Hi Guys

I have a BIG problem with all my pages generated with CI.

I use HMVC and a layout class

In ALL my pages I get either -- or --- as the first charters in all pages witch is really annoying. I believe this is why my app can't run at my production server! See error message below

Quote:A PHP Error was encountered

Severity: Warning

Message: Cannot modify header information - headers already sent by (output started at /home/e-smith/files/ibays/ipcam/html/ci_1.7.2/codeigniter/CodeIgniter.php:1)

Filename: libraries/Session.php

Line Number: 662

Here is the first 2 lines of one of my pages

Code:
--

﻿﻿﻿<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

I don't know if it can be an encoding problem, but it seems like I have the same problem with both my development server and my production server!

Layout class:

Code:
&lt;?php  

if (!defined('BASEPATH')) exit('No direct script access allowed');

class Layout

{

    var $obj;

    var $layout;

    function Layout($layout = "layout_main")

    {

        $this->obj =& get_instance();

        $this->layout = $layout;

    }

    function setLayout($layout)

    {

      $this->layout = $layout;

    }

    function view($view, $data=null, $return=false)

    {    

        $loadedData = array();

        $loadedData['content_for_layout'] = $this->obj->load->view($view,$data,true);

        if($return)

        {

            $output = $this->obj->load->view($this->layout, $loadedData, true);

            return $output;

        }

        else

        {

            $this->obj->load->view($this->layout, $loadedData, false);

        }

    }

}

?&gt;

Hoping that someone can help me out!

Guess it's a whitespace problem. Take out the closing PHP tags, check on white spaces before opening tags.

Hi tomcode

Thank´s for your advice, i will try that. About the closing PHP tags, should they be removed in all files. If not. witch files?

[eluser]tomcode[/eluser]
You don't need them but they don't bother ... as long as You don't have a white space after them.

Hi tomcode

I've now removed ALL php closing tags from my project. It has removed almost all the weird charters. But still I have a few I just can't get rid off!!

Is there other things to check?

[eluser]tomcode[/eluser]
1. You need to check whether You have white spaces / line feeds BEFORE PHP opening tags at the beginning of files

2. Remember: everything outside an opening PHP tag will be sent to the browser

3. You mention now weird chars

Quote:... It has removed almost all the weird charters ...

What do You mean by that ?

Hi

Attached picture shows one of the places where the problem appears!

The code that generates this output is shown below.

Master View (from Layout library)

Code:
<div id="sidebar">&lt;?=modules::run('base/main_menu')?&gt;</div>

Controller base/main_menu

Code:
function main_menu()

    {

        $this->load->model('s_auth');

        $this->lang->load('main_menu');

        # Auth Menu

        $links = array(

        array('/auth/users', 'View Users'),

        array('/auth/create_user', 'New User'),

        array('/auth/roles', 'View Roles'),

        array('/auth/create_role', 'New Role')        

        );

        #$att = array('class' => 'submenu');    

        # END

        $data['menu'] ='<div class="sidebar_head">'.$this->lang->line('main_menu_users').'</div>';

        $data['menu'] .= $this->s_auth->menu($links);

        $this->load->view('orange/main_menu',$data);

    }

Sub View for main_menu

Code:
&lt;?=@$menu?&gt;

Maybe this file (main_menu.php) is UTF-8 encoded with BOM, some browsers can't deal with that.

Tried to encode all files to UTF-8 without BOM. But It still don't change anything!!

Is there a way to encode a dir including all subdirs?

I am Using WAMP on a winbox. Maybe the problem is there anywhere OR?
