Wordpress: uploading images using php - can't create different image sizes -


i trying simulate wordpress default upload process. here go images:

  <input type="file" name="imgsupload1[]" id="imgsupload1[]" multiple="">

the code should upload: 

$post_imgs = $_files['imgsupload1'];     foreach ($post_imgs['name'] $key => $value) {       if ($post_imgs['name'][$key]) {         $file = array(           'name'     => $post_imgs['name'][$key],           'type'     => $post_imgs['type'][$key],           'tmp_name' => $post_imgs['tmp_name'][$key],           'error'    => $post_imgs['error'][$key],           'size'     => $post_imgs['size'][$key]         );         $img_caption = $img_captions[urlencode(basename($file['name']))];         $new_file = wp_handle_upload($file, array( 'test_form' => false ));      $filename = $new_file['url'];     $filetype = wp_check_filetype( basename( $filename ), null );     $wp_upload_dir = wp_upload_dir();      // prepare array of post data attachment.     $attachment = array(         'guid'           => $wp_upload_dir['url'].'/'.basename( $filename ),          'post_mime_type' => $filetype['type'],         'post_title'     => preg_replace( '/\.[^.]+$/', '', basename( $filename ) ),         'post_content'   => '',         'post_status'    => 'inherit',         'post_excerpt' => $img_caption     );      require_once( abspath.'wp-admin/includes/image.php' );     $img_id = wp_insert_attachment( $attachment, $filename, $post_id );     $img_data = wp_generate_attachment_metadata( $img_id, $wp_upload_dir['basedir'].'/'.basename( $filename ) );     wp_update_attachment_metadata( $img_id, $img_data );        }   // if image[key] exists     }   // foreach uploaded image

the image size defined default not created. seems problem in wp_generate_attachment_metadata

the problem in wp_generate_attachment_metadata, passing proper absolute path, need use 'path' element in wp_upload_dir array:

$img_data = wp_generate_attachment_metadata( $img_id, $wp_upload_dir['path'].'/'.basename( $filename ) );

which different written in codex. hope someone.
