Codeigniter: Image Upload

Question

I have a large form, and I just added an file input to allow users to upload an image.

Here's the new HTML:

<input type="file" name="file_1" />
<input type="text" name="image_description_1" class="text-input"/>

Here's the new _submit function:

if($this->CI->input->post('file_1')){
    $config['overwrite'] = TRUE;
    $config['allowed_types'] = 'jpg|jpeg|gif|png';
    $config['max_size'] = 2000;
    $config['upload_path'] = realpath(APPPATH . '../assets/uploads/avatars');

    $this->CI->load->library('upload', $config);
    $this->CI->upload->do_upload();

    $image_data = $this->CI->upload->data();

    $image['description'] = $this->CI->input->post('image_description_1');
    $image['user_id'] = $id;
    $image['image'] = $image_data['file_name'];

    $this->CI->db->insert('report_images',$image);

}

The description and user_id are correctly getting submitted, but the file is lost.

Should I be doing something different? Not really sure what's going wrong.

First of all don't get the do_upload() for granted, you have to validate the upload:

if ( ! $this->upload->do_upload('file_1'))
{
    // something went wrong, display errors
}   
else
{
    // everything is fine
}

Also, most likely it's your upload_path, check the document I linked to:

//You'll need a destination folder for your uploaded images. Create a folder at the root of your CodeIgniter installation called uploads and set its file permissions to 777.  
$config['upload_path'] = './uploads/';

So you may need to change your setting to something like:

$config['upload_path'] = './assets/uploads/avatars/';

Ahh! I'm getting 'you did not select a file to upload'...I've tried this with both `form_open` and `form_open_multipart`. Again, db values are getting entered, just no upload. Could it have to do with my filepath? – Kevin Brown Jan 13 '11 at 22:34

first of all **OF COURSE** you need to use `form_open_multipart`! also, where is your assets folder? outside the system folder? what is your folder structure? – ifaour Jan 13 '11 at 22:35
application, assets, and system are at the root. – Kevin Brown Jan 14 '11 at 19:00
@Kevin Brown: ok so, `$config['upload_path'] = './assets/uploads/avatars/';` should work? – ifaour Jan 14 '11 at 19:07

codeigniter expects your file input to be named userfile, unless you specify in your code like this,

$field_name = "some_field_name";
$this->upload->do_upload($field_name)

I changed my html `name="userfile"`. Still no luck. – Kevin Brown Jan 13 '11 at 20:06
can you add this to your code in place of `$this->CI->upload->do_upload()` 'if(!$this->CI->upload->do_upload()){$this->CI->upload->display_errors();}` – sea_1987 Jan 13 '11 at 20:14

Also you can initialize the config to set preferences.

$this->upload->initialize($config);

Make sure the name of the input file is set to "userfile" because the upload function expects the files coming from an input field whose name is set to "userfile"
