Problem with image manipulation (resizing)

[eluser]tommizzle[/eluser]
Hi all,

I'm currently having a problem with resizing an image using CI's image manipulation class. Here is my controller:

Code:

<?php

class Photo extends Controller {
    
    function _remap($username)
    {    
        
        $data = array();
        
        $this->load->helper('file');
        $this->load->library('image_lib');
        
        $data['userid'] = $this->Autoload_model->get_userid_from_username($username);
        $data['upload_success'] = false;
        $data['is_my_profile'] = false;
        
        if($this->input->post('upload_image')):
            
            $upload_image['file_name'] = $data['userid'];
            $upload_image['upload_path'] = './images/profile/';
            $upload_image['allowed_types'] = 'gif|jpg|png';
            $upload_image['max_width']  = '1024';
            $upload_image['max_height']  = '768';
            $upload_image['overwrite']  = TRUE;
            
            $this->load->library('upload', $upload_image);
        
            if ( ! $this->upload->do_upload()):
                $data['error'] = array('error' => $this->upload->display_errors());
            else:
                $data['upload_success'] = true;
            endif;
            
            $config['image_library'] = 'gd2';
            $config['source_image'] = './images/profile/' . $data['userid'] . '.jpg';
            $config['new_image'] = './images/profile/new_image.jpg';
            $config['create_thumb'] = TRUE;
            $config['maintain_ratio'] = TRUE;
            $config['width'] = 50;
            $config['height'] = 50;
            
            $this->load->library('image_lib', $config);
            
            if ( ! $this->image_lib->resize()):
                echo $this->image_lib->display_errors();
            else:
                echo 'Resize Success';
            endif;
            
        endif;
    
        
        
        if($this->input->post('delete_image')):
            unlink('./images/profile/' . $data['userid'] . '.jpg');
        endif;
        
        
        $data['has_photo'] = read_file('./images/profile/' . $data['userid'] . '.jpg');
        
        if($this->authlib->getUserName() == $username) $data['is_my_profile'] = true;
            
        $this->load->view('photo',$data);
    }

}
    
?>

and my view:

Code:

<?php
if(isset($error)) echo $error;

if($has_photo != false):
        echo '<img src="/images/profile/' . $userid . '.jpg" alt="My Profile Image" />';
else:
        echo '<img src="/images/profile/placeholder.png" alt="My Profile Image" />';
endif;

if($is_my_profile === true):
?&gt;
    &lt;form action="" method="post" enctype="multipart/form-data"&gt;
        &lt;input type="file" name="userfile" size="20" /&gt;
        &lt;input type="submit" name="upload_image" value="upload" /&gt;
        &lt;?php
        if($has_photo != false):
        ?&gt;
            &lt;input type="submit" name="delete_image" value="delete" /&gt;
        &lt;?php
        endif;
        ?&gt;
        
        
    &lt;/form&gt;
&lt;?php
endif;

if($upload_success === true) echo 'Success!';
?&gt;

The image is uploading, and then I'm even getting 'Resize Success', but it's not resizing or creating a new thumb in my chosen dir. I tried the normal 'GD' library too, and that didn't work either.

Has anybody got any ideas what's going wrong here? Any help would be appreciated

Thanks guys!

Tom
