Changing Category Permissions via API

Product Support

OK, this will likely be due to array handling for parameters in PHP:

Change the function to:

function editCategoryPermissions( $categoryId, $permissions, $username = 'system' ) {
  $params = array();
  foreach ( $permissions as $group => $permission ) {
    $params['permissions[' . $group . ']'] = $permission;
  }

  if ( empty( $params ) ) {
    // @todo consider throwing an exception here
    // sending empty parameters is most likely bad
  }
  return $this->_putRequest( '/categories/' . $categoryId, $params, $username );
}

And call as you did before:

$r = $api->editCategoryPermissions( 641, array( 'admins' => 1 ) );
