I am using codeigniter 2.2.6 for my server (I am a newbie in CI), when I tried to make the upload file demo work, but nothing happened when I clicked on the submit button.

Here is the user guide that I followed:

http://www.codeigniter.com/userguide2/li...ading.html

the view file:

PHP Code:
    <html>
    <head>
    <title>Upload Form</title>
    </head>
    <body>
    
    <?php echo $error;?>
    
    <?php echo form_open_multipart('upload/do_upload');?>
    
    <input type="file" name="userfile" size="20" />
    
    <br /><br />
    
    <input type="submit" value="upload" />
    
    </form>
    
    </body>
    </html> 

the controller:

PHP Code:
    <?php
    class Upload extends CI_Controller {
        function __construct() {
            parent::__construct ();
            $this->load->helper ( array (
                    'form',
                    'url' 
            ) );
        }
        function index() {
            echo CI_VERSION;
            
            $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 );
            
            echo "step 1";
            
            if (! $this->upload->do_upload ()) {
                echo "step 2";
                
                $error = array (
                        'error' => $this->upload->display_errors () 
                );
                
                $this->load->view ( 'upload_form', $error );
            } else {
                echo "step 3";
                    
                $data = array (
                        'upload_data' => $this->upload->data () 
                );
                
                $this->load->view ( 'upload_success', $data );
            }
        }
    }
    ?>

I can see the browse and submit button, after I select a file, the file name is correctly displayed but when I click on submit, nothing happens, it looks like that the submit click is not handled.

As you can see, I set 3 echo "step ." to follow the flow, but none of them get printed, I don't know why.

Could anyone help? please explain me the logic behind that button click handling.

Add public in front of your function. Public function foo.

Keep calm.

thanks for your reply.
I added public, but still the same things, function do_upload is not called at all.

I guess the following code has some pbs:

<?php echo form_open_multipart('upload/do_upload');?>

the function do_upload is not called at all, how should it be used?

seaguest · 03-19-2016, 07:32 AM

OK, I found the problem, apparently there is a problem of
<?php echo form_open_multipart('upload/do_upload');?>

It generate this wrong url:
<form enctype="multipart/form-data" accept-charset="utf-8" method="post" action="http://::1/upload/do_upload">
<input type="file" size="20" name="userfile">
<br>
<br>
<input type="submit" value="upload">
</form>

I changed the action="http://::1/upload/do_upload" to action="http://localhost/upload/do_upload" and it works.

Could anyone explain why
<?php echo form_open_multipart('upload/do_upload');?>
generates the wrong url?

You probably left the $config['base_url'] setting blank (in application/config/config.php). Then, CI is best-guessing it. I think your hosts file (in Windows/System32/Drivers/Etc) there is no reference to localhost, but only to ::1.
The easiest way to solve the problem is assigning the right value to $config['base_url']. In your case:

PHP Code:
$config['base_url'] = 'http://localhost/';

Indeed it is empty, because I have removed the index.php in the url path.

index.php in your URIs has nothing to do with the base_url setting.
Also, upgrade to the latest 3.0.x version, now - you wouldn't have this problem with it.

2.x is unsupported, there's no point in trying to teach yourself in it.
