Nested varibles?

robin 21 Jan 2010 14:48 question, complete

I have a Path.php varible called "lang" and it's value is "default".

I have a Low Variables called {template_branding} which contains....


< div id="branding" >
< h1 >< a href="{path=SITE_INDEX}" >{{lang}_sitename}< /a >< /h1 >
</ div >


I have another low variable called {default_sitename} with contains the name of my site.

{template_branding} output is....



< div id="branding" >
< h1 ><a href="http://mysite.org" >{default_sitename}< /a >< /h1 >
< /div >


Instead of....



< div id="branding" >
< h1 >< a href="http://mysite.org" >My Sitename< /a >< /h1 >
< /div >


I know it's a parsing order issue and i've been playing about with different orders but can't get anything to work. Is it possible?

   You're right, this is parsing order. Path.php variables are parsed first, then Low Variables with Early Parsing, then Low Variables without early parsing.
   
   However, you can swap the first two around:
   
   - Open ext.low_variables_ext.php in a text editor
   - On line #215, you'll see this:
   
   $IN->global_vars = array_merge($IN->global_vars, $early);
   
   - Change that to:
   
   $IN->global_vars = array_merge($early, $IN->global_vars);
   
   Now Low Variables with Early Parsing are parsed first, then Path.php vars.
   
   I'll do some checking to see if I can make this a setting of some sort.

   Great, that works!
   
   Thanks again low. I'll definitely be purchasing more of this module after i've completed my template.
   
   Thanks.
