I am trying to upload single image using codeigniter. But getting error
"Undefined property: Main::$upload
Filename: controllers/Main.php
Line Number: 14"
This is my controller file "controller/Main.php"
<?php
class Main extends CI_Controller
{
public function index(){
$this->load->view('main_view', array('error' => ''));
}
public function upload(){
$config['upload_path'] = "./images/";
$config['allowed_types'] = 'jpg|png|gif';
$this->load->initialize('upload', $config);
if(!$this->upload->do_upload()){
$error = array('error' => $this->upload->display_errors());
$this->load->view('main_view', $error);
}
else {
$file_data = $this->upload->data();
$data['img'] = base_url().'/images/'.$file_data['file_name'];
$this->load->view('success_msg', $data);
}
}
}
?>
and this is my view file "views/main_view.php"
<!DOCTYPE html>
<html>
<head>
<title>Image</title>

<?php echo $error; ?>
<?php echo form_open_multipart('main/upload');?>
<input type="file" name="userfile" />
<input type="submit" name="Submit" value="upload image"/>
</form>
</body>
</html>
when image upload is successful I'm trying to show the image by this "view/success_msg.php"
<!DOCTYPE html>
<html>
<head>
<title>Image</title>
</head>
<body>
<h1>File has been uploaded.</h1>
<img src="<?php $img?>" width="300" height="300">
</body>
</html>
my image folder name is "images" and it is in the root directory. Please help my why I am having this error ?
Maybe the upload library isn't loaded. Change the first few lines ofpublic function upload() to the following
public function upload(){
$config['upload_path'] = "./images/";
$config['allowed_types'] = 'jpg|png|gif';
$this->load->library('upload', $config);
By sending $config to load->library you do not need to use initialize().
Controller
public function upload(){
$cc = $_FILES['userfile']['name'];
$extension = pathinfo($cc, PATHINFO_EXTENSION);
$newfile = preg_replace('/[^A-Za-z0-9]/', "", $_FILES["userfile"]['name']);
$config['file_name'] = time() . $newfile;
$ss = ".";
$picture1 = time() . $newfile . $ss . $extension;
$config['upload_path'] = "./images/";
$config['allowed_types'] = 'jpg|jpeg|png|gif|pdf';
$this->load->library('upload', $config);
if (!$this->upload->do_upload('userfile')) {
echo $this->upload->display_errors();
} else {
$this->load->view('success_msg', $picture1 );
}
}

Route::post('/getmsg','Hello#ajaxl');
When I click + or - the value doesn't change and no error.
Please any one help me
The problem is very small.
This line:
$("cart_quantity_input").val(data.qty);
just you forgot to add . before cart_quantity_input
So change it to be :
$(".cart_quantity_input").val(data.qty);

I found the answer to this, after a while of searching and reading uploadify manuals, it turns out if you use onUploadComplete, and you just upload one single fine, the method will never excecute, and it will keep waiting for more files, instead for one file only, you have to use onUploadSuccess, and read the data returned by it using file,data,response as parameters.

When the authentication fail:

When the authentication is correct:

But Firefox says that the Syntax is incorrect, could you help me?
I apologize for my bad english, I'm learning it...
i do not see any need of converting array to object for json_encode.
i will suggest using :
echo json_encode($data);
instead of :
echo json_encode((object)$data);
SOLVED! There was an "codification error", I have converted the PHP file from UTF-8 to UTF-8 Without BOM.
