How do I rewrite the following PHP code in Classic ASP?
<head></head>
<body>
<h1>Test</h1>
<section><?php echo include('content/'.$_GET['p'].'.php') ?></section></body>
If the url is http://foo.bar.com/admin.php?p=pages, then content/pages.php is shown.
You can't do this with INCLUDE but you could use Server.Transfer instead, eg.
Server.Transfer "content/" & Request.Form("p") & ".asp"
Never trust what comes from the clientside (browser) as they can try to hack you.
Since it is not likely that "shdyhio3hlkehio.asp" or similar is a proper file, you should limit the options to your actual selection and also have a default file which is a "catch all other requests".
Combine that with Server Side Includes and you have your setup ready.
You should also check if the user actually requested a page -- if "p" is empty then show a default message.
Note the use of LCase in the "Select Case"-line and lowercase values in the Case-lines.
This is due to the face that the string comparison is case-sensitive, meaning "about" (lowercase "a") and "About" (uppercase "A") is not the same.
Eksemple:
<% If Request.QueryString("p") = "" Then %>
no specific page was request, show a default message
<% Else %>
<% Select Case LCase(Request.QueryString("p")) %>
<% Case "content" %><!-- #include file="content.asp" -->
<% Case "about" %><!-- #include file="about.asp" -->
<% Case "contact" %><!-- #include file="contact.asp" -->
<% Case Else %><!-- #include file="404.asp" -->
<% End Select %>
<% End If %>
You can use something like this
<!--#include file="somefile.asp"-->
in your HTML file .

What happens if I include 2 pages conditionally?
<% if(x==1) {%>
<!-- #Include virtual="/ws/inc/Master1.inc" -->
<% } else { %>
<!-- #Include virtual="/ws/inc/Master2.inc" -->
<% } %>
Which command runs first? Are both included at first, and then the if clause is evaluated, or will just one of them be included?
I want to be sure not to include the wrong page at all.
It depends on the condition. If you don't have the statement inside a loop where you iterate through x or something similar, I think only one page will be included depending on the value of x
I am new to classic ASP and I am trying to create a Master Page with variable placeholders and fill the information on that page with variables that are worked on a content page.
my master page looks like this:
<html>
<head>
<title>Template Loaded Properly</title>
</head>
<body>
<% call BodyContent %>
<span>Title: <% //place title here %></span>
<span>Content: <% //place content here %></span>
</body>
</html>
and the content page like this:
<!--#include virtual="/templates/TEMPLATE.html" -->
<% sub BodyContent %>
var Title = "This is the title"
var Content = "Here goes some content"
<% end sub %>
Any help will be appreciated.
Once you include the page with the variables, you can treat them as if they were created right then and there (because in a sense they are created right then and there, at least from the server's point of view). You do need to make the variables global in scope [read: dim them outside the sub], unless you want to list all of them when calling your BodyContent sub. (Personally, I don't see the point, but some people are unreasonably allergic to global variables.)
<%
dim Title, Content
sub BodyContent
Title = "This is the title"
Content = "Here goes some content"
end sub
%>
<body>
<% call BodyContent %>
<span>Title: <%=Title%></span>
<span>Content: <%=Content%></span>
</body>
One caveat, though: include files are processed long before the code, so you can't vary what file is included. In other words, don't do this:
<%If x = a Then%>
<!-- #include virtual="/templateA.inc" -->
<%Else%>
<!-- #include virtual="/templateB.inc" -->
<%End If%>
The result of trying something like that is that both templateA and templateB will be included. If you need conditional includes, look into using FileSystemObject to read the content of the appropriate template, and then using Execute to, well, execute it.
can anyone see why using this code:
<% select case edit
case "specs" %>
<!-- #include file="edits/specs.asp" -->
<% case "desc" 'LINE 28 HERE %>
<!-- #include file="edits/desc.asp" -->
<% case "review" %>
<!-- #include file="edits/review.asp" -->
<% case "images" %>
<!-- #include file="edits/images.asp" -->
<% case "floor" %>
<!-- #include file="edits/floor.asp" -->
<% case else %>
<!-- #include file="edits/main.asp" -->
<% end select %>
is creating this error:
Microsoft VBScript compilation error '800a0400'
Expected statement
/*****.com/edit2.asp, line 28
case "desc"
^
Because it seems ok to me and the blogs I've found about it, (asp isn't exactly my best language though)
<%
select case edit
case "specs"
call server.execute("edits/specs.asp")
case "desc"
call server.execute("edits/desc.asp")
case "review"
call server.execute("edits/review.asp")
case "images"
call server.execute("edits/images.asp")
case "floor"
call server.execute("edits/floor.asp")
case else
call server.execute("edits/main.asp")
end select
%>
I'm having difficulties google what's the difference between the following script tags:
<%# ... %>
<% = ... %>
<% ... %>
Can someone help?
These tags also may be ASP.NET tags.
Here are links with the information about each tag:
<%# ... %> Data-Binding Expression Syntax
<%= ... %> Displaying from ASP.NET
<% ... %> Embedded Code Blocks in ASP.NET Web Pages
i don't know about the 1st one
but 2 and 3 was the jsp tag,
2 one is the expression tag like when you want to get value from jsp variable then you can use this tag
for e.g.
String arg = "Pratik"
now you want use this in jsp page anywhere
Hello <%= name %> ////// it will print on web page as Hello Pratik
the 3rd one is the script tag
when you want write block of jsp,java code you can write within this tag
for ex.
<%
String name="";
name = "abc";
out.println(name);
%>
Is there a way to include a VBScript page into an ASP page written using Javascript?
There is an ASP page written in Javascript, but our sidebar menu is written in VBScript. When I include the sidebar asp file into the Javascript the server gives an error.
< %# LANGUAGE="JavaScript" %>
<%
...
< !--#include file="sidebar.asp"-->
...
where sidebar.asp is written using VBScript.
You can try this, but my guess is that the sidebar.asp will be executed before your Javascript code.
< %# LANGUAGE="JavaScript" %>
<%
...
<script language="VBscript" runat=server>
< !--#include file="sidebar.asp"-->
</script>
...
I do this all the time, but I write my ASP/JScript pages a bit differently. Instead of switching the page language to "JavaScript", I leave it at the default "VBScript" and then use a <SCRIPT LANGUAGE="JavaScript" RUNAT="Server"> block for my JScript code. The JavaScript SCRIPT blocks are executed before the normal <% %> tags, so I do all my page processing in the SCRIPT blocks and then simply plug the results into the page with <% %> tags. Here's an example:
mainpage.asp:
<SCRIPT LANGUAGE="JavaScript" RUNAT="Server">
var name;
var address;
var phone;
function main() {
var rec = go_to_database();
name = rec.first_name + " " + rec.last_name;
address = rec.address;
phone = rec.phone;
}
</SCRIPT><% main() %>
<html><head><title><%= name %></title></head><body>
<p>Name: <%= name %><br/>
Address: <%= address %><br/>
Phone Number: <%= phone %></p>
<!--#include file="subpage.asp"-->
</body></html>
subpage.asp:
<p>Blah blah blah, some random VBScript code: <%
Dim whatever
whatever = some_silly_thing()
Response.Write(whatever)
%>.</p>
So, first IIS processes the SSI and includes subpage.asp into mainpage.asp. Then, it evaluates the JScript SCRIPT block, declaring the variables name, address, and phone and defining the function main.
Then it evaluates each <% %> tag in order. <% main() %> call the main function and sets values for name, address, and phone. Then <%= name %>, <%= address %>, and <%= phone %> substitute those values into the page. Finally, the <% %> code from subpage.asp is evaluated and the Response.Write value ends up in the page output.
While the whole page is not written in JScript, the vast majority of the code can be, inside the SCRIPT block. Would that work for you?
