A module for exporting any contao entity to file.

Export config preview

Features

• export entities and list of entities
• easily add backend modules to your application/extension or use the frontendmodule
• expandable exporter architecture
• included exporter:
  • csv
  • Excel (xlsx)
  • pdf
  • Media files (export media files assoziated with an entity as archive(zip))

Csv and Excel export are archived by Spout library. PDF export is archived by mPDF library. This library comes not as dependency and therefore must be added to your bundle/project dependencies to archvie pdf export functionality.

Technical instruction

Install

Install with composer:

composer require heimrichhannot/contao-exporter-bundle

If you want to use the pdf exporter, add "mpdf/mpdf":"^7.0" to your composer dependencies.

Backend export

Step 1

Define your global operation in your entity's dca as follows:

'global_operations' => [
    'export_csv' => \Contao\System::getContainer()->get('huh.exporter.action.backendexport')
        ->getGlobalOperation('export_csv',$GLOBALS['TL_LANG']['MSC']['export_csv'])
],

Step 2

Add your backend module in your entity's config.php as follows:

$GLOBALS['BE_MOD']['mygroup']['name'] = [
    'export_csv' => ['huh.exporter.action.backendexport', 'export'],
    'tables' => ['tl_name'],
];

Step 3

Create a configuration for your export by using the exporter's backend module (group devtools).

Frontend

You can use the included frontend module to add an easy export functionality.

You can also use frontendedit or formhybrid_list in order to easily create a module for manipulating your entities in the frontend. It already contains a function to export entities after submission!

You can also create an custom implementation for your extension:

1. Create a configuration for your export by using the exporter's backend module (group devtools).
2. Call export() of huh.exporter.action.frontendexport service in your module:

/** @var Symfony\Component\DependencyInjection\ContainerInterface $container */
$container->get('huh.exporter.action.export')->export($config: ExporterModel, $entity: int|string, $fields = []: array);

Developers

Upgrade from exporter module

Please see Upgrade Instructions.

Events

You can hook into the export with given event. Please check Symfony Event Documentation if you don't know how.

Add custom exporter

You can add custom exporter to add additional file types or functionality.

Your exporter class must implement ExporterInterface and must be registered in the container with the huh_exporter.exporter service tag. We recommend to extend AbstractExporter, because it already has most of the mechanics implemented.

services:
  _defaults:
    autowire: true

  _instanceof:
    HeimrichHannot\ContaoExporterBundle\Exporter\ExporterInterface:
      tags: ['huh_exporter.exporter']
      lazy: true
      
  Your\Exporter\Class: ~

Custom field selection

You can pass an array of fields to export() of an exporter. Those fields will be used, when exporting an item.

There are two options:

1. A list of field names. Example: ['firstname','lastname','age']
2. A field list with labels and values. Should be structured as shown:

<?php 
$fields = [
    'field1' => [
        'raw' => '', // raw field value
        'inputType' => '', // field input type 
        'value' => '', // formatted field value
        'formatted' => '', // formatted field value
        'label' => '', // formatted field value
    ],
    // ...
];

Pdf

To use Pdf export, you first need to install mPDF.

Templates

You can overwrite the pdf output template. Templates are written in Twig and name should start with exporter_pdf_. See exporter_pdf_item_default.html.twig for a working example.

Fonts

To add custom Pdf font, please see the corresponding chapters in Utils Bundle docs and the mPDF Docs. Afterwards you can add the folders in the exporter config.
