Question

我有下一个代码：

for (int lowsetLimit = 0, highestLimit = 10, i = lowsetLimit; i < highestLimit; i++)
{
   //normal code which process before i gets eqaul to 5 goes here...

   i = (i < 5) ? i : highestLimit; //and here is the pivot point.
}

我的bestellen.php是：

<?php

$rezOrders = mysqli_query($kon, "SELECT * FROM orders WHERE user_id = ". $user_id ." AND status = 0 ORDER BY id DESC LIMIT 1");
$redOrders = mysqli_fetch_assoc($rezOrders);

$rez = mysqli_query($kon, "SELECT shops.*, shops.naam as shopNaam, shops.id as shopId, shops.producten as shopEtalage, shops.bestel_extra as extra, shops.googlemaps as maps, 
                                          producten.*, producten.naam as prodNaam, producten.details as prodDetails, producten.id as prodID,
                                          product_shop_tt.*, product_shop_tt.price as prodPrijs, 
                                          order_details.*, order_details.aantal as aantal, order_details.id as orderDetID,
                                          type.*, type.naam as typeNaam 
                                          FROM order_details INNER JOIN product_shop_tt ON order_details.product_shop_tt_id = product_shop_tt.id
                                          INNER JOIN shops ON shops.id = product_shop_tt.shop_id
                                          INNER JOIN producten ON producten.id = product_shop_tt.product_id 
                                          INNER JOIN type ON type.id = shops.type_id 
                                          WHERE order_id = ". $redOrders["id"] ."");

$i = 1;
while($red = mysqli_fetch_assoc($rez)){

    echo "<form action=\"bestellen.php?order_detail_id=". $red["orderDetID"] ."\" method=\"post\">";

                  </div>";
                  $i++;

                </button>
            </div>";
            echo "</form>";


?>

在<?php session_start(); include("config.php"); global $kon; ob_start(); //Ovdje provjeravamo koji checkboxes su selektovani if(!empty($_POST['chcWeek'])){ foreach ($_POST["chcWeek"] as $idProdChc => $prodIdChc) { foreach($prodIdChc as $checkbox){ echo "Za id : ". $idProdChc ." Checkbox je ". $checkbox . ""; } } } ob_flush(); }中，如果选中该复选框，则会获得产品的ID和ON。但是，如何才能获得此bestellen.php循环中的数量？

如果选中该复选框并且该产品的数量，我想获得该产品的ID。但我不能。我可以通过其他foreach循环从隐藏字段中获取产品ID和数量，但我不能将所有这三个组合在一起。

提前致谢。

如何获取bestellen.php文件中输入字段的值（本例中为3）？

Answer 1

据我了解，您希望在foreach循环中获得以下输入值:(为了便于阅读，我将\"替换为'）

<input id='quan". $i ."' class='form-control' type='number' value='". $red["aantal"] ."' onChange='proces('quan".$i."', 'txtHidd".$i."'); '/>

我没有看到名字=＆＃34;＆＃34;输入值，因此您必须先添加：

<input name='quan".$i."' id='quan". $i ."' class='form-control' type='number' value='". $red["aantal"] ."' onChange='proces('quan".$i."', 'txtHidd".$i."'); '/>

然后更新处理php代码以包含您的$i变量和复选框。

//Ovdje provjeravamo koji checkboxes su selektovani
if(!empty($_POST['chcWeek'])){
   $i = 1;
    foreach ($_POST["chcWeek"] as $idProdChc => $prodIdChc) {
        foreach($prodIdChc as $checkbox){
            echo "Za id : ". $idProdChc ." Checkbox je ". $checkbox . "";
            echo $_POST['quan'.$i]; // Your quantity in the input
            $i++;
        }
    }
}

我相信你是如何获得数量的。（或者你可能会将它移到外部的foreach而不是内部的那个？这对我来说似乎太复杂了。）

我怎样才能获得foreach循环中的数量？
