Gridview Custom Pagination

Hi,

I want custom pagination on CGridview. I want pagination dropdown on index.php view so that whenever I change value from dropdown, then grid pagination change

Index.php

<div class="country-index">

<select><option value="10">10</option>

<option value="20">20</option>

<option value="30">30</option>

</select>

    <h1><?= Html::encode($this->title) ?></h1>

    <?php //echo $this->render('_search', ['model' => $searchModel]); ?>


    <p>

        <?= Html::a('Create Country', ['create'], ['class' => 'btn btn-success']) ?>

    </p>


    <?= GridView::widget([

        'caption'=>'<h2>Javed</h2>',

    		'showHeader'=>true,

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

    		'options' => array('class' => 'grid-view'),

    		'tableOptions' => array('class' => 'table table-striped table-bordered'),

//     		'pager'=>'yii\widgets\LinkSorter',

    		'dataProvider' => $dataProvider,

        'filterModel' => $searchModel,

        'columns' => [

            ['class' => 'yii\grid\SerialColumn'],

            'code',

            'name',

            'population',


            ['class' => 'yii\grid\ActionColumn'],

        ],

    ]); ?>


</div>

CountrySearch.php

$dataProvider = new ActiveDataProvider([

            'query' => $query,

        		'pagination' => [

        			//'pageSize' => 2,

        			'pageSize'=> isset(Yii::$app->params['defaultPageSize']) ? Yii::$app->params['defaultPageSize'] : 5,

        		],




        ]);

Then you have to create your own pager widget class (either standalone or extending \yii\widgets\LinkPager) and configure GridView like:

<?= GridView::widget([

        ...

        'pager' => [

            'class' => 'my\custom\Pager',

            //other pager config if nesessary

        ],

        ...

LinkSorter is not suitable for pagination, it is used in the same way as sort links in GridView table header.

I have made following changes, but I still can’t find filter widget:

<?= GridView::widget([

        

    		'showHeader'=>true,

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

    		'options' => array('class' => 'grid-view'),

    		'tableOptions' => array('class' => 'table table-striped table-bordered'),

//     		'pager'=>'yii\widgets\LinkSorter',

    		'dataProvider' => $dataProvider,

       		 'filterModel' => $searchModel,

    		'pager' => [

    			'class' => '\yii\widgets\LinkPager',

    		//other pager config if nesessary

    		]...

?

You’ve told you need pager widget, not filter.

As for dropdown pager - I made quick draft of it, you may try it:

Code here

Put it in frontend/widgets directory - if you use advanced app.

In Gridview:

        ...

        'pager'        => [

            'class' => 'frontend\widgets\DropdownPager',

        ],

        ...

If your app structure differs from advanced app - choose destination folder and change namespace according to your structure.

Thanks for support. Well I am using basic APP not advance. So in basic app where I should add DropdownPager.php file.

Even I have created following directory but it still I get error (Class ‘frontend\widgets\DropdownPager’ not found)

frontend\widgets\

Well, you can create for example widgets folder and change namespace in file:

namespace app\widgets;

and in GridView respectively:

        ...

        'pager'        => [

            'class' => 'app\widgets\DropdownPager',

        ],

        ...

Modified a bit current page display (line 29 and line 69)

I still get this error:

Unable to find ‘app\widgets\DropdownPager’ in file: /home/javed/workspace/mfc/widgets/DropdownPager.php. Namespace missing?

MODEL:CountrySearch.php

Why did you put in your model CountrySearch.php second namespace:

...

namespace app\models;

namespace app\widgets;

...

Leave one namespace in model

...

namespace app\models;

...

Modify namespace in widget (file DropdownPager.php):

instead of

...

namespace frontend\widgets;

...

you should put

...

namespace app\widgets;

Now i can see per page records link at the end of gridview but I can’t change.

It’s working for me.

Check if there are javascript errors on the page. Check the order in which scripts are loading.

Ok I will check. Thanks for helping sergeD. Really appreciate
