Pembaruan: Sepertinya ini akan didukung di 5.0+. Lihat tiket # 43458
Default
Ini adalah bagaimana file favicon ( .ico) muncul di tampilan Media Grid :
Ini adalah bagian yang sesuai dari template mikro:
<# } else if ( 'image' === data.type && data.sizes ) { #>
<div class="centered">
<img src="{{ data.size.url }}" draggable="false" alt="" />
</div>
<# } else { #>
<div class="centered">
<# if ( data.image && data.image.src && data.image.src !== data.icon ) { #>
<img src="{{ data.image.src }}" class="thumbnail" draggable="false" />
<# } else { #>
<img src="{{ data.icon }}" class="icon" draggable="false" />
<# } #>
</div>
<div class="filename">
<div>{{ data.filename }}</div>
</div>
<# } #>
di mana data.sizeskosong untuk favicons .
Metode 1) Menggunakan wp_mime_type_iconfilter
Jenis pantomim untuk favicons adalah image/x-icon.
Saya berhasil menampilkan .icofile dalam tampilan Media Grid dengan:
add_filter( 'wp_mime_type_icon', function( $icon, $mime, $post_id )
{
if( $src = false || 'image/x-icon' === $mime && $post_id > 0 )
$src = wp_get_attachment_image_src( $post_id );
return is_array( $src ) ? array_shift( $src ) : $icon;
}, 10, 3 );
di mana penting di sini untuk menjaga parameter ketiga wp_get_attachment_image_srcas $icon = false(secara default) untuk menghindari infinite loop!
Favicon kemudian ditampilkan seperti ini:
Metode 2) Menggunakan wp_prepare_attachment_for_jsfilter
Saat kami memuat tampilan kisi media, kami melakukan panggilan ke wp_ajax_query_attachmentshandler. Ia melakukan permintaan lampiran berikut:
$query = new WP_Query( $query );
$posts = array_map( 'wp_prepare_attachment_for_js', $query->posts );
Dalam wp_prepare_attachment_for_jsfungsi ini , berbagai informasi ditambahkan ke WP_Postposting dan disaring dengan:
return apply_filters( 'wp_prepare_attachment_for_js', $response, $attachment, $meta );
di mana output adalah $responsearray.
Kita dapat menggunakan filter ini untuk menambahkan ukuran yang tidak ada untuk favicon:
add_filter( 'wp_prepare_attachment_for_js', function( $response, $attachment, $meta )
{
if( 'image/x-icon' === $response['mime']
&& isset( $response['url'] )
&& ! isset( $response['sizes']['full'] )
)
{
$response['sizes'] = array( 'full' => array( 'url' => $response['url'] ) );
}
return $response;
}, 10, 3 );
dan mereka akan muncul seperti ini:
Perhatikan bahwa kita hanya mengatur urlbagian dan bukan bagian width, heightdan orientation. Kami selanjutnya dapat memperluas solusi untuk menambahkan data ini, dengan bantuan wp_get_attachment_image_src()fungsi, misalnya. Tapi aku menyerahkannya padamu ;-)
Beberapa $responsecontoh:
