collegare record

**hapax** · 02-09-2005, 12:31

Ho creato la prima pagina con i record costruttori ed i link che puntano alla pagina modello ma non riesco a stampare a video i modelli di ogni marca (cliccando su ogni marca non mi appare niente).
Invece escludendo dalla select il where qualsiasi marca clicco mi escono tutti i modelli presenti nel database.
Cosa devo modificare nel seguente codice per avere per ogni marca i propri modelli?

<%
costruttore = request.querystring( "costruttore")
%>
<table width="900" height="50" border="0" cellpadding="0" cellspacing="0">
<tr>
<td>
<%
set rs = server.createobject("ADODB.recordset")
rs.Activeconnection = "auto"
sql = "SELECT DISTINCT modello FROM [veicoli] WHERE costruttore = ' " & costruttore & " ' "
rs.open sql

do until rs.eof

modello = rs("modello")
response.write(modello&"
")

rs.movenext
loop

rs.close
set rs = nothing
%>
</td>
</tr>
</table>

codice:

costruttore = request.querystring( "costruttore") 
response.write costruttore &"
"

e posta cosa restituisce.

Ho provato a sotituire il codice che mi hai scritto.
-Se eseguo la pagina (modello_inc.asp)singolarmente non mi dà nessun errore, ma una pagina bianca.
-Se eseguo la pagina default.asp con incluso il file modello_inc.asp la pagina si vede correttamente ma quando provo a cliccare sul nome del costruttore mi riporta alla stessa pagina senza nessuna variazione.
Come posso fare?

**fraude** · 02-09-2005, 14:58

Se la pagina è bianca, vuol dire che non si valorizza correttamente la variabile costruttore.

Come la invii alla pagina? con un form o tramite querystring?

**hapax** · 02-09-2005, 15:03

Scusa inviare alla pagina in che senso?
Il codice che deve essere incluso è quello che ho postato prima, quindi con una querystring.

**fraude** · 02-09-2005, 15:05

Posta il codice o i codici completi.

Questo è il primo codice quello dell'include costruttori con la barra che fà scorrere i record.L'ho generato con Dreamweaver.....se hai qualcosa di + semplice inviamelo.
---------------------------------------------------------------------

Ora ti posto il secondo codice quello dell'include modelli dove dovrebbero apparire i record dei modelli in base al costruttore cliccato

<%
costruttore = request.querystring( "costruttore")
response.write costruttore &"
"
%>
<table width="900" height="50" border="0" cellpadding="0" cellspacing="0">
<tr>
<td>
<%
set rs = server.createobject("ADODB.recordset")
rs.Activeconnection = "auto"
sql = "SELECT DISTINCT modello FROM [veicoli] WHERE costruttore = ' " & costruttore & " ' "
rs.open sql

do until rs.eof

modello = rs("modello")
response.write(modello&"
")

rs.movenext
loop

rs.close
set rs = nothing
%>
</td>
</tr>
</table>

che caos...

**hapax** · 02-09-2005, 18:27

Hai ragione, infatti ho deciso di riscrivere tutto da zero senza l'aiuto di dreamweaver.
Mica mi puoi aiutare, sai come fare per realizzare una barra di scorrimento dei recordset con i pulsanti primo-ultimo,record successivo-precedente.(tipo quella che si può fare con dreamweaver, che mi ha fatto tutto quel casino nel codice...)
Grazie.

**fraude** · 02-09-2005, 18:30

hai bisogno di una classe per la paginazione dei recordset, ecco una delle migliori in circolazione:
