passing data from view to controller function?

view

Code:

<h1> Your Artifacts </h1>

&lt;link rel="stylesheet" type="text/css" href="css/button.css" title="Default"&gt;

&lt;?php foreach ($rows as $r): ?&gt;
                
&lt;?php echo anchor('site/click_artifact', $r->ArtifactID); ?&gt; |
&lt;?php echo $r->Description; ?&gt; |
&lt;?php echo $r->EnteredDate; ?&gt; |
<p class = "result"> &lt;?php echo anchor('site/delete_artifact'.$r->ArtifactID, "Delete Artifact"); ?&gt; </p>
<p class = "result"> &lt;?php echo anchor('site/modify_artifact'.$r->ArtifactID, "Modify Artifact"); ?&gt; </p>

      
&lt;?php echo "</br>"; ?&gt;

&lt;?php endforeach; ?&gt;

controller

Code:

function click_artifact($link){
              
              $this->members_area();
              $getLink = $link;
              $this->load->model('artifact_model');
              $data['rows'] = $this->artifact_model->display_artifact($getLink);
              $this->load->view('view_artifact', $data);
          }

I basically need the artifactID back from the view. what I want is that when a user clicks on the artifact id link it should get him the details related to that artifact id stored in the db.
