我创建了一个foreach循环，其中包含带有产品信息的数据-id，价格，团体价格...我可以使用$_POST上的var_dump访问数据并查看数据。但是我无法将所有数据保存在数据库中。每次只保存上一个产品的信息。如何将所有产品保存在这两个表stack和product中？这是我的代码：
$postedStacksArray = array();
$postedStacksArray = array();
$postedproductsArray = array();
$postedStacksDetailsArray =
foreach ($_POST['Product']["rel_stacks"] as $keyStack => $rel_stack){
if(isset($rel_stack[0])){
$postedStacksArray['product_id'] = $rel_stack;
$postedproductsArray[] = (int)$rel_stack[
$postedStacksDetailsArray[$keyStack]['product_id'] = (int)$rel_stack[0];
$postedStacksDetailsArray[$keyStack]['price'] = $rel_stack['price'];
$postedStacksDetailsArray[$keyStack]['price_gr2'] = $rel_stack['price-gr2'];
$postedStacksDetailsArray[$keyStack]['price_gr3'] = $rel_stack['price-gr3'];
}
}
$savedStackArray = ArrayHelper::map(ProductStack::find()->where('stack_id = :stack_id and product_id=:product_id', ['stack_id' => $model->attribute_set_id, 'product_id' => $model->id])->all(), 'stack_id', 'stack_id');
$stackForSaveArr = array_diff($postedStacksArray, $savedStackArray);
$stackForDeleteArr = array_diff($savedStackArray, $postedStacksArray);
foreach ($stackForSaveArr as $keyStack => $stak) {
$stack = new Stack;
$stack->product_id = $postedStacksArray['product_id'];
if(isset($stak['product_id']) and !empty($stak['product_id'])) {
$desc_product = Product::findOne($stak['product_id']);
if ($desc_product) {
if (isset($postedStacksDetailsArray["price"]) and !empty($postedStacksDetailsArray["price"])) {
$stack->price_disc_gr1 = $desc_product->price_online - $postedStacksDetailsArray["price"];
}
if (isset($postedStacksDetailsArray["price_gr2"]) and !empty($postedStacksDetailsArray["price_gr2"])) {
$stack->price_disc_gr2 = $desc_product->price_online_gr2 - $postedStacksDetailsArray["price_gr2"];
}
if (isset($postedStacksDetailsArray["price_gr3"]) and !empty($postedStacksDetailsArray["price_gr3"])) {
$stack->price_disc_gr3 = $desc_product->price_online_gr3 - $postedStacksDetailsArray["price_gr3"];
}
}
}
$stack->price_gr1 = $postedStacksDetailsArray["price"];
$stack->price_gr2 = $postedStacksDetailsArray["price_gr2"];
$stack->price_gr3 = $postedStacksDetailsArray["price_gr3"];
$stack->user_id = Yii::$app->user->identity->id;
$stack->save(false);
$newPrd = new Product;
$newPrd->type = 2;
$newPrd->parent_id = $model->id;
$newPrd->price_online = $postedStacksDetailsArray["price"];
$newPrd->price_online_gr2 = $postedStacksDetailsArray["price_gr2"];
$newPrd->price_online_gr3 = $postedStacksDetailsArray["price_gr3"];
$newPrd->active = 1;
$newPrd->in_stack = 1;
$lastStack = Stack::find()->orderBy(['id' => SORT_DESC])->one();
$newPrd->attribute_set_id = $lastStack->id;
$newPrd->artic_number = $keyStack.$model->id;
$newPrd->save(false);
}
这是我要保存的$_POST
array(3) { ["first"]=> array(4) { [0]=> string(3) "709" ["price"]=> string(1) "4" ["price-gr2"]=> string(1) "3" ["price-gr3"]=> string(1) "2" }
["second"]=> array(4) { [0]=> string(3) "707" ["price"]=> string(2) "19" ["price-gr2"]=> string(2) "18" ["price-gr3"]=> string(2) "17" }
["last"]=> array(4) { [0]=> string(4) "1251" ["price"]=> string(1) "7" ["price-gr2"]=> string(1) "6" ["price-gr3"]=> string(1) "5" } }

您在这里回答：
$postedStacksArray = array();
$postedproductsArray = array();
$postedStacksDetailsArray = array();
foreach ($_POST['Product']["rel_stacks"] as $keyStack => $rel_stack){
if(isset($rel_stack[0])){

$postedproductsArray[] = (int)$rel_stack[0];
$postedStacksDetailsArray[$keyStack]['product_id'] = (int)$rel_stack[0];
$postedStacksDetailsArray[$keyStack]['price'] = $rel_stack['price'];
$postedStacksDetailsArray[$keyStack]['price_gr2'] = $rel_stack['price-gr2'];
$postedStacksDetailsArray[$keyStack]['price_gr3'] = $rel_stack['price-gr3'];
}
}

$stackForSaveArr = array_diff($postedproductsArray, $savedStackArray);
$stackForDeleteArr = array_diff($savedStackArray, $postedproductsArray);
foreach ($postedStacksDetailsArray as $keyStack => $stak) {
$stack = new Stack;

我认为您的第一个问题是问题。 postedStacksArray它仅存储post值中的最后一个信息。一次打印postedStacksArray并检查
