如何查看我的v_total_quantity.total_quantity_box < $request->input('quantity_box')[$i];
当我在这里提交数据是我的桌子和我的控制器
id_w | id_p | product_name| total_quantity_box
10 | 1 | snack |10
10 | 2 | watebottle |10
10 | 3 | headphone |10
for ($i=0; $i < $count; $i++) {
$warehouse_products_sell = New Warehouse_products_sell;
$warehouse_products_sell->id_w = $request->input('idw');
$warehouse_products_sell->id_c = $request->get('id_c')[$i];
$warehouse_products_sell->id_p = $request->get('id_p')[$i];
$warehouse_products_sell->quantity_box = $request->input('quantity_box')[$i];
$warehouse_products_sell->price = $request->input('price')[$i];
$warehouse_products_sell->serial_num = $a;
$a = DB::table('v_total_quantity')
->select([
'v_total_quantity.id_w',
'v_total_quantity.id_p',
'v_total_quantity.total_quantity_box',
'products.product_name',
'products.product_unit',
'products.id_product',
])
->leftjoin('products', 'v_total_quantity.id_p', '=', 'products.id_p')
->where([
['v_total_quantity.id_w', '=', $request->input('idw')],
['v_total_quantity.id_p', '=', $request->input('quantity_box')],
]);
// if ($a->id_p < $request->input('quantity_box')) {
// echo "success";
// }else{
// echo "error";
// }
// $warehouse_products_sell->save();
}
但它不起作用
在我的blade_temp中我使用了动态添加,这就是为什么我要去[$ i]
<select style="width:48%;" class="productname" name="id_p[]">
<option value="0" disabled="true" selected="true"> Product Name</option>
</select>
我想确保我的total_quantity_box不是 -
