how to pass two arrays to view in codeigniter - php

Question

Im not pro in programming
i have a foreach loop that gets the values from a form calculating the total and subtotal
public function salecal()
{
if ($this->input->post())
{
$i = 0;
$data = array();
$subtotal = 0;
foreach($this->input->post('pname') as $d){
$data[] = array(
'pid' => $this->input->post('pid[]')[$i],
'pname' => $this->input->post('pname[]')[$i],
'quantity' => $this->input->post('qty[]')[$i],
);
foreach ($data as $entry) {
$qty = $entry['quantity'];
$pid = $entry['pid'];
$proname = $entry ['pname'];
}
$value = $this->insert_model->get_price($pid); ///pasing the product id to get the the price from database
foreach ($value->result() as $row)
{
$price = $row->price;
}
$total = $price * $qty; ////Total calculation
$subtotal = $subtotal + $total;/////Sub Total Calculation
$i++;
}
$result = compact("proname", "price", "qty", "total","i", "subtotal");
$this->load->view("bill", $result);
}
}
when i run this code im getting only the finally entered products details but the subtotal is correct
but the data inserting form is dynamic
what i want as result is
user will insert several or one item with quantity
data should be calculated and pass the calculated values to view
but currently im getting it only for the last inserted data please help me how to catch all the datas that user insert to form and how to pass them to view

Answer 1

Because your overwriting the variables consequently so it's passing last overwrite value only . you should make array for each one
This how you need to send all data to view using array
<?php
public function salecal()
{
if ($this->input->post())
{
$i = 0;
$data = array();
$subtotal = 0;
$final_array_collection =array();
foreach($this->input->post('pname') as $d){
$total =0; //reset the total to zero for each product
$pid = $this->input->post('pid[]')[$i];
$pname = $this->input->post('pname[]')[$i];
$quantity = $this->input->post('qty[]')[$i];
$value = $this->insert_model->get_price($pid); ///pasing the product id to get the the price from database
foreach ($value->result() as $row)
{
$price = $row->price;
}
$total = $price * $quantity; ////Total calculation
$subtotal = $subtotal + $total;/////Sub Total Calculation
$final_array_collection[] =array("proname"=>$pname, "price"=>$price, "qty"=>$quantity, "total"=>$total,"i"=>$i, "subtotal"=> $subtotal);
$i++;
}
$result = compact("final_array_collection");
$this->load->view("bill", $result);
}
}
?>
