How to call variables and functions from an external library in Yii2?

Question

I call to an external library in a fileForm in the models layer

namespace app\models;
use Yii;
use yii\base\Model;
include "../lib/libchart/classes/libchart.php"; //external library

However Yii2 does not recognize a variable from that external library, the error is: "PHP Fatal Error – yii\base\ErrorException - Class 'app\models\LineChart' not found"

I have the following function in the fileForm:

public function insertGrafic() { $chart = new LineChart(); ... }

What's missing? Thanks.

Hope it helps stackoverflow.com/questions/28128117/…

Just try to add the library as a Component in your config file.

Write & use a custom Component in Yii2.0

'components' => [
    'libchart' => [
        'class' => 'class Path',
    ],

Then use your component method like this:

Yii::$app->libchart->method();

I added the former 'components' statement in config\web.php and in config\console.php ('libchart' => [ 'class' => 'lib\libchart\classes\libchart.php', ], ) And I get this message: "Class lib\libchart\classes\libchart.php does not exist" What is wrong? Thanks.

Check if the library extends the interface Component of Yii and has a valid namespace. If not, add it, it should not change how library works.

How do I add the all third-party and create its namespace? Thanks

copy it in your project folder, you can create a special foler base/libchart for example. Then open the class file and add the namespace namespace app\libchart. Use the guide i've post to do it properly.

I apreciate your help. I am getting something wrong in the logic (I get this error: Namespace missing?). I created a folder base/libchart. Then I created a file libchart.php with class libchart extends Component {public function welcome()... Then at the model's layer I call public function insert(){Yii::$app->libchart->welcome();....}

yii2 is fully namespaced. instead of using includes you have to use namespace. based on the error message it looks the external library has a namespace as a result you can try as below

use app\models\LineChart;

remove the include and try

You mean its not necessary to set the path where the external library is located in the project? Thanks.

I have solved the issue by using another wraper (https://github.com/miloschuman/yii2-highcharts). (1) I put the following lines in the require section of the composer.json file: "yiisoft/yii2-jui": "*", "miloschuman/yii2-highcharts-widget": "dev-master" (2) And then run in the console the command: composer update
