[resolved] Abspath? (2 posts)

    Having successfully written my first plug-in (I like it and it works), I thought I would move on to something a little more ambitious, that will hopefully increase my knowledge of WP and how it works. I am writing a simple gallery plug-in. I know there are a lot about, but none seem to do what I really want and using someone else's (no matter how good) defeats the object of me learning how to write plug-ins.

    Anyway I have created 2 folders, one that contains medium images and the other contains the thumbnail images. Naturally I want to be able to display the thumbnail as a link to the medium image and am using the code
    define('TJIMAGE_PATH', ABSPATH . 'images/tj-gallery');
    to define the path to the gallery and

    $query = "SELECT photo_name FROM wp_tjgallery_photo WHERE cat_id = $c_id";
    $result = @mysql_query($query);
    while ($row = mysql_fetch_array($result, MYSQL_NUM)){
    echo'<tr><td><a href="' . TJIMAGE_PATH . '/medium/' . $row[0] . '">. TJIMAGE_PATH . '/thumb/thumb_' . $row[0] . '"</td></tr>';
    }

    to create the link. However this shows the full path to my gallery and clicking the link gives a 404 error.
    I think the problem lies in my use of ABSPATH, but I cannot seem to find any documentation for this and have just picked up what I can from deconstructing other plug-ins. Can anyone see where I'm going wrong? An example can be found here

  2. Definitely not correct.

    ABSPATH is the server's path to the wordpress main root directory. You use it in things like includes and requires and such. Anytime you need to reference a local file.

    If you're building an actual link, you want to use the bloginfo() or get_bloginfo() functions. bloginfo() will display a parameter, get_bloginfo() will return it to you as a string.

    So, try this:
    define('TJIMAGE_PATH', get_bloginfo('url'). 'images/tj-gallery');
