Counter

I pasted the snippet into my functions.php, did a little customizing and set up the counter here: http://www.doro-und-nick.de/test/

The counter displays, but does not show entries from the guest list form (form ID 1). The form is located here: http://www.doro-und-nick.de/gaesteliste/, Field-ID 2 asks for the number of guests (actually the frontend choices are "1+1", "1+2" and so on, but the backend values in the form are straight numbers like 2, 3 etc.).

This is your code after my customizing:

// http://pastebin.com/kHpaHQvi originally
// http://www.gravityhelp.com/forums/topic/show-total-donations
// usage: [gaesteliste form=01] where 37 is the form ID
add_shortcode('guests', 'total_guests');
function total_guests($atts) {
        $form_id = $atts['form'];
        // function to pull all the entries for one form
        $guests = RGFormsModel::get_leads($form_id);
        // start the total at zero
        $total = 0;
        // initialize a counter for the number of guests entries made
        $i = 0;
        // loop through all the returned results
        foreach ($guests as $amount) {
                // add each guest attending to the total
                // change 2 here to the field ID which holds the amount of atteding guests
                $total += $amount[2];
                // increment the counter so we know how many guest entries there are as well
                $i++;
        }
        // change this to your locale, or, if your locale is already defined, you can remove this line
        setlocale(LC_MONETARY, 'de_DE');
        // do some formatting and return the html output from the shortcode
	$output = "Nach bisherigem Stand haben " . money_format('%i', $total) . " Personen ihr Kommen zugesagt.";
        // just the string above will be returned.  You can style it here or where you are using the shortcode
        return $output;
}
// needed for the above to process the guests list shortcode in sidebar widget
add_filter('widget_text', 'do_shortcode');

1. Any suggestions why the form entries are not shown/added?

2. How do I have to change the following line to only show the total number of guests without decimal places and currency? Sry, keep getting errors if i start changing it on my own..

$output = "Nach bisherigem Stand haben " . money_format('%i', $total) . " Personen ihr Kommen zugesagt.";

Hi Chris, thanks for your help. Indeed I was using the wrong shortcode. Additionally WP Debug displayed an error based on wrong customizing in line 41, where i had changed "$form_id = $atts['form'];" to "$form_id = $atts['1'];". After changing it works beautifully now. Here is the fixed snippet for the counter: http://pastie.org/6333047.

Just a final question: My form asks for the number of adults (field id 2) and children (field id 5). How do I have to extend the snippet to get the value for field id 5 as well - not added to the value of field id 2 but separated. I would like to display the guest counter like "So far X adults and Y kids are attending the wedding".

Hi Chris. This is brilliant, exactly what i was looking for. Thanks a lot for your awesome support!
