I have setup a global set for images i use across the site. I have one for seo - where I have images for a twitter card and Facebook image in my seo settings. There is only one image for each field ( so hoping to avoid using the array syntax )

Two questions:

  1. I am not sure how to access the images uploaded into this global variable. My global set has a handle "seo" and the image's handle is "twittercard". This isn't working :

    meta(name='twitter:image:', content='{{ image.getUrl('seo.twittercard') }}')

  2. Is this the most efficient way to store images used globally across the site? ( via global image variables?)

seo.twittercard is an ElementCriteriaModel. To access the actual asset, you need to use seo.twittercard.first (or equivalently: seo.twittercard.first()).

However, you should always check that this exists before referencing it:

{% if seo.twittercard|length %}
  <meta(name='twitter:image:', content='{{ seo.twittercard.first.getUrl() }}')>
{% endif %}

And yes, this is a fine way to store images used globally across the site.

  • What is the benefit of doing the check ( if the image exists?). I am hoping to simplify the code by doing something like this ? meta(name='twitter:image:src', content='{{ image.getUrl('seo.twittercard.first') }}') – user2022284 Aug 14 '15 at 18:30

    The image might not exist. It might not have been initialized, or the asset might have been removed. And then your site will be mysteriously broken. I think it is always worth checking. – Marion Newlevant Aug 14 '15 at 18:49
  • Thx. Will do then. However, I tried to see if i can simply output the url on the template ( before putting it in the wrapper to check if it exists ). this is not working: {{ image.getUrl('seo.twittercard.first') }}') – user2022284 Aug 14 '15 at 18:53

    oops! fixing my answer. You want {{seo.twittercard.first.getUrl()}} – Marion Newlevant Aug 14 '15 at 19:00
  • boom! works nicely! Thx. – user2022284 Aug 15 '15 at 3:13
