如何使用ID相同的變量值使用PHP INSERT將數組存儲到mysql

Question

因此，我正在嘗試存儲_SESSION數組的值，這將使購物車在我的網站上正常工作。 我在向數據庫中插入相同的數組時遇到了麻煩-我猜我對多個數組有相同的ID，因此這是行不通的。 那是我的猜測。 我希望有一個人可以幫助我。

這是我第一次嘗試。

 <? $con = mysql_connect('bluecubecreatives.net', 'bluecu6_user', '*****'); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("bluecu6_databasename", $con); $itemsupdate = "INSERT INTO orderitems (ID, ORDER_ID, ITEM_ID, NAME, QUANTITY, SIZE, FOR, PRICE, TOTAL) VALUES (NULL, '$id', '$item_stock_id', '$item_name', '$item_quantity', '$item_size', '$item_for', '$item_price', '$item_total');"; mysql_query($itemsupdate); ?> 

這是我第二次嘗試修復它。

 $additems = array ('ID' => NULL, 'ORDER_ID' => $item_id, 'ITEM_ID' => $item_stock_id, 'NAME' => $item_name, 'QUANTITY' => $item_quantity, 'SIZE' => $item_size, 'FOR' => $item_for, 'PRICE' => $item_price, 'TOTAL' => $item_total); $update = "INSERT INTO orderitems (ID, ORDER_ID, ITEM_ID, NAME, QUANTITY, SIZE, FOR, PRICE, TOTAL) VALUES"; $it = new ArrayIterator( $additems ); // a new caching iterator gives us access to hasNext() $cit = new CachingIterator( $it ); // loop over the array foreach ( $cit as $value ) { // add to the query $sql .= "('".$cit->key()."','" .$cit->current()."')"; // if there is another array member, add a comma if( $cit->hasNext() ) { $sql .= ","; } } 

這里是完整的代碼，我正在嘗試將SESSION項目以及帳單+運送詳細信息推送到數據庫中。

 $connection = mysql_connect('bluecubecreatives.net', 'bluecu6', '****'); $selected = mysql_select_db("bluecu6", $connection) or die("Hello ONE, Sorry! This AI system couldn't connect to your database."); if (!$connection) { die('Could not connect: ' . mysql_error()); } if (isset($_GET['id'])) { $id = $_GET['id']; } else { $id = 1; } if (isset($_GET['size'])) { $size = $_GET['size']; } else { $size = "Standard"; } if (isset($_GET['quantity'])) { $quantity = $_GET['quantity']; $cart_update = 1; } else { $quantity = 0; $cart_update = 0; } if (isset($_GET['for'])) { $for = $_GET['for']; } else { $for = "All Purpose"; } if (isset($_GET['action'])) { $action = $_GET['action']; } else { $action="empty"; } $data = mysql_query("SELECT * FROM products WHERE ID= '" . $id . "';" ,$connection) or die(mysql_error()); $val = mysql_fetch_array($data); if ($action=="add") { $newitem = array ('id' => $id , 'name' => $val['PRO_NAME'], 'quantity' => $quantity, 'size' => $size,'for' => $for,'price' => $val['PRO_RS']); $_SESSION['item'][$id] = $newitem; } $_SESSION['quantity'] = $_SESSION['quantity'] + $cart_update; $in_cart = $_SESSION['quantity']; $_SESSION['cart_total'] = $in_cart; if ($_SESSION['cart_total'] <=0) { $_SESSION['cart_total'] = 0; } if ($id!=0) { switch($action) { case "view": if (isset($_SESSION['cart'][$id])) { $_SESSION['cart'][$id]; } else { $_SESSION['cart'][$id]=0; } break; case "refresh"; session_destroy(); break; case "delete"; if ($_SESSION['cart_total']==1) { $_SESSION['cart_total']=0; unset($_SESSION['item']); session_destroy(); } else if ($_SESSION['cart_total']>1) { $_SESSION['quantity']--; $_SESSION['cart_total']--; unset($_SESSION['item'][$id]); } break; case "add": if (isset($_SESSION['cart'][$id])) { $_SESSION['cart'][$id]++; } else { $_SESSION['cart'][$id]=1; } break; case "remove"; if (isset($_SESSION['cart'][$id])) { $_SESSION['cart'][$id]--; if ($_SESSION['cart'][$id]==0) { unset($_SESSION['cart'][$id]); $_SESSION['cart_total']--; } if ($_SESSION['cart'][$id]==-1) { unset($_SESSION['cart'][$id]); $_SESSION['cart_total']--; } } break; case "empty"; unset($_SESSION['cart']); $_SESSION['cart_total'] = 0; break; } } if($_POST['ADD_TOCONFIRM']){ $shipping_option = $_POST['shipping_option'];$payment_option = $_POST['payment_option'];$discount_val = $_POST['discount_val']; $bname = $_POST['name'];$baddress = $_POST['address'];$bcity = $_POST['city'];$bprovince = $_POST['province'];$bzip = $_POST['zip']; $bcountry = $_POST['country'];$bcontact = $_POST['contact'];$bemail = $_POST['email']; $sname = $_POST['sname'];$saddress = $_POST['saddress'];$scity = $_POST['scity'];$sprovince = $_POST['sprovince'];$szip = $_POST['szip']; $scountry = $_POST['scountry'];$scontact = $_POST['scontact'];$semail = $_POST['semail']; $status = "Pending"; // foreach ( $_SESSION['item'] AS $data ) { $xo = mysql_query("SELECT * FROM products WHERE ID= '" . $data['id'] .

Answer 1

假設您有以下數組，

$additems = array ('ID' => NULL, 'ORDER_ID' => $item_id, 'ITEM_ID' => $item_stock_id, 'NAME' => $item_name, 'QUANTITY' => $item_quantity, 'SIZE' => $item_size, 'FOR' => $item_for, 'PRICE' => $item_price, 'TOTAL' => $item_total);    

您可以像執行查詢

$update =  "INSERT INTO orderitems (ORDER_ID, ITEM_ID, NAME, QUANTITY, SIZE, FOR, PRICE, TOTAL) VALUES ($additems['ORDER_ID'],$additems['ITEM_ID'],$additems['NAME'],$additems['QUANTITY'],$additems['SIZE'],$additems['FOR'],$additems['PRICE'],$additems['TOTAL'])";

試試這個，這應該工作。 隨時詢問您是否對此有任何疑問。

Answer 2

所以這是我的代碼出了什么問題。 我從mysql中提取了INSERT代碼，並在我的PHP文件中對其進行了配置。 突然，一切都開始了。

 $itemupdate = "INSERT INTO `orderitems`(`SESSION_ID`, `ORDER_ID`, `ITEM_ID`, `NAME`, `QUANTITY`, `SIZE`, `FOR`, `PRICE`, `TOTAL`, `NOTES`) VALUES ('$session_no','$item_id','$item_stock_id','$item_name','$item_quantity','$item_size','$item_for','$item_price','$item_total','notes');"; mysql_query($itemupdate);
