销售合同金额数据从Excel导入

一.业务需求

1.新增了销售合同金额的字段，但是老数据没有这个字段；所以销售合同金额从销售合同附件的各品种金额之和。

2.制作好excel字段模板，将此模板发送给销售业务部门来统计并完成excel表格数据

二.产品设计

无

三.UI设计

无

四.程序设计

1.使用php-excel插件封装ExcelHelper类，包括导出数据到excel和将excel数据导入数据库

<?php

namespace core\components;

use PHPExcel;
use PHPExcel_IOFactory;
use PHPExcel_Style_Alignment;
use PHPExcel_Reader_Excel5;
use PHPExcel_RichText;

class MyExcelHelper extends \yii\base\Component{

    /**
     * 将二维数组的数据转化为excel表格导出
     * @param $data
     * @param $excel_name
     * @param $headers
     * @param $options
     */
    public static function array2excel($data, $excel_name, $headers, $options, $style_options){
        $objPHPExcel = new PHPExcel();
        ob_start();

        if (!isset($options['creator'])){
            $objPHPExcel->getProperties()->setCreator('creator');
        }else{

                    'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER
                ]
            ]);
            if (isset($style_options['h_align'][$header_key])){
                if ($style_options['h_align'][$header_key] == 'left'){
                    $h_align = PHPExcel_Style_Alignment::HORIZONTAL_LEFT;
                }elseif ($style_options['h_align'][$header_key] == 'center'){

                ]);
            }
        }

        $data_row_index = 2;
        foreach ($data as $row_index => $row){
            $data_keys = array_keys($row);
            foreach ($data_keys as $column_index => $data_key){
                if ($column_index>=26){
                    throw new \yii\base\Exception('EXCEL表格超过26列');
                }
                $index_ascii = $column_index + 65;
                $index_chr = chr($index_ascii);
                $value = $row[$data_key];
                $objPHPExcel->setActiveSheetIndex(0)->setCellValue($index_chr . $data_row_index, $value);
            }
            $data_row_index++;
        }

        if (isset($options['summary'])){
            $summary_keys = array_keys($options['summary']);
            foreach ($summary_keys as $summary_index => $summary_key){

        $objPHPExcel->setActiveSheetIndex(0);

        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');

        ob_end_clean();

        header('Content-Type: application/vnd.ms-excel');
        header('Content-Disposition: attachment;filename="' . $excel_name . '.xls"');
        header('Cache-Control: max-age=0');

        $objWriter->save('php://output');
        exit;
    }

    /**
     * 将excel表格转化为二维数组的数据
     * @param $excel_path
     * @param $data
     * @param $header
     */
    public static function excel2array($excel_path, $header_keys){

        if(!file_exists($excel_path)){
            throw new \yii\base\Exception('该EXCEL不存在！');
        }
        $PHPReader = new \PHPExcel_Reader_Excel2007();
        if(!$PHPReader->canRead($excel_path)){
            $PHPReader = new PHPExcel_Reader_Excel5();
            if(!$PHPReader->canRead($excel_path)){
                throw new \yii\base\Exception('该EXCEL不可读');
            }
        }

        $PHPExcel = $PHPReader->load($excel_path);
        $currentSheet = $PHPExcel->getSheet(0);

        $max_column_index = $currentSheet->getHighestColumn();
        $max_row_index = $currentSheet->getHighestRow();

        $data = array();
        for($row_index=2; $row_index<=$max_row_index; $row_index++ ){
            for($column_chr='A'; $column_chr<=$max_column_index; $column_chr++){
                $column_ord = ord($column_chr);
                $column_index = $column_ord - 65;
                $key = $column_chr.$row_index;
                $value = $currentSheet->getCell($key)->getValue();
                if($value instanceof PHPExcel_RichText){
                    $value = $value->__toString();
                }

                $data[$row_index-1][$header_keys[$column_index]] = $value;
            }
        }
        return $data;
    }
}

　　

2.使用命令模式编写控制台程序将excel的数据导入到数据库

<?php

namespace console\controllers;

use yii\console\Controller;
use Yii;

class SalesContractController extends Controller
{
    public function actionUploadExcel(){
        $excel_path = './console/excels/sales_contract.xlsx';
        $header_keys = ['sales_contract_code', 'sales_customers_name', 'sales_contract_sum_weight'];
        $data = \core\components\MyExcelHelper::excel2array($excel_path, $header_keys);
        if (!empty($data)){
            foreach ($data as $sales_contract){
                $salesContractModel = \core\models\SalesContract::find()->where([
                    'sales_contract_code'=>$sales_contract['sales_contract_code'],
                ])->one();
                if (!empty($salesContractModel)){
                    $salesContractModel->sales_contract_sum_weight = \common\models\Base::weightBcmul($sales_contract['sales_contract_sum_weight']);
                    if ($salesContractModel->save()){
                        echo PHP_EOL.'导入销售合同'.$sales_contract['sales_contract_code'].'更新数据成功！';
                    }
                }
            }
        }
    }
}

　　

五.上线

上传excel到制定目录：

运行命令如下：

php yii sales-contract/upload-excel

　　运行结果如下：
