Custom Field Number 0 different than Null

Hello Alex, I got it! just need add the equal >=
in custom_fields_output_functions.php

geodir_cf_multiselect {
...

 if (count($option_values) >= 1) {
                $html .= '<ul>';
...

I’ve copied the file and pasted it under supreme-directory/geodirectory (also tried supreme-directory/geodirectory/geodirectory-functions) and it’s preferring to grab the original template. Seems like only geodirecotry-templates can be replaced in this way.

My attempt of a filter doesn’t work, maybe this is wrong:

add_filter( 'geodir_custom_field_output_multiselect_var_geodir_cf_multiselect', '_gd_custom_multiselect_output', 10, 3 );

whole filter:

function _gd_custom_multiselect_output( $html, $location, $cf ) {
	// If not html then we run the standard output.
    if(empty($html)){

        if (!empty($post->{$cf['htmlvar_name']})):

            if (is_array($post->{$cf['htmlvar_name']})) {
                $post->{$cf['htmlvar_name']} = implode(', ', $post->{$cf['htmlvar_name']});
            }

            $field_icon = geodir_field_icon_proccess($cf);
            if (strpos($field_icon, 'http') !== false) {
                $field_icon_af = '';
            } elseif ($field_icon == '') {
                $field_icon_af = '';
            } else {
                $field_icon_af = $field_icon;
                $field_icon = '';
            }

            $field_values = explode(',', trim($post->{$cf['htmlvar_name']}, ","));

            if(is_array($field_values)){
                $field_values = array_map('trim', $field_values);
            }

            $option_values = array();
            if (!empty($cf['option_values'])) {
                $cf_option_values = geodir_string_values_to_options(stripslashes_deep($cf['option_values']), true);

                if (!empty($cf_option_values)) {
                    foreach ($cf_option_values as $cf_option_value) {
                        if (isset($cf_option_value['value']) && in_array($cf_option_value['value'], $field_values)) {
                            $option_values[] = $cf_option_value['label'];
                        }
                    }
                }
            }

            $html = '<div class="geodir_more_info ' . $cf['css_class'] . ' ' . $cf['htmlvar_name'] . '" style="clear:both;"><span class="geodir-i-select" style="' . $field_icon . '">' . $field_icon_af;
            $html .= (trim($cf['site_title'])) ? __($cf['site_title'], 'geodirectory') . ': ' : '';
            $html .= '</span>';

        //Comentario - Cambio
            if (count($option_values) >= 1) {
                $html .= '<ul>';
        //Fin        
                foreach ($option_values as $val) {
                    $html .= '<li>' . $val . '</li>';
                }

                $html .= '</ul>';
            } else {
                $html .= __($post->{$cf['htmlvar_name']}, 'geodirectory');
            }

            $html .= '</div>';
        endif;

    }

    return $html; }
add_filter( 'geodir_custom_field_output_multiselect_var_geodir_cf_multiselect', '_gd_custom_multiselect_output', 10, 3 );
