I am trying to use the following code to check for my custom field for a value of ZERO to then display my div

$mp_price_sort = get_post_meta('mp_product_price');
if ($mp_price_sort  == '0') { ?>
    <div><?php echo do_shortcode('[shortcodes]'.$mp_buy_button.'[/shortcodes]'); ?></div>
<?php } ?> 

However it is interperting as a value of anything, thus displaying the div, but I need it to check for the number 0. How can I fix this?

  • Are you sure mp_product_price is set? Try var_dump($mp_price_sort);

  • How do I use var_dump? Im not familiar. I used the_meta to display values and mp_price_sort is 0 for free products and for other products it is whatever the price is. So I am trying to check for the free products which has a value of 0

  • I get what you are doing, I'm try to establish if $mp_price_sort actually has any value at all. $mp_price_sort = get_post_meta('mp_product_price'); var_dump($mp_price_sort);

  • Ok I used your suggestion and this is what it gives me - bool(false) - which is weird cause it was on a page that has a price of 25.

You are using get_post_meta incorrectly, so it is returning FALSE every time. As PHP equates '0' and FALSE, your div will always be displayed.

The correct syntax for get_post_meta is:

<?php $meta_values = get_post_meta($post_id, $key, $single); ?>

where $post_id is the only required argument.

  • Oh Ok, THANKS! I've used your suggestion and change a few things and now it seems to be working.

This is the code I used -

$mp_price_sort = get_post_meta($post->ID, 'mp_price_sort', true);
if ($mp_price_sort == 0) { ?>
<?php } ?>

    This answer is redundant. @vancoder 's post contains the necessary information and is the correct solution.
