Hey Everybody. I just had some issues since I'm still learning SilverStripe templating, and I figure there're a few others like me. So, this is a brief write-up of what I've learned. Maybe it'll help a few others out there?
IF Statements that were based on the page/Widget's $Title variable:
First of all, two requirements of the template needed me to hide some Widget titles, but show the titles on other pages.
Though it's a bit messy, I realize that some (if not all) Widgets have default titles.
Since I was using the Custom HTML Widget, I put the following code into my template's custom WidgetArea.ss :
<% if Title = Info %> <% else %> $Title <% end_if %>
Since I was so used to PHP, I was expecting the IF statement to require a $ before Title, or quotes around "Info" to signify that it was a string. Since SilverStripe somehow managed to figure this out itself, I was good.
Altering CSS/HTML Based on Widgets a page may Possess:
This new template may have pages that have no side bar-- and if there is no side bar, I needed the HTML to be altered to pertain to the CSS. In my case, I wanted to alter/add Classes to a div tag.
Desired Page code without widgets:
Desired Page code WITH Widgets:
<div id="container" class="sidebar">
Here is the code I tried:
<% control Widgets %>a <% if TotalItems %>class="sidebar"<% else %> <% end_if %> b <% end_control %>
This won't work because I am not controlling the right thing--. <% control Sidebar %> worked out. See the revised, working code below:
class="<% control Sidebar %><% if Widgets.TotalItems %>sidebar<% else %><% end_if %><% end_control %>
I managed to accomplish the above when remembering that controls/IF statements didn't want the $ sign, and when I realized that Widgets were the children of the Sidebar item.
I realize that some of this may seem pretty easy to an experienced SilverStripe coder, but I wanted to put the word out there.
Let me know if this helps you! 8)
