ImagePreviewer on Windows

[juppwerner]

Hi,
thanks for this great Yii2 extension!

I am testing this on my Windows dev PC.
The preview for image files in the form view does not work.

Here is my fix to the function prepareFolder in the file sc/logic/ImagePreviewer.php:

protected function prepareFolder()
{
    // Windows: remove a double backslash:
    $this->fileName = str_replace("\\\\", "\\", $this->fileName);
    // Windows: convert backslash to forward slash, works too:
    $this->fileName = str_replace("\\", "/", $this->fileName);
    if (!file_exists(Yii::$app->getModule('files')->cacheFullPath))
        mkdir(Yii::$app->getModule('files')->cacheFullPath);
    $lastFolder = '/';
    // Windows: don't start with slash, first part is drive letter w/o slash
    if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN')
        $lastFolder = '';
    $explodes = explode('/', $this->fileName);
    array_pop($explodes);
    if (empty($explodes))
        return;
    foreach ($explodes as $folder) {
        if (empty($folder))
            continue;
        $lastFolder = $lastFolder . $folder . '/';
        if (!file_exists($lastFolder))
            mkdir($lastFolder);
    }
}

Thanks for adding this.

Regards
Joachim

Hello!
Thank you.

I can not say anything about the work of my module on the window. PHP applications in production are always run on Unix machines, and therefore they must be developed in a similar environment. I always use docker for development, and forgot about these problems forever. I highly recommend using it too

If you want to make changes to the code, make a pull request and if everything works, I will update the library. No problem at all.
