"did not select a file to upload" when uploading using codeigniter

Question

im trying to upload an image but it always give me "You did not select a file to upload."

My controller

function add()
{

        $thedate=date('Y/n/j h:i:s');
        $replace = array(":"," ","/");
        $newname=str_ireplace($replace, "-", $thedate);

        $config['upload_path'] = './upload/';
        $config['allowed_types'] = 'gif|jpg|png|jpeg';
        $config['file_name']=$newname;
        $config['max_size'] = '100';
        $config['max_width']  = '1024';
        $config['max_height']  = '768';

        $this->load->library('upload', $config);
        //$this->upload->initialize($config);
        $this->load->library('form_validation');

        $this->form_validation->set_rules('title','title','trim|required');
        $this->form_validation->set_rules('description','Description','trim|required');
        $image1=$this->input->post('image');


     if ($this->form_validation->run()==FALSE){

            $this->addview();   

            return false;

        }


      if (!$this->upload->do_upload($image1)) {

        $error = array('error' => $this->upload->display_errors());
        $this->load->view('upload_error', $error);


         }

       else {
        $mage=$this->upload->do_upload($image1);

            $data =array(
            'title'=>$this->input->post('title'),
            'descrip'=>$this->input->post('description'),

            'image' => $mage['file_name']

    );  


            $this->load->model('member_functions');

            $q=$this->member_functions->insert($data);
    }}

all the file requirements and the file permissions are set but i still get the that eror. can someone please tell me what am i doing wrong

Solution 1

Parameter to $this->upload->do_upload() function should be the name of the form field. (If you call it without parameters userfile would be used). It seems in your case it should be 'image'. Instead of:

$image1=$this->input->post('image');

it should be:

$image1='image';

Solution 2

• View page

form tag should contain enctype="multipart/form-data".
ie, <form action='' method=''enctype="multipart/form-data> <input type='file' name='field_name'/>

• controller

and in controller upload code should be $this->upload->do_upload("field_name")
and jsut check whether file reaches in server side by making just print like

print_r($_FILES);

if you get null array then make sure that client side code is correct.

Solution 3

I totally agree with the advice about making sure the name of the file element in the form is either userfile or, if different, is passed to the do_upload method. However, for future reference it's also worth noting this line:

$image1=$this->input->post('image');

comes before

if (!$this->upload->do_upload($image1)) {

I found the post method of the input class does not return anything until after the do_upload method is called. Also, you've already called it in the if statement so you don't need to call it again in the else clause. After calling do_upload you now have access to form elements with $this->input->post and information about the uploaded file with $this->upload->data()

Solution 4

make sure you use

form_open_multipart()

if you are using the form helper.

Thanks alot for that... but now the image value doesn't pass file_name. i get "Column 'image' cannot be null". Is "'image' => $mage['file_name']" the correct way to pass the file name?

No i assumed that 'image' was the name of the form element. you should name the form element like: <input type="file" name="image" /> or if you want the default value for do_upload <input type="file" name="userfile" />
