Save Post and populate field with image

  This is not an issue.

  But I am not knowing how to develop my idea with ACF.
  I know that I have to use acf_save and wp_image_editor to achieve this though.

  wp_image_editor is documented and so of course by WP.

  I got two fields for image-object, with the names of:
  ‘img-standing’
  ‘img-horizontal’

  I want only for the user logged in to upload a standing wine-bottle into the ‘img-standing’. And the horizontal image should be done automatically through the wp-image-editor and then set to the ACF-field ‘img-horizontal’.

  I could also use CSS to make rotation, but I dont want to go that way as it is for now in this application. I rather rely on the images being accessible as files.

  Thanks for any input.

  Hi @hejamartin,

  Thanks for the post.

  I would recommend you make use of the PHP function imagerotate() to rotate the image and then save back the rotated image as a new file.

  The code would look like so:

  //define image path
  $filename="image.jpg";
  
  // Load the image
  $source = imagecreatefromjpeg($filename);
  
  // Rotate
  $rotate = imagerotate($source, $degrees, 0);
  
  //and save it on your server...
  file_put_contents("myNEWimage.jpg",$rotate);

  For loading the newly created image, you can make use of the acf/load_field filter after storing the image object in a $variable.
