I have problem in uploading multiple Image in codeigniter
myview
<tr>
<td> Picture</td>
<td>:</td>
<td><input type="file" name="userfile[]" multiple /></input></td>
</tr>
and my model
function multi_upload_files($imagepath=''){
$number_of_files_uploaded = count($_FILES['userfile']['name']);
for ($i = 0; $i < $number_of_files_uploaded; $i++) {
$_FILES['userfile']['name'] = $_FILES['userfile']['name'][$i];
$_FILES['userfile']['type'] = $_FILES['userfile']['type'][$i];
$_FILES['userfile']['tmp_name'] = $_FILES['userfile']['tmp_name'][$i];
$_FILES['userfile']['error'] = $_FILES['userfile']['error'][$i];
$_FILES['userfile']['size'] = $_FILES['userfile']['size'][$i];
$config['upload_path'] = $imagepath;
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['max_size'] = 900;
$config['max_width'] = 2024;
$config['max_height'] = 1068;
$this->upload->initialize($config);
$fileData = $this->upload->data();
$uploadData[$i]['file_name'] = $fileData['file_name'];
$images[]= $uploadData[$i]['file_name'];
return $images;
} }
I have testing it and the problem this code just read my upload Image just 1 image, not equal to number of my file that just upload (for ex: 2 image)

If you look at the following lines, you just overwrote everything with the first item in the array. Thus, only the first item is processed and the rest are overwritten. Plus, you have a return at the end of the loop. The function returns before the loop can finish.
$_FILES['userfile']['name'] = $_FILES['userfile']['name'][$i];
$_FILES['userfile']['type'] = $_FILES['userfile']['type'][$i];
$_FILES['userfile']['tmp_name'] = $_FILES['userfile']['tmp_name'][$i];
$_FILES['userfile']['error'] = $_FILES['userfile']['error'][$i];
$_FILES['userfile']['size'] = $_FILES['userfile']['size'][$i];
...
return $images;

You miss two things.
First,variable $imagepath is not defined.
Second, You miss to load upload libaray.
So,Solution is here try it.Hope it will works...
function multi_upload_files($imagepath=''){
$data = array();
$number_of_files_uploaded = count($_FILES['userfile']['name']);
for ($i = 0; $i < $number_of_files_uploaded; $i++) {
$_FILES['userfile']['name'] = $_FILES['userfile']['name'][$i];
$_FILES['userfile']['type'] = $_FILES['userfile']['type'][$i];
$_FILES['userfile']['tmp_name'] = $_FILES['userfile']['tmp_name'][$i];
$_FILES['userfile']['error'] = $_FILES['userfile']['error'][$i];
$_FILES['userfile']['size'] = $_FILES['userfile']['size'][$i];
$imagepath = 'Define upload path here';
$config['upload_path'] = $imagepath;
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['max_size'] = 900;
$config['max_width'] = 2024;
$config['max_height'] = 1068;
//Load library first then use
$this->load->library('upload');
$this->upload->initialize($config);
if($this->upload->do_upload('userfile'))
{
$fileData = $this->upload->data();
$uploadData[$i]['file_name'] = $fileData['file_name'];
$images[]= $uploadData[$i]['file_name'];
}
return $images;
}
