@Colin Williams: thanks for the code! I had some time and build on your code to make it give error messages, data array and FAIL or SUCCES for every file uploaded.
When uploading files with their names as array ‘fieldname[]’ the following return values change:
- do_upload() returns an array with TRUE or FALSE values telling you which file failed when uploading
- display_errors() returns an array of error messages returned per file upload.
- data() returns an array of data arrays as returned per file upload
Hope this helps.
Edit 26/02/2011:
- display_errors() now gives back an array of the error messages
- the original upload class generates an error message for file fields that were left blank. This class ignores those errors and sets the ‘success’ to ‘NULL’ so you can filter those out.
<?php
class MY_Upload extends CI_Upload {
var $my_config;
var $my_error_msg = array();
var $my_data = array();
var $error_count = 0;
function MY_Upload($props = array())
{
$this->my_config = $props;
parent::CI_Upload($props);
}
function do_upload($field = 'userfile')
{
$success = FALSE;
if (isset($_FILES[$field]) and is_array($_FILES[$field]['error']))
{
// Create a pseudo file field for each file in our array
for ($i = 0; $i < count($_FILES[$field]['error']); $i++)
{
// Give it a name not likely to already exist!
$pseudo_field_name = '_psuedo_'. $field .'_'. $i;
// Mimick the file
$_FILES[$pseudo_field_name] = array(
'name' => $_FILES[$field]['name'][$i],
'size' => $_FILES[$field]['size'][$i],
'type' => $_FILES[$field]['type'][$i],
'tmp_name' => $_FILES[$field]['tmp_name'][$i],
'error' => $_FILES[$field]['error'][$i]
);
if ($_FILES[$field]['error'][$i] != 4)
{
// Let do_upload work it's magic on our pseudo file field
$success[$i] = parent::do_upload($pseudo_field_name);
$this->my_data[] = parent::data();
$this->my_error_msg = array_merge($this->my_error_msg, $this->error_msg);
} else {
// Let do_upload work it's magic on our pseudo file field
parent::do_upload($pseudo_field_name);
// Since this is an empty field, set $succes to NULL
$success[$i] = 'NULL';
$this->my_data[] = parent::data();
$this->my_error_msg = array_merge($this->my_error_msg, $this->error_msg);
}
// Count the errors
if ($success[$i] === FALSE)
{
$this->error_count++;
}
// Re-initialize after every file
parent::initialize($this->my_config);
}
}
else if (isset($_FILES[$field]))
// Works just like do_upload since it's not an array of files
{
$success = parent::do_upload($field);
}
return $success;
}
