Yii使用PhpSpreadsHeet 生成 Excel 和导入 Excel 前后端分离版和未分离版

前提下载PhpSpreadsHeet依赖 ：

composer require phpoffice/phpspreadsheet

1.开始正题：

1.1 这里使用这个数据库 检测工具表：

DROP TABLE IF EXISTS `test_tool`;
CREATE TABLE `test_tool` (
  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '检测工具id',
  `tool_number` varchar(50) NOT NULL COMMENT '工具编号',
  `tool_name` varchar(50) NOT NULL COMMENT '工具名称',
  `tool_brand` varchar(50) DEFAULT NULL COMMENT '工具品牌',
  `tool_class` varchar(50) NOT NULL COMMENT '工具分类',
  `tool_calibration_cycle` varchar(50) NOT NULL COMMENT '工具校验周期',
  `tool_status` varchar(50) NOT NULL COMMENT '工具状态',
  `tool_functions` text NOT NULL COMMENT '工具功能',
  `tool_scope` varchar(255) DEFAULT NULL COMMENT '工具适用范围',
  `purchase_time` datetime DEFAULT NULL COMMENT '购置日期',
  `supplier` varchar(50) DEFAULT NULL COMMENT '供应商',
  `storage_address` varchar(255) DEFAULT NULL COMMENT '存放地址',
  `tool_notes` text COMMENT '工具备注',
  `created_time` datetime DEFAULT CURRENT_TIMESTAMP COMMENT '记录创建时间',
  `updated_time` datetime DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP COMMENT '记录更新时间',
  `tool_file` varchar(255) DEFAULT NULL COMMENT '工具图片地址',
  `create_by` int(11) DEFAULT NULL COMMENT '记录创建者user_id',
  `updated_by` int(11) DEFAULT NULL COMMENT '记录更新者user_id',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=15 DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC;

INSERT INTO `test_tool` VALUES ('1', '', '弛度观测仪', null, '1', '7', '1', '剪指甲', '全部', null, null, null, '使用方便', '2020-05-06 17:35:44', '2020-05-20 10:05:34', '/uploads/5ec4906e2e768_login_bg.jpg', null, null);
INSERT INTO `test_tool` VALUES ('2', '', '电力测量工具', null, '1', '7', '1', '剪指甲', '全部', null, null, null, '使用方便', '2020-05-06 17:36:07', '2020-05-20 09:31:55', '', null, null);
INSERT INTO `test_tool` VALUES ('3', '', '弧垂弛度观测仪', null, '1', '7', '1', '剪指甲', '全部', null, null, null, '使用方便', '2020-05-06 17:36:11', '2020-05-20 09:31:55', '', null, null);

INSERT INTO `test_tool` VALUES ('5', '', '电磁式电压互感器', null, '1', '7', '1', '剪指甲', '全部', null, null, null, '使用方便', '2020-05-06 17:36:17', '2020-05-20 09:31:55', '', null, null);

1.2 创建ExitController 这个控制器名字随便你们这么写。

<?php


namespace app\controllers;

use app\models\TestTool;
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Style\Color;
use PhpOffice\PhpSpreadsheet\Style\Fill;

use yii\web\Controller;

class ExitController extends  Controller
{
    
    
    /**

     */
    public function actionSamples()
    {
    
    
        $spreadsheet = new Spreadsheet();
        $worksheet = $spreadsheet->getActiveSheet();
        //图片
        $drawing = new \PhpOffice\PhpSpreadsheet\Worksheet\Drawing();
        //设置工作表标题名称
        //$worksheet->setTitle('phpspreadsheet——检测工具');
        //表头   1
        $spreadsheet->getActiveSheet()->setTitle('检测工具');
        //设置单元格内容
        $k=1;
        $worksheet->setCellValue('A' . $k, 'id');

        //背景颜色
        $worksheet->getStyle('A1:N1')->getFill()->setFillType(Fill::FILL_SOLID)->getStartColor()->setARGB('FFFF0000');// 设置背景色
        //设置单元格样式
        $worksheet->getStyle('A1:N1')->applyFromArray($styleArray)->getFont()->setSize(12);
        //访问的数据库
        $jzInfo = TestTool::find()->all();
        $len = count($jzInfo);
        $j = 0;
        for ($i=0; $i < $len; $i++) {
    
    
            $j = $i + 2; //从表格第3行开始
            $worksheet->setCellValueByColumnAndRow(1, $j, $jzInfo[$i]['id']);
            $worksheet->setCellValueByColumnAndRow(2, $j, $jzInfo[$i]['tool_number']);
            $worksheet->setCellValueByColumnAndRow(3, $j, $jzInfo[$i]['tool_name']);
            $worksheet->setCellValueByColumnAndRow(4, $j, $jzInfo[$i]['tool_brand']);

            $worksheet->setCellValueByColumnAndRow(14, $j, $jzInfo[$i]['tool_file']);
        }
        $styleArrayBody = [

        //设置文件前缀
        $filename = date('Y-m-d', time()) . rand(1000, 9999);
        $filename = $filename.'无忧巡检工具列表.xlsx';
        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
        header('Content-Disposition: attachment;filename="'.$filename.'"');
        header('Cache-Control: max-age=0');
        $writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx');
        $writer->save('php://output');
    }
    public function actionImp()
    {
    
    
        
    }
}

1.3访问url 我本机是具体看你们自己的:

http://localhost/yii-excal/basic/web/index.php?r=exit/samples

就会下载这个 无忧巡检工具列表.xlsx

这里面的数据就是来自数据库，具体看我上面的代码。

1.4 创建其他有导入和导出的页面方式。

         Excel::exportExcel($data,$title);
    }
}

1.4.3 创建UploadForm 因为使用到了文件上传

<?php


namespace app\models;


class UploadForm extends \yii\base\Model
{
    
    

    /**
     * @var
     */
    public $file;

    /**
     * @return array the validation rules.
     */
    public function rules()
    {
    
    
        return [
            [['file'], 'file'],
        ];
    }
}

1.4.4 创建视图 viwes/test/ index.php

<?php
use yii\bootstrap\ActiveForm;
?>

<!--导入表格-->
<h2>导入表格</h2>
<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data'],'action' => ['import_excel_data'],'method'=>'post']) ?>

<?= $form->field($file, 'file')->fileInput() ?>

<button>导入表格</button>

<?php ActiveForm::end() ?>
<!--下载表格-->
<a  href="index.php?r=test/export_excel_data">下载表格</a>

完成以上就是可以访问：

http://localhost/yii-excal/basic/web/index.php?r=test/index

就可以完成导入和导出。

1.5创建前后端分离的api方式：

使用导入前下载一个模板 然后再模板中输入 对应的数据 就可以说进行导入：

1.5.1创建ExcelTools

导出和上面的的导出基本以上这里就不展示的。

具体调试api 大家百度下PostMan excel 接口调试方式就是可以。
