Removing fields from the Media Uploader/Gallery

I’ve been searching high and low for an answer.

I simply want to remove the Alternate Text, Caption, Description and Link URL-fields from the uploader and gallery view.

I seem that every thing else than this Media-thingy can be removed.

Thanx for helping out:)

Method 1

You can do this via a filter. Add the following to functions.php. You can also add your own fields this way…

// edit fields in media upload area
add_filter('attachment_fields_to_edit', 'remove_media_upload_fields', 10000, 2);
function remove_media_upload_fields( $form_fields, $post ) {

    // remove unnecessary fields
    unset( $form_fields['image-size'] );
    unset( $form_fields['post_excerpt'] );
    unset( $form_fields['post_content'] );
    unset( $form_fields['url'] );
    unset( $form_fields['image_url'] );
    unset( $form_fields['align'] );

    return $form_fields;
}

The example above strips out more than you need to but if you do a print_r() on the $form_fields variable you’ll see what’s available to add/remove.

Method 2

Unfortunately it looks like this changed quite a bit in WP3.5 when they upgraded the media library. That filter’s $form_fields parameter doesn’t contain the defaults any more. The only solution I’ve found so far is to forcibly remove the markup from the view using buffering:

This is extremely fragile – any change to the WordPress core might break this

function wpse45562_remove_media_fields( $buffer ) {
    // remove the 'caption' block
    $buffer = preg_replace( '~<p>s*<labels*for="attachment_caption">.*?</p>~ims', '', $buffer );
    // remove the 'alt text' block
    $buffer = preg_replace( '~<p>s*<labels*for="attachment_alt">.*?</p>~ims', '', $buffer );

    // remove the 'description' box (and label separately)
    $buffer = preg_replace( '~<divs*id="wp-attachment_content-editor.*?</div>~ims', '',   $buffer );
    $buffer = preg_replace( '~<labels*for="content">.*?</label>~ims', '', $buffer );

    return $buffer;
}

function wpse45562_media_strip_buffer_start() { ob_start("wpse45562_remove_media_fields");  }
function wpse45562_media_strip_buffer_end() { ob_end_flush(); }

add_action('admin_head', 'wpse45562_media_strip_buffer_start', 10, 1);
add_action('admin_footer', 'wpse45562_media_strip_buffer_end', 10, 1);

Method 3

Since WP 3.5, the simplest way is to just remove fields with CSS:

add_action('admin_head', 'custom_remove_attachment_fields');
function custom_remove_attachment_fields() {
    ?><style type='text/css'>
        .attachment-info .setting.has-description,/* Alternative Text */
        .attachment-info #alt-text-description,/* Alternative Text description */
        .attachment-info .setting[data-setting="title"],
        .attachment-info .setting[data-setting="caption"],
        .attachment-info .setting[data-setting="description"],
        .attachment-info .setting[data-setting="url"],
        .attachment-info .media-types.media-types-required-info /* Required info */ {
            display: none;
        }
    </style><?php
}

This is focused on images, but you can add anything to it…

Method 4

I know it’s a really old question, but I was looking for a feature like this right now, and @Jake ‘s answer was the closest to the solution I got myself, which is adding to the style.css

.media-sidebar .setting.has-description,
.media-sidebar #alt-text-description,
.media-sidebar .setting[data-setting="title"],
.media-sidebar .setting[data-setting="caption"],
.media-sidebar .setting[data-setting="description"],
.media-sidebar .setting[data-setting="url"],
.media-sidebar .media-types.media-types-required-info,
.media-sidebar .compat-item {
    display: none !important;
}

this removed the whole meta fields part, leaving image details like file name, image size and upload date.

Method 5

The sanchothefat’s Answer is correct, really Works like a charm.

Just for increase his answer, you can use unset( $form_fields['image_alt'] ); to remove the Alternate Text.

Thanks for Answering sanchothefat, it Helped me.
