如何删除附件字段,如wordpress附件的媒体库中的描述和alt？
function remove_attachment_field ( $fields ) {
unset( $fields['image_alt'] ); // Removes ALT field
return $fields;
}
add_filter( 'attachment_fields_to_edit','remove_attachment_field',15,1 );
但从那以后,我还没有找到一个有效的解决方案.
有人知道解决方案吗？
澄清我想删除的字段：
@brasofilo的
above solution应该能够正常工作,但是我们也可以使用@EricAndrewLewis的
this great answer作为如何覆盖Backbone微模板的指导.
原文链接：https://www.f2er.com/php/131436.html覆盖骨干微模板 – 简短版本：
您可以使用以下命令覆盖您的自定义#tmpl-attachment-details-custom自定义的micro Backbone模板#tmpl-attachment-details：
wp.media.view.Attachment.Details.prototype.template = wp.media.template( 'attachment-details-custom' );
同样,您可以使用#tmpl-attachment-details-two-column-custom来覆盖微模板#tmpl-attachment-details-two-column：
wp.media.view.Attachment.Details.TwoColumn.prototype.template = wp.media.template( 'attachment-details-two-column-custom' );
