laravel 4 form submit with multiple input - php

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]));
}

Answer 1

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.

Answer 2

I recommend you to use Eloquent model to insert an ITEM data like this way and also loop thru for all the items in your result set:-
Use input class to get POST and GET variables in laravel way
Input::get('invoice_id')
method get() - returns the POST and GET vars
method e() - Convert HTML characters to entities and defined in laravel/helper.php
Use Eloquent to add new row in db in laravel way like:-
item_description::create($arr);
A simple example that is adding an item to item_description table in a cleaner Laravel way:-
$arr = array(
'invoice_id' => e(Input::get('invoice_id')),
'item' => e(Input::get('item')),
'description' => e(Input::get('desc')),
'unit_price' => e(Input::get('unitAmt')),
'quantity' => e(Input::get('qty')),
'amount' => e(Input::get('amount')),
);
// Insert Data in table
$item_description= item_description::create($arr);
