Has else_if been removed from the template language?
4 August 2009 at 4:57am
I found an old post about control structures in templates that states that else_if should work but when I try to use it in my templates it just gets printed as raw text.
I tried doing something like this
<% if Level(2) %>
$Parent.Title
<% else_if Level(3) %>
$Title
<% else %>
$Title
<% end_if %>
But I get the else_if back in raw text. -

I'm having the same problem, does else_if work or not? What's the deal with it just coming out as plain text? My code is:
<% if InSection(home) %>
home
<% else_if InSection(about) %>
about
<% else %>
subpage
<% end_if %> -

Did this ever get answered? I have the same problem, see here: http://www.silverstripe.org/all-other-modules/show/293853?showPost=293853

I'd raise this as a bug as I've seen it too!
But it is soooo simple to fix that I hadn't bothered...
<% if InSection(home) %>
home
<% else %>
<% if InSection(about) %>
about
<% else %>
subpage
<% end_if %>
<% end_if %> -

@Swaiba
That's all well and good if you only have 3 cases. Unfortunately I have about 8 which leads to a very messy set of nested conditionals which goes something like this:
<% if InSection(home) %>
home
<% else %>
<% if InSection(about) %>
about
<% else %>
<% if yyyyyyyyyyyyyyyyyyyy %>
subpage
<% else %>
<% if xxxxxxxxxxxxxx %>
something else
<% else %>
<% if zzzzzzzzzzzzzzzzz %>
something else
<% else %>
something else
<% end_if %>
<% end_if %>
<% end_if %>
<% end_if %>
<% end_if %>And that's the simplified version(!)
So, does anyone know, has "else_if" actually been removed???

Oh Absolutely Junglefish!
As I said "I have noticed else_if not working as well" and if you want to get an official response then it is always easier to go to http://open.silverstripe.org/ and raise a ticket!
IMHO if you have such a large complex if / else if I'd think it was too complex and try and achieve it slightly differently using different page types, includes or involving the controller a little more. Or you could do the following...
<% if InSection(home) %>
home
<% end_if %>
<% if InSection(about) %>
about
<% end_if %>
<% if yyyyyyyyyyyyyyyyyyyy %>
subpage
<% end_if %>
etc..or without the formating if you have a small amount of code inside each if (and if not, perhaps including templates might help)...
<% if InSection(home) %>home<% end_if %>
<% if InSection(about) %>about<% end_if %>
<% if yyyyyyyyyyyyyyyyyyyy %>subpage<% end_if %>
etc..And yes that also has some flaws... Personally I'd recommend trying to do this work without such a large/complex logic in the template. There are many other ways to do things in silverstripe, as yet another suggestion you could extend page to add to the $db a field MyCustomText and then for each of these page types you can edit the text in the cms and then you only need $MyCustomText in the template.
Just to make it clear I agree that else_if is buggy, but I am also suggesting that there are other, perhaps better ways, to get the same result.

<% else_if %> has not been removed, it just doesn't accept as much options as <% if %> does. The valid ways of using <% else_if %> are:
- <% else_if Val %>
- <% else_if Val1 || Val2 %>
- <% else_if Val1 && Val2 %>
- <% else_if Val1 == Val2 %>
- <% else_if Val1 != Val2 %>
- <% else_if Obj.Val %>
- <% else_if Obj.Meth.Val %>
- <% else_if Val %>
