POproblems with thumb creation
text
Body
copied!<p>I am currently using codeigniter 2.0 for a project and I have a little problem with thumb creation. I intend to allow users to upload picture and have the picture renamed to their last name then have anoda function from within the upload function create a thumbnail then send it to another directory inside the image directory (I named it avatar). The code does this perfectly, but now I intend to encrypt the last name before changing the uploaded pic name. That is where the problem sets in. The upload is carried out the name is changed but a thumbnail is not created ... please can any one tell me what the problem is here is the code sample</p> <pre><code>function set_avatar() { /*check if user is even logged in */ if($this->session->userdata('user_id')) { $last_name=$this->session->userdata('last_name');//this value is encrypted /*parse the useful user values to the data array for use on this page */ $data['user_id']= $user_id; $data['email']= $email; $data['last_name']= $last_name; $data['first_name']= $first_name; /*assign an empty value to the error key of the data array to avoid error on the view page*/ $data['error'] = ""; /*the directory for uploading the file the number represents a mixture of birth date and month af means all files u1 upload 1 avts avatar ..jst a path to make the path undetectable*/ $dir = "./path/avatar"; /*preparing the config settings for upload */ $config['file_name'] = $last_name; // the new file name the image should have $config['upload_path'] = $dir; // the directory the image should go to,already specified $config['allowed_types'] = 'gif|jpg|png'; // the file types that are allowed $config['max_size'] = '10000'; //the maximum image size $config['max_width'] = '300'; //the maximum image width $config['max_height'] = '230'; // the maximum image height $this->load->library('upload', $config); // retrieving the upload library with the specified settings /*using the do upload settings upload the file if it fails stop upload and show errors*/ if ( ! $this->upload->do_upload()) { $data['error'] = $this->upload->display_errors(); $this->load->view("user/set_avatar",$data); } /*else retrieve the upload data from the file uploaded*/ else { /*pass all the upload data to the $img_data array*/ $img_data = $this->upload->data(); /*the file(image) extension type png or gif or jpg*/ $img_ext = $img_data['file_ext']; /*thumb name without extension*/ $thumb = $last_name; /*thumb name with extension*/ $thumb_name = $thumb.$img_ext; /*create thumbnail using the thumb nail function*/ $this->create_thumb($thumb_name); /*record avatar details in the db*/ $avatar_array = array( "user_id" => $user_id, "avatar" => $thumb, "extension" => $img_ext ); $this->craft_set_user_details->set_avatar($avatar_array); /*start creat session for img_name and ext*/ $image_session = array( "img_name"=>$thumb, "img_ext"=>$img_ext ); $this->session->set_userdata($image_session); /*redirect to home page*/ redirect('home','location'); }//end if else $this->upload->do_upload }//end check if user is logged in ($this->session->userdata('user_id')) else { redirect("index"); }//end if eles user is logged in ($this->session->userdata('user_id')) }//end function set avatar /* this is the create_thumb() function */ ///start the create thumb function this is used in the set avatar function to create the avatar thumb function create_thumb($thumb_name) { /*check if user is logged in*/ if($this->session->userdata('user_id')) { //set the path to were the image is $dir = "./path/avatar"; //set the path to were the thumb should be sent $new = "./path/avatar/thumbs"; //set the configuration to be used for image resizing $config['image_library'] = 'gd2'; $config['source_image'] = $dir; $config['new_image'] = $new; $config['create_thumb'] = TRUE; $config['maintain_ratio'] = TRUE; $config['width'] = 35; $config['height'] = 50; //load the image library for image reszing $this->load->library('image_lib', $config); //resize image $this->image_lib->resize(); }//end if eles user is logged in ($this->session->userdata('user_id')) //else redirect to the home page else { redirect('index','location'); } }//end function to create </code></pre>
