Hi, I am using this function to check for an empty container of a post body:

function wpv_conditional_post_has_content($type, $object) {
$return = 0;
if ( $type == 'posts' ) {
if ( empty( $object->post_content ) ) {
$return = 0;
} else {
$return = count($object->post_content);
}
}
return $return;
}

I got from this article: https://toolset.com/documentation/user-guides/conditional-html-output-in-views/using-custom-functions-in-conditions/

When I updated my php version to 7.3. I started to get a php error:
"Warning: count(): Parameter must be an array or an object that implements Countable in ... "

I need your help to fix this function so it would work for PHP 7.3

Hi there,

Thank you for contacting us and I'll be happy to assist.

That code is shown on the guide as an example and for PHP 7.3+, you can update your code to:

function wpv_conditional_post_has_content($type, $object) {
    $return = 0;
    if ( $type == 'posts' ) {
        if ( empty( $object->post_content ) ) {
        	// return 0 when post's content is empty
            $return = 0;
        } else {
        	// return 1 when post's content is not empty
            $return = 1;
        }
    }
    return $return;
}

After that, you'll be able to use this function in conditional blocks as:

[wpv-conditional if="( wpv_conditional_post_has_content() eq '0' )"]
This post has no content
[/wpv-conditional]

[wpv-conditional if="( wpv_conditional_post_has_content() eq '1' )"]
This post has some content
[/wpv-conditional]

I hope this helps and please let me know how this goes.
