Question

I’m using symfony to develop a website and have it mostly functioning, but I need it to resize images to a certain size when they are uploaded. I installed the sfImageTransfomPlugin to allow me to resize them, and figured out that I need to overload the save() method in the model class, but I can’t find any documentation to get the information about the uploaded image so that I can resize it. Has anyone done this before or can point me to some documentation for it?

Thanks in advance.

Resizing images in model is not a good practice, imho.

The plugin’s documentation already tells about simple implementation:

public function executeUpload($sfWebRequest) {
    [...]
    $img = new sfImage($filename, 'image/jpg');
    $img->resize(100, 100);
    $img->save();
    [...]
}

Assuming you bind submitted values via bind method:

$this->form->bind(...);

Name of uploaded file you can get from your form object:

$file = $this->form->getValue('file');
$filename = $file->getOriginalName().$file->getExtension($file->getOriginalExtension());
