try to use this function .Define this in your function.php

<?php
function upload_user_file( $file = array() ) {

    require_once( ABSPATH . 'wp-admin/includes/admin.php' );

      $file_return = wp_handle_upload( $file, array('test_form' => false ) );

      if( isset( $file_return['error'] ) || isset( $file_return['upload_error_handler'] ) ) {
          return false;
      } else {

          $filename = $file_return['file'];

          $attachment = array(
              'post_mime_type' => $file_return['type'],
              'post_title' => preg_replace( '/\.[^.]+$/', '', basename( $filename ) ),
              'post_content' => '',
              'post_status' => 'inherit',
              'guid' => $file_return['url']
          );

          $attachment_id = wp_insert_attachment( $attachment, $file_return['url'] );

          require_once(ABSPATH . 'wp-admin/includes/image.php');
          $attachment_data = wp_generate_attachment_metadata( $attachment_id, $filename );
          wp_update_attachment_metadata( $attachment_id, $attachment_data );

          if( 0 < intval( $attachment_id ) ) {
            return $attachment_id;
          }
      }

      return false;
}
?>

and use like this

    <?php
    if(isset($_POST['upload']))
    {
       if( ! empty( $_FILES ) ) 
       {
          $file=$_FILES['file'];
          $attachment_id = upload_user_file( $file );

       }
    }
    ?>

<form action="" method="post" enctype="multipart/form-data">
    <input type="file" name="file">
    <input type="submit" name="upload">
</form>

thanks but how will this function run in functions.php file ... we have not used any function call or can I use a shortcode please guide and also kindly note that there is a custom folder not the wordpress folder where I want to upload file ... thanks

why you want to use shortcode ?? and you will get attachment id you can get image through attachment id of any size you want . and we call this function on the page where the form exists.

Infact I am creating an image upload competition functionality where users can upload images and others can rate and their will be a winner who has the most votes. So how can I upload to a custom folder other then the default upload folder

There is a tiny error in the script: $attachment_id = wp_insert_attachment( $attachment, $file_return['url'] ); should be: $attachment_id = wp_insert_attachment( $attachment, $file_return['file'] );

if you want to upload in a custom folder you can use this function

add the function in functions.php

function upload_user_file( $file = array(),$path ) {
    if(!empty($file)) 
    {


        $upload_dir=$path;
        $uploaded=move_uploaded_file($file['tmp_name'], $upload_dir.$file['name']);
        if($uploaded) 
        {
            echo "uploaded successfully ";

        }else
        {
            echo "some error in upload " ;print_r($file['error']);  
        }
    }

}

make a form in your template file like this

<form action="" method="post" enctype="multipart/form-data">
    <input type="file" name="file">
    <input type="submit" name="upload">
</form>

call the upload function in template file like before get_header(); function

if(isset($_POST['upload']))
    {

       if( ! empty( $_FILES ) ) 
       {
          $file=$_FILES['file'];   // file array
          $upload_dir=wp_upload_dir();
          $path=$upload_dir['basedir'].'/myuploads/';  //upload dir.
          if(!is_dir($path)) { mkdir($path); }
          $attachment_id = upload_user_file( $file ,$path);

       }
    }

i know this old, but how would you echo the image path after uploading?
