アップグレード中に生成されたメディアファイルの名前を変更する

WordPressのデフォルトのメディア名を変更してファイルから寸法を削除し、それらを単純な接尾辞に置き換えようとしています。

例えば：

  • imageA-300x300.jpg
  • imageA-480x480.jpg
  • imageA-1024x1024.jpg

なるだろう

  • imageA-thumb.jpg
  • imageA-medium.jpg
  • imageA-large.jpg

これどうやってするの？これまでは、wp_handle_upload_prefilterにフィルタを追加してみましたが、元の名前を変更するだけのようです...

からの私自身のコードを使って 、接尾辞の代わりに画像サイズの名前を追加するようにロジックを更新しました。これをfunctions.phpファイルに追加してみてください。

add_filter("wp_image_editors", "my_wp_image_editors");

function my_wp_image_editors($editors) {
    array_unshift($editors, "WP_Image_Editor_Custom");
    return $editors;
}

// Include the existing classes first in order to extend them.
require_once ABSPATH . WPINC . "/class-wp-image-editor.php";
require_once ABSPATH . WPINC . "/class-wp-image-editor-Gd.php";

class WP_Image_Editor_Custom extends WP_Image_Editor_Gd {

    public function generate_filename($suffix = null, $dest_path = null, $extension = null) {
        // $suffix will be appended to the destination filename, just before the extension
        if (!$suffix) {
            $suffix = $this->get_suffix();
        }

        $dir = pathinfo($this->file, PATHINFO_DIRNAME);
        $ext = pathinfo($this->file, PATHINFO_EXTENSION);

        $name = wp_basename($this->file, ".$ext");
        $new_ext = strtolower($extension ? $extension : $ext );

        if (!is_null($dest_path) && $_dest_path = realpath($dest_path)) {
            $dir = $_dest_path;
        }
        //we get the dimensions using explode, we could have used the properties of $this->file[height] but the suffix could have been provided
        $size_from_suffix = explode("x", $suffix);
        //we get the slug_name for this dimension
        $slug_name = $this->get_slug_by_size($size_from_suffix[0], $size_from_suffix[1]);

        return trailingslashit($dir) . "{$name}-{$slug_name}.{$new_ext}";
    }

    function get_slug_by_size($width, $height) {

        // Make thumbnails and other intermediate sizes.
        $_wp_additional_image_sizes = wp_get_additional_image_sizes();

        $image_sizes = array(); //all sizes the default ones and the custom ones in one array
        foreach (get_intermediate_image_sizes() as $s) {
            $image_sizes[$s] = array('width' => '', 'height' => '', 'crop' => false);
            if (isset($_wp_additional_image_sizes[$s]['width'])) {
                // For theme-added sizes
                $image_sizes[$s]['width'] = intval($_wp_additional_image_sizes[$s]['width']);
            } else {
                // For default sizes set in options
                $image_sizes[$s]['width'] = get_option("{$s}_size_w");
            }

            if (isset($_wp_additional_image_sizes[$s]['height'])) {
                // For theme-added sizes
                $image_sizes[$s]['height'] = intval($_wp_additional_image_sizes[$s]['height']);
            } else {
                // For default sizes set in options
                $image_sizes[$s]['height'] = get_option("{$s}_size_h");
            }

            if (isset($_wp_additional_image_sizes[$s]['crop'])) {
                // For theme-added sizes
                $image_sizes[$s]['crop'] = $_wp_additional_image_sizes[$s]['crop'];
            } else {
                // For default sizes set in options
                $image_sizes[$s]['crop'] = get_option("{$s}_crop");
            }
        }
        $slug_name = ""; //the slug name

        if($width >= $height){
          foreach ($image_sizes as $slug => $data) { //we start checking
            if ($data['width'] == $width) {//we use only width because regardless of the height, the width is the one used for resizing in all cases with crop 1 or 0
                $slug_name = $slug;
            }
            /*
             * There could be custom added image sizes that have the same width as one of the defaults so we also use height here
             * if there are several image sizes with the same width all of them will override the previous one leaving the last one, here we get also the last one
             * since is looping the entire list, the height is used as a max value for non-hard cropped sizes
             *  */
              if ($data['width'] == $width && $data['height'] == $height) {
                  $slug_name = $slug;
              }
          }
         }else{
           foreach ($image_sizes as $slug => $data) {
              if ($data['height'] == $height) {
                  $slug_name = $slug;
              }
              if ($data['height'] == $height && $data['width'] == $width ) {
                  $slug_name = $slug;
              }
            }
         }
        return $slug_name;
    }
}

不要なコードも削除しました。これはカスタムの画像サイズでも動作します。

home-bottomは私が持っているカスタム画像サイズです。
