asp_web_howto thread: dynamic path for include file


Message #1 by Roger Balliger <Roger@i...> on Fri, 29 Dec 2000 06:17:34 -0800
Here's what I'm trying to do:



I have a table.  The top cell is a header, the side is a nav, and the center

is the content cell.  I use server side include files to bring in styles,

navs and content.  What I need to do is be able to use a variable in the

path of the include file.  For example, '<!-- #include

virtual="/intratnet/manual/pages/<%=PageCheck%>xxcn.htm" -->'.  You can see

that the variable PageCheck is the first part of the file name which I would

like to change to bring in different content as needed. One way this

variable could be changed is by the user selecting a new item from a combo

box where the value is equal to the variable part of the filename.  I only

want to chage the contents of one cell dynamically by using a include file

which is dynamic. Can this be done?  If not, what are some other options?



What I have tried:



I am connecting to a dbase.  I tried to list the path in a dbase field and

bring it in as a value.  This caused errors with the label of the combo box

and was to long to be recognized by ASP.

I tried storing the include path in a variable and using response.write to

display it but the include command name was not processed as ASP since it

was written after the ASP was processed.  If the ASP processor were to make

2 passes over the code, then it would be caught, but ASP doesn't work that

way.



I am contemplating using frames and storing the path for the new source cell

in a dbase field and then storing that as a value for the combo box to be

used as the new frame source when an item is selected.



Any suggestions will be greatly appreciated.  I know there must be an

efficient way to change content in a cell based on user selections without

using frames.  Amazon and search engines do this.



Thanks for any help.

Hi,

First of all, you must know that "#include" is processed BEFORE ASP, so you

can not include a file dinamically. The only way to do this is including N

files and with an "If statement" show the result to the user:



<% If var_a = "1" Then %>

	<!-- #include... >

<% Else If %>

	<!-- #include... >

<% End If %>



...but this does not work when you have to include many files... so the

second option is to include the file you want (html in your case) with a

FileSystem Object... so you just "read" thye file and show the contents:



<%

Dim fso

Set fso = CreateObject("Scripting.FileSystemObject")

path = Server.MapPath("/") 'this returns the path of your web site

path = path & "\folder_name\" & file_name & ".html""



'shows the file

If fso.FileExists(path) Then

	Set ThisFile = fso.OpenTextFile(path_aviso,1,FALSE,FALSE)

	Do While ThisFile.AtEndOfStream <> True

		Response.Write (UCase(ThisFile.ReadLine) & "<br>" & Chr(13)

& Chr(10))

	Loop

	ThisFile.close

	Set ThisFile = Nothing

Else

	'the file does not exist!

End If



Set fso = Nothing

%>





Hope that helps,

Happy Holydays!

Thanks.  I'll give it a try.



In the mean time, I'm assuming the variable 'file_name' will be my variable

who's value I can change to modify the path name of the file I want to open.



Also, are you sure this will work to display the file contents within a

table cell (just as an include file would)?



Thanks again Vladimir.

Consider using the database as the repository for the actual content instead

of the path. A batch tool coded in asp can open all the files in a folder

and add them as table entries to create this library. This gives you the

actual content delivered by the database to the page instead of using the

file system. Also, the content is easier to update, roll-back, etc. because

it's in a db.



A hassle with doing this for html or coding is converting the special

characters when adding content to the db, you need a conversion subroutine.

Other than that, I find it an easy way to get the functionality of dynamic

includes and better control over the content.

That is a great idea.  I think the content woould be too large though.  Each

content file is approximately the size a 2-page word doc (converted to HTML)

with table formatting and XML (thanks to Word2K).  Do you think it would

still work? Or even be worth trying?  I'm thinking the fileSystemObject may

be the best route.

Short answer is yes, just like an include. But.



Forgot about ASP3.0 having dealt with this, you can use the server.execute

method instead for each if condition ...if (?) then

server.execute("file_name")... That would give you another way to do it

dynamically without having to convert the files so is a better idea.



I just like using the database for include type global coding snippets,

functions and whatever. In a dev environment this puts the include library

into a database where you can actually find something by searching the

content yourself with query analyzer.



Anyway, if this appeals, what you do is create an asp page that opens the

existing include files, copies them as a string which is \'parsed for

special characters\' (single quotes etc. need a backslash) into varchars.

This converts the actual file into a field in a database table where the key

field name is your unique "file_name" and this second field with the actual

contents.



When you need that include, you run a query with a where clause and the

recordset object ...rsInput("file_contents")... returns what was formerly in

a file and then you response.write it where you need it. If these are bigger

than 8,000 you have to parse them into packages and concatenate them back so

that's when I would use server.execute for sure.
