README

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

此包提供简单的PDF、CSV和Excel报表生成器，以加快您的流程。它还允许您无缝地stream（流式传输）、download（下载）或store（存储）报表。

版本

在这里找到chunk和cursor的比较

安装

将包添加到您的composer

composer require jimmyjs/laravel-report-generator

如果您正在运行Laravel > 5.5，则只需这样做。如果您正在使用Laravel < 5.5，请在config/app.php中的providers数组中添加ServiceProvider

Jimmyjs\ReportGenerator\ServiceProvider::class,

可选，您可以将此添加到config/app.php中的aliases数组

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

可选，您可以将配置文件发布（然后它将在config/report-generator.php中可用）

php artisan vendor:publish --provider="Jimmyjs\ReportGenerator\ServiceProvider"

如果您想生成PDF报表，请安装dompdf / snappy pdf之一。此包将自动使用snappy pdf。如果您想使用dompdf，请更改config/report-generator.php

return [
    'flush' => false,
    'pdfLibrary' => 'dompdf'
];

为了在生成PDF报表时获得更好的速度，我建议您使用laravel snappy包。要使用laravel snappy，您应该安装wkhtmltopdf以与该包一起使用（跳转到wkhtmltopdf安装）

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: store('path/to/file.pdf') to save to disk, 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外观转换为ExcelReport / CSVReport外观，无需更多修改

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';
    }
];

会产生与以下相同的结果

$columns = [
    'Name' => function($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';
    }
];

报表输出

使用此操作，您可以执行一些如下的预加载关系

$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groupBy方法之前，请先按查询对GROUP BY列进行排序。
