kav*_*avi 9 php mysql sql arrays multidimensional-array
我有2个表:产品和购物车,我希望将这两个表组合在一起,并根据特定条件在数组中显示数据,如下所示:
应显示特定类别下的所有产品,如果特定用户在给定产品中购买了任何产品,则其详细信息也应显示在该产品的前面
我到目前为止所做的代码是
$catid = $_REQUEST['catid'];
$userid = $_REQUEST['userid'];
$sql = "select * from productsize where catid = '".$catid."' GROUP BY productid";
$result = mysqli_query($con, $sql);
if (mysqli_num_rows($result) > 0)
{
while($row = mysqli_fetch_assoc($result))
{
$rows['catid'] = $row['catid'];
$rows['catname'] = $row['catname'];
$rows['productid'] = $row['productid'];
$rows['prodname'] = $row['prodname'];
$rows['prodimg'] = $row['prodimg'];
$row2[]=$rows;
}
}
echo "<pre>";
print_r($row2);
echo "</pre>";
它给出了这样的数组
Array
(
[0] => Array
(
[catid] => 2
[catname] => C1
[productid] => 13
[prodname] => P1
[prodimg] =>
)
[1] => Array
(
[catid] => 2
[catname] => C1
[productid] => 14
[prodname] => P1
[prodimg] =>
)
[2] => Array
(
[catid] => 2
[catname] => C1
[productid] => 15
[prodname] => P3
[prodimg] =>
)
)
但我想要的最后一个数组代替上面的数组是
Array
(
[0] => Array
(
[catid] => 2
[catname] => C1
[productid] => 13
[prodname] => P1
[prodimg] =>
[size] => Array
(
[0] => small
[1] => medium
[2] => large
[3] => perpiece
)
[cost] => Array
(
[0] => 10
[1] => 20
[2] => 30
[3] => 12
)
[purchasedsize] => Array
(
[0] => small
[1] => 0
[2] => large
[3] => 0
)
[purchasedquantity] => Array
(
[0] => 2
[1] => 0
[2] => 1
[3] => 0
)
[userid] => 1
)
[1] => Array
(
[catid] => 2
[catname] => C1
[productid] => 14
[prodname] => P1
[prodimg] =>
[size] => Array
(
[0] => small
[1] => medium
[2] => large
[3] => 0
)
[cost] => Array
(
[0] => 15
[1] => 20
[2] => 25
[3] => 0
)
[purchasedsize] => Array
(
[0] => 0
[1] => medium
[2] => 0
[3] => 0
)
[purchasedquantity] => Array
(
[0] => 0
[1] => 1
[2] => 0
[3] => 0
)
[userid] => 1
)
[2] => Array
(
[catid] => 2
[catname] => C1
[productid] => 15
[prodname] => P3
[prodimg] =>
[size] => Array
(
[0] => 0
[1] => medium
[2] => 0
[3] => perpiece
)
[cost] => Array
(
[0] => 0
[1] => 20
[2] => 0
[3] => 18
)
[purchasedsize] => Array
(
[0] => 0
[1] => 0
[2] => 0
[3] => 0
)
[purchasedquantity] => Array
(
[0] => 0
[1] => 0
[2] => 0
[3] => 0
)
[userid] => 0
)
)
产品表的视图(正如您将看到产品表带有产品,每个产品下有最大4个尺寸(不会超过4个))
id catid catname productid prodsize cost prodname prodimg
1 2 C1 13 small 10 P1
2 2 C1 13 medium 20 P1
3 2 C1 13 large 30 P1
4 2 C1 13 perpiece 12 P1
5 2 C1 14 small 15 P2
6 2 C1 14 medium 20 P2
7 2 C1 14 large 25 P2
8 2 C1 15 perpiece 18 P3
9 2 C1 15 medium 20 P3
推车桌看法
id catid catname userid productid prodname prodsize quantity prodcost
1 2 C1 1 13 P1 large 1 30
2 2 C1 1 13 P1 small 2 10
3 2 C1 1 14 P2 medium 1 20
任何人都可以帮助我获得所需的数组作为结果？
