Sort mixed models with one dataprovider using ArrayDataProvider - php

Question

I used ArrayDataProvider to mix models and then merged them into one data-provider. I used the data-provider in grid-view and everything is works fine.
But I need to order the grid-view by one column I tried a lot of solutions but none of them are worked.
This my model code (order by item_order )
public function getAllSelectedItemsInTheUnit($unitId, $grid = false)
{
$finalList = array();
$storiesList = array();
$activityList = array();
$breakList = array();
$stories = UnitStories::find()->joinWith(['story'])->where("unit_id=$unitId")->all();
if (count($stories) > 0) {
foreach ($stories as $item) {
$storiesList[] = [
'key' => self::TYPE_STORY . $item->id,
'id' => $item->id,
'title' => $item->story->title,
'type' => self::TYPE_STORY,
'item_order' => $item->unit_order,
];
}
}
$activities = UnitActivities::find()->joinWith(['activity'])->where("unit_id=$unitId")->all();
if (count($activities) > 0) {
foreach ($activities as $item) {
$activityList[] = [
'key' => self::TYPE_ACTIVITY . $item->id,
'id' => $item->id,
'title' => $item->activity->title,
'type' => self::TYPE_ACTIVITY,
'item_order' => $item->activity_order,
];
}
}
$breaks = UnitBreaks::find()->where("unit_id=$unitId")->all();
if (count($breaks) > 0) {
foreach ($breaks as $item) {
$breakList[] = [
'key' => self::TYPE_BREAK . $item->id,
'id' => $item->id,
'title' => $item->title,
'type' => self::TYPE_BREAK,
'item_order' => $item->unit_order,
];
}
}
$finalList = array_merge($storiesList, $activityList, $breakList);
$dataProvider = new ArrayDataProvider([
'allModels' => $finalList, 'key' => 'key',
'sort' => [
'attributes' => ['item_order'],
],
]);
return $dataProvider;
}
Any solution will be very good even sort array by pure PHP I guess will fix the problem .

Answer 1

You can use usort()
usort($finalList, function ($a, $b) {
return $a['item_order'] < $b['item_order'];
});
Add your condition in callback >, <, <= etc
