Need Help with php shopping cart

dwain_francis

Can someone help me out with this code:

I am sending values via a form to a session array but it is not storing the values, so everytime I click the submit button it is supposed to increment but it is not doing that.

This is the form:
<form method="post" action="">
<input name="Title" type="hidden" value="$5 Donation With Shipping" />
<input name="Price" type="hidden" value="5.00" />
<input type="submit" name="Submit" value="Add To Cart" />
</form>

and this is the shopping cart script:
<?php
session_start();
$SESSION['id'] = $POST['isbn'];
$title = $POST['title'];
$qty = $POST['cmd'];
$new =0;
if(!isset($SESSION['id']))
{
$SESSION['cart'] = array();
$SESSION['title'] ='';
$SESSION['price'] = '0.00';
echo $new . $SESSION['title'];
}else{
$SESSION['cart'] = array($title => $qty);
$_SESSION['id']++;
}

foreach ($_SESSION['cart'] as $key => $value)
{

echo '<table><tr><td>' . $value . '</td></tr></table>';
}
?>

Can someone help me please

This condition...

if(!isset($_SESSION['id']))

...will never execute, since a few lines before it you set the value of $_SESSION['id'].

Hi,

I might be wrong here, but it looks like you are trying to increment the value of $SESSION['cart'] when $SESSION['cart'] is an array. if you are trying to skip to an increment of an array, shouldn't you set that value in another variable such as $_SESSION['cartCount'] ?

Try this:

session_start();
$_SESSION['cart'] = array(
"title" => $_POST['title'],
"price" => $_POST['price'],
"author" => $_POST['author'],
"qty" => $_POST['cmd']);
// Check To See If Cart Exists, And Set Count Accordingly
$new = "";  //whats this?
echo "<pre>";
print_r($_SESSION['cart']);  //what does it print out?
echo "</pre>";
/*
if(isset($_SESSION['cart']))
{
$_SESSION['cart']++;
}else{
$_SESSION['cart'] = 1; //huh? maybe you ment to set a new key count in the $_SESSION['cart'] array.
*/
}

HI überfuzz

It is supposed to print the values passed from this form

And how do you set that value in another variable such as $_SESSION['cartCount'] ?
In order to print the items in the cart everytime I press the add to cart button?

So what do I have to do to solve this problem?
