acf/validate_value

I’ve read the documentation concerning doing a custom validation on an acf_form: http://www.advancedcustomfields.com/resources/acf-validate_value/.

I put below code in my functions.php and added and ACF image field called “validate_this_image” to my ACF front-end form.

When I submit the form with an image smaller than 960px, not any validation is happening? No error? It just submits and adds the values in WP. Do I miss something?

add_filter('acf/validate_value/name=validate_this_image', 'my_acf_validate_value', 10, 4);

function my_acf_validate_value( $valid, $value, $field, $input ){
	
	// bail early if value is already invalid
	if( !$valid ) {
		
		return $valid;
		
	}
	
	
	// load image data
	$data = wp_get_attachment_image_src( $value, 'full' );
	$width = $data[1];
	$height = $data[2];
	
	if( $width < 960 ) {
		
		$valid = 'Image must be at least 960px wide';
		
	}
	
	
	// return
	return $valid;
	
	
}

UP
I have exactly the same problem :

add_filter('acf/validate_value', 'My_validate_annonce', 10, 4 );
function My_validate_dates_annonce( $valid, $value, $field, $input ){
  if( 1 )
    return 'erreur !';
}

That do nothing…

It the same if I put this code :

add_filter('acf/validate_value/name=my_date_debut_annonce', 'My_validate_annonce', 10, 4 );
function My_validate_dates_annonce( $valid, $value, $field, $input ){
  if( 1 )
    return 'erreur !';
}
