    Since updating to PHP 8.0, I’m getting the following error:

    PHP message: PHP Fatal error: Uncaught TypeError: call_user_func(): Argument #1 ($callback) must be a valid callback, non-static method PMProRH_Field::saveFile() cannot be called statically in /www/austa_486/public/wp-content/plugins/pmpro-register-helper/pmpro-register-helper.php:937

    I’ve taken a look at pmpro-register-helper.php line 937, which contains the following:

    if(!empty($field->save_function))
        call_user_func($field->save_function, $user_id, $field->name, $_POST[$field->name]);

    And then at class.field.php:

    elseif($this->type == "file")
    {
    	//use the file save function
    	$this->save_function = array("PMProRH_Field", "saveFile");
    }

    Any thoughts?

    So I went into classes/class.field.php and edited line 146 and added ‘static’

    From
    function saveFile($user_id, $name, $value)

    To
    static function saveFile($user_id, $name, $value)

    And now it is working. Since PHP 8.0 is more strict with syntax, it doesn’t allow static calling of non-static methods. Perhaps this should be updated all throughout the plugin, or does anybody have any other workarounds?

    WordPress should be updated in its entirety to be completely honest, along with a whole boat load of plugins. There are plenty of websites out there claiming that WP is 100% compatible with PHP 8+, but this is a lie as I’m writing thins. Install a plugin such as Query Monitor and you’ll very quickly see how incompatible it actually is.

    Expect another 6 months+ before this issue is sorted. In the meanwhile “hacks” such as yours will need to be the order of the day. Well done for figuring it out btw.
