It is very simple to use pure PHP multi file Upload. Look into this script
View
<form method="post" action="<?php echo base_url('users/upload/'); ?>" enctype="multipart/form-data">
<label for="upload">Select : </label>
<input type="file" name="userfile[]" id="userfile" multiple="multiple" />
<input type="submit" name="fsubmit" id="fsubmit" value="Upload" />
</form>
Controller
public function album($id)
{
if (isset($_FILES['userfile']['name'])) {
// total files //
$count = count($_FILES['userfile']['name']);
// all uploads //
$uploads = $_FILES['userfile'];
for ($i = 0; $i < $count; $i++) {
if ($uploads['error'][$i] == 0) {
// FCPATH = root directory project
move_uploaded_file($uploads['tmp_name'][$i], FCPATH . 'assets/gallery/' . $uploads['name'][$i]);
echo $uploads['name'][$i] . "\n";
}
}
}
}
Hope this helps. Thanks!!
