Dynamic Image Variant in Template












3















I'm keen to set my image variants dynamically from content editor and not quite sure how I do this in twig.



I have three variants. They are named imageVariantsThumb, imageVariants16by9, and imageVariants3by2 in craft.



To render the variant on the image I use the following.



{% set optimizedImages = item.itemImage.one().imageVariantsThumb %}


Depending on the dropdown selected in the editor (say the values are thumb, 16by9 and 3by2) I want to change the variant name in this line of code. How do I use the value from my drop-down field to change the variant name on the end of the code above?



I have tried defining a variable using the value and replacing imageVariantsThumb above but it doesn't work:



{% if block.listImageRatio == '16by9' %}
{% set imageRatio = 'imageVariants16by9' %}
{% endif %}

{% set optimizedImages = item.itemImage.one().imageRatio %}

          So instead of using the dot syntax ., this would be a good place to use the subscript syntax .



          {# dot syntax #}
          {{ foo.bar }}

          {# subscript syntax #}
          {{ foo['bar'] }}


          When you use the subscript syntax to access a variable's attributes, you can safely use variables (by just removing the single quotes surrounding the attribute).



          {% set bar = 'helloWorld' %}
          {{ foo[bar] }}
          {# functions just like foo.helloWorld #}


          So for your example, you would do this:



          {% if block.listImageRatio == '16by9' %}
          {% set imageRatio = 'imageVariants16by9' %}
          {% endif %}

          {% set optimizedImages = item.itemImage.one()[imageRatio] %}
