How i do custom Yii2 gridview sort? - php

Question

How can I sort with a customized gridview header?
Please give the difference between label and header in the Yii2 gridview widget dataprovider.
Here is my code:
<?= GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
[
'class' => 'yii\grid\DataColumn',
'value' => function ($data) {
return $data->myTitle;
},
'headerOptions' => ['style'=>'text-align:center'],
'header' => 'Page Title',
'label' => 'Title'
],
]); ?>
Do header and label perform the same function?
How can I perform sorting in $data->myTitle?
Here my Output Screen:
I want Page Title, Status, Date Modified should be active.
Thanks in advance.

Answer 1

Found the answer.
Please add attributes to ActiveDataProvider in your Search Model.
$dataProvider = new ActiveDataProvider([
'query' => $query,
'pagination' => [
'pageSize' => 5,
],
'sort' => ['attributes' => ['myTitle']],
]);
Add the attribute option in widget:
<?= GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
[
'class' => 'yii\grid\DataColumn',
'value' => function ($data) {
return $data->myTitle;
},
'headerOptions' => ['style'=>'text-align:center'],
'attribute' => 'myTitle',
'label' => 'Page Title'
],
]); ?>

Answer 2

Since myTitle is a field from the database and not a custom value, you can just use attribute. The rest may be unnecessary e.g the default class is DataColumn
'columns' => [
[
'attribute' => 'myTitle',
'label' => 'Label',
]

Answer 3

I am not very sure I understand your question, but sorting option can be included in your modelsearch.php. So in your case you have to do like this.
$dataProvider = new ActiveDataProvider([
'query' => $query,
'sort'=> ['defaultOrder' => ['your_column'=>SORT_ASC]]
]);
if myTitle is a field in the database, why you are using such a long syntax. Just
'Columns'=>[
..
'myTitle',
..
],
should work fine and should be active for sorting as you want
if you want a different header/label for the column, use label instead of header as header is only a cell content and cannot be used for sorting, while label can. details
[
..
'attribute'=>'myTitle',
'label' => 'Page Title'
..
],
