Custom Validation for file uploader

Hello.

I would like to switch required fields depending on the value of a radio button.

I prepare fields like this:

[radio my-data-size use_label_element default:1 "Less than 2MB" "More than 2MB"]

[file my-data filetypes:pdf limit:2mb]

[text my-data-url]

And I add the code bellow:

function wpcf7_validate_customize($result,$tags){

  foreach( $tags as $tag ){
	
    $type = $tag['type'];
    $name = $tag['name'];

    switch($type){
      case radio:
      case 'radio*':
        if($name === 'my-data-size'){
          if($_POST[$name] === 'Less than 2MB'){
            if (is_null($_POST['my-data'])) {
              $result->invalidate( 'my-data','You need to upload a file' );
            }
          } elseif($_POST[$name] === 'More than 2MB') {
            if ($_POST['my-data-url'] === "") {
              $result->invalidate( 'my-data-url','You need to note a download URL' );
            }
          }
        }
        break;
    }

  }
  return $result;
}

add_filter('wpcf7_validate', 'wpcf7_validate_customize', 11, 2);

I would like to rule as below:

– When you chose “Less than 2MB”, then “my-data” is “required”.
– When you chose “More than 2MB”, then “my-data-url” is “required”.

But
When I upload a file and submit a form, “You need to upload a file” is shown.

Could you give me some advice?
