Selezionare a video dati da tabella

[verbaweb2]

salve,
avrei una domanda da porvi.

io ho una tabella chiamata link in questa tabella ho un campo che si chiama Tipo
che può contentere 3 valori che possono essere A B C

io vorrei che se clicco su A visualizzo tutti i link di tipo A
se clicco su B visualizzo tutti i link di tipo B
e se clicco C visualizzo tutti i link di tipo C

Ovviamente senza creare diverse pagine che in quel modo saprei come fare

vorrei che la apgina restasse semper la stessa ovvero link.asp

Qualcuno sa come aiutarmi

P.S. usi il dreamweaver

[Roby_72]

Spero che la tua pagina link.asp li recuperi già tutti vero?
Vediamola...

Roby

[verbaweb2]

Si li richiamo entrambi...

la pagina è Questa e come vedi li rikiamo tutti..
solo che mi sto accorgendo che i link diventano tanti, quindi preferivo selezione il "tipo" e visualizzarli a video.

in caso + tardi posto il codice che non sono in casa

ciao ciao

Ciao Roby,
hai visto il codice??
a presto

[Roby_72]

Si ma che dire??? Bastava un ventesimo di codice per lo più comprensibile...
1) Devi mettere un link con un parametro
2) Recuperare il parametro del link
3) Modificare la query con SELECT ....

Roby

hai sicuramente ragione che ci voleva 1/2 di quel codice... ma io mi affido al dreamweaver.. non lo faccio per lavoro e mi ci butto a tempo perso sul mio website..
Roby grazie per il cosniglio.. hai un esempio da potermi far vedere??

Grazie mille!!!

[verbaweb2]

ciao Roby...
mi hai abbandonato?

[verbaweb2]

nessuno che mi sa aiutare???

[barney09]

la cosa è molto semplice, pero' va scritta a mano.

Allora, cre un form con all'interno uno select con i parametri richiesti "A" "B" "C" e "TUTTI"

la select la chiami ad esempio PARAMETRO

La form la fai puntare a se stessa cioè a LINK.ASP


Prima di fare la query di selezione, controlli cosa è contenuto nel valore parametro.

Se il contenuto è A B o C aggiungi alla query

"WHERE campo = '"&Request("parametro")&"'"
