Hi all,
I have a pretty nice paging function. However, i want the visitor to be able to set the amount of records they want to see. When they dont set how many they want to see, the default value takes over, when they do set it, the script goes mad and just shows all the records. here is the code that deteremines the amount ot records to show
----------------------------------
Dim NUMRS
NUMRS = Request.FORM("PGS")
IF NUMRS = "" Then
NUMRS = 10
End If
PAGESIZE = NUMRS
-----------------------------------------
BTW, if i do it like this, the script goes mad and shows the all the records
------------------------------------------
Dim NUMRS
NUMRS = Request.FORM("PGS")
IF NUMRS = "" Then
NUMRS = "10"
End If
PAGESIZE = NUMRS
-----------------------------------------------
Could it be that if the user submits a value, the script puts it as "Newvalue" ??
Any help is greatly appreciated.
Thanks,
Regards,
Spoon, (ya all love me right?) |

Spoon,
It should work like the first example you posted.
One thing to check: are you sure you are using POST ?
If you want to be able to pass the pagesize in the url, you'll need to use Request.QueryString() instead of Request.Form()
If you want to be able to both retrieve it from a form use POST and still be able to use it in a url, you can use Request() without any of the two. This last one is slower that the other two so should only be used if you want to be able to get the value no matter what method is used.

Spoon,
Could you tell something more about the error you get when the script goes mad, did you try a
Response.write(PAGESIZE)
Response.end
right after the code you posted to check if the value is passed ok.
If it get into the variable ok, the problem is further down the road/code.

another quick question, the pagesize variable that you're assigning the NUMRS value into, what are you doing with that? Is it just sitting there doing nothing, or are you appending it to your recordset page size later on?
i.e.
RecordSetName.PageSize = Pagesize 'or
RecordSetName.PageSize = NUMRS

Hi again,
Gor, the variable is being past through the script fine, i have PAGESIZE written on the page, "Set number of records to show" then a textbox with PAGESIZE is written in it.
When i dont set the var PAGESIZE the script sets to it to 10 as default, when i submit a new value of PAGESIZE through the form, no matter what number value it is, the script then just shows all the records that are in the database. I dont get an error, thats just what happens :(
ID:
The only reason NUMRS is there is cause i was trying a different way of getting it to work, thats all. NUMRS is not called again after PAGESIZE = NUMRS
Thanks for trying guys

This may be completely off the wall, but try doing this
<%
If Request.Form("PGS") <> "" Then
NUMRS = CInt(Request.Form("PGS"))
Else
NUMRS = 10
End If
Recordset.PageSize = NUMRS
%>
The reason i say convert it to an integer is because i think when it's being taken from the form it's being interpreted as a string, and I don't think you can pass a string into the pagesize.
If that doesn't work, i don't know what else to tell you to try

Thanks so Much ID. It worked!!!! :) :) :) :)
I got rid of numrs and applied the same principal after that ---
PAGESIZE = Request.Form("PGS")
If PAGESIZE = "" Then
PAGESIZE = 10
Else
PAGESIZE = Cint(PAGESIZE)
End If
Thanks to you both of you for helping me
Thanks again :)
