Yii2: Access model value in view - php

Question

I have a variable status declared in model. Status is a column in gridview that is populated using this:
[
'attribute' => 'status',
'contentOptions' => ['class' => 'text-center'],
'value' => function($model){
if($model->nginSum != $model->sapValue){
return 'NOK';
} else {
return 'OK';
}
},
],
I want to count the number os OKs and NOKs to display equal and diferent entries with a counter.
I've tried declaring a function in search model:
public function getStatus()
{
return $this->status;
}
and in view i did this:
$equal = 0;
$different = 0;
$stat = new EtuLojaSearch;
if ($stat->getStatus() == 'OK') {
$equal += 1;
} else {
$different += 1;
}
but it's returning null.
What am i doing wrong?
Edited:
function in model:
public function getStatus()
{
if($this->nginSum != $this->sapValue){
return 'NOK';
} else {
return 'OK';
}
}
In view:
$iguais = 0;
$diferentes = 0;
$stat = new EtuLojaSearch;
if ($stat->status == 'OK') {
$iguais += 1;
} else {
$diferentes += 1;
}
Edit 2:
Status is ot getting bound to model using getStatus() function.

Answer 1

Update your getStatus method with following.
public function getStatus()
{
if($this->nginSum != $this->sapValue){
return 'NOK';
} else {
return 'OK';
}
}
It will bind value (OK, NOK) with status attribute when active record is fetched and later on you can use that value in whatever way you wish eg $model->status. With this approach, your attribute rendering code will be like following.
[
'attribute' => 'status',
'contentOptions' => ['class' => 'text-center'],
'value' => function($model){
return $model->status;
},
],
But to count different values for status, you'll have to loop through all models i-e
$equal = 0;
$different = 0;
foreach($dataProvider->getModels() as $item){
if ($item->status == 'OK') {
$equal += 1;
} else {
$different += 1;
}
}
