access to variables inside a control
18 May 2010 at 11:50am
Hi I am new to silverstripe and using the image gallery module..
I am tweaking the templates but cant seem to access the $AlbumTitle variable to put inside the GalleryItems control..<h2>$AlbumTitle</h2>
<% control GalleryItems %>
// I want $AlbumTitle here
<% end_control %>I have tried using Parent.. I must be missing something?

Try $Top.AlbumTitle
<% control GalleryItems %>
$Top.AlbumTitle
<% end_control %> -

You can't directly access the parent if there is not existing relationship (has been the subject of proposals that have never quite made it to the code, see http://open.silverstripe.org/ticket/4751).
However in this case you should be able to:
<h2>$AlbumTitle</h2>
<% control GalleryItems %>
$Album.AlbumTitle
<% end_control %>Since ImageGalleryItem has an existing relationship to it's Album that you can traverse.

I don't think that's going to work because $Top will put you at the current controller, which is ImageGalleryPage.
Remember, ImageGalleryItem has a has_one 'Album', so keep it simple and use the relationship you're given
<% control GalleryItems %>
$Album.AlbumName
<% end_control %>As a matter of good practice, you should never modify core templates. You should override them in your theme dir. By modding the core code, you're making upgrades very difficult!

oops..
i been hacking away very happily
It worked using $Top... I had to use top.top as was inside another controll (getting the hang of this
<div style="background:#fff; width:591px;">
<% control GalleryItems %>
<% if First %>
<div id="image" style="background:#fff; height:470px; ">
<span class=""></span>
<% control Image %>$CroppedImage(591, 394)<% end_control %>
<div style="color:#181818;">+ You are viewing: $Top.Top.AlbumTitle</div>
</div>
<% end_if %>
<% end_control %>You should override them in your theme dir
Do I just add duplicates into the same folder my templates are in?
