Buongiorno, mi piacerebbe capire come riconoscere dei campi obbligatori da una pagina sp di inserimento dati su un database access.
Attualmente la pagina ha tutti i campi obbligatori, ma non riesco a capire dov'è che vengono dichiarati dati.
Dunque la pagina è la seguente:
<%
' *** Edit Operations: dichiarazione delle variabili
Dim MM_editAction
Dim MM_abortEdit
Dim MM_editQuery
Dim MM_editCmd
Dim MM_editConnection
Dim MM_editTable
Dim MM_editRedirectUrl
Dim MM_editColumn
Dim MM_recordId
Dim MM_fieldsStr
Dim MM_columnsStr
Dim MM_fields
Dim MM_columns
Dim MM_typeArray
Dim MM_formVal
Dim MM_delim
Dim MM_altVal
Dim MM_emptyVal
Dim MM_i
MM_editAction = CStr(Request.ServerVariables("SCRIPT_NAME"))
If (Request.QueryString <> "") Then
MM_editAction = MM_editAction & "?" & Request.QueryString
End If
' boolean to abort record edit
MM_abortEdit = false
' query string to execute
MM_editQuery = ""
%>
<%
' *** Insert Record: set variables
If (CStr(Request("MM_insert")) = "submit") Then
MM_editConnection = MM_connessione_STRING

MM_fieldsStr = "EVE_TYPE|value|TITOLO|value|FONTE|value|DATA|valu e|DESCRIZIONE|value"
MM_columnsStr = "EVE_TYPE|none,none,NULL|TITOLO|',none,''|FONTE|', none,''|DATA|',none,''|DESCRIZIONE|',none,''"
' create the MM_fields and MM_columns arrays
MM_fields = Split(MM_fieldsStr, "|")
MM_columns = Split(MM_columnsStr, "|")
' set the form values
For MM_i = LBound(MM_fields) To UBound(MM_fields) Step 2
MM_fields(MM_i+1) = CStr(Request.Form(MM_fields(MM_i)))
Next
' append the query string to the redirect URL
If (MM_editRedirectUrl <> "" And Request.QueryString <> "") Then
If (InStr(1, MM_editRedirectUrl, "?", vbTextCompare) = 0 And Request.QueryString <> "") Then
MM_editRedirectUrl = MM_editRedirectUrl & "?" & Request.QueryString
Else
MM_editRedirectUrl = MM_editRedirectUrl & "&" & Request.QueryString
End If
End If
End If

ElseIf (MM_delim = "'") Then ' escape quotes

Else
MM_formVal = MM_delim + MM_formVal + MM_delim
End If
End If
If (MM_i <> LBound(MM_fields)) Then

MM_dbValues = MM_dbValues & ","
End If
MM_tableValues = MM_tableValues & MM_columns(MM_i)

Ho provato a fare delle prove ma senza esito.
