Uncaught TypeError: sizeof() Fatal error occuring

I get following fatal error when a product category does not have any product. I had to patch the plugin which fixes the issue.

PHP Fatal error: Uncaught TypeError: sizeof(): Argument #1 ($value) must be of type Countable|array, null given in /nas/content/live/pistilflowers/wp-content/plugins/wc-ajax-product-filter/wcapf.php:782\nStack trace:\n#0 /nas/content/live/pistilflowers/wp-content/plugins/wc-ajax-product-filter/widgets/widget-price-filter.php(34): WCAPF->getPriceRange(true)\n#1 /nas/content/live/pistilflowers/wp-includes/class-wp-widget.php(393): WCAPF_Price_Filter_Widget->widget(Array, Array)\n#2 /nas/content/live/pistilflowers/wp-includes/widgets.php(831): WP_Widget->display_callback(Array, Array)\n#3
…..`

Solution

Change Line #782 in wc-ajax-product-filter/wcapf.php from

if (sizeof($price_range) > 1) {

if ($price_range != null && sizeof($price_range) > 1) {

I hope it will help someone.

Thanks

Hi,

I just noticed that I’m seeing a huge white banner at the top of every page that uses HelpieFAQ with a warning “Warning: sizeof(): Parameter must be an array or an object that implements Countable in?/home/customer/www/[client’s url]/public_html/wp-content/plugins/helpie-faq/lib/widgetry/elementor-widget-base.php?on line?262”

I turned off debug mode and the warning disappeared. Thought I should let you know in case this causes bugs in the future.

It’s working but there’s an error with “sizeof()”

This is the error

Warning: sizeof(): Parameter must be an array or an object that implements Countable in /web/htdocs/www.[website-link].com/home/wp-content/plugins/helpie-faq/lib/widgetry/elementor-widget-base.php on line 262

Categories and sub-categories “Warning: sizeof()”

Hey I’m working on a wordpress site and I activated the Ultimate Product Catalog.

When I started working with the catalog everything was alright, now I added some products, categories and sub-categories and no products show up on the catalog page, just this 2 errors:

Warning: sizeof(): Parameter must be an array or an object that implements Countable in C:\xampp\htdocs\wordpress-inventario-otbox\wp-content\plugins\ultimate-product-catalogue\Functions\Shortcodes.php on line 1826

I went to check, and they are about the categories and sub-categories, here are only those lines:

line 1825 and 1826
// Create the categories checkboxes
if ($Sidebar_Item == “Categories” and sizeof($Categories) > 0) {
//

line 1896 and 1897
// Create the sub-categories checkboxes
if ($Sidebar_Item == “Sub-Categories” and sizeof($SubCategories) > 0 and $Sidebar_Order != “Hierarchical”) {
//

How can I solve this problem?

Edit: the php version is 7.3.5

Hi. Got an error on the Media > reSmush.it page.

I am trying the plugin on my local computer and got the following error:
Warning: sizeof(): Parameter must be an array or an object that implements Countable in C:\xampp\htdocs\wp-content\plugins\ultimate-product-catalogue\Functions\Shortcodes.php on line 1617

Warning: sizeof(): Parameter must be an array or an object that implements Countable in C:\xampp\htdocs\wp-content\plugins\ultimate-product-catalogue\Functions\Shortcodes.php on line 1688

Is it possible to fix this and what should I do?
