Question

Yii

My class for working with images:

And its use:

After that everything is fine

But as soon as I write to save the image in a certain directory

, the following error pops up

even if I change and put a slash before uploads

$file->saveAs(Yii::getAlias('@web').'/uploads/'.$file->name);

Nothing will change. I am using MAMP server and macOS. Maybe that's why he can't find it? If yes, how to fix it?

Answer 1

@webroot points to the root of the application, you need to use it:

$file->saveAs(Yii::getAlias('@webroot').'/uploads/'.$file->name);

Answer 2

Is the image saved?
Try this:
alias
preservation
Also check the write permissions to the directory.
