Control Inside Control?
14 October 2009 at 10:28am
Hi,
I've run into this problem again and again and again-- I'm controlling a DataObject::get() resultset, and while in that loop I need to get an ID each time and pass that into another function to get some data from an associated table to get some other stuff. Why can I not do this?
function Clients($limit=5) {
$start = isset($_GET['start']) ? (int) $_GET['start'] : 0;
if($limit==5)
return DataObject::get("ClientPage", "", 'Sort ASC', "", "$start,$limit");
else
return DataObject::get("ClientPage", "", 'Sort ASC', "", $limit);
}In the template:
<% control Clients %>
<li>
<% if ClientLogo %>$ClientLogo.SetWidth(100)<% end_if %>
<% if ClientURL %><a href="$ClientURL" target="_blank"><% end_if %><h4>$ClientName</h4><% if ClientURL %></a><% end_if %>
<% if ClientHeadline %><h6>$ClientHeadline</h6><% end_if %><% control Testimonials(ClientID) %>
Blah blah blah
<% end_control %>
</li>
<% end_control %>This is on a Holder page. I need to display all the properties of the child pages, PLUS several rows of other data that BELONG to each of these pages that is stored in another table (using DataObjectManager). How else am I going to do this without knowing what ID I'm on in the loop? I can't put the Clients() function in the ClientPage class because I need to control it on the Holder page.
Any advice on this would help a lot, because I have run into this issue on more than once occasion.
Thanks,

You can't pass a $Var variable into a control or any statement in SS. It has to be a static value eg 150 or 'Test'. In your case how you would do this is on the Client dataobject have a function
// Client Dataobject
function Testimonials() {
return DataObject::get('Testimonials', "ClientID = '$this->ID'");
}then in your template you can do
<% control Clients %>
$Title
// etc
<% control Testimonials %><% end_control %>
<% end_control %> -

Hi thanks for your reply @willr.
What you described is already what I am doing. I already DO have the Testimonials function in the ClientPage class:
...
class ClientPage_Controller extends Page_Controller {
function Testimonials() {
return DataObject::get("Testimonial", "ClientPageID = $this->ID", 'Sort ASC', "", null);
}
}The problem in this case is that the ClientPage is not a DataObject. The ClientPage class extends Page. These are Pages. Again, in the Holder template, I am controlling the ClientPages. How do I get these ID's and pass them into the Testimonial table to get these rows?? As you can infer from the above code, the Testimonial table is a DataObjectManager table whose rows are associated with a ClientPage based on a ClientPageID. But it doesn't work. When I put the nested Testimonial control in the template as follows:
<% control Clients %>
<li>
<% if ClientLogo %>$ClientLogo.SetWidth(100)<% end_if %>
<% if ClientURL %><a href="$ClientURL" target="_blank"><% end_if %><h4>$ClientName</h4><% if ClientURL %></a><% end_if %>
<% if ClientHeadline %><h6>$ClientHeadline</h6><% end_if %>
<% control Testimonials %>
$TestimonialQuote<br />
<% end_control %>
</li>
<% end_control %>I get:
Website Error
There has been an errorThe website server has not been able to respond to your request.
What am I doing wrong here?
Thanks again,

Never mind, @willr! I don't know what was wrong, but this code I had IS in fact working. I guess my browser was cached or something. Anyways, thanks so much for the help, as always!

Website Error
There has been an errorFYI it might help when you are developing to put the site into development mode by adding Director::set_environment_type("dev"); in your _config file.
Glad you got it sorted though.

"The problem in this case is that the ClientPage is not a DataObject"
Just an FYI: ClientPage extends Page extends SiteTree extends DataObject.. so Pages are definitely DataObjects =)
