Hi,
I would like to rename the attached files of a comment (using the media uploader plugin) and use the title of the current post. So I created a snippet to add this code when the sanitize_file_name function is call.
But this doesn't work, it seems that I can't acces to the post, even if I use a global $post.
Do you have an idea ?
Thanks
Â
function my_custom_file_name( $filename ) {
$info = pathinfo( $filename );
$ext = empty( $info['extension'] ) ? '' : '.' . $info['extension'];
$name = basename( $filename, $ext );
if ( isset( $_REQUEST['post_id'] ) && is_numeric( $_REQUEST['post_id'] ) ) {
$postObj = get_post( $_REQUEST['post_id'] );
$postSlug = sanitize_title( $postObj->post_title );
}
if ( isset( $postSlug ) && ! empty( $postSlug ) ) {
$finalFileName = $postSlug;
} // File name will be the same as the post slug.
else {
$finalFileName = sanitize_title( $name );
} // File name will be the same as the image file name, but sanitized.
return $finalFileName . $ext;
}
add_filter( 'sanitize_file_name', 'my_custom_file_name', 100 );
New test : when I try to get the url of my page, I only get the base url of my domain, not the full url of my post...
Is it because the upload is done in js ?
global $wp; $current_url = home_url( add_query_arg( array(), $wp->request ) );
The wp_insert_attachment function is used for inserting the attachments. The wp_insert_attachment calls the wp_insert_post function as well. So you should use those functions.Â
As far as the file uploading use the AJAX method you can't change the filename using the sanitize_file_name. The global post isn't accessible when the AJAX method is used for file uploading.Â
@asti Thank you for your answer and your explanation !
I finally use the add_attachment function and it works well !
Here is my code, if it could helps somebody.
add_action('add_attachment', 'rename_attachment');
function rename_attachment($post_ID){
  $file = get_attached_file($post_ID);
  $path = pathinfo($file);
    //dirname  = File Path
    //basename = Filename.Extension
    //extension = Extension
    //filename = Filename
$post_title = get_the_title(get_post_parent($post_ID));
$user = wp_get_current_user()->display_name;
$newfilename = $user.'-'.$post_title;
$newfile = $path['dirname'].'/myFolder/'.$newfilename.'.'.$path['extension'];
  // Update WordpressÂ
  rename($file, $newfile);  Â
  update_attached_file( $post_ID, $newfile );
// Update metadata
$pathNewFile = pathinfo($newfile);
$meta = wp_get_attachment_metadata($post_ID);
$meta['file'] = str_replace( $path['basename'], $pathNewFile['basename'], $meta['file'] );
wp_update_attachment_metadata( $post_ID, $meta );
// Update media library post title
  $post = get_post($post_ID);Â
  $post->post_title = $newfilename;
  wp_update_post( $post );
}
