstrapTable('getOptions');
                   console.log(options);
                   var columns = [];
                   $.each(options.columns[0], function (i, j) {
                       if (j.field && !j.checkbox && j.visible && j.field != 'operate') {
                           columns.push(j.field);
                       }
                   });
                   var search = options.queryParams({});
                   $("input[name=search]", layero).val(options.searchText);
                   $("input[name=ids]", layero).val(ids);
                   $("input[name=filter]", layero).val(search.filter);
                   $("input[name=op]", layero).val(search.op);
                   $("input[name=columns]", layero).val(columns.join(','));
                   $("form", layero).submit();
               };

   
    
2. 模板增加按钮
    

   <a href="javascript:;" class="btn btn-success btn-export {:$auth->check('shop_order/export')?'':'hide'}" title="{:__('Export')}" id="btn-export-file"><i class="fa fa-download"></i> {:__('Export')}</a>

   
    
3. 控制器增加操作

 
public function export()
{
    if ($this->request->isPost()) {
        set_time_limit(0);
        $search = $this->request->post('search');
        $ids = $this->request->post('ids');
        $filter = $this->request->post('filter');
        $op = $this->request->post('op');
        $columns = $this->request->post('columns');
        $excel = new \PHPExcel();
        $excel->getProperties()
            ->setCreator("FastAdmin")
            ->setLastModifiedBy("FastAdmin")
            ->setTitle("标题")
            ->setSubject("Subject");
        $excel->getDefaultStyle()->getFont()->setName('Microsoft Yahei');
        $excel->getDefaultStyle()->getFont()->setSize(12);
        
        $this->sharedStyle = new \PHPExcel_Style();
        $this->sharedStyle->applyFromArray(
            array(
                'fill'      => array(
                    'type'  => \PHPExcel_Style_Fill::FILL_SOLID,
                    'color' => array('rgb' => '000000')
                ),
                'font'      => array(
                    'color' => array('rgb' => "000000"),
                ),
                'alignment' => array(
                    'vertical'   => \PHPExcel_Style_Alignment::VERTICAL_CENTER,
                    'horizontal' => \PHPExcel_Style_Alignment::HORIZONTAL_CENTER,
                    'indent'     => 1
                ),
                'borders'   => array(
                    'allborders' => array('style' => \PHPExcel_Style_Border::BORDER_THIN),
                )
            ));
            
        $worksheet = $excel->setActiveSheetIndex(0);
        $worksheet->setTitle('标题');
        $whereIds = $ids == 'all' ? '1=1' : ['id' => ['in', explode(',', $ids)]];
        $this->request->get(['search' => $search, 'ids' => $ids, 'filter' => $filter, 'op' => $op]);
        list($where, $sort, $order, $offset, $limit) = $this->buildparams();
        
        //$columns 是得到的字段，可以在这里写上自己的逻辑，比如删除或添加其他要写的字段
        
        $line = 1;
        $list = [];
        $this->model
            ->field($columns)
            ->where($where)
            ->where($whereIds)
            ->chunk(100, function ($items) use (&$list, &$line, &$worksheet) {
                global $userName;
                global $QuyuName;
                $styleArray = array(
                    'font' => array(
                        'bold'  => true,
                        'color' => array('rgb' => 'FF0000'),
                        'size'  => 15,
                        'name'  => 'Verdana'
                    ));
                $list = $items = collection($items)->toArray();
                foreach ($items as $index => $item) {
                    $line++;
                    $col = 0;
                    foreach ($item as $field => $value) {
                        //这样写能防止手机号被excel表格手机号数据自动科学计数，其他同理
                        if($field == "mobile"){
                            $value = " ".$value;
                        }
                        $worksheet->setCellValueByColumnAndRow($col, $line, $value);
                        $worksheet->getColumnDimension('B')->setAutoSize(true);//这样写代表B列自动列宽     
                        $worksheet->getStyleByColumnAndRow($col, $line)->getNumberFormat()->setFormatCode(\PHPExcel_Style_NumberFormat::FORMAT_TEXT);
                        $worksheet->getCellByColumnAndRow($col, $line)->getStyle()->applyFromArray($styleArray);
                        $col++;
                    }
                }
            });
        $first = array_keys($list[0]);
        foreach ($first as $index => $item) {
            $worksheet->setCellValueByColumnAndRow($index, 1, __($item));
        }
        $excel->createSheet();
        // Redirect output to a client’s web browser (Excel2007)
        $title = date("YmdHis");
        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
        header('Content-Disposition: attachment;filename="' . $title . '.xlsx"');
        header('Cache-Control: max-age=0');

        $objWriter = \PHPExcel_IOFactory::createWriter($excel, 'Excel2007');
        $objWriter->save('php://output');exit;
        return;
    }
}

真是好事多磨，为什么同样一个项目，有的报价十几万甚至更高，而有的人几百块？哪里出了问题？

因为：

所有的产品都是明码标价的！所谓一分价钱一分货！

而人100%心态就是贪便宜！所以，就给骗子创造了很好的机会，也正因为如此，我从来不同情那些韭菜(被骗的人)！

而一些根本没有开发能力的人，更是无耻至极，这部分大多数是十几年前从那些做网站卖域名的企业做销售出来的！全靠骗客户！

现在又出来注册个皮包公司，继续骗客户！

大家小心……
