How to check the photo is selected when try to upload a photo - El Forum - 04-24-2012
[eluser]Zulkifli Said[/eluser]
hi,
i make a form to upload a text and a photo(* where optional to upload photo).
this my code in view:
Code:
<input type="text" name="firstname" />
<input type="file" name="userfile" id="file"/>THE QUESTION IS:
how i can check the user upload/browse/select a photo/file or not??
my code like on controller like this:
Code:
$data['name'] = $this->input->post('firstname',TRUE);
$data['photo'] = $this->input->post('userfile',TRUE);
if(!isset($data['photo'])){
echo "you not select a photo/file" ;
}else{
echo "you select a photo/file";
}But, i found the error...
if i not select a photo , the output is "you select a photo/file";
and if i select a photo , the output is "you select a photo/file";
i think the error is
1. $data['photo'] = $this->input->post('userfile',TRUE);
2. if(!isset($data['photo']))
please give me a solution.. thanks,,,

try using display_errors() function from the upload library
here is the snippet of code from user guide http://ellislab.com/codeigniter/user-guide/libraries/file_uploading.html
Code:
<?php
class Upload extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
}
function index()
{
$this->load->view('upload_form', array('error' => ' ' ));
}
function do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$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);
}
}
}

Your making a variable, $data['photo'], and assigning it the value of the post. Even if the post input (image) is empty, your variable $data['photo'] still exists!!!
Change to
[code]
if(!isset($data['photo']) || $data['photo'] == false){
...
}else{
...
}

no worries, at least you now know that you cant make a variable and then check isset() against it!!!
However, that may change in CI3, check this out: http://ellislab.com/forums/viewthread/215833/
But yeah, currently post variables return false if not set, when more than likely they should return null.
Try this just for your own knowledge:
Code:
$var = false;
if(isset($var)){
echo "here";
}else{
echo "not here";
}
//and now change $var = null; and see the difference.
