laravel 4表单提交多个输入

Question

this is the var_dump($_POST) :

array(18) { ["_token"]=> string(40) "Qg0krYddkI2cnPQBy5T3yGJdQqRBbb9q173MXzoa" ["from_name"]=> string(2) "4r" ["from_address"]=> string(1) "4" ["invoice_id"]=> string(1) "4" ["invoice_date"]=> string(0) "" ["due_date"]=> string(0) "" ["to_name"]=> string(1) "4" ["to_address"]=> string(1) "4" ["item"]=> array(1) { [0]=> string(5) "Hours" } ["desc"]=> array(1) { [0]=> string(2) "44" } ["​unitAmt"]=> array(1) { [0]=> string(1) "4" } ["​qty"]=> array(1) { [0]=> string(1) "4" } ["​amount"]=> array(1) { [0]=> string(2) "16" } ["invoiceNotes"]=> string(2) "44" ["subTotal"]=> string(2) "16" ["total"]=> string(2) "16" ["amtPaid"]=> string(1) "0" ["balDue"]=> string(2) "16" }

As you can see the variable unitAmt is being posted, but I am getting this error when I use it :

ErrorException
Undefined index: unitAmt
open: /var/www/lk/htdocs/app/routes.php
//var_dump($rows);
//var_dump($description);


for($i=0; $i<count($rows);$i++){
    DB::table('item_description')->insert(
    array('invoice_id' => $returnID, 'item' => $rows[$i], 'description' => $description[$i],
    'unit_price' => $_POST['unitAmt'][$i], 'quantity' => $_POST['​qty'][$i], 'amount'=>$_POST['​amount'][$i]));
     }

This works fine for qty and amount which are posted similarly. Same thing is happening at other places also on dumping a variable I can see data is there but when I use it shows undefined index.

Edit : THis is my code in route.php

    var_dump($_POST);

$rows = $_POST['item'];
$description = $_POST['desc'];


 for($i=0; $i<count($rows);$i++){
    DB::table('item_description')->insert(
    array('invoice_id' => $returnID, 'item' => $rows[$i], 'description' => $description[$i],
    'unit_price' => $_POST['unitAmt'][$i], 'quantity' => $_POST['​qty'][$i], 'amount'=>$_POST['​amount'][$i]));
     }

Why are you using Laravel to use standard PHP functions? That kind of insertion code shouldn't be in the routes.php file, it should be in a controller or a closure. You should probably using an Eloquent model to create items. Furthermore, you can use the Input class to retrieve data that is provided by GET or POST parameters.
