Link images to post permalink – custom post types

3 Views

When someone creates a post in a custom post type and uploads an image the Link URL box shows it as the attachment URL. What I would like is for it to be the permalink to the post. Is there a way to do it without modifying core files?

  1. Thanks for answering the comments and thanks to @בניית אתרים providing the screenshot; now I have a better idea of what you wanted.

    Based on what you asked for I think what would be ideal would be for the dialog box to simple generate your preferred URL; that way you don’t have to remember to click. You can accomplish what you are after by using the 'attachment_fields_to_edit' hook and modifying the sub-elements of the passed array: $form_fields['url']['html'].

    You can copy the following code to your theme’s functions.php file, or to a .PHP file for a plugin you might be writing:

    add_filter('attachment_fields_to_edit','your_attachment_fields_to_edit',10,2);
function your_attachment_fields_to_edit($form_fields,$post) {
  $url = get_permalink($post->ID);

  /* UNCOMMENT THESE LINES IF FOR PARENT POST URL AND NOT ATTACHMENT POST URL
  $url_parts = explode('/',trim($url,'/'));
  array_pop($url_parts);
  $url = implode('/',$url_parts) . '/';
  */
  $form_fields['url']['html'] =<<<HTML
<input type="text" class="text urlfield" name="attachments[{$post->ID}][url]" 
       value="{$url}" />
HTML;
  return $form_fields;
}

    Here’s what it looks like with the commented-out code so that the full permalink to the attachment post shows:

    Note that one caveat is this only works after you have saved the parent post because the permalink is evidently not finalized until then. I’m sure there’s a workaround but I’ll leave that as an exercise for the reader (like my professors used to say…)

    P.S. I simultaneously love your domain name, and I feel quite queasy about it at the same time! 😉

  2. On the media uploader, Once an image is uploaded , before you click the “insert to post”
    you need to click the “none” button under link url.
    here, they say a picture is worth a 1000 words:
