不为CPT生成拇指

Question

我正在寻找一种方法，以避免在CPT上传新图像时创建图像拇指。

因此，在我的functions.php中，我有：

if ( function_exists( 'add_theme_support' ) ) {
add_theme_support( 'post-thumbnails' );
set_post_thumbnail_size( 56, 56, true ); // Normal post thumbnails
add_image_size( 'tinyfeatured', 50, 50, true ); // Tiny Featured thumbnail
add_image_size( 'blogonecol', 530, '', true ); // Blog One Column thumbnail
add_image_size( 'post', 530, '', true ); // Portfolio Large thumbnail
add_image_size( 'postnc', 700, '', false ); // Portfolio Large thumbnail
add_image_size( 'carousel', 560, 341, true ); // Portfolio Large thumbnail
add_image_size( 'magazine-full', '', 1131, true); // Portfolio Large thumbnail
}

为了避免为我正在使用的CPT创建所有这些图像大小，我这样做了：

if ( function_exists( 'add_theme_support' ) ) {
add_theme_support( 'post-thumbnails' );
if( !is_singular('issues') ) {
set_post_thumbnail_size( 56, 56, true ); // Normal post thumbnails
add_image_size( 'tinyfeatured', 50, 50, true ); // Tiny Featured thumbnail
add_image_size( 'blogonecol', 530, '', true ); // Blog One Column thumbnail
add_image_size( 'post', 530, '', true ); // Portfolio Large thumbnail
add_image_size( 'postnc', 700, '', false ); // Portfolio Large thumbnail
add_image_size( 'carousel', 560, 341, true ); // Portfolio Large thumbnail
}
add_image_size( 'magazine-full', '', 1131, true); // Portfolio Large thumbnail
}

但是，当我在CPT“问题”中上传新的图像时，上面的所有图像大小都被创建了。

有没有其他方法可以避免这种情况？

Answer 1

尝试在条件中使用unset( $sizes['tinyfeatured']);，这样当它是CPT“问题”时，您可以取消设置大小，而当它相反时，则设置大小。如下所示：

if( is_singular('issues') ) {
  function sgr_filter_image_sizes( $sizes) {
    
    unset( $sizes['tinyfeatured']);
    unset( $sizes['blogonecol']);
    unset( $sizes['post']);
    unset( $sizes['postnc']);
    unset( $sizes['carousel']);

    return $sizes;
  }
    add_filter('intermediate_image_sizes_advanced', 'sgr_filter_image_sizes');
}

编辑过的试试这个大小

function add_new_thumbnails() {
  if ( function_exists( 'add_theme_support' ) ) {
  add_theme_support( 'post-thumbnails' );

  set_post_thumbnail_size( 56, 56, true ); // Normal post thumbnails
  add_image_size( 'tinyfeatured', 50, 50, true ); // Tiny Featured thumbnail
  add_image_size( 'blogonecol', 530, '', true ); // Blog One Column thumbnail
  add_image_size( 'post', 530, '', true ); // Portfolio Large thumbnail
  add_image_size( 'postnc', 700, '', false ); // Portfolio Large thumbnail
  add_image_size( 'carousel', 560, 341, true ); // Portfolio Large thumbnail
  add_image_size( 'magazine-full', '', 1131, true); // Portfolio Large thumbnail
  }
 }
 add_action('after_setup_theme', 'add_new_thumbnails',10); //10 is default

将此代码与顶级代码一起使用，但添加12的筛选器优先级

add_filter('intermediate_image_sizes_advanced', 'sgr_filter_image_sizes',12);

将其放入您的functions.php中，而不是您添加的代码

新方法

因此，可以尝试的新方法是：

function add_new_thumbnails() {
 add_theme_support( 'post-thumbnails' );

 set_post_thumbnail_size( 56, 56, true ); // Normal post thumbnails
 add_image_size( 'tinyfeatured', 50, 50, true ); // Tiny Featured thumbnail
 add_image_size( 'blogonecol', 530, '', true ); // Blog One Column thumbnail
 add_image_size( 'post', 530, '', true ); // Portfolio Large thumbnail
 add_image_size( 'postnc', 700, '', false ); // Portfolio Large thumbnail
 add_image_size( 'carousel', 560, 341, true ); // Portfolio Large thumbnail
 add_image_size( 'magazine-full', '', 1131, true); // Portfolio Large thumbnail
}

add_action('init', 'add_new_thumbnails',10); //10 is default

if ( is_singular('issues') ) {
function remove_thumbnails() {
    add_image_size( 'tinyfeatured', 0, 0 ); // Tiny Featured thumbnail
    add_image_size( 'blogonecol', 0, 0); // Blog One Column thumbnail
    add_image_size( 'post', 0,0 ); // Portfolio Large thumbnail
    add_image_size( 'postnc',0,0 ); // Portfolio Large thumbnail
    add_image_size( 'carousel',0,0 ); // Portfolio Large thumbnail
    add_image_size( 'magazine-full',0,0); // Portfolio Large thumbnail
 }
add_action('init', 'remove_thumbnails',12); // 12 executes after 10

}
