Dropped SESSION issue

[ryan.od]

Can anyone see why the link to the products page shown below would drop my SESSION? If I change the link to just products.php, the SESSION stays active. The way it is now, the SESSION is dropped (even though the link works fine). $root is defined as "" as this is on my home page. Also, I tried taking $root out and that didn't help. The only way to keep the SESSION alive is to change the link to href="../products/". There must be some sort of conflict with passing a variable in the URL?

 

	<?php			
		$sql = "SELECT * FROM product WHERE product_featured = 1";
		$result = mysql_query($sql) or die('<p>Unable to perform product query. Error: ' . mysql_error() . '</p>');

		while($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
			echo('<div class="product_mini"><a href="' . $root . 'products?prod_id=' . $row[prod_id] . '"><img class="product_thumb" src="' . $row[product_image] . '" /></a></div>');
		}
	?>

 

Thanks.

OK, I fixed this ridiculous problem. I wanted to share the final result so as to save others from the same pain. Also, I don't understand why my solution worked. Hopefully, someone can enlighten me.

 

Initially, the product images on the home page were linked to the actual product pages as follows:

 

echo('<div class="product_mini"><a href="' . $root . 'products?prod_id=' . $row['prod_id'] . '"><img class="product_thumb" src="' . $row[product_image] . '" /></a></div>');

 

This approach ALWAYS dropped the $_SESSION. However, if I change it to the following (I put a forward slash after the directory name) it maintains the $_SESSION:

 

echo('<div class="product_mini"><a href="' . $root . 'products/?prod_id=' . $row['prod_id'] . '"><img class="product_thumb" src="' . $row[product_image] . '" /></a></div>');

 

Can anyone tell me why this happens? Maybe it has something to do with targeting the index.html file in a lower directory by just targeting the folder name?
