sistema paginazione

Ugo · Messaggio da **Ugo** » 09/06/2010, 17:25

ciao,
all'interno di ogni categoria del mio negozio ho applicato la paginazione(numeretti a fondo pagina per dividere in più pagine i miei prodotti).
Quando clicco in una categoria la prima pagina che mi appare è quella con gli ultimi inserimenti e fin qui tutto bene.
Quando però ad esempio essendo nella quarta pagina clicco sul numeretto 1 per tornare alla prima, non mi rimanda alla pagina
con gli ultimi prodotti inseriti di cui sopra, ma bensì ad un altra pagina 1 che però ha altri prodotti e quindi è diverse dall'altra.
Questo avviene praticamente su tutte le pagine della paginazione.

Come si può risolvere questa cosa?

Grazie in anticipo x ogni aiuto.

controlla la generazione dei link... perchè è strano come errore

Ugo · Messaggio da **Ugo** » 28/06/2010, 14:08

ciao dynamo e grazie innanzitutto per la pronta risposta

come e dove devo controllare esattamente? perdona la mia ignoranza in materia ma non sono un programmatore.

Grazie ancora

nel file catalog/includes/modules/product_listing controlla magari con la versione base di osc così da poter notare eventuali differenze

OK grazie dynamo controllo e poi ti dico subito.

Grazie ancora.

ciao dynamo

ho controllato la pagina "product_listing" con una più recente, ho anche uplodato la pagina recente ma il problema
a livello di paginazione persiste ancora.
A dire il vero quando faccio l'upload della pagina dell'ultimo pacchetto di oscommerce mi da un messaggio di errore
questo perche immagino entra in conflitto con il mio pacchetto che è abbastanza datato (almeno 2 anni) e non è italiano.
La cosa che ho notato tuttavi a sono gli url: quello che appare la prima volta che clicco sulla categoria è il seguente:

http://www.myosito.com/index.php?cPath=22

mentre gli url quando clicco sugli altri numeretti della paginazione sono del tipo:

http://www.myosito.com/index.php?cPath= ... =2a&page=1

e quando rifaccio click sul numeretto 1 non mi da più: http://www.myosito.com/index.php?cPath=22

ma appunto url del secondo tipo: http://www.myosito.com/index.php?cPath= ... =2a&page=1

Come posso risolverla secondo te?...non ci capisco più niente!

    }

la trovi in catalog/includes/classes/split_page_results.php
la funzione serve per lo split delle pagine

Grazie dynamo, stasera controllo e domattina ti faccio sapere se sono riuscito a risolvere

Grazie ancora.

Buongiorno dynamo

ho verificato con il codice che mi hai gentilmente postato ed è uguale a quello presente nella mia pagina.
Non so,..è come se la prima pagina di ogni categoria (1) sia una cosa a se stante rispetto a tutte le altre pagine (2,3,4 etc.)
e quindi la paginazione funziona bene dalla 2 in poi ma non tiene in considerazione la pagina 1 (o meglio per lei la pagina 1 è un altra, non è cioè quella che appare
quando si fa click sul nome della categoria) . A questo punto non so più a che santo votarmi. Hai qualche suggerimento dynamo?

Grazie ancora molto.
