Wordpress:覆盖媒体网格中附件"thumbnails"的模板



当您单击"编辑帖子"页面中的"添加媒体"按钮时,我正在尝试自定义媒体浏览器的模板,但它不起作用。我的目的是在缩略图上添加文件名作为标题,因此我无需选择图像即可在"附件详细信息"面板上检查其文件名。

我发现了这个非常好的答案,关于如何通过在媒体模板中覆盖附件详细信息模板来自定义它.php:

https://stackoverflow.com/a/25948448/8717608

它完美无瑕。

因此,从理论上讲,我应该能够调整该答案以覆盖附件模板,该模板位于此处的第 506 行中:

这是我的版本:

add_action( 'wp_enqueue_media', 'add_media_overrides' );
function add_media_overrides() {
    add_action( 'admin_footer-post.php', 'override_media_templates' );
}
function override_media_templates(){
    ?> 
    <script type="text/html" id="tmpl-attachment_custom">
        <div class="attachment-preview js--select-attachment type-{{ data.type }} subtype-{{ data.subtype }} {{ data.orientation }}">
            <div class="thumbnail">

                    <div class="media-progress-bar"><div style="width: {{ data.percent }}%"></div></div>

                <input type="text" value="{{ data.title }}" class="describe" data-setting="title"
                    <# if ( 'video' === data.type ) { #>
                        placeholder="<?php esc_attr_e( 'Describe this video&hellip;' ); ?>"
                    <# } else if ( 'audio' === data.type ) { #>
                        placeholder="<?php esc_attr_e( 'Describe this audio file&hellip;' ); ?>"
                    <# } else { #>
                        placeholder="<?php esc_attr_e( 'Describe this media file&hellip;' ); ?>"
                    <# } #> {{ maybeReadOnly }} />
            <# }
        } #>
    </script>
    <script>
        jQuery(document).ready( function($) {
            if( typeof wp.media.view.Attachment != 'undefined' ){
                wp.media.view.Attachment.prototype.template = wp.media.template( 'attachment-custom' );
            }
        });
    </script>
    <?php
}

通过单击"添加媒体"按钮,我希望在黑色背景中看到所有带有文件名的拇指,但没有任何反应。看起来我错过了一些东西...

有一个错别字,而不是:

wp.media.view.Attachment.prototype.template = wp.media.template( 'attachment-custom' );

应该是:

wp.media.view.Attachment.prototype.template = wp.media.template( 'attachment_custom' );
