Question

I have been battling with this code for quite a while and just don’t seem to be able to get it to work.

Have tried quite a few variants of the configuration but to no avail. The most confusing part is that it works absolutely fine for displaying a product catalogue (with different variables) but just not this!

errors are:

( ! ) Notice: Undefined variable: quotes in C:\wamp\www\longlifedecking\quote.php on line 40 Call Stack
#   Time    Memory  Function    Location 1  0.0089  689992  {main}( )   ..\quote.php:0

( ! ) Warning: Invalid argument supplied for foreach() in C:\wamp\www\longlifedecking\quote.php on line 40 Call Stack
#   Time    Memory  Function    Location 1  0.0089  689992  {main}( )   ..\quote.php:0

and the code which I have combined is:

<?php include 'inc/header.php'; ?>


<?php include 'inc/dbconnect.php'; ?>  


<?php
// Quotes link from Nav

$sessionProdId = $_SESSION["cart"];


$result = mysqli_query($link, "SELECT prod_id, prod_name, prod_text FROM products WHERE prod_id ='$sessionProdId'");
if (!$result)
{
$error = 'Error fetching products: ' . mysqli_error($link);
include 'error.php';
exit();
}
while ($row = mysqli_fetch_array($result))
{
$quotes[] = array('id' => $row['prod_id'], 'name' => $row['prod_name'], 'text' => $row['prod_text']);
}

?>


    <section id="ctrCol" class="fl">
      <section class="partFill lrgMod ctr">
        <header>
          <h1>Quote me</h1>
        </header>
        <p>Your shopping cart contains <?php echo count($_SESSION['cart']); ?> items.</p>

        <?php  Print_r ($_SESSION); ?> 

        <div class="partFill">
          <ul>

          <?php foreach ($quotes as $quote): ?>
            <li>
              <h3><?php echo htmlspecialchars($quote['name'], ENT_QUOTES,'UTF-8'); ?></h3>
              <p><?php echo htmlspecialchars($quote['text'], ENT_QUOTES,'UTF-8'); ?></p>
             </li>
          <?php endforeach; ?>

          </ul>
        </div>

      </section>
    </section> <!-- end of ctrCol -->
<?php include 'inc/rightnav.php'; ?>   
<?php include 'inc/footer.php'; ?>   

My apologies if this post isn’t formatted correctly but this is my first post and just getting used to it!

Many thanks all.

Answer 1

Finally got the problem sorted. The issue was that no value was being passed to the variable for the MySQL query.

I was not using the session’s array properly. To use the ID’s held within the session I had to
implode the array.

$sessionProdId = implode(",",$_SESSION['cart']); 

$result = mysqli_query($link, "SELECT prod_id, prod_name, prod_text FROM products WHERE prod_id IN ($sessionProdId)");

This then allows the output to function correctly with the previous code.
