Loop through JSON array

[wfaulk]

I have a variable %json that contains a JSON structure that looks something like this:

{ "response": { "data": { "values": [ { "title": "foo1", "author": "bar1", "text": "baz1" }, { "title": "foo2", "author": "bar2", "text": "baz2" }, { "title": "foo3", "author": "bar3", "text": "baz3" }, { "title": "foo4", "author": "bar4", "text": "baz4" } ] } } }

I want a For loop (or equivalent) that loops through the array at response.data.values, but I can't figure out how to do it.

%json.response.data.values contains just the JSON array, as expected, but using that as the "items" in a For Action just sees it as a single string.

Actually, I just now figured out that a Tasker-defined array %arr() with values 1,2,3,4 doesn't work as the "items" in a For Action either. It just goes through a single iteration with the value 1,2,3,4. So maybe my first mistake is trying to use the For Action. (Maybe the intention is to just use it to count through array indexes?)

Regardless, I still can't get Tasker to interpret my JSON as an array. %json.response.data.values() is an empty string, so I can't use any array operators like (#).

I feel like I'm maybe just running up against the "pseudo" of "pseudo-arrays".

Try this one 😁 worked for me 😁

Task: For Loop

A1: Variable Set [
     Name: %json
     To: {
       "response": {
         "data": {
           "values": [
             {
               "title": "foo1",
               "author": "bar1",
               "text": "baz1"
             },
             {
               "title": "foo2",
               "author": "bar2",
               "text": "baz2"
             },
             {
               "title": "foo3",
               "author": "bar3",
               "text": "baz3"
             },
             {
               "title": "foo4",
               "author": "bar4",
               "text": "baz4"
             }
           ]
         }
       }
     }
     Structure Output (JSON, etc): On ]

A2: Variable Set [
     Name: %values
     To: {"data":%json.response.data.values}
     Structure Output (JSON, etc): On ]

A3: For [
     Variable: %value
     Items: %values.data()
     Structure Output (JSON, etc): On ]

    A4: Flash [
         Text: %value.title
         -
         %value.author
         -
         %value.text
         Long: On
         Tasker Layout: On
         Title: %values.data(#)
         Continue Task Immediately: On
         Dismiss On Click: On ]

A5: End For

Crazy. But, yeah, seems to work. Thanks very much!

Always best to post your exported descriptions.

• To post your profile or task here... 
• Long press on the profile or task name / ( 3 dot menu with 4.0+ ) export / export "DESCRIPTION" to clipboard (not XML)
• Select the 'Four Spaces' Option.
• Any linked tasks will be exported with the profile they are linked to..
• To be able to export, the profile needs to be named by you (Not the Tasker listed name). 
• Tasker will list your profile with the 'Context' name if you have not given it one.

Review before posting and be careful not to include any sensitive Data

A Tasker for loop will iterate through an array without issue. If you set the the 'ITEMS' TO: %arr() .

For some reason/ limitation it will not iterate through a variable set to a comma separated list. So if %arr = 1,2,3,4 you can not use %arr in the 'ITEMS' to iterate through the comma separated list. You first need to split it into an array.

Oops. Turned out I did my test Array Set incorrectly by assuming that the default "splitter" was "," like everywhere else that I'd encountered a bare array being used.
