Hi,

What is the best way to pass variables from page to page (template to template) in Silverstripe?

I'm on a page which lists clients, and I want to click on the client and pass that client's name to a page whose controller takes the name and get all the projects for that particular client from the database.

The link is "projects-by-client?Client=Client1". In my ProjectsByClient controller, I have the following function:

function ProjectsByClient($Client) {
$whereStatement = "ProjectClient = '".$Client."'";
return DataObject::get("ProjectPage", $whereStatement);
}

Thwe query works fine if you hard-code a client name. But my controller is saying "missing argument" when I try to pass it in dynamically. How can I pass the client name to the controller?? Seems like this should be easy.

Thanks in advance,
Garrett

Hi,

Thanks so much for your reply. I am using your code ($Client = Director::urlParam('Client');) and am getting the follownig error:

Parse error: syntax error, unexpected T_VARIABLE, expecting T_FUNCTION in C:\wwwroot\wamp\www\silverstripe-v2.2.2\mysite\code\ProjectsByClient.php on line 26

Any ideas?

Thanks again,
Garrett

Hello again--

What do you mean by "using" Director:: in the controller? Do I need to instantiate that in some way, or...? And there is no other code in the controller, by the way-- if I take out the line you sent me the error goes away.

Thanks,
Garrett

Director::urlParam('Client'))?

I dont think thats correct as the default URL arrays is something like /Action/ID/OtherID. Also in the If you are using = rather then == so it will always return true, And since you are going to be inserting the URL parameter into a SQL query you need to make sure its safe! so what you would have is

and you would go mysite.com/home/client/Bob and it will list the projects where client = bob. The problem is that it doesnt work if you have spaces in the client name - as you are passing the name via the URL. So you might need to use the ID number of the client rather then the name.
