bill.php

<?php
echo $get_row['name'].' x '.$value.' @ $'.number_format($get_row['price'], 2).' = $'.number_format($sub, 2);
?>

Notice: Undefined variable: get_row in C:\xampp\htdocs\shopping\bill.php on line 2

Notice: Undefined variable: value in C:\xampp\htdocs\shopping\bill.php on line 2

Notice: Undefined variable: get_row in C:\xampp\htdocs\shopping\bill.php on line 2

Notice: Undefined variable: sub in C:\xampp\htdocs\shopping\bill.php on line 2
x @ $0.00 = $0.00

anyone know how to do it???

I’m just a newbie in this field…

Answer 1

Add session_start(); to the first line of your first php file. then add

$target_data = $get_row['name'].' x '.$value.' @ $'.number_format($get_row['price'], 2).' = $'.number_format($sub, 2).' <a href="cart.php?remove='.$id.'">[-]</a> <a href="cart.php?add='.$id.'">[+]</a> <a href="cart.php?delete='.$id.'">[Delete]</a><br />' ;
$_SESSION['target_data'] = $target_data;

before echo. Then in your second php file, again add session_start(); to the first line and you may echo value like;

echo $_SESSION['target_data'];
