Allows for large data set exports from a GridField. By using an asynchronous job queue, we avoid running out of PHP memory or exceeding any maximum execution time limits.

The exact limitations of a standard GridField export vary based on the server configuration, server capacity and the complexity of the exported DataObject. As a rough guide, you should consider using this module when more than 1000 records need to be exported. The module should be able to export 10,000 records on a standard server configuration within a few minutes.

• SilverStripe 4.0+
• The queuedjobs module

Note: For SilverStripe 3.x, please use the 1.x release line.

To install run composer require silverstripe/gridfieldqueuedexport.

Since this component operates on a GridField, you can simply use it's addComponent() API.

$gridField = new GridField('Pages', 'All pages', SiteTree::get())
$config = $gridField->getConfig();
$config->addComponent(new GridFieldQueuedExportButton('buttons-after-left'));

If you want to replace the GridFieldExportButton created by the default GridField configuration, you also need to call removeComponentsByType().

// Find GridField
$gridField = $fields->fieldByName('MyGridField');
$config = $gridField->getConfig();

// Add new component
$oldExportButton = $config->getComponentByType('GridFieldExportButton');
$config->addComponent($newExportButton = new GridFieldQueuedExportButton('buttons-after-left'));

// Set Header and Export columns on new Export Button
$newExportButton->setCsvHasHeader($oldExportButton->getCsvHasHeader()); 
$newExportButton->setExportColumns($oldExportButton->getExportColumns());

// Remove original component
$config->removeComponentsByType('GridFieldExportButton');

Note: This module is preconfigured to work with the silverstripe/userforms submission CSV export.
