yii2 gridview hide empty column not working

Question

I want to hide yii2 gridview empty column if value is null but my code is not working.

I have tried this code:

[
 'attribute'=>'division',
 'value'=>'divisionName.name',
 'visible' => function ($data) {
  if ('divisionName.name' == NULL) {
   return '0'; // or return true;
  } else {
   return '1'; // or return false;
  }
 },
]

And then tried this:

[
 'attribute'=>'division',
 'value'=>'divisionName.name',
 'visible' => function ($data) {
  if ('divisionName.name' == NULL) {
   return  true;
  } else {
   return  false;
  }
 },
]

Above both line of codes not working.

If divisionName.name equal to null then hide entire column from gridview, what is wrong with this code?

Answer 1

Seems you have also a logical problem because you would show a null value and hide a not null value ..

The right solution is based on an check for the hide/show condition before the widget is showed

$showDivision = myFunctioForShow(...);

[
     'attribute'=>'division',
      .....
      'visible' => $showDivision ,
] ,
