Here's my situation. I want to use a modified version of the WordPress Press This bookmarklet to pass the current page URL to a custom field on my post. In this case, let's say my custom field is linked_list_url.

I'm guessing there are four pieces to this:

  • Add a custom input field to the page generated by the bookmarklet
  • Grab the URL of the page the bookmarklet was used on and store it
  • Pass the stored URL to the custom input field
  • Pass the contents of the custom input field to WordPress, setting it as the key for the custom field

I've modified the bookmarklet to have a custom input field and it's pulling the URL off of the page and passing it to the input box, but when I submit the bookmarklet, nothing is passed to WordPress.

Here's my press-this custom bookmarklet: http://pastebin.com/UjNkpNrE

Specifically: Once I have the URL passed to the custom input field in the bookmarklet, how should I go about having the contents of that field passed to WordPress into the custom field linked_list_url?

    Maybe this will help? wordpress.mfields.org/2010/bookmark-this re: hooking into admin_head-post-new.php and setting a custom field value based on a parameter passed in the query string... – goldenapples Jan 6 '11 at 3:11

    Are you modifying the core /wp-admin/press-this.php file to achieve this? Because it's not a good idea to change core files, you should try to find a hook to do what you want from a plugin file, so you can survive upgrades. I think your first three steps are solved in the _wp_http_referer form field, and you can solve step four in the wp_insert_post hook. – Jan Fabry Jan 10 '11 at 8:48

Not sure if you're still looking for an answer, but I wrote a plugin to take care of this: http://yjsoon.com/dfll-plugin

I'm not sure if your using linked_list_url means you're already using the plugin, but if you are, I just updated it. :)
