数据导出
|
|||
|
|
=======
|
|||
|
|
|
|||
|
|
`model-grid`内置的导出功能只是实现了简单的csv格式文件的导出，如果遇到文件编码问题或者满足不了自己需求的情况，可以按照下面的步骤来自定义导出功能
|
|||
|
|
|
|||
|
|
本示例用[Laravel-Excel](https://github.com/Maatwebsite/Laravel-Excel)作为excel操作库，当然也可以使用任何其他excel库
|
|||
|
|
|
|||
|
|
首先安装好它：
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
composer require maatwebsite/excel:~2.1.0
|
|||
|
|
|
|||
|
|
php artisan vendor:publish --provider="Maatwebsite\Excel\ExcelServiceProvider"
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
然后新建自定义导出类，比如`app/Admin/Extensions/ExcelExpoter.php`:
|
|||
|
|
```php
|
|||
|
|
<?php
|
|||
|
|
|
|||
|
|
namespace App\Admin\Extensions;
|
|||
|
|
|
|||
|
|
use Encore\Admin\Grid\Exporters\AbstractExporter;
|
|||
|
|
use Maatwebsite\Excel\Facades\Excel;
|
|||
|
|
|
|||
|
|
class ExcelExpoter extends AbstractExporter
|
|||
|
|
{
|
|||
|
|
public function export()
|
|||
|
|
{
|
|||
|
|
Excel::create('Filename', function($excel) {
|
|||
|
|
|
|||
|
|
$excel->sheet('Sheetname', function($sheet) {
|
|||
|
|
|
|||
|
|
// 这段逻辑是从表格数据中取出需要导出的字段
|
|||
|
|
$rows = collect($this->getData())->map(function ($item) {
|
|||
|
|
return array_only($item, ['id', 'title', 'content', 'rate', 'keywords']);
|
|||
|
|
});
|
|||
|
|
|
|||
|
|
$sheet->rows($rows);
|
|||
|
|
|
|||
|
|
});
|
|||
|
|
|
|||
|
|
})->export('xls');
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
然后在`model-grid`中使用这个导出类：
|
|||
|
|
```php
|
|||
|
|
|
|||
|
|
use App\Admin\Extensions\ExcelExpoter;
|
|||
|
|
|
|||
|
|
$grid->exporter(new ExcelExpoter());
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
