Split image field URL and display in PDF

Hi,

I have an image field named "EvidenceImages" that has two or more images.  When I go into Globiflow and get the value of "EvidenceImages", it presents comma separated value like this: 

https://files.workflow-automation.podio.com/127-55671-image1.jpg, https://files.workflow-automation.podio.com/127-48569-image2.jpg

What I am trying to do in globiflow is use a custom variable so when I use it to create PDF it passes separate HTML image paragraphs to insert the images and by the end get something like this:

• image1 = https://files.workflow-automation.podio.com/127-55671-image1.jpg
• image2 = https://files.workflow-automation.podio.com/127-48569-image2.jpg

Does anyone know or have any code to split this comma separated array so I can display img tags around them to display?

I already tried explode(",", EvidenceImage(Public URL)) and looks to create an array, and when I tried array_slice(explode(",", EvidenceImage(Public URL)),0) to get the first image URL doesn't get anything.  

Many thanks

  Hi Luis,

  simply do:

  image1 = explode(",", EvidenceImage(Public URL))[0]
  image2 = explode(",", EvidenceImage(Public URL))[1]

  If you want to use array_slice() in PWA you must combine it with current():
  current(array_slice(explode(",", EvidenceImage(Public URL)),0))
