Laravel 调用未定义的函数 Intervention\\Image\\Gd\\imagecreatefrompng()

Question

Hi I am using glide ( http://glide.thephpleague.com/ ) for image manipulation in my laravel project. I am facing an issue when storing an Image. "Call to undefined function Intervention\\Image\\Gd\\imagecreatefrompng() "

The strange thing is that I can open the image with "preview" on my mac. But not in the browser. Also Photoshop tells me that there is something wrong with this file, it's corrupt.

this is how I save the image in a private folder:

public function update(Request $request, $id)
{

  //Show the image
  echo '<img src="'.$_POST['img_val'].'" />';

  //Get the base-64 string from data
  $filteredData=substr($_POST['img_val'], strpos($_POST['img_val'], ",")+1);

  //Decode the string
  $unencodedData=base64_decode($filteredData);

  //Save the image
  $storagepath = storage_path('app/images/users/' . Auth::user()->id);
  $imgoutput = File::put($storagepath.'/flyer.jpg', $unencodedData);

  return view('backend.flyers.index')->withImgoutput($imgoutput);
                                     //->withStoragepath($storagepath);

}

It seems like File::put(XXX. jpg ) JPG causes the problem. How can I fix this?

Answer 1

This is because the GD Library is missing. Try this:

You must enable the library GD2.

Find your (proper) php.ini file

Find the line: ;extension=php_gd2.dll and remove the semicolon in the front.

The line should look like this:

extension=php_gd2.dll

Then restart apache and you should be good to go.
