Problem with <%if > control
7 June 2010 at 9:55am
This control block
<% if $URLSegment='edit' %>
$StudentEdit
<% else_if $URLSegment='add' %>
$StudentAdd
<% end_if %>is throwing this error.
Parse error: syntax error, unexpected '}' in C:\WINDOWS\Temp\silverstripe-cacheE--websites-_SilverStripe-Reception-Screen.v2.4.0\.cacheE..websites._SilverStripe.Reception-Screen.v2.4.0.themes.J2.templates.Layout.StudentEdit.ss on line 222
Yet went I use the %StudentEdit and $StudentAdd in the same template without the if control all is fine.
Any ideas anyone?

SS's templating language is very simple and doesn't allow for great amount of logic.
When doing comparisons, you don't need to use quote marks or apostrophes.
<% if URLSegment = edit %>
$StudentEdit
<% else_if URLSegment = add %>
$StudentAdd
<% end_if %>Personally, i would never compare URLSegments in the template as the site administrator will be able to change these, thus breaking the site.

I have the same problem with:
<% if $ClassName = HomePage %>
<% include Menu2 %>
<% end_if %> -

Sorry, also in the <% %> you must not use the $ before the variable name.
<% if ClassName = HomePage %>
<% include Menu2 %>
<% end_if %> -

<% if ClassName != ArticleHolder && ClassName != StaffHolder %>
<% include Menu2 %>
<% end_if %> -

Please check docs: http://doc.silverstripe.org/templates#if_blocks
No quotes around values, no $ before properties, only four simple boolean operators.
Hope it helps,

Of course i checked it before to didn't ask u stupid questions and it's logical that PHP property name always started with $ sign so it's not obvious and if u look at <% if Property != value &> here is strange sign & at the end of the row
and
if ( $Property && $Property)
it's the same as if ( $Property == TRUE && $Property == TRUE)don't be angry about my questions, just manual must be corrected and there won't such questions anymore
P.S. Sorry
