I am trying to: Membership and Directory site

In this era that all phone pictures are high definition, images could be as much as 15mb on a regular phone, so I needed to create some limitation for the uploads field.

I expected to see: I have created a page where subscribers can upload their headshot image for the directory in the company
I needed to limit the size of the image so my website does not become cumbersome. the field needed to have a limit like 1mb or file size to be no large than 2mb.
Instead, I got: high resolution picture of 15 mb for an application of a photo that needed to be only 150x150 pixels

Hello. Thank you for contacting the Toolset support.

Well - I would like to know that you want to validate the image on the backend (admin) while you try to upload image using custom field or featured image?

With Types 3.3 release we added the various usability improvements for custom field inputs with main focus on image fields. This includes better drag-and-drop functionality, uploading multiple files at once, and more. But there is no native way to validate the image but I can show you the way using which you can achieve this.

So, to validate the image while uploading, you need to use the hook: wp_handle_upload_prefilter

For example:

function func_validate_image_size( $file ) {
  $size = $file['size'];
  $size = $size / 1024;
  $type = $file['type'];
  $is_image = strpos( $type, 'image' ) !== false;
  $limit = 250;
  $limit_output = '250kb';
  if ( $is_image && $size > $limit ) {
    $file['error'] = 'Image files must be smaller than ' . $limit_output;
  }//end if
  return $file;
}//end nelio_max_image_size()
add_filter( 'wp_handle_upload_prefilter', 'func_validate_image_size' );

Where:
- Please feel free to adjust the code as required with your custom validation logic.
