Headers already sent by PHP
I finally got my first Mac Book yesterday. I like it , but one problem is really screwing with me . For some reason my project I transferred from my windows laptop isnt working properly. XAMPP starts up , I go to localhost/CI_BUHZ and the login page works as expected , I type in my credentials and hit enter, but then for some reason the whole thing gets stuck on my validate_credentials function in my login controller. it doesnt give me any errors , only 2 warnings - included below
Id like to note that: *This project works perfect on my old windows laptop i transferred it from. *Mod Rewrite is on to the best of my knowledge- if my my other controllers method calls such as CI_PROJECT/Login and CI_PROJECT/Feeds/Home are working right? *Even if i delete the validate_credentials function and recreate it with only this:
function validate_credentials()
{
redirect('site/home');
}
it still will not go from login -> site/home on my mac.
Here is the original validate credentials function :
function validate_credentials()
{
$this->load->model('membership_model');
$query = $this->membership_model->validate();
if($query) // if the user's credentials validated...
{
$uid = $this->membership_model->grab_uid();
$data = array(
'username' => $this->input->post('username'),
'uid' => $uid,
'is_logged_in' => true
);
$this->session->set_userdata($data);
redirect('site/home');
}
else // incorrect username or password
{
$this->index();
}
}
here is the .htaccess:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /CI_BUHZ/

Here's the img_model its complaining about ( even though the function being called doesn't require this model at all:
<?php
class Image_model extends CI_Model {
function get_images ($album_id, $uid){
$album_id =(int)$album_id;
$q = $this->db->query("SELECT image_id, album_id_fk, timestamp, ext, uid_fk FROM images WHERE album_id_fk = $album_id AND uid_fk = $uid");
if($q->num_rows() > 0) {
foreach($q->result() as $row) {
$data[] = $row;
}
return $data;
}
}
function image_check($image_id , $uid_fk){
$image_id = (int)$image_id;
$query = mysql_query("SELECT COUNT(image_id) FROM images WHERE image_id = $image_id AND $uid_fk");
return (mysql_result($query, 0)==1) ? true : false;
}
function delete_image($uid_fk, $image_id){
$image_id =(int)$image_id;
$image_query = mysql_query("SELECT album_id_fk , ext , uid_fk FROM images WHERE image_id = $image_id AND uid_fk = $uid_fk");
$image_result = mysql_fetch_assoc($image_query);
$album_id = $image_result['album_id_fk'];
$ext = $image_result['ext'];
$uid = $image_result['uid_fk'];
unlink('uploads/'.$uid.'_'.$album_id.'_'.$image_id.'.'.$ext);
unlink('uploads/thumbs/'.$uid.'_'.$album_id.'_'.$image_id.'.'.$ext);
mysql_query("DELETE FROM images WHERE image_id = $image_id AND uid_fk = $uid_fk");
}
}
?>

Make sure that nothing is outputted before you modify headers.
One very common reason for this error message is that there are newlines or other text after the closing PHP ?> tag. If there is only PHP in the file it is best not to use ?> at all (it is not mandatory, and not necessary either).
