如果语句不起作用，则输出else语句

Question

I'm trying to output the if statement, but instead the else statement shows. I have created a page using Wordpress and assigned this template to the page. I'm trying to show product image and content if number of products is > 0, which it is. But instead it shows the else statement. Can someone please help?

<?php  
/*
Template Name: Product Single Template
*/
$productsPermalink = pods_var('last', 'url');
$singleProductPod = pods('products', $productsPermalink);
$numProducts = $singleProductPod->total();
?>

<?php get_header(); ?>

<section>
<?php  if($numProducts > 0): 
?>

    <h1><?php echo $singleProductPod->field('name'); ?></h1>

    <div class="instructor single">
        <img src="<?php echo $singleProductPod->field('image.guid') ?>" alt="<?php echo $singleProductPod->field('name')?>">
        <p><?php echo $singleProductPod->field('content')?></p>
    </div>


<?php  else: ?>
    <h3>There is no such product: <?php echo $productsPermalink; ?>, please select another product</h3>
<?php endif; ?>

Answer 1

It probably shows the if statement because in the line <?php if($numProducts > 0): you have the condition that if the value $numProducts is less than 0 it should instead execute the else clause.

Try and use die (var_dump ($numProducts)); to see the output and find out what really is going on. While you're at it try using var_dump on $singleProductPod->total(); as well.

Maybe you'll find out that the values of these variables isn't quite what you thought it would be.
