Error messages on the same asp page?

[yapjiwen]

How do we make it so that error messages appear in the same asp page as the form? I am not keen on having error messages displayed in a new page...Your comments will be appreciated ...thanks...

After your validation script is done, if there are errors, redirect back to the form and pass the error codes?

Are you trying to do something like this?

dim error
dim errorNum
dim var1 'just an exemple of the different checks you can make with a vars
dim var2
dim var3
error = "<font face=""arial"" size=""2"" color=""red"">" 'should rather be done using CSS
errorNum=0

if request.form("action") = "submit" then 'implies that you have a button named 'submit' to validate your form

if Len(var1) = 0 then
error= error & "enter something."
errorNum=1
end if

if request.form("var2") <> request.form("var3") then
error= error & "<br />enter twice the same value"
errorNum=1
end if

if var1 = request.form("var2") then
error= error & "<br />please enter different values</font>"
errorNum=1
end if

if InStr("=", var1) = True or Instr("*", var1) = True or Instr("'",var1) = True or Instr("%",var1) = True or Instr("_",var1) = True then
error = error & "<br />forbidden chars"
errorNum=1
end if

'check for errors

if errorNum = 0 then

'do whatever you want with your data

end if
end if

error = error & "</font><br /><br />"

if request.form("action") <> "submit" or errorNum > 0 then

response.write (error)

' display your form with: action=" & Request.ServerVariables ("SCRIPT_NAME") & "
' and: <input type="submit" value="submit" name="action">

end if

I was in hurry... If something goes wrong let me know.
