Question

is there a way to hide variables when blank.

Asked by: Tony-laptops

hi Experts.

I am trying to find a code that could hide variables that are blank.  In other words, I am using search pages and passing all the variables to page 2, 3 etc when moving to next page results.

What I would like to do is ignore any variables that are empty or not being used to keep the url as short as possible when moving between pages.

Thanks.

you can build up your url based on the contents of the variables, of course.
how do you call the other pages?
what is your current code?

Tony-laptops,

In ASP you can test to see if the variable is blank by using some code like this to build your string.

strquery = "?page=2"
If s <> "" then strquery = strquery & "&s=" & s

And then repeat for the other variables and values.  They are only added if not blank.

Let me know if you have any questions or need more information.

Like b0lsc0tt indicates, you have to build up the url with the parameters like that, variable for variable.

also, on the called page, you have to consider that a parameter is not given at all...

You might also want to consider using POST instead of GET to eliminate all querystring. If so, add method="post" in the form tag

<form .... method="post">

In the search.asp if you are using Request.QueryString("VarName"), change that to Request("VarName")

 

by: NTJOCKPosted on 2006-11-06 at 23:13:25ID: 17887367

yea, it's long code....
but basically you do something like this.

nexturl="http://www.myserver.com/bigpage.asp"
firsttime=0 ' keep track of the ? so you can pass no variables
*********-begin repeating code*********
if variable1<>"" then
if firstime=0 then
nexturl=nexturl&"?variable1="&variable1
else
nexturl=nexturl&"&variable1="&variable1
end if' ? or &
end if ' variable 1

******* end repeating code********

simply repeat that until you've checked all your variables.

If you want to get fancy smancy you can make it a subroutine (i.e. if you have alot of these to do)

nexturl="http://www.myserver.com/bigpage.asp"
firsttime=0 ' keep track of the ? so you can pass no variables

sub checker()
if variable1<>"" then
if firstime=0 then
nexturl=nexturl&"?variable1="&variable1
else
nexturl=nexturl&"&variable1="&variable1
end if' ? or &
end if ' variable 1
end sub

response.redirect("nexturl")


If you need more specific stuff ask.  :)


then call it as
checker variable1
checker variable2
