How to hide products that do not have an image from a slider carousel

Thanks @corrinarusso

I should be able to use the has_post_thumbnail() as the test for the if statement and it will return true if it does and false if it doesn’t? So i assume i need if else statement?

My code is now as follows: it runs – no errors identified that I can see, but does not do what it I was hoping it would do (hide the products that do not have pictures)

add_filter('wcps_slider_item_class','wcps_slider_item_class_20200303', 10, 2);

function wcps_slider_item_class_20200303($class, $args){
    $product_id = isset($args['product_id']) ? $args[‘product_id’] : '';
    $class .= ' my-custom-class';
	if (has_post_thumbnail()) {
		$class = '.normal {
    		display: inline';
	}
	else {
		$class = '.hide {
    		display: none';}
	
    return $class;
}

Sorry. I’m not understanding.

Thanks @bcworkz for joining the conversation and providing your input. Applogies for the poor structure of the previous posts. Fisrt timer here. Thanks for correcting.

the $args[‘product_id’] was cut and paste from the plugins web page:

The information I recieved there indicated I could access product id from $args variable like $product_id = $args[‘product_id’]; Then I should be able to conditionally add a hidden class to item wrapper by checking if a product image exists or not. That is what I had to go off, so thought I might carry that forward here to see if the forum could assist.

Hope this brings more light to it.

Perhps I am taking the example too literally and I don’t need the $product_id = $args[‘product_id’]; line at all, but use something else.

So I feel I have made some sort of progress. I found a way to access $product which gives me the ability to use get_image_id() which I can then use as the test for my if() statement (anything with an ID greater than 1 will show). Where I had product descriptions and prices, but no images, I now just have blank spaces. So the code gets rid of the product info for products with no images, but not the box/space that it resided in. Perhaps this has to be removed separately??? Here is the code:

add_filter('wcps_slider_item_class','wcps_slider_item_class_20200303', 10, 2);

function wcps_slider_item_class_20200303($class, $args){

    $product_id = isset($args['product_id']) ? $args['product_id'] : '';
	
	$product = wc_get_product( $product_id );
	
	if($product->get_image_id() < 1){
		$class .= ' hidden" <style>
  			display: none;
 		</style>';
	}
    return $class;
}
