Unable to pass class instance to constructor - php

Question

I have installed this package https://github.com/Intervention/image with composer. I have added
'IntImage' => 'Intervention\Image\Facades\Image'
to config/app under aliases
I get the following error and cant figure out what I am doing incorrectly I am sure it has something to do with namespacing /autoloading but app/acme is in the psr-o section of composer.json
'Argument 1 passed to
Acme\Services\Images\InterventionImageEditor::__construct() must be an
instance of IntImage, none given, called in
/var/www/app/ACme/Providers/ImageEditorServiceProvider.php on line 14
and defined' in
/var/www/app/Acme/Services/Images/InterventionImageEditor.php:11
I have the following directory structure
app
acme
Providers
ImageEditorServiceProvider.php
Services
Images
ImageEditorInterface.php
InterventionImageEditor.php
and the content of the files
ImageEditorServiceProvider.php
<?php namespace Acme\Providers;
use Illuminate\Support\ServiceProvider;
use Acme\Services\Images\InterventionImageEditor;
/**
*
*/
class ImageEditorServiceProvider extends ServiceProvider
{
public function register()
{
$this->app->bind('Acme\Services\Images\ImageEditorInterface', function () {
return new InterventionImageEditor();
});
}
}
ImageEditorInterface.php
<?php namespace Acme\Services\Images;
interface ImageEditorInterface
{
public function hello();
}
InterventionImageEditor.php
<?php namespace Acme\Services\Images;
use IntImage;
/**
*
*/
class InterventionImageEditor implements ImageEditorInterface
{
protected $imageeditor;
public function __construct(IntImage $imageeditor)
{
$this->imageeditor = $imageeditor;
}
public function hello()
{
$hello = 'hello';
return $hello;
}
}
Can I
Use IntImage;
in this way because it is a facade or am I missing something?
edit to include solution;
changing the service provider to the following resolved the problem
<?php namespace Acme\Providers;
use Illuminate\Support\ServiceProvider;
use Acme\Services\Images\InterventionImageEditor;
use IntImage;
/**
*
*/
class ImageEditorServiceProvider extends ServiceProvider
{
public function register()
{
$this->app->bind('Acme\Services\Images\ImageEditorInterface', function () {
$intimage = new IntImage;
return new InterventionImageEditor($intimage);
});
}
}

Answer 1

The error is coming from ImageEditorServiceProder.php:
$this->app->bind('Acme\Services\Images\ImageEditorInterface', function () {
return new InterventionImageEditor();
});
Here you are instantiating the InterventionImageEditor without any parameters. You InterventionImageEditor requires one parameter of type IntImage.
If there are places where you won't have IntImage when instantiating InterventionImageEditor then you need to update your InterventionImageEditor::__construct so that it accepts null(possibly).
function __construct(IntImage $imageeditor = null)
{
if (is_null($imageeditor)) {
// Construct a default imageeditor
// $imageeditor = new ...;
}
$this->imageeditor = $imageeditor;
}

i am not sure you can using IntImage because this file is Facades.
if you want to extending the intervention class. you should add Intervention\Image\Image to your ImageEditorServiceProvider.
use Intervention\Image\Image;
class ImageEditorServiceProvider extends ServiceProvider
{
public function register()
{
$this->app->bind('Acme\Services\Images\ImageEditorInterface', function () {
return new InterventionImageEditor(new Image);
});
}
}
