I have the following html code
<form action="form-handler.php" method="post" enctype="multipart/form-data">
<div>
<input id="myfile" name="myfile" type="file">
<input value="Upload ►" type="submit">
</div>
</form>
I want to upload multiple files at once. What should I do in controller to upload the selected files in codeigniter ? I tried using the Codeigniter file upload library, but it is not loading multiple files. Though, for 1 file it is working fine.
You can just call Codigniter's do_upload() function within a foreach loop that iterates through your array of posted files, $_FILE;
here's the code for this that goes in the controller function which receives the upload form POST:
$this->load->library('upload');
$this->upload->initialize($config); //$config is array like as [in CI's documentation][1]
$path='uploads/some_folder'; // refers to the root's uploads/some_folder folder
$upload_data = $this->upload->multiFileUpload($path, TRUE);
The magic is in the multiFileUpload() function which I got from someone else. This function is extended on CI's Upload library by putting it in a file called MY_Upload.php in my /application/libraries folder.
Here's the entire contents of MY_Upload.php which is really just the multiFileUpload() function so don't be intimidated you don't need to know anything other than the $path of where you want the files to go.
<?
class MY_Upload extends CI_Upload {
public function multiFileUpload($path, $protect = FALSE){
/*
* Declare uploaded_info and uploaded_files
* when i'm sure $_FILES has some data
*/
/* if($this->upload_path[strlen($this->upload_path)-1] != '/')
$this->upload_path .= '/';*/
//$this->upload_path=$path;
if(isset($_FILES)){
#Here we check if the path exists if not then create
/*if(!file_exists($this->upload_path)){
@mkdir($this->upload_path,0700,TRUE);
}*/
if(!file_exists($path)){
@mkdir($path,0700,TRUE);
}
$uploaded_info = FALSE;
/*
* The structure of $_FILES changes a lot with the array name on the input file,
* then i'm gonna modify $_FILES to make it think the data comes from several
* input file instead of one "arrayfied" input.
*
* The several ways to upload files are controled with this if...else structure
*/
if(count($_FILES) == 1)
{
$main_key = key($_FILES);
if(is_array($_FILES[$main_key]['name']))
{
foreach($_FILES[$main_key] as $key => $value)
{
for($y = 0; $y < count($value); $y++)
{
$_FILES[$main_key .'-'. $y][$key] = $value[$y];
}
}
unset($_FILES[$main_key]);
$uploaded_files = $_FILES;
}
else
{
$uploaded_files = $_FILES;
}
}
else
{
$uploaded_files = $_FILES;
}
#Here we create the index file in each path's directory
/*if($protect){
$folder = '';
foreach(explode('/',$this->upload_path) as $f){
$folder .= $f.'/';
$text = "<?php echo 'Directory access is forbidden.'; ?>";
if(!file_exists($folder.'index.php')){
$index = $folder.'index.php';
$Handle = fopen($index, 'w');
fwrite($Handle, trim($text));
fclose($Handle);
}
}
}*/
#Here we do the upload process
foreach($uploaded_files as $file => $value){
if (!$this->do_upload($file))
{
$uploaded_info['error'][] = array_merge($this->data(),
array('error_msg' => $this->display_errors()));
}
else
{
$uploaded_info['upload_data'][] = array_merge($this->data(),
array('error_msg' => $this->display_errors()));
}
}
}
#Then return what happened with the files
return $uploaded_info;
