I need to check the resolution of an image I want to upload via media box, and then upload it into a custom directory.

As a starting point I used part of the code from How Can I Organize the Uploads Folder by Slug (or ID, or FileType, or Author)?

And a part of it looks like this:

function wpse_25894_custom_upload_dir($path)
{   

    $use_default_dir = ( isset($_REQUEST['post_id'] ) && $_REQUEST['post_id'] == 0 ) ? true : false; 
    if( !empty( $path['error'] ) || $use_default_dir )
        return $path; //error or uploading not from a post/page/cpt 

    //THIS LINE PRODUCE ERROR. HERE I NEED TO GET WIDTH AND HEIGHT OF IMAGE I WANT TO UPLOAD
    list($width, $height) = getimagesize($path.'/'.$_POST['name']); 
    $customdir = '/'.$width.'x'.$height; //uplaod folder will be for example '640x480'

    $path['path']    = str_replace($path['subdir'], '', $path['path']); //remove default subdir (year/month)
    $path['url']     = str_replace($path['subdir'], '', $path['url']);      
    $path['subdir']  = $customdir;
    $path['path']   .= $customdir; 
    $path['url']    .= $customdir;  

    return $path;
}

$_POST['name'] contains file name of image, like 'myimage.jpg'.

what is the status of this question, is it still unsolved? –  birgire May 22 '13 at 22:16

In this part:

getimagesize($path.'/'.$_POST['name']); 

the variable $path is an array. Try to use

getimagesize($path['path'].'/'.$_POST['name']); 

instead.
