<li><?php echo $item;?>: <?php echo $value;?></li>
<?php endforeach; ?>
</ul>
<p><?php echo anchor('upload', 'Upload Another File!'); ?></p>
</body>
</html>
upload controller
Code:
<?php
class Upload extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
$this->load->model('create_thumb');
$this->create_thumb->function();
$this->load->model('postpa');
$this->postpa->function();
}
function index()
{
$this->load->view('upload_form',$data, array('error' => ' ' ));
}
function do_upload()
{
$images_location = "images/";
$thumbs_location = "images/thumbs/";
$allowed_types = 'gif|jpg|png';
$thumb_width = 100;
$maximum_size = 50000000;
$results = "Click to upload";
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}else
{
$data = array('upload_data' => $this->upload->data());
$this->load->view('upload_success', $data);
}
}
my model
Code:
<?php
class Create_thumb extends CI_Model{
function __construct()
{
parent::__construct();
}
function create_thumbnail($source,$destination,$thumb_width){
$size = getimagesize($source);
$width = $size[0];
$height = $size[1];
$x = 0;
$y = 0;
if($width> $height){
$x = ceil(($width - $height / 2);
$width = $height;
}elseif ($height> $width) {
$y = ceil(($height - $width / 2);
$height = $width;
}
$new_image = imagecreatetruecolor($thumb_width,$thumb_width)
or die('cannot install new gd image stream');
$extension = get_image_extension('$source');
if ($extension=='jpg' || $extension=='jpeg')
$image = imagecreatefromjpeg($source);
if ($extension=='gif')
$image = imagecreatefromgif($source);
if ($extension=='png')
$image = imagecreatefrompng($source);
imagecopyresampled($new_image,$image,0,0,$x,$y,$thumb_width,$thumb_width,$width,$height);
if ($extension=='jpg' || $extension=='jpeg')
imagejpeg($new_image,$destination);
if ($extension=='gif')
imagegif($new_image,$destination);
if ($extension=='png')
imagepng($new_image,$destination);
}
//get extensions
function get_image_extension($name){
$name = strtolower($name);
$i = strrpos($name,".");
if (!$i)( return ""; )
$l = strlen($name) - $i;
$extension = substr($name,$i+l,$l);
return $extension;
}//end get extendsion
function random_name($length){
$characters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890";
$name = "";
for ($i = 0; $i < $length;$i++){
$name .=$characters[mt_rand(0, strlen($characters) - 1)];
}
return "image-".$name;
}
}
my 2nd model
Code:
<?php
if($_POST){
if($_FILES['images']['name'] == ""){
$results = "Sorry but you forgot something!";
else{
$size=filesize($_FILES['image']['tmp_name']);
$filename = stripslashes($_FILES['image']['name']);
$extension = get_image_extension($filename);
if($size > $maximum_size){
$results="your file size is big";
}
else
if((extension != "jpg")&&
(extension != "jpeg")&&
(extension != "png")&&
(extension != "gif")) {
$results = 'wrong image type</center>';
}else{
$image_random_name= random_name(15),".",$extension;
$copy = @copy($_FILES['image']['tmp_name'], $images_location,$image_random_name);
if (!$copy){
$results = "Try useing a different image that hasnt already been posted on lulzlab";
}
else{
create_thumbnail($images_location,$image_random_name,$thumbs_location,$image_random_name,$thumb_width);
$results = "image has been uploaded"
}
}
