Disable image attachment links

2 Views

Is there a way to disable image attachment links trought a filter in functions.php or something ? I know it’s possible to do it manually when you add an image to a post but I want to disable this functionality by default.

What I want to do is set the “Link URL” option to “none” and remove / hide it from the upload attachement screen.

enter image description here

Is there a solution to hook into the “media-upload” “pop-in” ?

Thanks by advance.

  1. If anybody is interested in do the trick, my solution is this:

    function remove_media_link( $form_fields, $post ) {

        unset( $form_fields['url'] );

              return $form_fields;

}

add_filter( 'attachment_fields_to_edit', 'remove_media_link', 10, 2 );

  2. Go to-> http://yourblog.com/wp-admin/options.php

    Search for: image_default_link_type

    Change Value to: none (available options are none, file [links to the file itself], post [links to the post the image is related to], attachment [links to the attachment page with the image on it])

    or set it in your functions.php via (same options available as mentioned above)

    update_option( 'image_default_link_type', 'none' );

  4. I think you would have to edit the loop-attachment.php in your theme, specifically lines 50-61:

    if ( wp_attachment_is_image() ) {
                                echo ' <span class="meta-sep">|</span> ';
                                $metadata = wp_get_attachment_metadata();
                                printf( __( 'Full size is %s pixels', 'twentyten' ),
                                    sprintf( '<a href="%1$s" title="%2$s">%3$s &times; %4$s</a>',
                                        wp_get_attachment_url(),
                                        esc_attr( __( 'Link to full-size image', 'twentyten' ) ),
                                        $metadata['width'],
                                        $metadata['height']
                                    )
                                );
                            }

    Pretty sure commenting out this whole block will achieve what you want. Haven’t tested it myself though.

  6. Here is the basic php function that you would need to insert into your theme’s functions.php file:

    <?php
function lose_attachment($content){
return preg_replace('/<a(.*?)href="(.*?)/attachment/(.*?)"/i', '<a$1href="$2"', $content);
}
add_filter('the_excerpt', 'lose_attachment',2);
?>

    This will remove the ‘attachment/name-of-image-file’ part from the URL making it link to the post’s permalink itself.
