$User = M("User"); //实例化User对象$condition['name'] = 'thinkphp'; // 把查询条件传入查询方法 $User->where($condition)->select();
$User = M("User"); // 实例化User对象 // 定义查询条件 $condition = new stdClass(); $condition->name = 'thinkphp'; // 查询name的值为thinkphp的记录 $User->where($condition)->select(); // 上面的查询条件等同于 where('name="thinkphp"') 使用对象方式查询和使用数组查询的效果是相同的,并且是可
带where条件的普通查询
1、字符串形式
$user=M('user'); $list=$user->where('id>5 and id<9')->select(); $list=$user->where($data)->select();
$user=M('user'); $list=$user->where(array('username'=>'www.jb51.net'))->select(); $list=$user->where($data)->select();
$user=M('user'); $a=new stdClass(); $a->username='www.jb51.net; $list=$user->where($a)->select();
$M_shopping = M('Shops'); $M_product = M('Product'); $list_shops = $M_shopping->join('as shops left join hr_product as product on shops.product_id = product.p_id') ->field('product.p_id,product.p_name,shops.product_amount,shops.product_id') ->where("shops.user_cookie='".$_COOKIE['hr_think_userid']."'") ->group('shops.id') ->select();
区间查询
$user=M('user'); $data['id']=array(array('gt',20),array('lt',23),'and'); $list=$user->where($data)->select();
$user=M('user'); $data['username']='pengyanjie'; $data['password']=array('eq','pengyanjie'); $data['id']=array('lt',30); $data['_logic']='or'; $list=$user->where($data)->select(); dump($list);
$user=M('user'); $data['username']=array('eq','pengyanjie'); $data['password']=array('like','p%'); $data['_logic']='or'; $where['_complex']=$where; $where['id']=array('lt',30); $list=$user->where($data)->select();
$M_shopping = M('Shops'); $M_product = M('Product'); $M_proimg = M('Product_image'); $list_shops = $M_shopping->join('as shops left join hr_product as product on shops.product_id = product.p_id left join hr_product_image as productimgon productimg.p_id = product.p_id')->fiel('productimg.pi_url,product.p_id,product.p_name,shops.product_amount,shops.product_id,product.am_id, product.p_procolor,product.p_price,product_amount*p_price as totalone')->where("shops.user_cookie='".$_COOKIE['hr_think_userid']."'") ->group('shops.id')->select();
$m_test = M("Product"); $productmeaage = $m_test->where("p_id='$proid'")->select();
② 除了上面的方法还有一种是以数组的方式
$M_product = M('Product'); $map['pid'] = $proid; $p_result = $M_product->where($map)->select();
