I have followed step by step the installation according to the web docs for intervention:
1) First I installed the latest version
$ php composer.phar require intervention/image
I have even repeated that step several times and I get the usual:
loading composer repositories, updating dependencies, nothing to install or update
2) Then I went to composer json and added this to providers
'Intervention\Image\ImageServiceProvider'
and this to facades
'Image' => 'Intervention\Image\Facades\Image'
then I repeated composer update
I also did composer dump auto-load
and nothing. Whenever I try to used it on my docs it will tell me Class Intervention not found if I specifically use it like
Intervention::make('images/' . $filename . '.' . $extension);
If I do it otherwise like
$here = $image->move(public_path().'/img/gallery', $name); //to get the source of the uploaded file
Image::make($herei->resize('200','200')->save($name));
then it will tell me that it doesn't know what "resize" is, so, not a clue of Intervention.
I am flummoxed, been trying for 8 hours non-stop. Yes, I know there is a similar question here but the solution they provide is nothing new to what I have already done.
There's no Intervention class. All calls are made to Image.
$image = Image::make('images/' . $filename . '.' . $extension);
Your second example doesn't work because you have to make an intervention image object before using resize()
Image::make($here)->resize('200', '200')->save($name);
