本文介绍了WordPress:删除附件字段的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
如何删除Wordpress附件媒体库中的附件字段，例如description和alt?
How do I remove attachment fields, like description and alt in media library of Wordpress attachments?
以下代码可用于旧版本的Wordpress(低于3.5版):
The following code use to work on old Wordpress versions (pre 3.5):
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 );
但是从那以后，我一直没有找到可行的解决方案.
But since then, I have not found a working solution.
有人知道解决方案吗?

推荐答案
@brasofilo的上述解决方案应该可以正常工作，但我们也可以使用@EricAndrewLewis的这个好答案作为如何覆盖骨干网的指南微型模板.
The above solution by @brasofilo should work well, but we can also use this great answer by @EricAndrewLewis as a guideline on how to override the Backbone micro templates.
您可以使用以下自定义#tmpl-attachment-details-custom覆盖微型骨干模板#tmpl-attachment-details:
You can override the micro Backbone template #tmpl-attachment-details with your custom #tmpl-attachment-details-custom using:
wp.media.view.Attachment.Details.prototype.template = wp.media.template( 'attachment-details-custom' );
类似地，您可以使用#tmpl-attachment-details-two-column-custom使用#tmpl-attachment-details-two-column-custom覆盖微型模板#tmpl-attachment-details-two-column:
Similarly you can override the micro template #tmpl-attachment-details-two-column with #tmpl-attachment-details-two-column-custom using:
wp.media.view.Attachment.Details.TwoColumn.prototype.template = wp.media.template( 'attachment-details-two-column-custom' );

在这里，您可以获取WordPress核心使用的媒体模板.
