    Failed to Open Stream: Permission Denied

    Hi All,

    I can't seem to get the following code to work with a WordPress template. When I try to upload an avatar, I receive the following error:

    Code:
    Warning: copy(/admin.png) [function.copy]: failed to open stream: Permission denied in /home/user-name/domains/my-domain.com/public_html/wp-content/themes/adWhiteBullet/template-authoradmin.php on line 299
    I will add the number 299 in front of the appropriate line below. By any chance, does anyone see my goofheaded problem?

    Thank you in advance!

    Code:
    <?php
    ############### text above says jpg only but png will work if the echos are corrected in other places ####
    //define a maxim size for the uploaded images 10000 will turn into 1MB
    define ("MAX_SIZE","10240");
    // define the width and height for the thumbnail
    // note that theese dimmensions are considered the maximum dimmension and are not fixed,
    // because we have to keep the image ratio intact or it will be deformed
    define ("WIDTH","80");
    define ("HEIGHT","100");
     
    // this is the function that will create the thumbnail image from the uploaded image
    // the resize will be done considering the width and height defined, but without deforming the image
    function make_thumb($img_name,$filename,$new_w,$new_h)

    Is the upload folder writable?

    If I'm reading the code correctly, is /images/thumbs off the root directory? Or is it the root directory?

    For both of those folders, I chmod-ed them to 777. Unfortunately, the error persisted.

    Perhaps it's writing to a different folder (and I'm not reading the code right)?

    A friend said it might be a javascript error? Personally, I didn't see where that would come into play..

    Thanks again,

    Ansel

    The script gets the path through: get_option('upload_path')
    To know the value, just echo it.
    If it starts with '/', it means it starts from the root folder.

    Oop! It turned out to be a WordPress configuration error. I needed to add the upload directory to the Miscellaneous section of the Settings. I am sorry for wasting anyone's time!

    Thank you for the post, Guido.
