I have working code for saving image until I decided to add a resize function. I have already done the following:

composer require intervention/image

added this on $providers

Intervention\Image\ImageServiceProvider::class

and this on $aliases

'Image' => Intervention\Image\Facades\Image::class

on my controller I add this

use Intervention\Image\ImageManagerStatic as Image;

but actually I don't know where to put the resize ( "resize(900, 900);" ) so I have this,

public function update_avatar(Request $request){

    $request->validate([
        'avatar' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2012',
    ]);

    $user = Auth::User();

    if($user->avatar !== 'user.jpg'){
      $folder = 'avatars';
      Storage::delete($folder.'/'.$user->avatar);
    }

    $avatarName = $user->id.'_avatar'.'.'.request()->avatar->getClientOriginalExtension();
    $request->avatar->resize(900, 900);
    $request->avatar->storeAs('avatars',$avatarName);

    $user->avatar = $avatarName;
    $user->save();

    return back()
        ->with('success','You have successfully upload image.');
}

and here's the error

can anyone help me to figure this out? Thank you so much in advance.

SOLUTION base from @Snapey

    $canvas = Image::canvas(900, 900);

    $image = Image::make($request->avatar);
    $image->resize(900,900,
        function($constraint)
            {
                $constraint->aspectRatio();
            });
    
    $canvas->insert($image, 'center');       
    $path = Storage::path('avatars');
    $canvas->save($path . '/' . $avatarName);

I added a canvas so that the photo will remain proportional instead of look stretched image.

CodePudding user response：

You need to create an Intervention Image object from the uploaded file, then resize and save it

    $avatarName = $user->id.'_avatar'.'.'.request()->avatar->getClientOriginalExtension();

    $image = Image::make($request->avatar);
    $image->resize(900, 900);
    $path = Storage::disk('avatars')->path();
    $image->save($path . '/' . $avatarName);
