AddThis need to share custom url generated by js

Question

I need the facebook/twitter/email buttons to share the page with the photo loaded. The script for the photo form was written years ago by a colleague that has left and I have concluded that it is something I am not able to customize myself. I have included as much info as I could think of. Thanks!

EDIT: I can provide wp login details for anyone that would like to take a stab at this for me. Very much appreciated!

1. Go to this page: etncal.staging.wpengine.com/community-event-photos/
2. Enter ID# 09070073, click Get Photo button
3. New page loads and the url will read: etncal.staging.wpengine.com/download-your-community-event-photos/?photo=090700731381779074495
4. A parameter has been passed to url and the photo code entered is the first 8 digits
5. Share this buttons are linking to the page url without parameter - so the blank page without the image loaded is being shared. Need to share page with unique url & photo.

Community Event Photo form uses two pages:

1] Page with form: etncal.staging.wpengine.com/community-event-photos/

Code added to body of this page:

[js]varUnique=new Date().getTime() //will always be unique
function CheckForm() {
var photoID = document.photoForm.photoID.value;
var numericExpression = /^[0-9]+$/;
var eightdigit = /^\d{8}$/;
if(photoID.match(eightdigit)) {
var urlID = (photoID.concat(varUnique));
var newURL = 'http://etncal.staging.wpengine.com/download-your-community-event-photos/?photo=';
location.href=(newURL.concat(urlID));
return false;
} else {
alert('Please enter the eight digit number for your photo ID.');
return false;
}
}[/js]

2] Page that loads image: etncal.staging.wpengine.com/download-your-community-event-photos/

Code added to body of this page:

<div class="clear-mg"></div>
<div class="photo">[js]
displayPhoto();
[/js]</div>

Link to the following js file is included in header of same wordpress page (click on 2nd button to right of Add Media, using a plugin to add): etncal.staging.wpengine.com/wp-content/themes/canvas_child/js/photos.js

PHOTOS ARE LOCATED HERE: etncal.staging.wpengine.com/wp-content/themes/canvas_child/images/community/photos/

Answer 1

The problem is that you're setting the addthis:url parameter to a different value from the address bar. Here's the code on your page:

<div addthis:url='http://etncal.staging.wpengine.com/download-your-community-event-photos/' addthis:title='Download Your Community Event Photo ' class="addthis_toolbox addthis_default_style addthis_32x32_style">
    <a class="addthis_button_facebook"></a>
    <a class="addthis_button_twitter"></a>
    <a class="addthis_button_email"></a>
</div>

You need to set the addthis:url parameter to the URL of the photo page or set your tag to the URL of the photo page.
