README

在 Laravel 上快速生成简单的 PDF 报告(使用 barryvdh/laravel-dompdfbarryvdh/laravel-snappy)或 CSV / Excel 报告(使用 Maatwebsite/Laravel-Excel

此包提供简单的 PDF、CSV 和 Excel 报告生成器,以加快您的工作流程

安装

将包添加到您的 composer

composer require coolsam/laravel-report-generator

如果您正在运行 Laravel > 5.5,那么您需要做的就是这一点。如果您正在使用 Laravel < 5.5,请在 config/app.php 中的 providers 数组中添加 ServiceProvider

Coolsam\ReportGenerator\ServiceProvider::class,

可选,您可以将此添加到 config/app.php 中的 aliases 数组

'PdfReport' => Coolsam\ReportGenerator\Facades\PdfReportFacade::class,
'ExcelReport' => Coolsam\ReportGenerator\Facades\ExcelReportFacade::class,
'CSVReport' => Coolsam\ReportGenerator\Facades\CSVReportFacade::class,

为了在生成 PDF 报告时获得更好的速度,我建议您使用 laravel snappy 包。要使用 laravel snappy,您应该安装 wkhtmltopdf 来与此包一起使用 (跳转到 wkhtmltopdf 安装)

信息

此包可以使用 cursorchunk 方法(Eloquent / Query Builder),因此它比 chunk 处理大数据更快,并最小化内存使用。

此外,您可以使用 PdfReportExcelReportCSVReport 门面来缩短已注册为别名的代码。

示例显示 PDF 代码

use PdfReport;

public function displayReport(Request $request)
{
    $fromDate = $request->input('from_date');
    $toDate = $request->input('to_date');
    $sortBy = $request->input('sort_by');

    $title = 'Registered User Report'; // Report title

    $meta = [ // For displaying filters description on header
        'Registered on' => $fromDate . ' To ' . $toDate,
        'Sort By' => $sortBy
    ];

    $queryBuilder = User::select(['name', 'balance', 'registered_at']) // Do some querying..
                        ->whereBetween('registered_at', [$fromDate, $toDate])
                        ->orderBy($sortBy);

    $columns = [ // Set Column to be displayed
        'Name' => 'name',
        'Registered At', // if no column_name specified, this will automatically seach for snake_case of column name (will be registered_at) column from query result
        'Total Balance' => 'balance',
        'Status' => function($result) { // You can do if statement or any action do you want inside this closure
            return ($result->balance > 100000) ? 'Rich Man' : 'Normal Guy';
        }
    ];

    // Generate Report with flexibility to manipulate column class even manipulate column value (using Carbon, etc).
    return PdfReport::of($title, $meta, $queryBuilder, $columns)
                    ->editColumn('Registered At', [ // Change column class or manipulate its data for displaying to report
                        'displayAs' => function($result) {
                            return $result->registered_at->format('d M Y');
                        },
                        'class' => 'left'
                    ])
                    ->editColumns(['Total Balance', 'Status'], [ // Mass edit column
                        'class' => 'right bold'
                    ])
                    ->showTotal([ // Used to sum all value on specified column on the last table (except using groupBy method). 'point' is a type for displaying total with a thousand separator
                        'Total Balance' => 'point' // if you want to show dollar sign ($) then use 'Total Balance' => '$'
                    ])
                    ->limit(20) // Limit record to be showed
                    ->stream(); // other available method: download('filename') to download pdf / make() that will producing DomPDF / SnappyPdf instance so you could do any other DomPDF / snappyPdf method such as stream() or download()
}

注意:对于下载到 Excel / CSV,只需将 PdfReport 门面更改为 ExcelReport / CSVReport 门面,无需进行更多修改

数据处理

$columns = [
    'Name' => 'name',
    'Registered At' => 'registered_at',
    'Total Balance' => 'balance',
    'Status' => function($customer) { // You can do data manipulation, if statement or any action do you want inside this closure
        return ($customer->balance > 100000) ? 'Rich Man' : 'Normal Guy';
    }
];

将与以下相同的结果产生

$columns = [
    'Name' => function($customer) {
        return $customer->name;
    },
    'Registered At' => function($customer) {
        return $customer->registered_at;
    },
    'Total Balance' => function($customer) {
        return $customer->balance;
    },
    'Status' => function($customer) { // You can do if statement or any action do you want inside this closure
        return ($customer->balance > 100000) ? 'Rich Man' : 'Normal Guy';
    }
];

报告输出

Report Output with Grand Total

使用此操作,您可以执行一些 预加载关系

$post = Post::with('comments')->where('active', 1);

$columns = [
    'Post Title' => function($post) {
        return $post->title;
    },
    'Slug' => 'slug',
    'Latest Comment' => function($post) {
        return $post->comments->first()->body;
    }
];

带有 Group By 的示例代码

或者,您可以使用 groupBy 方法按组总计所有记录

    ...
    // Do some querying..
    $queryBuilder = User::select(['name', 'balance', 'registered_at'])
                        ->whereBetween('registered_at', [$fromDate, $toDate])
                        ->orderBy('registered_at', 'ASC'); // You should sort groupBy column to use groupBy() Method

    $columns = [ // Set Column to be displayed
        'Registered At' => 'registered_at',
        'Name' => 'name',
        'Total Balance' => 'balance',
        'Status' => function($result) { // You can do if statement or any action do you want inside this closure
            return ($result->balance > 100000) ? 'Rich Man' : 'Normal Guy';
        }
    ];

    return PdfReport::of($title, $meta, $queryBuilder, $columns)
                    ->editColumn('Registered At', [
                        'displayAs' => function($result) {
                            return $result->registered_at->format('d M Y');
                        }
                    ])
                    ->editColumn('Total Balance', [
                        'class' => 'right bold',
                        'displayAs' => function($result) {
                            return thousandSeparator($result->balance);
                        }
                    ])
                    ->editColumn('Status', [
                        'class' => 'right bold',
                    ])
                    ->groupBy('Registered At') // Show total of value on specific group. Used with showTotal() enabled.
                    ->showTotal([
                        'Total Balance' => 'point'
                    ])
                    ->stream();

请注意,在使用此 Group By 方法之前,请先通过查询对 GROUP BY 列进行排序。
