This error may cause due to missing attribute of form tag, add -> enctype="multipart/form-data" attribute in form tag and try like:

<form method="post" action="<?php echo base_url()?>men/image_upload" id="upload_form" enctype="multipart/form-data" /> <input type="file" name="image_file"> <input type="submit" id="upload" name="upload" value="Upload" /> </form>

First of all if you want to upload file you need to add enctype attribute to the form. Add enctype= multipart/form-data attribute to the form and try again.

<!DOCTYPE html>
<html>
<head>
<title>image</title>
<link rel="stylesheet" type="text/css" href="<?php echo base_url();? 
 >/public/css/bootstrap.css">
</head>
  <body>
  <form method="post" enctype="multipart/form-data" action="<?php echo base_url()?>men/image_upload"  
 id="upload_form" />
    <input type="file" name="image_file">
    <input type="submit" id="upload" name="upload" value="Upload" />
</form>

 </body>
  </html>
