Here we start out with a simple "settings" file, named settings.asp. This file will be included on each page, and will contain the basic settings for this guestbook.

Since the password (logincode) is NOT in the database, you can leave the database in the webroot with a mappath statement to make the install easier. However, the best place for the database is outside of your webroot, in which case you would want to change the database_path string to your full path ("C:\inetpub\database\post.mdb" for example)

There is also an important settings to allow html, or not. Many times folks abuse a guestbook by filling it with links, and other junk. It would be a good idea to disallow html, unless you really need it.

The language setting is just a set of variables for text used within the system, for each language there is a different text that is used. Very easy to add a "new" language to the system.

The login is a simple login check page, which checks the login code entered on the form
with the one stored in the settings.asp file.

" title of your guestbook. pagetitle = " Demo" " language " english = en, german = ger, french = fr lang = " en" " admin password logincode = " 1234" " number of entries to show. show_posts = " 25" " minimum length of post to be allowed. minimum_length = 4 " set to "no" for no html, set to "yes" to allow html (not recommended!) allow_html = " no" " leave as is, unless you want to move your database. database_path = Server .MapPath(" post.mdb" ) <%Option Explicit %> <% if Request .Form(" mynumber" ) = " " then response .redirect(" login.asp?l=password_blank" ) End If " set variables from form FormPwd = Request .Form(" mynumber" ) FormPwd = replace (FormPwd," "" ," """ ) " run login or return to login page if formpwd = logincode then Session(" LoginID" ) = formpwd else response .redirect(" login.asp?l=incorrect_login_or_password" ) End if " final redirect response .redirect(" post.asp" ) %>

The login uses session variables to store the login information, so to log off we simple abandon the session. The redirect appends the date to avoid seeing a "cached" login page after being logged out. This is not a security issue, but just for convenience.

<% session.abandon response .redirect(" post.asp?d=" & date ) %>

Now the main code is the post.asp page, this page is the same whether you are logged in as admin or just a guest visiting the page. If you are logeed in you see the same data as a guest, only you have more options available, you can delete posts, or restore deleted posts, or empty the "recycle bin" (where deleted posts are stored until you clear them out).

As you can see from the code below, we check for the loggedin session right from the start,
then we can use this throughout the rest of the script to display data based on your status as admin or guest.

<% option explicit %> <% LoggedIn = Session(" loginID" )

Once you are logged in you see more options available.

The file is split up into "parts" depending on what querystring is passed.

The section below checks to see if you are logged in and then check so see if
you have attempted to empty the "deleted" items from the database.

" ============Empty Deleted Items from the database============ If LoggedIn <> " " Then if request .querystring(" del" ) = 1 then Set dConn = Server .CreateObject (" ADODB.Connection" ) dConn.Open " & _ database_path mySQL = " DELETE FROM tblpost where active = 2;" dConn.execute(mySQL) dconn.close set dconn = nothing response .redirect(" post.asp" ) end if end if

As you can see from the rest of the main "post" code, different items are displayed or actions performed based on being logged in or not, and if so what querystring value you have passed to the page.

" ============set based on delete or undelete============ If LoggedIn <> " " Then showdeleted = request .querystring(" showdeleted" ) if showdeleted = 1 then active = 2 removetype = 1 delete_text = undelete_text delimage = " undelete.gif" else active = 1 removetype = 2 delete_text = delete_text delimage = " delete.gif" end if else active = 1 end if " ============Delete/Undelete Items from the guestbook display============ remove = request .querystring(" remove" ) if remove = 1 then Set dConn = Server .CreateObject (" ADODB.Connection" ) dConn.Open " PROVIDER=MICROSOFT.JET.OLEDB.4.0;DATA SOURCE=" & database_path removetype = request .querystring(" removetype" ) mySQL = " UPDATE tblPost SET Active = " & removetype & " WHERE ID = " & _ ID & " ;" response .write " updating" dConn.execute(mySQL) dConn.Close set dConn = Nothing response .redirect(" post.asp" ) end if " ============End Delete Section============ Set dataRS = Server .CreateObject (" ADODB.RecordSet" ) dataSQL = " Select TOP " & show_posts & " message, remote_addr, sysdate, " &_ " systime, id FROM tblPost WHERE active = " & active &_ " order by sysdate DESC, systime DESC;" " Response.Write dataSQL " response.end Set dConn = Server .CreateObject (" ADODB.Connection" ) dConn.Open " PROVIDER=MICROSOFT.JET.OLEDB.4.0;DATA SOURCE=" & database_path dataRS.Open dataSQL, dConn, 1 , 3 recordcount = dataRS.recordcount if recordcount > 0 then data = dataRS.GetRows() " Data is retrieved so close all connections dataRS.Close Set dataRS = Nothing dconn.close set dconn = nothing " Setup for array usage iRecFirst = LBound (data, 2 ) iRecLast = UBound (data, 2 ) end if " ============IF IS A POST BACK============ message = trim (request .form(" message" )) if request .form(" ispostback" ) = 1 AND (len (message) > minimum_length) then if allow_html = " no" then message = RemoveHTMLtags(message) else message = PreSubmit2(message) end if strSQL = " tblPost" " Open a recordset Set cRS2 = Server .CreateObject (" ADODB.recordset" ) Set dConn = Server .CreateObject (" ADODB.Connection" ) dConn.Open " PROVIDER=MICROSOFT.JET.OLEDB.4.0;DATA SOURCE=" &_ database_path cRS2.Open strSQL, dConn, 1 ,3 cRS2.AddNew cRS2(" message" ) = message cRS2(" sysdate" ) = date () cRS2(" systime" ) = time () cRS2(" remote_addr" ) = request .ServerVariables(" remote_addr" ) cRS2(" Active" ) = 1 cRS2.Update cRS2.Close Set cRS2 = Nothing dConn.Close Set dConn = Nothing response .redirect(" post.asp" ) end if " ============End POSTBACK Section============ %>
