Tokens and Variables

The following tokens and liquid variables can be used in a variety of locations throughout the site, but primarily on course-related pages and static pages (e.g. home page). They are not, unless specified otherwise, supported elsewhere (e.g cases, articles or multiple-choice question, user biography etc...)  

IMPORTANT NOTES:

  • all the tokens below are listed with spaces between the {{ and the token. This is so that this page does not attempt to render them. When using all these tokens, do not use space between {{ or }} and the token. 
  • beware of copy-pasting these token as invisible style markup will stop these working. Clear text formating (Tx) in the tool bar to fix them if they are not working. 
  • site permissions are listed here (access limited)

On this page:

 

Article

back to top

  • embed (part of) an article
    • token: {{ article:<id> }} Embed an article
    • available in: courses
    • e.g. {{ article:pituitary-gland }} = embeds whole article
    • e.g. {{ article:pituitary-gland,gross-anatomy }} = embeds from “gross anatomy” title to end of article
    • e.g. {{ article:pituitary-gland,gross-anatomy,relations }} = embeds from “gross anatomy” title and ends just before the “relations” title
    • e.g. {{ article:pituitary-gland,top,relations }} = embeds from top of article and ends just before the “relations” title

Awesound

  • embed audio - this has been removed

Boxed Text

back to top

  • Available in: courses, restricted pages and pages
  • Styles: A variety of styles are available (see below) which broadly match /patterns
  • Opened/closed: If 'initially' is specified as "opened" or "closed", the panel is collapsible; otherwise it is not.
  • Just heading: If no panel body is being supplied, use {{ begin_box_text_header:no_body}} instead of {{ begin_box_text_header}}, to ensure the borders render correctly.
  • Countdown: Adds a countdown timer in the box header to countdown to the next event in the live schedule, use {{ begin_box_text_header:countdown=event}}
  • Sample use follows

{{ begin_box_text:style=info&initially=opened}}{{ begin_box_text_header}}Heading{{ end_box_text_header}}{{ begin_box_text_body}}Body text goes here{{ end_box_text_body}}{{ end_box_text}}

The source code should look like this (note the <p>..</p>):

{{ begin_box_text:initially=opened&amp;style=warning}}{{ begin_box_text_header:initially=opened}}Important{{ end_box_text_header}}{{ begin_box_text_body}}

<p>XXXX.</p>{{ end_box_text_body}}{{ end_box_text}}

Case

back to top

  • embed a case study
    • token: {{ case_study:<id>,<parameter1>,<parameter2>,etc..}} 
    • note: this is the study ID not the rID. You can find this by looking at the URL of the case in presentation mode or go to the study, right-click on the study header and “inspect element” and then search for "study-desc"

  • parameters available (can be combined) - this restricted page (available only to some users) has examples of each
    • can_download
    • logged_in
    • show_annotation_tool
    • show_findings
    • show_findings_text_only

  • {{ case:<rid>,publication_date }} e.g. 24 Janunary 2023

 

 

Certificates and CME

back to top

Old certificate

  • URL is as follows: https://radiopaedia.org/users/frank/courses/abdominal-emergency-radiology-course-online/certificate
  • note: this is just the link a user has in their radiopaedia.org/my/courses tab with the `.pdf` extension removed. This will go to a landing page with links to their courses page. 
Certificate on courses and restricted pages

The certificate generate button which calls a certificate template with or without text and input claimed number of points can be added using the following: 

  • {{ certificate:<template_name> }} = generates just the button. The template name should be lowercase with underscores. i.e if the name is Standard Template, it should read {{ certificate:standard_template }}

  • available parameters to be added after <termplate_name>?parameter1=x&parameter2=Y etc...

  • text_for_input - replaces Standard formatted AMA text with any text you want

  • credit_max=8 - set max number of credits to 8

  • credit_max=duration - uses duration of the restricted page to calculate max time (use with credit_step=0.25)

  • credit_step=0.25 - rounds duration down in 0.25 credit (15min) blocks

  • multiplier=1.3333334 - multiplies duration by 1.333334 before rounding. 

Both credit_max and credits claimed from the input box will be passed back to the certificate template. 

Multiple certificates per course

Sometimes a course will have multiple restricted pages and only a single certificate at the end (e.g. a learning pathway). Other times multiple restricted pages will each have a certificate (e.g. case reads). The way {{ if:certificate_generated}} is evaluated depends on the {{ }} tags contained by the certificate template. 

If the certificate template includes any {{ course...}} tag then {{ if:certificate_generated}} will be TRUE if any certificate has been generated for the whole course (i.e. multiple certificates will not work). 

If the certificate template does NOT include and {{ courses....}} tags, then it will be evaluated only against the restricted page it is on, and therefore multiple certificates are possible. 

 

Certificate templates
  • Most (all?) the user tokenscourses and restricted page tokens and conditional tokens work but depending on where they are used they may lead to unpredictable responses.
  • {{ cme_attribution }} generates AMA PRA Category 1 Credits ™ (including italics and TM) 
  • {{ credits_claimed }} available if

  • {{ credits_max }}

  • {{ text_input:description }} is used for one-off certificates for custom text e.g. "text_input:month and year e.g. January 2024"

  • {{ current_case:title }}

  • {{ current_case:rid }}

  • {{ current_case:author }} full name (first, middle, surname), without title or qualifications

  • {{ current_case:doi }} e.g. https://doi.org/10.53347/rID-182123

  • {{ current_case:publication_date}} e.g.  24 January 2023

In the sections of the certificate that are "Cormorant" font (First line, Paragraphs 1 and 2 and below timestamp and signatures) italics and bold are available as HTML <i></i> and <b></b>. These can be used in combination with tokens. 

Generate one-off certificates

You can generate one-off certificates using a template. When you click "generate" you will be prompted to supply all the data the template needs to complete the certificate and then the certificate will be stored against that user. 

 

Conditional display

Any of these tokens can be inverted using {{ ifnot: in place of {{ if.

Note: Failing to add an {{ endif}} after an {{ if}} will hide the remainder of the document.

Courses

back to top

  • {{ current_course:title }}
  • { date: whitelist_expires_on}} shows the date of expiry of the white list (AAP/free) 
  • there are a bunch of conditional statements relating to courses too: see above

 

Data protection

back to top

  • Show California DP popup https://radiopaedia.org/?snhbForceUser=CCPA&lang=gb
     

Dates

back to top

  • available in: courses only (including certificate and course emails)
  • confusingly, there are two separate systems for templating (one in the email section of courses and one for content) and therefore the variables have been implemented differently to match how they work
  • course content
    • {{ date:generated_on }} replaced with the date the page is rendered
    • {{ date:access_expires_on }} renders the date the current users access to a course will/did expire
      • to add an integer of days to date: {{ date:access_expires_on+10 }}
    • {{ date:accessed_on }} either the 'Certificate Availability' date or the date on which access was granted, whichever is later - note this will NOT work on restricted pages
    • for conditional date of access and expiry see conditional tokens 
    • {{ date:whitelist_expires_on}} - shows the date that all-access pass or free access expires
  • course email - without 'date:' in front of the token
    • {{ generated_on }} 
    • {{ access_expires_on }} 
      • to add an integer of days to date: {{ access_expires_on|add_days:10 }} 
    • {{ accessed_on }} 
  • Local Time
    • available in: courses and restricted pages
    • First parameter is the unix timestamp (number of seconds since midnight January 1st, 1970 UTC)
    • Second parameter, if provided, is the date format string (see https://foragoodstrftime.com/ for examples)
    • token: {{ local_time:1621224987:%A, %b %d}}

Direct Access Code

back to top

  • token:  {{ access_code }} inserts modal into public content section of course
  • available in: courses only
  • can grant access directly via url https://radiopaedia.org/courses/[course title]?access-code=[insert code here]

Headerless articles and cases

back to top

  • variable ?iframe=true
  • append ?iframe=true to any url and it removes the header and background
  • this is used in the iframe in quiz mode but third parties can also use this

Icons (font awesome)

back to top

Inserts "Solid" font-awesome icons with size based on font styling

  • {{ font_awesome:<icon_name>,<hex color>  }} 
    • icon_name is the name without the fa and with underscores (rather than hyphens)
    • e.g. fa-check-to-slot needs to be written as check_to_slot in the token
  • {{ font_awesome:circle_check,#76e46c }}

Here are some examples (restricted page) 

 

Images and icons

back to top

 

  • icons for use in course email section only
    • token: <img src="{{ 'image_name.png' | image_asset_url }}"></img>
    • note: just replace image_name.png e.g. <img src="{{ 'radiopaedia-logo.png' | image_asset_url }}"></img> from the list available images (see images for course emails)
  • hover to switch images - works only in pages whose URL is /courses
  • use: upload both images - same size
  • for examples visit this restricted page and copy source
  • IMPORTANT: be careful when adding this as there are unintended consequences
    • once added to a page additional <p class="hoverswitch "></p> are often added which cause rendering issues (review source) - easiest to edit in HTML editor e.g. https://code.visualstudio.com/

 

Product

back to top

 embed a purchase button or pricing table for courses

  • token: {{ product:<embed_token> }} 
  • token: {{ pricing_table:<embed_token>,<embed_token>,<embed_token> }} 
  • available in: courses
    • e.g. {{ pricing_table:nondoctor170,doctorhno320,doctorconsultant280 }}
  • for free indefinite access (such as for Help Learning Pathways)  then use price = 0 cents and {{ product: <embed_token> }} - this will generate a purple button only with the text of the button = to the "Description" text

Profile links

back to top

  • replace /users/[username]/ with /my/ and the link will prompt for user login and take the user to their relevant profile page including any filter applied
  • e.g. https://radiopaedia.org/users/frank/playlists?page=1&system=central-nervous-system&visibility=unlisted would become https://radiopaedia.org/my/playlists?page=1&system=central-nervous-system&visibility=unlisted
  • Each user profile tab can be thus referred to:
    • Profile: radiopaedia.org/my/profile
    • Cases: radiopaedia.org/my/cases
    • Playlists: radiopaedia.org/my/playlists
    • Edits: radiopaedia.org/my/edits
    • Favorites: radiopaedia.org/my/favorites
    • Courses: radiopaedia.org/my/courses

      • radiopaedia.org/my/settings#communication-and-permissions
      • radiopaedia.org/my/settings#password

Question

back to top

  • - embed a multiple-choice question
    • token: {{ question:<id> }} 
    • works in pages, restricted pages, courses, articles and even cases but there is little reason to use them in many of these locations. 

Restricted pages

back to top

  • {{ current_restricted_page:title }}

Restricted pages have a number of unique fields (at the bottom of the restricted page) that are available to them as tokens and conditional statements

  • {{ current_page:duration }} returns the duration in the Duration field in the Tags section as human readable. e.g. 00:34:24 will display as 34 minutes 24 seconds
  • {{ current_page:duration_credits?round_to=0.25 }} converts duration to CME credits (or hours) rounded down e.g. 5 hours and 23 minutes will be shown as 5.25 
  • {{ current_page:duration_credits?multiplier=1.333334&round_to=0.25 }} does the same as above, but first multiples the duration by a multiplier (for peer reviewer use 1.33333334 ). 
  • {{ if:current_page_tags=args_1,args_2 }} will match one or more tags. If multiple then treated as OR
  • {{ current_page:users?tag= }} (replaced deprecated {{ current_page:authors }}  )
  • {{ if:users_page_tags_include=tag }} (replaced deprecated { if: author_of_this_page }}   )
  • {{ if:current_restricted_page=1234 }} matches if the page being viewed is /pages/1234

 

Citation data
  • {{ current_page:citation_title}}
  • {{ current_page:citation_publication_date}}
  • {{ current_page:citation_author}}
  • {{ current_page:citation_conference_title}}
  • {{ current_page:doi}}
Tracking visits

When a logged in user visist a restricted page and stays on the page for >10s with the page being the focus of the browser it will be marked as visited. 

Logic:

  • {{ if:restricted_page_visited=<restricted page ID>}}
  • {{ ifnot:restricted_page_visited=<restricted page ID>}}

These can be used on the page itself or other pages. 

Icon/bullet:

An icon-formatted version that changes from an open circle to a green tick can also be used for multiple items (e.g. pages in a learning pathway).  The color can be optionally changed by the addition of an optional &color=#<hex> which will make both the circle and the tick the same color. 

e.g. 

  • Then some text and/or link
  • Then some text and/or link
  • Then some text and/or link

 

Multiple links or extra text or things just not working quite right?

The way this has been implemented each <li> item has exactly two child nodes (one of which contains the text and link). The result is that if you want the content after the tracking link to contain more than just one link and some text it needs to include a <span>. 

This includes a full stop after a link, like this. (see that full stop? it will break things) 

Generally, I think, Including <span> is going to be safer if you are doing anything fancy but NOTE: if you copy-paste from the WYSIWYG page then the span will not always copy, so copy from source is best. 

 

This one is correctly formatted

If you omit <span> it will break

Sidebar

Restricted pages also have a sidebar that can include e.g.

or an inclusion. These will render below the page on mobile. Background is light blue.
