thinkphp导出excel

使用库：PHPOffice/PHPExcel https://github.com/PHPOffice/PHPExcel

以下为核心代码：可根据具体需求更改。

1、控制器文件添加export方法

use PhpOffice\PhpSpreadsheet\Helper\Sample;
use PhpOffice\PhpSpreadsheet\IOFactory;
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
use PhpOffice\PhpSpreadsheet\Cell\Coordinate;
use PhpOffice\PhpSpreadsheet\Worksheet\PageSetup;
use PhpOffice\PhpSpreadsheet\Cell\DataType;
use PhpOffice\PhpSpreadsheet\Style\Fill;
use PhpOffice\PhpSpreadsheet\Style\Color;
use PhpOffice\PhpSpreadsheet\Style\Alignment;
use PhpOffice\PhpSpreadsheet\Style\Border;
use PhpOffice\PhpSpreadsheet\Style\NumberFormat;

public function export()
{
    if ($this->request->isPost()) {
        /**
             * 设置程序执行时间的函数
             * 为零说明永久执行直到程序结束
             */
        set_time_limit(0);
        $ids = $this->request->post('ids');
        $columns = $this->request->post('columns');
        $excel = new Spreadsheet();
        $excel->getProperties()
            ->setCreator("FastAdmin")
            ->setLastModifiedBy("FastAdmin")
            ->setTitle("标题")
            ->setSubject("Subject");
        $excel->getDefaultStyle()->getFont()->setName('Microsoft Yahei');
        $excel->getDefaultStyle()->getFont()->setSize(12);
        $excel->getDefaultStyle()->applyFromArray(
            array(
                'fill' => array(
                    'type' => Fill::FILL_SOLID,
                    'color' => array('rgb' => '000000')
                ),
                'font' => array(
                    'color' => array('rgb' => "000000"),
                ),
                'alignment' => array(
                    'vertical' => Alignment::VERTICAL_CENTER,
                    'horizontal' => Alignment::HORIZONTAL_CENTER,
                    'indent' => 1
                ),
                'borders' => array(
                    'allborders' => array('style' => Border::BORDER_THIN),
                )
            ));

        $worksheet = $excel->setActiveSheetIndex(0);
        $worksheet->setTitle('标题');
        // 配合js,如果提交参数为all,则导出所有数据
        $whereIds = $ids == 'all' ? '1=1' : ['id' => ['in', explode(',', $ids)]];
        $line = 1;
        $list = [];
        $this->model
            ->field($columns)
            ->where($whereIds)
            // 使用分批查询
            /**
                 * 注意点：如果使用到了with关联查询，
                 * 需要指定chunk分批处理的字段名（形参）
                 * 例如：fa_student.id fa_student表的id
                 * 默认为id,如果关联表也有id字段，则会抛出异常
                 * SQLSTATE[23000]: Column ‘id’ in where clause is ambiguous
                 */
            ->chunk(100, function ($items) use (&$list, &$line, &$worksheet) {
                $styleArray = array(
                    'font' => array(
                        'color' => array('rgb' => '000000'),
                        'size' => 12,
                        'name' => 'Verdana'
                    ));
                $list = $items = collection($items)->toArray();
                foreach ($items as $key => $v) {
                    foreach ($v as $k => $ele) {
                        $tmparray = explode("_text", $k);
                        if (count($tmparray) > 1) {
                            $items[$key][$tmparray[0]] = $ele;
                            unset($items[$key][$k]);
                        }
                    }
                }
                foreach ($items as $index => $item) {
                    $line++;
                    $col = 0;
                    foreach ($item as $field => $value) {
                        $worksheet->setCellValueByColumnAndRow($col, $line, $value);
                        $worksheet->getStyleByColumnAndRow($col, $line)->getNumberFormat()->setFormatCode(NumberFormat::FORMAT_TEXT);
                        $worksheet->getCellByColumnAndRow($col, $line)->getStyle()->applyFromArray($styleArray);
                        $col++;
                    }
                }
            });
        // 获取查询到记录的字段值
        $first = array_keys($list[0]);
        /**
             * 去除带_text的字段
             * "category_text"
             * "status_text"
             */
        foreach ($first as $k => $ele) {
            $tmparray = explode("_text", $ele);
            if (count($tmparray) > 1) {
                unset($first[$k]);
            }
        }

        foreach ($first as $index => $item) {
            $worksheet->setCellValueByColumnAndRow($index, 1, __($item));
        }
        $excel->createSheet();
        // Redirect output to a client’s web browser (Excel2007)
        // 保存文件名
        $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');
        // If you're serving to IE 9, then the following may be needed
        header('Cache-Control: max-age=1');
        // If you're serving to IE over SSL, then the following may be needed
        header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
        header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT'); // always modified
        header('Cache-Control: cache, must-revalidate'); // HTTP/1.1
        header('Pragma: public'); // HTTP/1.0
        $objWriter = IOFactory::createWriter($excel, 'Xlsx');
        $objWriter->save('php://output');
        return;
    }
}

2、html页面添加后按钮，在js中绑定按钮事件：

var table = $('form[role=form]');
//自定义export开始
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=columns]", layero).val(columns.join(','));
	$("form", layero).submit();
};
$(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("test/export") + "' method='post' target='_blank'><input type='hidden' name='ids' value='' /><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)"],
	// btn: ["选中项(" + ids.length + "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;
}
})
});
