Support » Networking WordPress » How to find the upload path for a blog? MU 2.9.2

  • Resolved sofaking21


    I would love to just change themes to one that works, but unfortunately I’m stuck with trying to figure out how to change a theme just enough to make it work in an MU environment.

    On the backend, users are allowed to upload a logo. Unfortunately, all these logo files go into a shared folder so if by some weird chance blog 5 decides to upload “header_image.png” but blog 1 is using that same filename, BOOM! Both blogs now have the same header. Blog 5 is happy, but blog 1 is cranky.

    Here’s the troublesome code:

    $directory = dirname(__FILE__)."/uploads/";
    move_uploaded_file($_FILES[$file]["tmp_name"], $directory.$_FILES[$file]["name"]);

    I’m going insane on trying to figure out how to get $directory to point to the proper blogs.dir/blog_id/files/ directory. I have used the get_option(‘upload_path’) which gets me almost everything I need. I just can’t figure out how to find the absolute path of the installation directory of WordPress. I’m going nuts trying to figure this out, any help would be greatly appreciated.

  • What file is the “troublesome code” in? If it really is WPMu 2.9.2, /uploads/ shouldn’t be in there. Just searched an archived WPMu 2.9.2 tree and nada.

    That code is the functions.php of the theme. Easiest solution: change themes, but the powers that be say that’s not an option.

    I’m wondering why the theme isn’t using the built-in header upload, which does toss it in the right spot.

    You’d be amazed how few themes use the built-in functions. This theme (Intrepidity) allows users to upload a custom header, footer and logo image. Another theme (Arras) does something similar (only allows for a custom logo), but uses the wp_handle_upload hook to upload to the proper blogs.dir/blog_id/files/ folder. I’ve tried recoding this section of code using that hook and I must’ve screwed something up pretty good.

    Is there any way to pull the value of WP_CONTENT_DIR that is defined in wp-settings.php?

    I officially feel dumb. Just in case anyone else ever runs into this type of issue, here’s how I solved it:

    $directory = ABSPATH.get_option('uplload_path').'/';

    I don’t know why it didn’t click to me that since some of these directories are defined as constants, I could just reference them directly.
