include( "../editor/php/DataTables.php" );

use
DataTables\Editor,
DataTables\Editor\Field,
DataTables\Editor\Format,
DataTables\Editor\Mjoin,
DataTables\Editor\Upload,
DataTables\Editor\Validate;

// Build our Editor instance and process the data coming from _POST
$editor=Editor::inst( $db, 'userdetails','user_id' )
->fields(
Field::inst( 'firstname' )->validator( 'Validate::notEmpty' ),
Field::inst( 'lastname' )->validator( 'Validate::notEmpty' ),
Field::inst( 'email' )->validator( 'Validate::notEmpty' ),
Field::inst( 'company_name' )->validator( 'Validate::notEmpty' ),

);

/* need to select rows where rolenum or stype is null*/

    $editor->where( function ( $q ) {
        $q
        ->where( 'role_name', null )
        ->or_where( function ( $r ) {
            $r->where( 'stype', null  );

        } );
    } );

$editor ->process( $_POST );
