Warning: Division by zero in /web/htdocs/www.*.*.org/home/*/*.php

Quando vado nella pagina in cui prima ho risolto un errore con radioradianti ecco cosa mi appare:


Warning: Division by zero in /web/htdocs/www.*.*.org/home/includes/functions.php on line 1237

Warning: Division by zero in /web/htdocs/www.*.*.org/home/includes/functions.php on line 1244

Warning: Division by zero in /web/htdocs/www.*.*.org/home/includes/tutorial_cat.php on line 167

Warning: Division by zero in /web/htdocs/www.*.*.org/home/includes/tutorial_cat.php on line 167

E le righe di functions.php interessate sono:

1237:

    $total_pages = ceil($num_items / $per_page); 

1244:

    $on_page = floor($start_item / $per_page) + 1; 

Di tutorial_cat.php invece:

            'PAGE_NUMBER' => sprintf( $lang['Page_of'], ( floor( $start / $tutorial_config['art_pagination'] ) + 1 ), ceil( $total_tutorials / $tutorial_config['art_pagination'] ) ), 

non capisco dove sia l'errore!

[seneca]

$per_page e $tutorial_config['art_pagination'] sembrano valere zero. Dove le valorizzi?

Scusami ma non ti ho capito

Dov'è che assegni a quelle variabili un valore?
Da dove provengono?


Ciao!

Sinceramente non ho trovato la variabile definita, sicuramente è definite attraverso una query ma non capisco dove sia scritto, praticamente le righe interessate con quella variabile sono queste:

//
// Pagination routine, generates
// page number sequence
//
function get_page($num_items, $per_page, $start_item)
{
    $total_pages = ceil($num_items/$per_page);

    if ( $total_pages == 1 )
    {
        return '1';
        exit;
    }

    $on_page = floor($start_item / $per_page) + 1;
    $page_string = '';

    for($i = 0; $i < $total_pages + 1; $i++)
    {
        if( $i == $on_page )
        {
            $page_string = $i;
        }
    }
    return $page_string;
}

function generate_pagination($base_url, $num_items, $per_page, $start_item, $add_prevnext_text = true, $start = 'start')
{
    global $lang;

    $total_pages = ceil($num_items / $per_page);

    if ( $total_pages == 1 )
    {
        return '&nbsp;';
    }

    $on_page = floor($start_item / $per_page) + 1;

    $page_string = '';
    if ( $total_pages > 10 )
    {
        $init_page_max = ( $total_pages > 3 ) ? 3 : $total_pages;

        for($i = 1; $i < $init_page_max + 1; $i++)
        {
            $page_string .= ( $i == $on_page ) ? '<b>' . $i . '</b>' : '<a href="' . append_sid($base_url . '&amp;' . $start . '=' . ( ( $i - 1 ) * $per_page ) ) . '">' . $i . '</a>';

                for($i = $init_page_min - 1; $i < $init_page_max + 2; $i++)

ok..hai postato la funzione che usi per la paginazione...ma dov'è che usi quelle funzioni?? .....in pratica dov'è che metti dei valori in queste variabili?? ---> get_page($num_items, $per_page, $start_item) ecc...
