File upload issue in codeigniter - php

Question

Actually while uploading a file I am creating folder with timestamp and also saving folder name along with filename to the database this is working fine. While editing I have input type hidden in this I am posting value if user do not change files and also if folder exits already it should not create folder and If user change files that time it should create a new folder.Only it is going to if condition. not else part.Please help me someone.
Below is PHP code,
if(isset($_FILES['event_image']['name'])&& $_FILES['event_image']['name']!="")
{
$folder_name =$_FILES['event_image']['name'];
echo $folder_name;
}
else
{
$folder_name =$_POST['image_exists'];
echo $folder_name;
}
//print_r($pathToUpload);die;
$old = umask(0);
if (!file_exists($folder_name))
{
//echo "djfgd";die;
$folderName = $_POST['event_name'].time();
$pathToUpload = 'images/events/' . $folderName;
$create = mkdir($pathToUpload, 0777,true);
//chmod($pathToUpload,0755,true);
if ( ! $create )
return;
}
else{
//echo "dqqqqqq";die;
//$folderName = $_POST['event_name'].time();
//$pathToUpload = 'images/events/' . $folderName;
//$create = mkdir($pathToUpload, 0777,true);
echo "already exits";die;
}
umask($old);
HTML code:
<div class="col-md-6">
<div class="form-group">
<label for="event_image">Event Banner</label>
<input type="file" value="<?php echo $event_image; ?>"
class="form-control" id="eventimage" name="event_image">
<input type="hidden" name="image_exists" value="<?php echo $event_image;?>"
class="form-control" id="eventimage" placeholder="Enter Image Text" aria-describedby="fileHelp">
<div><?php echo $event_image;?></div>
</div>
</div>

Alright I have simulated your case on my machine using Codeigniter and simple PHP is_dir function.
Here is my test view
Created with Following Markup
<div class="container" style="margin-top:100px; ">
<div class="col-md-6" style="border: 1px dotted red; ">
<?php if(isset($errors)){?>
<div class="alert alert-danger">
<?php print_r($errors);?>
</div>
<?php }?>
<?php if(isset($success)){?>
<div class="alert alert-success">
<?php print_r($success);?>
</div>
<?php }?>
<form action="" method="post" id="form1">
<div class="form-group">
<label > Directory Name</label>
<input type="text" name="name" class="form-control" >
</div>
<div class="form-group">
<button type="submit" class="btn btn-danger" >Create</button>
</div>
</form>
</div>
</div>
My Controller
public function index()
{
$data['title']='Multiple submit';
if($_POST)
{
$path='uploads/'.$_POST['name'];
if (!is_dir($path)) {
mkdir($path);
$data['success']='Directory Created Successfully';
$this->load->view('form',$data);
}
else
{
$data['errors']='Directory Already Exist';
$this->load->view('form',$data);
}
}
else
{
$this->load->view('form',$data);
}
}
I create a directory, which is success.
I try it again, get an error
The Directory created in my path is
I hope you can modify this code as per your requirements.
