Session Array not working properly

[tonyhodge]

I am making a small shopping basket using sessions and arrays and cannot seem to get the below working. 

<?php
// Start Session
session_start();
// Get product ID
$pid = $_GET['id'];
// Initate Array and add item.
$products = array();
$products[] = $pid
// Add to session
$_SESSION['ids'] = $products;
header("location:../auth/index.php");
?>

$pid is receiving the correct data. But when I attempt to add another item, It does not increment. 

function getBasket() {
    echo '<br />'.sizeof($_SESSION['ids']['$products']);  
}

Any help appreciated. 

 

Thanks

Variables are not interpolated when within single quoted strings.

For more information, The function above is called in the index file. I still cannot get it to work though. I have played with the function and had no success. The table that is produced from the code below takes  me to the array addition then return to the index again where the above functions should display the size of the array. Hope this helps more

    include_once("dbcon.php");
    $query = 'SELECT product_id, product_type, product_name,size,colour,cost FROM products, product_types WHERE products.product_type_id = product_types.product_type_id';
    $result = mysql_query($query) or die('Query Failed'.mysql_error());
    echo '<form method="post" action="#">';
    echo '<table>';
    while ($row = mysql_fetch_array($result)) {
        echo '<tr>';
         echo  '<td>'.$row['product_id'].'</td>';         
         echo  '<td>'.$row['product_name'].'</td>';
         echo  '<td>'.$row['product_type'].'</td>';
         echo  '<td>'.$row['size'].'</td>';
         echo  '<td>'.$row['colour'].'</td>';
         echo  '<td>'.$row['cost'].'</td>';
         echo '<td><input type="text" name="quantity" /></td>';
         echo '<td><a href="../includes/addtocart.php?id='.$row['product_id'].'">Add to cart</a></td>';
         echo '<tr>';
    }
    echo '</table>';
    echo '</form>';

Either the descriptions of your problem is off or your posting code that doesn't seem relevant.

 

What exactly is the issue at hand and can we see some relevant code?

I am creating a shopping basket storing the information in arrays and variables.   From the table produced below, users can select 'add to cart' that takes them to the addtocart.php page

// INDEX.php

 include_once("dbcon.php");
    $query = 'SELECT product_id, product_type, product_name,size,colour,cost FROM products, product_types WHERE products.product_type_id = product_types.product_type_id';
    $result = mysql_query($query) or die('Query Failed'.mysql_error());
    echo '<form method="post" action="#">';
    echo '<table>';
    while ($row = mysql_fetch_array($result)) {
        echo '<tr>';
         echo  '<td>'.$row['product_id'].'</td>';         
         echo  '<td>'.$row['product_name'].'</td>';
         echo  '<td>'.$row['product_type'].'</td>';
         echo  '<td>'.$row['size'].'</td>';
         echo  '<td>'.$row['colour'].'</td>';
         echo  '<td>'.$row['cost'].'</td>';
         echo '<td><input type="text" name="quantity" /></td>';
         echo '<td><a href="../includes/addtocart.php?id='.$row['product_id'].'">Add to cart</a></td>';
         echo '<tr>';
    }
    echo '</table>';
    echo '</form>';

The aim of the addtocart.php page is to store the item in an array then put the array in a session and redirect back to the item page above.  I want to add as many items to the cart as I wish. 

<?php

// ADD TO CART
// Start Session
session_start();
// Get product ID
$pid = $_GET['id'];
// Initate Array and add item.
$products = array();
$products[] = $pid
// Add to session
$_SESSION['ids'] = $products;
header("location:../auth/index.php");
?>

The error is that my code does not add to the array. It only adds one item and I am unsure if this is the correct one.

 

After I am printing out the size of the array with says 1 after adding my first item and still 1 after adding a second. The code for this is below 

echo '<br />'.sizeof($_SESSION['ids']['$products']);

Thank you for time with this.

Replace this:

 

 

$products = array();
$products[] = $pid
// Add to session
$_SESSION['ids'] = $products;

 

With:

$_SESSION['ids'][] = $pid;

[trq]

And this:

 

 

echo '<br />'.sizeof($_SESSION['ids']['$products']);

 

With:

 

echo '<br />'.sizeof($_SESSION['ids']);

Something so simple. Believe it or not I have been working with PHP for a while now just sessions still confuse me.! 

 

Thank you for your help.
