My website started showing this strange error recently which I have been unable to resolve. When I try to view a product, it returns a critical error.
I’ve done some troubleshooting and I realized the theme is the culprit. I have also checked the error log and I saw that this specific line of code is causing the error:
Uncaught Error: Call to a member function is_in_stock() on string in /home/u306409103/domains/apdbrestore.com/public_html/wp-content/themes/custom-theme/woocommerce/single-product.php:45 Stack trace: #0
When you check that line, it says:
<?php if( !$product->is_in_stock() ) : ?>
<div >
<img src="<?php echo imgfolder('out-of-stock.png'); ?>" alt="Out of Stock">
</div>
<?php endif; ?>
To be specific the error is pointing towards the first line:
<?php if( !$product->is_in_stock() ) : ?>
I know the problem is coming from here but don’t know what next to do. What statement can I use here to do away with this error?
Thanks

CodePudding user response：
Finally got the solution to this problem and in case anyone stumbles across this, all I had to do was to update how to get the reference post ID because the existing one is deprecated already.
<?php global $product;
$stock_quantity = get_post_meta($post->ID, '_stock', true);
?>
<?php if ($stock_quantity > 0) : ?>
<div >
<img src="<?php echo imgfolder('out-of-stock.png'); ?>" alt="Out of Stock">
</div>
<?php endif; ?>
CodePudding user response：
Make sure that the $product is not a string or a boolean before checking for stock.
<?php if( is_object($product) && !$product->is_in_stock() ) : ?>
Or, you completly stop processing the template by bailing out at the top if no product was returned like this:
if (!is_object($product)) {
return;
}

Try to put this code, I updated your code a bit.

if ( ! defined( 'ABSPATH' ) ) {
exit; // Exit if accessed directly
}
get_header( 'shop' );
global $product;
?>
