block if inside tag

[simbo]

can a block expression go inside an <li here >
and can a function response be inside expression or does the whole function have to be in there.

this is the function to get page url:

<%
function curPageURL()
 dim s, protocol, port

 if Request.ServerVariables("HTTPS") = "on" then 
   s = "s"
 else 
   s = ""
 end if  
 
 protocol = strleft(LCase(Request.ServerVariables("SERVER_PROTOCOL")), "/") & s 

 if Request.ServerVariables("SERVER_PORT") = "80" then
   port = ""
 else
   port = ":" & Request.ServerVariables("SERVER_PORT")
 end if  

 curPageURL = protocol & "://" & Request.ServerVariables("SERVER_NAME") &_ 
              port & Request.ServerVariables("SCRIPT_NAME")
end function

function strLeft(str1,str2)
 strLeft = Left(str1,InStr(str1,str2)-1)
end function
%> 

responce

<%
  response.write(curPageURL())
%> 

what im trying to do is get the class of the <li> tag to become <li class="current"> to show current page in tabbed menu.
i have not begun to figure out how im going to express page url is equal to the a href inside the <li> tags yet, but i wanted to know if its poss to use blocks in this way..

Answer to both questions is probably "yes".

Make a simple test and see what happens. That's how most of us find out how Actinic works.

The PHP you've posted would only work if run on your server.

Most of the Actinic PHP tweaks posted on this Forum and AUG refer to running PHP code on the Actinic PC when the pages are being built. Code liek you've posted above wouldn't work there.

well chuffed this works

 <actinic:block if="%3cactinic%3avariable%20name%3d%22OuterBrochurePageID%22%20%2f%3e%20%20%20%21%3d%20%20%20%3cactinic%3avariable%20name%3d%22BrochurePageID%22%20%2f%3e" ><a class="nav" href="<actinic:variable name="BrochurePageURL" />"></actinic:block><span class=" 
<actinic:block php="true" >
$a=<actinic:variable name="BrochurePageID" />;
$b=<actinic:variable name="OuterBrochurePageID" />;
if ($a==$b)
  echo "actlarger2"; 
else
  echo "actlarger1"; 
</actinic:block>
"><actinic:variable name="BrochureName" /></span></a><span class="actlarger">&nbsp;|</span>

highlights the current broucher menu link.

just need 2 comparison variables for section pages and im in buisiness.

[NormanRouxel]

Watch out for spurious newlines. Best check the generated code. I think you'll have

<span class="
actlarger2
">

Also it's better to do

$a='<actinic:variable name="BrochurePageID" encoding="perl" selectable="false" />';

[simbo]

yes thats the case

seems to work fine live though at myactinic.co.uk, but taken on board and altering.

whats the reason for adding encoding="perl" selectable="false" to actinic variables in php scripts, is it pc to add that to every actinic variable used in php.

i have noticed you have pointed this out to other users aswell. are there cases where my code would not have worked unless encoding="perl" selectable="false" was added.

[NormanRouxel]

Use encoding="perl" if you intend to use Actinic variables within single quoted PHP strings (any embedded single quotes will be backslash escaped).

Use selectable="false" to prevent Actinic from adding extra unwanted code to these variables (that lets them interact with you) when in the design mode window.

Covered in detail in the Advanced Guide - Creating PHP Functions.

I use these nearly all the time when using variables in Actinic's PHP.

thanks norman

taken on board.
dont understand the first reason for adding encoding="perl", but dare say the penny will drop in time with more experience, php is a newly discovered tool for me and a very interesting and intuative one at that. looking forward to solving many future problems with php and blocks.

no good

my code creates a parse error, when broucher link is displayed on non broucher page, thus menu has no class applied.
i need to find a away to add in a check to see if the variable exists.

if
var exits
do
function
else
echo class="myclass"

[NormanRouxel]

See PHP manual for isset and / or read up on Actinic variable PageType.

maybe a bit round the houses

but i think this works, checks to see if brochure page, if so tests if page is current, apply class,
else if not brochure page apply class.

thanks for your pointers . pagetype was the one i needed.
