I'm using this code in my plugin to add an extra field to the user profiles so that the user can upload an image. It uploads the file perfectly but the only problem is the part that has to delete the previous uploaded image doesn't work.

This is my code:

<?php 
add_action( 'show_user_profile', 'my_show_extra_profile_fields' );
add_action( 'edit_user_profile', 'my_show_extra_profile_fields' );

function my_show_extra_profile_fields( $user ) { 
?>
<script type="text/javascript">
    var form = document.getElementById('your-profile');
    form.encoding = "multipart/form-data";
    form.setAttribute('enctype', 'multipart/form-data');
</script>
<table class="form-table">
    <tr>
        <th><label for="profile_photo">Upload your profile photo</label></th>
        <td>
        <p>
            <input type="file" name="profile_photo" id="profile_photo" />
            <input type="hidden" name="action" value="save">
            <input type="submit" name="submitprofilephoto" id="submitprofilephoto" class="button" value="بارگذاری"> 
        </p>
            <span class="description">
            <?php
            $author_profile_photo = get_author_profile_photo($user->ID);
            if(is_array($author_profile_photo)):
            ?>
                <a href="<?php echo $author_profile_photo["url"];?>" target="_blank">
                    <img src="<?php echo $author_profile_photo["file"];?>" height="100" width="100" />
                </a>
            <?php
            endif;
            ?>
            </span>
        </td>
    </tr>
</table>

<?php 
}

            // handle the uploaded file
            $overrides = array('test_form' => false);
            $file=wp_handle_upload($upload, $overrides);
            $file["file"] = $uploads["subdir"]."/".basename($file["url"]);

1 Hi and welcome! Kudos for showing what you did try. Just a hint for your next Questions: try to isolate the problem before posting the code, see the guide SSCCE. If I were you, I'd follow @toscho's advice, and if you can't make it work, you can update the Question (edit) with the new code. – brasofilo Commented Oct 20, 2013 at 17:15

I don't think the code above does give the uploaded file an id?! does it? if it does, then how are we suppose to get the id of it?! – aminb5 Commented Oct 20, 2013 at 18:11

I figured it out! the problem is the path is not right! Thanks to this post : Alow users to delete uploaded images inside backend?

this function below helped :

 function url_to_path_test($url){
    $url=str_replace(rtrim(get_site_url(),'/').'/', ABSPATH, $url);
   return $url;
   }

So in my code if you change the remove previous image like this it will work :

  //remove previous uploaded file
  $author_profile_photo = get_author_profile_photo($user_id);
  $url=str_replace(rtrim(get_site_url(),'/').'/', ABSPATH, $author_profile_photo["file"]);
  @unlink($url);

I realized that the code below is a much better solution :

 //remove previous uploaded file
  $author_data = get_the_author_meta( 'profile_photo', $user_id );
  $author_data["file"] = $uploads["path"] . $author_data["file"];

  $imagepath = $author_data["file"];
  @unlink($imagepath);

Here give full url of your file where it is located.

      unlink(public_path('file/to/delete'))

as you are just providing file name in your code

    @unlink($author_profile_photo["file"]);

and with if you want to prevent generating an error if the file does not exist.

This is my code:

<?php 
add_action( 'show_user_profile', 'my_show_extra_profile_fields' );
add_action( 'edit_user_profile', 'my_show_extra_profile_fields' );

function my_show_extra_profile_fields( $user ) {
