Hi,
    I have a page on my website which is below.  This code picks specials up from my site.  On the page, it basically displays all items which are pulled from my database.  However what I have is some items which have a zero stock level, in which case I want to hide the add to cart image.

I have added this value to my database select statement, which is correct and working:

p.products_quantity

This can be callsed by:

$specials[products_quantity]

So what I need to do is check to see if:

$specials[products_quantity] == "0"

in whcih case don't show this line:

<a href="' . tep_href_link(basename($PHP_SELF), tep_get_all_get_params(array('action')) . 'action=buy_now&products_id=' . $specials['products_id']) . '">' . tep_image_button('button_in_cart.gif') . '</a>

BUT if the product quantity is above > 0, then include this line.  How is this possible?

Thanks

Hopefully I've sorted out the quotes.....

if (  $specials[products_quantity] > "0"  ) {

     echo "<a href='" . tep_href_link(basename($PHP_SELF), tep_get_all_get_params(array('action')) . "action=buy_now&products_id={$specials['products_id']}"'>" . tep_image_button('button_in_cart.gif') . "</a>";

}

Typical - press the button and you see some missing ones...

if (  $specials['products_quantity'] > 0  ) {

     echo "<a href='" . tep_href_link(basename($PHP_SELF), tep_get_all_get_params(array('action')) . "action=buy_now&products_id={$specials['products_id']}"'>" . tep_image_button('button_in_cart.gif') . "</a>";
