Yii 2 - Class 'CArrayDataProvider' not found - php

Question

I'm new at yii and trying to find my way around. I have done a tutorial or two. I then decided to start editing/changing the example to allow me to learn more. I created a page that does a simple PING. That gets validated. On success, it loads a static page. This all works.
What I wanted to do next is to see how I can utilize a grid to populate that with some data. My real life example is the same. I will get a array of data coming in.
It seems that CArrayDataProvider is what I need. So, I am trying to get a very simple example to work. If I get this to work, I can move on.
I have tried a whole bunch of examples. The error is the same every time. It seems that I do not have CArrayDataProvider installed? If that is even possible.
I did a standard basic install:
composer create-project --prefer-dist yiisoft/yii2-app-basic basic
I have the following at the beginning of my controllers file:
use yii2\data\ArrayDataProvider;
I get no error here.
I searched for the file itself on the file system, could not find it. I did find ArrayDataProvider, so I tried that, same result:
use vendor\yiisoft\yii2\data\ArrayDataProvider;
The error is:
PHP Fatal Error – yii\base\ErrorException
Class 'CArrayDataProvider' not found
This is on line 24:
"dataProvider = new CArrayDataProvider($fruits);"
Here is my example code. Not that I think the issue is in here, but to show what I am trying to do:
$fruits = array(
array('id' => 1, 'name'=>'apple', 'color' => 'green'),
array('id' => 2, 'name'=>'orange', 'color' => 'orange'),
array('id' => 3, 'name'=>'banana', 'color' => 'yellow'),
array('id' => 4, 'name'=>'pineapple', 'color' => 'brown')
);
$dataProvider = new CArrayDataProvider($fruits);
$this->widget('zii.widgets.grid.CGridView', array(
'id' => 'fruits-grid',
'dataProvider' => $dataProvider ,
'columns' => array(
array(
'name' => 'ID',
'value' => '$data["id"]',
),
array(
'name' => 'Name',
'value' => '$data["name"]'
),
array(
'name' => 'Color',
'value' => '$data["color"]'
),
)
));
On the file-system (linux) itself I did a update:
composer update
I have been Googling for the last 2 days and I am finding nothing.
I tried adding a date picket. That worked. I used:
https://www.tutorialspoint.com/yii/yii_extensions.htm
So in short, the static page that I call, now displays a DateTimePicker.
At the start of the file I added:
use kartik\datetime\DateTimePicker;
And in the body:
<?php
echo DateTimePicker::widget([
'name' => 'dp_1',
'type' => DateTimePicker::TYPE_INPUT,
'value' => '23-Feb-1982 10:10',
'pluginOptions' => [
'autoclose'=>true,
'format' => 'dd-M-yyyy hh:ii'
]
]);
?>
How do I get yii2 to allow me to use ArrayDataProvider. Or how do I install the extension? Or who do I reference it?

Answer 1

In Yii2 there's not a CArrayDataProvider. Use ArrayDataProvider, like described in docs:
$provider = new yii\data\ArrayDataProvider([
'allModels' => $query->from('post')->all(),
'sort' => [
'attributes' => ['id', 'username', 'email'],
],
'pagination' => [
'pageSize' => 10,
],
]);
Pretty well documented here.

Answer 2

Yii2 supports ArrayDataProvider and yii 1.* supports CArrayDataProvider, so as per your code you are using Yii2, so just replace the below line with
$dataProvider = new CArrayDataProvider($fruits);
With this:
$dataProvider = new ArrayDataProvider($fruits);

Thx to everyone's help! I now have a working example.
In case anyone else has the same issues, I will post my working code here:
use kartik\grid\GridView;
$resultData = [
array("id"=>1,"name"=>"Cyrus","email"=>"risus#consequatdolorvitae.org"),
array("id"=>2,"name"=>"Justin","email"=>"ac.facilisis.facilisis#at.ca"),
array("id"=>3,"name"=>"Mason","email"=>"in.cursus.et#arcuacorci.ca"),
array("id"=>4,"name"=>"Fulton","email"=>"a#faucibusorciluctus.edu"),
array("id"=>5,"name"=>"Neville","email"=>"eleifend#consequatlectus.com"),
array("id"=>6,"name"=>"Jasper","email"=>"lectus.justo#miAliquam.com"),
array("id"=>7,"name"=>"Neville","email"=>"Morbi.non.sapien#dapibusquam.org"),
array("id"=>8,"name"=>"Neville","email"=>"condimentum.eget#egestas.edu"),
array("id"=>9,"name"=>"Ronan","email"=>"orci.adipiscing#interdumligulaeu.com"),
array("id"=>10,"name"=>"Raphael","email"=>"nec.tempus#commodohendrerit.co.uk"),
];
$dataProvider = new \yii\data\ArrayDataProvider([
'key'=>'id',
'allModels' => $resultData,
'sort' => [
'attributes' => ['id', 'name', 'email'],
],
]);
echo GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'id',
[
'attribute' => 'name',
'value' => 'name',
],
[
"attribute" => "email",
'value' => 'email',
]
]
]);
