Cake: passing values to a function


Recommended Posts

I'm new to Cake (and using frameworks in general). I think I am having a syntax issue here. What I am trying to do is pass a value back to the function and then load a page based on the value passed:


Here's my controller:



    class BlogpostsController extends AppController { 
        var $name = "Blogposts";
        var $scaffold;
        function index() {
        function viewuser($userid) { 
            $this->set('thisuser', $this->User->find($userid));


In my cpt file I have this:


<td class="user"><?=$html->link($post['User']['name'], 'viewuser');?></td>


I know this won't work because I am not passing anything to viewuser, I get this error message:


Warning (2) <javascript:void(0);> : Missing argument 1 for viewuser() [APP/controllers/blogposts_controller.php, line 13]


Which is good, in a way. But if I rewrite it like this:


<td class="user"><?=$html->link($post['User']['name'], 'viewuser("1")');?></td>


I get another error:


Missing Method in BlogpostsController

Error: The action viewuser("1") is not defined in controller BlogpostsController


Which seems to be telling me I am not writing the syntax for passing values correctly...

This is happening because you probably haven't called the class as an object.


You'll need to call the class as an object first.

$bpControl = new BlogpostsController();


and then call the function within the class by doing something like this:


$userGet = $bpControl->viewuser("1");


That should solve the "method" error and all that. If you want to understand more about Objects, Classes and all that I provided a link, but here it is again: http://php.net/manual/en/language.oop5.php
