[eluser]fserrano[/eluser]
I am working locally. But here's the code.

project.php where I am having issues

Code:

<?php

class Project extends Controller {

    function Project()
    {
        parent::Controller();
        MY_getsubmenu();
        $this->load->helper(array('text','date'));
    }
    
    function index()
    {
        $this->load->view('project_view');
    }
    

    function view()
    {
        //Set default project to always remember the last project user was navigating
        if($this->uri->segment(3)!=NULL){
            $this->session->set_userdata('currentprojectid',$this->uri->segment(3));
            //Update user default project
            $this->db->where('id',$this->session->userdata('userid'));
            $this->db->update('users',array('defaultproject'=>$this->uri->segment(3)));
        } else {
            //Select default project from database
            //redirect('projects/$projectid/');
        }
        //Export data
        $data=array();
        $data['maincontent']="
             <h1>Title</h1>
             <fieldset>
                <legend>Log</legend>
                 <ul>
                 <li></li>
                 </ul>
                 <p>More...</p>
             </fieldset>
             <fieldset>
                <legend>Gallery</legend>
                 <ul>
                 <li></li>
                 </ul>
                 <p>More...</p>
             </fieldset>";
    
        //Get memos
        $data['activity']="<div id='memoslist'><fieldset><legend>Recent memos</legend><ul class='rollover'>";
        $this->db->order_by('date','desc');
        $this->db->limit(5);
        //If project is defined get memos in project only else get all memos in all projects
        if($this->uri->segment(4)){
            //$query=$this->db->get_where("memos",array('projectid'=>$this->session->userdata('currentprojectid')));
            $query=$this->db->get_where("memos",array('projectid'=>1));
        } else {
            $query=$this->db->get("memos");
        }
        foreach($query->result() as $row){
            //Project vars
            $submitterquery = $this->db->get_where('users',array('id'=>$row->userid));
            $submitternick = $submitterquery->row()->nickname;
            $datestring = "%M %d, %Y %h:%i %a";
            //$entrydate = mdate($datestring,strtotime($row->date));
            $entrydate = timespan(strtotime($row->date),time());
            $linkvalue=word_limiter(strip_tags($row->body),14)."<span><strong>$submitternick</strong> $entrydate ago</span>";
            $data['activity'].="<li><span class='icon'>".img('images/icon-memo.gif')."</span><span class='text'>".anchor("memo/view/".$row->id,$linkvalue)."</span><div class='clearleft'></div></li>";
        }
        //If project is defined get memos in project only
        $data['activity'].="</ul><p>More...</p></fieldset></div>";
        $data['activity'].=anchor('memo/form/'.$this->uri->segment(3),'Add one');
        $this->load->view('project_view',$data);
    }
