Question

Hi this is a simple question, however I have now stared at it long enough to realise im simply not seeing the error. If anyone can see where this is going wrong I would be very thankful.

public function create()
{
$this->load->model('ticket_model');

if($_POST)
    {
    // validate form
    if($this->_validate())
        {

$this->load->view('sidebar/service',$head_data);
$this->load->view('ticket/create',$body_data);
$this->load->view('foot',$foot_data);
return;
}

This is my code, and everything is going well, except for the section where i save the upload, as nothing seems to be firing the model, even thought there is a file being posted from the from submit and there for the filename being posted is != ''...... e.g

if ($_FILES['filename']['name'] != '')
{
    //set variables for save
    $_POST['file_path'] = $temp_file_location;
    $_POST['file_name'] = $thisFileHumanName;

    $_POST['file_size'] = $thisFileSize;
    $_POST['file_type'] = $thisFileType;
    $_POST['messageId'] = $thisMessageId;

    $this->ticket_model->save_upload($_POST);
}

my apologies if this is silly mistake.

Answer 1

Why are you doing it this way? Codeigniter has a built in class for uploading files. You also should be using the input class instead of $_POST. It will make it a lot easier!

As for your code. You're actually setting the $_POST variable and trying to use that in save_ticket. You can't do that.

The predefined $_POST variable is used to collect values from a form sent with method="post"

You're trying to use it the other way around.

So to make it work, change the $_POST into $something and it should work, but it's still not the way to go.

//set variables for save
$something['file_path'] = $temp_file_location;
$something['file_name'] = $thisFileHumanName;

$something['file_size'] = $thisFileSize;
$something['file_type'] = $thisFileType;
$something['messageId'] = $thisMessageId;

$this->ticket_model->save_upload($something);
