请给我一些有关我的代码如何正常工作的建议。我有一个循环,可以给我一个ID和数量,以将每个循环更新到我的数据库中。
但是,当我将其传递给我的私人功能并尝试执行它时,我遇到了错误。我只是PHP/Laravel的初学者。这是我的完整代码:
public function updateProduct(Request $request) {
$ids = array();
foreach ($request->products as $ship_id) {
$product_id = DB::table('shipping_products')->select('product_id','quantity')
->where(['shipping_products.shipping_id'=>$ship_id])
->get();
array_push($ids,$product_id);
}
foreach ($ids as $value) {
foreach ($value as $update) {
$this->updateProductQty($update->product_id,$update->quantity);
}
}
}
private function updateProductQty($product_id, $quantity_order) {
$qty = DB::table('products')->select('quantity')
->where(['products.product_id'=>$product_id])
->get();
$updateTotalQty = $qty - $quantity_order;
DB::table('products')
->where('product_id', $product_id)
->update(array(
'quantity' => $updateTotalQty
));
}
我在此行中有一个错误:
$this->updateProductQty($update->product_id,$update->quantity);
它说错误消息:
Object of class IlluminateSupportCollection could not be converted to int
尝试这样做以检查数据是否是您要寻找的:
foreach ($ids as $value) {
foreach ($value as $update) {
//$this->updateProductQty($update->product_id,$update->quantity);
var_dump($update);
var_dump($update->product_id);
var_dump($update->quantity);
}
}
