I am trying to upload multiple images and I have a jquery plugin set up so I can browse for multiple files and select them.
The only problem I am having is accessing the file array in my controller, does anyone know how I can do this? Thanks.
view:
<input type="file" name="userfile[]" id="userfile" class="multi" />
I had this same issue on a project last year, after a bit of searching I found a perfect function.
I take no credit it for it, but cannot remmeber where I found it so if anyone knows please link back to the author.
Make sure the form has the files named like this
<input type="file" name="userfile"/>
<input type="file" name="userfile2" />
<input type="file" name="userfile3" /> ..etc
Or
<input type="file" name="userfile[]" />
The function..
function multiple_upload($upload_dir = 'uploads', $config = array())
{
$files = array();
if(empty($config))
{
$config['upload_path'] = '../path/to/file';
$config['allowed_types'] = 'gif|jpg|jpeg|jpe|png';
$config['max_size'] = '800000000';
}
$this->load->library('upload', $config);
$errors = FALSE;
foreach($_FILES as $key => $value)
{
if( ! empty($value['name']))
{
if( ! $this->upload->do_upload($key))
{
$data['upload_message'] = $this->upload->display_errors(ERR_OPEN, ERR_CLOSE); // ERR_OPEN and ERR_CLOSE are error delimiters defined in a config file
$this->load->vars($data);
$errors = TRUE;
}
else
{
// Build a file array from all uploaded files
$files[] = $this->upload->data();
}
}
}
// There was errors, we have to delete the uploaded files
if($errors)
{
foreach($files as $key => $file)
{
@unlink($file['full_path']);
}
}
elseif(empty($files) AND empty($data['upload_message']))
{
$this->lang->load('upload');
$data['upload_message'] = ERR_OPEN.$this->lang->line('upload_no_file_selected').ERR_CLOSE;
$this->load->vars($data);
}
else
{
return $files;
}
}
Now it's been a while since I've used it so if you need any extra help setting it up just let me know.
<input type="file" name="userfile[]"/>. This "solution" is an actual workaround. But I must aprove that this solution is one of the best.
To use Jquery multiple upload using html elements array [] developed as follows in the act of receiving data sobrescrevi the global variable $ _FILES PHP so that the function do_upload could read later. see:
#copy the original array;
$temp_array;
foreach($_FILES['fil_arquivo'] as $key => $val)
{
$i = 0;
foreach($val as $new_key)
{
$temp_array[$i][$key] = $new_key;
$i++;
}
//
}
$i = 0;
foreach($temp_array as $key => $val)
{
$_FILES['file'.$i] = $val;
$i++;
}
#clear the original array;
unset($_FILES['fil_arquivo']);
$upload_path = 'media/arquivos';
$config['upload_path'] = $upload_path;
$config['allowed_types'] = 'doc|docx|xls|xlsx|ppt|pptx|pdf|txt|jpg|png|jpeg|bmp|gif|avi|flv|mpg|wmv|mp3|wma|wav|zip|rar';
$config['encrypt_name'] = true;
$this->upload->initialize($config);
foreach($_FILES as $key => $value)
{
if( ! empty($value['name']))
{
if($this->upload->do_upload($key))
{
$this->upload->data();
}
}
}
do_upload() method, its whole arrayThe HTML provided by ojjwood above will produce multiple input boxes. If you'd only like to have one input box but still upload multiple files, you need to include the attribute multiple="multiple" in your <input> element. The [] in name="userfile[]" allows the posted data to be an array and not just a single value.
On the Codeigniter/PHP side of things, you need to use $_POST['userfile] instead of $this->input->post('userfile') for working with arrays.
