Relative Root URL's

I am using a relative root url plugin which works great, but causes issues with the admin and user emails sent out by GF because the links to images and files in the email are not absolute. I want to continue using the relative root URL's and I am wondering if there is a way I can somehow filter the email message running a function in functions.php, or the best way to modify the HTML to make the URL's absolute again. I am comfortable putting together the URL replacement, I just need to know where to hook in or filter to do so.

I have tried output buffering which does not work...

Thanks,

Hi Chris,

http://wordpress.org/extend/plugins/root-relative-urls/

This plugin modifies the URL before it goes into the DB on any uploads, so it doesn't modify the message on output, it has already rewritten the url to /wp-content/uploads/etc/

I can remove the relative URL's plugin, but it is nice to have for moving from staging to live. Also, it would be nice in general to be able to filter / modify the message sent programmatically.

Thanks,
Cameron

Yes, the entries are modified to relative URLs before they are inserted into the DB.

Image and file urls are both of concern in the notification emails (images are broken, file paths are not able to be followed).

I am comfortable rebuilding those URLS with some regex / preg_replace magic in functions.php or in a plugin, but I am not sure if there is a hook or filter to use to edit the admin notification message string.

Any ideas on how to change that message programmatically with a hook? I don't want to hack at core files.

Thanks much,
Cameron

Hi Chris,

On further inspection I found that it was not actually the core root relative urls plugin that was causing the issue (I disabled and even deleted it).

I am dynamically setting the content URL in wp-config.php with the following:
define('WP_CONTENT_URL', '/wp-content');

This works great with all images and files (and requires and such) but causes issues with the GF forms notifications because it is saving as:
/wp-content/uploads/gravity_forms/1-acc4bf57bc9efeed64d056171a8e757b/2013/01/filename.pdf

Do you have an example of a hook that I can reference that manipulates the form data prior to saving to the database so that I can change the URL of the file that gets saved to wp_rg_lead_detail?

Thanks for your help, I assume this is something others have encountered as using relative urls is pretty important in having a development environment.

Thanks Chris, I will give that a shot, it's not ideal because it would still bake the URL into the file upload reference so testing uploads on a dev environment would cause the wrong URL to be linked on the live environment.

Just to be clear also, it's actually not the root relative urls plugin at all, but the
define('WP_CONTENT_URL', '/wp-content');
in the functions.php that is causing GF to not absolutely link the URL's correctly (in email only, relative reference is fine in the backend for file downloads). Most users don't touch it, but some may want to redefine the location of that folder to name it simply "content" or "_web_contents" (to put it at the top of directory in sort by name) using that WP_CONTENT_URL constant. It seems that GF should account for this in how it creates the links for the email notifications to handle these standard WP config settings.

I even tried a plugin that pushes all files uploaded through WP media uploads to Amazon S3 and those all work correctly, but not GF uploads; so I presume GF uploads are handled differently than the default WP upload methodology.

Is there no other way to manipulate the email messages sent by GF than hack at core files? (it would be much easier to edit the message output than modify and deal with absolute URL's and adding pre-submission filters to each file upload field.) Plus this would keep things more server agnostic.

Thanks for all your help!
Cameron

P.S. if I were to take the time to figure out how to setup the url replacements in a WP and GF friendly fashion would you consider reviewing the code for potential future use? I'm sure others would see benefit from this as well.

Sound great, thanks Chris!

Thanks Chris, that does the trick!

Here's what I ended up with in case it helps someone else (in functions.php):

add_filter("gform_upload_path", "change_upload_path", 10, 2);
function change_upload_path($path_info, $form_id){
   $path_info["path"] = "wp-content/uploads/gravity_forms/";
   $path_info["url"] = 'http://'.$_SERVER['HTTP_HOST']."/wp-content/uploads/gravity_forms/";
   return $path_info;
}

Now the paths are pushed into the DB with the absolute URL path and they work correctly in the admin emails (URLs are specific to the server they are uploaded on now which is less ideal, but they work).

I appreciate your time and help finding this solution.

Cheers!
Cameron
