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:

Codice PHP:

---

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


---

1244:

Codice PHP:

---

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


---

Di tutorial_cat.php invece:

Codice PHP:

---

'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! :???:

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

Scusami ma non ti ho capito :oops:

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:

Codice PHP:

// page number sequence

exit;
}

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

for($i = 0; $i < $total_pages + 1; $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...
