I want to add some inline help to the New mailing CiviMail. e.g. show a block on this page civicrm/a/#/mailing/12345

I've created my drupal block, set it to appear in the correct theme and set it to only display on this page: civicrm/a/#/mailing/*

However for some reason it won't show. I've backtracked and I'm able to get it to show up with this expression: civicrm/* but as soon as I add civicrm/a/* it doesn't work, just doesn't display

Any ideas about why this might be?

Thanks Peter

I think this may have something to do with the fragment identifier (#). This is typically used to link to a particular point within a page (an anchor). However, in this case I think it is being used by the JavaScript framework to indicate a particular page view. I guess that Drupal may not be able to process URLs like this.

  • hey @William - have you had a chance to reproduce this? As the CiviCRM project is transitioning to AngularJS for all forms - we may need to rethink the # in its urls May 18, 2016 at 13:33
  • @KarinG-SemperIT I haven't looked into this myself but it would be worth checking it out. Perhaps best to avoid the # if possible? May 18, 2016 at 14:34
  • I think you're correct - voted you up! And added a possible immediate workaround for Peter. May 18, 2016 at 17:26

I think @William is correct - I just tried and I can't get a Block -> Visibility -> Pages -> Show block on specific pages -> Only the listed pages -> to show up on a #a URL (tried escaping the # - can't do it). civicrm/a* works - but then you'd be seeing it on all forms using AngularJS.

That's not good! Let's search JIRA CiviCRM for it - and if needed report it. I did have a client run into using #a on iOS/Safari - workaround at that time for to use Chrome - but this is a bigger issue.

Possible immediate workaround [I know not ideal] I suspect that you only have few people who can CiviMail -> put them into a Drupal Role of their own -> then:

  • use Region settings to only show this block to your staff in the CiviCRM theme
  • use visibility settings -> Roles -> Show block for specific roles

Agree with Williams' description.

Other possible resolutions:

  1. Give some love and patience to planned updates for the form system. Right now, Angular pages are strictly SPA ("single-page architecture" -- "javascript handles the page routing") and they're not very hookable. Current plans for the next iteration provide more hookability and reduce the reliance on SPA. (Somewhat related: https://forum.civicrm.org/index.php?topic=36978.0 )
  2. Target the block at the base page civicrm/a. In the code for your block, use some Javascript to call setInterval() and periodically check window.location.hash; hide or display the desired block with $.hide() or $.show().
  • Increase hookability for AngularJS forms: cool; yes I would love that! Ad 2: many Drupal blocks are not generated in code though - we must retain some way for Drupal blocks to be displayed via the Drupal Core -> structure -> blocks GUI - esp if we get to building public Contribution pages with AngularJS - b/c there you'd typically get all sorts of Drupal blocks added to such a CiviCRM page: like eg social media block; search block etc May 18, 2016 at 23:06
  • Idle curiosity - any reason that the existing architecture of angular pages didn't include different urls? Would it be super difficult to just add in an extra path component after the /civicrm/a/ that is ignored by the angular code?

  • That might work for some use-cases. FWIW, though, it would only display Drupal blocks that match the original path; when you navigate among different Angular routes (e.g. civicrm/a/#/abtest => civicrm/a/#/abtest/new => civicrm/a/#/abtest/1), that navigation is all client-side, so it would never ask Drupal to rerender the list of blocks.

Taking this in a slightly different direction - it reminds me that in general, CiviCRM urls are not very nice when it comes to Drupal, because Drupal doesn't like to pay attention to query strings. I wonder if there is a broader solution that also deals with this issue? I'd imagined that there's a simple Drupal hook that could so some rewriting in and out.


I haven't tried this so don't know if it will work. But, I create URL aliases for my civicrm contribution pages so that when a user goes to those pages it's a nice pretty url instead of the long civicrm url. I wonder if creating a URL alias in Drupal and then using that alias as the URL for the Show only on this page would work?

  • Unfortunately, that will not work - for the same reason (the # in the URL). Also for a new mailing screen - you can't URL alias that as unlike stationary contribution page URLs the id is generated as you create the new mailing: civicrm/a#/mailing/776 and then civicrm/a#/mailing/777 etc. May 19, 2016 at 19:09
  • I didnt think about the id's changing. blah.
