Exportable Behavior

This behavior implements the dosamigos\grid\contracts\RunnableBehaviorInterface of our our GridView Library. This interface allows behaviors attached to the grid to be executing code after the GridView's run() method.

Note You should really checkout the GridView Library. Its behaviors mechanism makes it the most flexible and extendable grid view widget for Yii2.

The great thing about this behavior is that it automatically checks whether there is an export post parameter with the value of 1 in order to do anything at all. That is, nothing is initialized but the behavior class if no actions are to be taken.

That is actually the reason why we created our very own exporting library, the ones that are currently in use have far too much initialization code and is really hard to actually improve without breaking stuff.

It is super simple to use and will provide your application with the amazing speed of the Spout library and its great API that will allow you to create your very own custom writers. Plus, its great memory management.

Usage

The library works with GridView Library. The following is how you configure it:

use dosamigos\exportable\ExportableButton; 
use dosamigos\exportable\behaviors\ExportableBehavior; 
use dosamigos\grid\GridView;
use dosamigos\grid\behaviors\LoadingBehavior;
use dosamigos\grid\behaviors\ToolbarBehavior;
use dosamigos\grid\buttons\ReloadButton;
use yii\helpers\Url;

echo \dosamigos\grid\GridView::widget(
    [
        'behaviors' => [
            'ExportableBehavior',
            [
                'class' => 'LoadingBehavior',
                'type' => 'bars'
            ],
            [
                'class' => 'ToolbarBehavior',
                'options' => ['style' => 'margin-bottom: 5px'],
                'encodeLabels' => false, // like this we will be able to display HTML on our buttons
                'buttons' => [
                    ReloadButton::widget(['options' => ['class' => 'btn-success']]),
                    '-',
                    ExportableButton::widget(
                        [
                            'label' => '<i class="glyphicon glyphicon-export"></i>',
                            'options' => ['class' => 'btn-default'],
                            'dropdown' => [
                                'options' => ['class' => 'dropdown-menu-right']
                            ]
                        ]
                    )
                ]
            ]

        ],
        'layout' => "{toolbar}\n{items}\n{pager}",

        // ...  more grid view configuration stuff here

Done... Really, that's it.

The Exportable Service

The behavior makes use of a dosamigos\exportable\services\ExportableService. You can actually create your very own by creating a class that implements dosamigos\exportable\contracts\ExportableServiceInterface and set its exportableService attribute.
