WordPress: Remove attachment fields

2 Views

How do I remove attachment fields, like description and alt in media library of WordPress attachments?

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 );

But since then, I have not found a working solution.

Do anyone know a solution?

  1. 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.

    Overriding the Backbone micro templates – short version:

    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' );

    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' );

    Overriding the Backbone micro templates – long version:

    Here you can get the media templates used by the WordPress core.

    1) The following code example should remove the Caption, Alt Text and Description fields from the Attachments Details template:

    You can hopefully modify this to your needs.

  2. The styles can be printed on /wp-admin/post.php using admin_print_styles-$page, and selecting the elements using the data attribute.

    It’s possible to detect the current post type and only apply the rules on a given type:

    foreach( array( 'post.php', 'post-new.php' ) as $hook )
    add_action( "admin_print_styles-$hook", 'admin_styles_so_25894288');

function admin_styles_so_25894288() {
    global $typenow;
    if( 'post' !== $typenow )
        return;
    ?>
    <style>
        .media-sidebar .setting[data-setting="caption"],
        .media-sidebar .setting[data-setting="description"],
        .media-sidebar .setting[data-setting="alt"] { 
            display: none; 
        }
    </style>
    <?php
}

  3. Try this:

    add_action('admin_head', 'remove_attachment_field');
function remove_attachment_field() {
  echo "<style>div.attachment-info label.setting[data-setting=alt], div.attachment-info label.setting[data-setting=caption], div.attachment-info label.setting[data-setting=description] { display: none; }</style>";
}
