thinkphp實現對兩個字段或or條件搜索

thinkphp實現對兩個字段或or條件搜索

		$m=D('Adstext');
		$data['adstext_title']=array('like',"%{$keyword}%");
		$data['id']=array('like',"%{$keyword}%");
		$data['_logic'] = 'or';  //條件或
		$arr=$m->where($data)->relation(true)->select();
// 		dump($arr);
// 		exit;

Adstext是數據庫表，$data['_logic'] = 'or';  是條件或的實現
