Laravel image upload validation - php

Question

I am trying to validate uploaded files using laravel validation but am having issues.
Here is my code:
$this->validate($request, [
'image' =>'mimetypes:image/jpeg,image/png,image/gif',
]);
$avatar = $request->file('image');
$fileName = time(). '.' . $avatar->getClientOriginalExtension();
Image::make($avatar)->resize(300,300)->save( public_path('uploads/avatar/' . $fileName));
$user = Auth::user();
$user->avatar = $fileName;
$user->save();
The issue is when I use a bmp file, I get this error:
Gd error
I am using the Intervention image package. I would rather not switch to the imagick driver.
Any ideas?

Answer 1

Looking at the Intervention package code, you can see two implementations to the processBmp function:
Intervention/Image/Gd/Encoder.php:
protected function processBmp()
{
throw new \Intervention\Image\Exception\NotSupportedException(
"BMP format is not supported by Gd Driver."
);
}
Intervention/Image/Imagick/Encoder.php:
protected function processBmp()
{
$format = 'bmp';
$compression = \Imagick::COMPRESSION_UNDEFINED;
$imagick = $this->image->getCore();
$imagick->setFormat($format);
$imagick->setImageFormat($format);
$imagick->setCompression($compression);
$imagick->setImageCompression($compression);
return $imagick->getImagesBlob();
}
So I think it's safe to say that you can't do it with the GD driver, only with imagick.

Answer 2

Simply use "intervention/image": "~2" or change your driver to Imagick. It is a known issue that GD does not natively support BMP. You can check the issue page on github for details.

Answer 3

Why you don`t use Laravel custom rule for image image?
$this->validate($request, [
'image' =>'image',
]);

Answer 4

hope this solution will fix your error, please try with below logic
public function postUpload(Request $request)
{
$input = $request->all();
$rules = array(
'uploadFile' => 'image|max:8000'
);
$validation = Validator::make($input, $rules);
if ($validation->fails())
{
return array(
'validation_failed' => true,
'errors' => $validation->errors()->toArray()
);
}
$file = $request->uploadFile;
$destinationPath = 'uploads/img';
// Get real extension according to mime type
$ext = $file->extension();
// Hash processed file name, including the real extension
$hashname = date('H.i.s').'-'.md5($request->_token).'.'.$ext;
$upload_success = $request->uploadFile->storeAs($destinationPath, $hashname);
Image::configure(array('driver' => 'imagick'));
$img = Image::make(storage_path() . '/app/uploads/img/' . $hashname);
$img->resize(230, null, function ($constraint) {
$constraint->aspectRatio();
});
$img->save(storage_path() . '/app/uploads/lowres/' .$hashname ,80);
$user_image = new User_images();
$user_image->id_user = Auth::user()->id;
$user_image->handler = $hashname;
$user_image->save();
return array('status' => 'success','message'=> 'Image has been uploaded successfully','file_path'=>'/uploads/'.$hashname);
