I'm using wp_get_image_editor() to resize and save an image that is being uploaded to the Media Library.

$image = wp_get_image_editor( $newattachment_url );
    if ( ! is_wp_error( $image ) ) {
        $image->rotate( 0 );
        $image->resize( 300, 300, false );
        $image->save('resizedimage.jpg');
    }

This is working fine however it is saving to the root of WordPress. How can I instead upload this file to the media library? I want to have the orignal image and the resized image in the media library.

$newattachment_url is the URL of the orignally uploaded image.

You need the generate_filename method of the image editor class. Like this:

$filename = $img->generate_filename( 'resized', ABSPATH.'wp-content/uploads/resized-images/');
$image->save($filename);

This will save the image, renamed originalname-resized, in the resized-images directory of the upload folder. This does not mean WordPress knows it is there. That depends on the context in which you are calling wp_get_image_editor().

  • Thanks for this. I ended up using media_sideload_image() to copy the resized image in the WP root to the media library and then using PHP's unlink() to remove the resized image in the root. – Josh Jun 10 '16 at 2:03
