I have already read like half a dozen similar questions here, and already double checked that there are no white spaces before <?php
or after ?>
in my library.
Ok note that I get this error RANDOMLY. When I am on the page and press CTRL+R (refresh) multiple times, for like 2 or 3 consecutive tries, the error message is not there, and then the error message comes and stays for a few more tries..
the exact error message I am getting is
<h4>A PHP Error was encountered</h4>
<p>Severity: Warning</p>
<p>Message: Cannot modify header information - headers already sent by (output started at A:\work\fast\semi 6\software engineering\project\project2\main\repo\main_proj\application\config\admin_template.php:2)</p>
<p>Filename: libraries/Session.php</p>
<p>Line Number: 672</p>
So obviously the culprit seems to be the admin_template.php library file..
my controller function that calls the library:
public function view_items(){
$this->session->set_userdata('f');
$table="F";
$this->admin_template->display_direct($table,'');
}
I am copying the file here
note that <?php
is at line 1
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Admin_template{
private
$selected_item=-1,
$menu=
array(
'Items'=>
array(
'Add Item'=>'admin/items/add_item',
'View Items'=>'admin/items/view_items',
),
'Administration'=>
array(
'View Admins'=>'admin/administration/view_admins',
'View Representatives'=>'admin/administration/view_representative'
)
);
public function __construct(){
foreach($this->menu as $key=>$items){
$this->menu[$key]['size']=sizeof($items);
}
$this->ci=&get_instance();
}
public function display_direct($view){
$admin_template_data=array();
$admin_template_data['content']=$view;
$admin_template_data['heading']="heading";
$admin_template_data['menu']=$this->menu;
$admin_template_data['selected_item']=1;//$this->get_selected_item();
return $this->ci->load->view('admin/main_template',$admin_template_data);
}
}
