How do you pass a value to a redirecting page, such as Error.asp, so that it

will display the proper error message when a client enters and erroneous

input.



For example if a client enters a short password, I would like my Error.asp

to say "Sorry, please enter a longer password."  Other times it might say

"Sorry, username already exists in database" - or something like that.



How can this be done?



thanks,

Hey Jon,



You can do it by using querystrings. eg.



Error.asp?WRONGPASS=3Dyes&USEREXISTS=3Dyes



IMO its better to keep it short like:  WPD for WRONGPASS etc.



Then in your error.asp you use



IF Request.Querystring("WRONGPASS") =3D "yes" THEN

 Response.Write "Sorry, please enter the correct password"

ELSEIF Request.Querystring("USEREXISTS") =3D "yes" THEN

 Response.Write "Sorry username already exists in database"

END IF



You can add as many values to the querystring as you want just attach

new ones with a    &     as shown above.



Regards,



Eoghan

Hi Jon,if I were you I would do this stuff client side.



Have a look at http://javascripts.internet.com in the forms bit, there 

will

be lots of useful stuff, it will also save return trips to the server.



Hope this is useful



Sam

However,

I was presuming that you have already verified that the pass was too

short or the user exists so here is the other part,



on your main page you could have,



IF LEN(Request.form("username") < 8) THEN  'where 8 is a minimum

password length

	Response.Redirect "Error.asp?WRONGPASS=3Dyes"

END IF



You can use a SQL query to check if the user exists in the table if it

does exist then use an IF THEN similar to the one above to redirect them

to the error page with the appropriate querystring.



Hope this helps,



Eoghan

Thanks Eoghan,

I thought about that idea already, but since most of my asp pages don't use

the GET method, I would like a solution without the GET method.  I was

wondering if there is anything in ado that can handle this, before I dig

into javascripts.



oh and, http://javascripts.internet.com/ doesn't seem to work.



thanks,

GET is a method of the browser :-) The browser issues a GET to the server to

get a page. :-). I think you'll find that most of your site works that way

already (either that, or POST).



The other options involve:

a) setting cookies

b) using session variables (which depend on cookies)



But I think passing some indicator in the URL is the most efficient:

page1.asp?Err=1

and you could do a lookup to get the corresponding error message.
