Trying to use a barcode library with Composer and CI4

Hi

I could successfuly install (in a CI4 install in subfolder) the following libraries with Composer: dompdf and guzzlehttp
Then, I use both in the Controller, etc.

Code:

...
...
use Dompdf\Dompdf;
use GuzzleHttp\Client;
...
...
$client = new \GuzzleHttp\Client(['http_errors' => false]);
$dompdf = new Dompdf();
...
...

But I cannot make the same with the following one:

https://github.com/picqer/php-barcode-generator

I've installed with this

Code:

composer require picqer/php-barcode-generator

Then I use with

Code:

use Picqer\Barcode;
use Picqer\Barcode\BarcodeGeneratorPNG;

But when I try to use it, CodeIgniter does not find it

Code:

$generator = new Picqer\Barcode\BarcodeGeneratorPNG();

Class 'App\Controllers\Picqer\Barcode\BarcodeGeneratorPNG' not found

I've checked the "vendor/composer/autoload_psr4.php" file to see the namespaces.

Any suggestions ?

Thanks a lot

its also use Exceptions.

So you would also have to load the Exceptions before the other two classes.

It's also using Imagick for drawing the barcodes.

Where did you notice/find that? and how do you know that the Exception classes should be load before the others?

Thanks again

If you use "use" you can do:

use Picqer\Barcode\BarcodeGeneratorPNG;

$generator = new BarcodeGeneratorPNG();

or


use Picqer\Barcode\BarcodeGeneratorPNG as AnOtherName;

$generator = new AnOtherName();

If you use "use" you can do:

use Picqer\Barcode\BarcodeGeneratorPNG;
$generator = new BarcodeGeneratorPNG();

or

use Picqer\Barcode\BarcodeGeneratorPNG as AnOtherName;
$generator = new AnOtherName();

Great! that worked fine. Thanks again for the useful tips

If you look at the barcode class files you will see what they are loading.
