How to use an array variable in an Apply to each loop in a Item() function?

[itscoldoutside]

items('Apply_to_each_4')['attachments/f_1photoa']?[0]?['url'] - This allows me to get the url from my array.  

I would like to make the f_1photoa a variable stored in another array.  When I add the variable to my ITEM() function, it treats my items('Apply_to_each_4') as a string and not an item function.  

How can I loop up a item() using a variable?

Hi , @itscoldoutside 

According to your description, your ['attachments/f_1photoa'] is an array in json. Do you mean you want to use the Item() function to get the url in this array ?
Here are the steps you can refer to .
This is my test json:

This is my flow:

The first compose action is used to created this test data:

json('[
{
  "attachments":{
    "f_1photoa":[
      {"url":"https://wwww.123.com"},
      {"url":"https://wwww.234.com"},
      {"url":"https://wwww.456.com"}
      ]
    
  }

}
]
')

The apply to each action:

Then we can use the select action to put the url in an array and we can use the Apply to each action to use the item() function to loop.

If I misunderstand what you mean, you can describe your needs and your expected outcomes in detail so that we can better help you.

Thanks for the reply, let me clarify.  My json looks like this:

I am able to pull the url for each one by using:

I would like to use a defined array to loop through the Get attachments function:

f_1photoa, f_1photob, f_1photoc all have the same schema so I can list loop through using the get attachments function.  Right now when I try to join the Item(apply_to_each) and ['attachments/f_1photoa']?[0]?['url'] it joins the literal json string to ['attachments/f_1photoa']?[0]?['url'] and does not treat it as one item().

Thanks.

Hi, @itscoldoutside 

Thanks for your quick response ! According to your description, do you mean you want to get the three urls to an array for loop in your json return? I test it in my side , this is my test json:

We can create an array variable like this:

Then we can get the result as follows:

I'm sorry if I misunderstood what you meant! If you can, you can provide me with some test data and the results you want, so that I can better help you and understand your needs！

This is close, but would like to accomplish what you are using with an array of photo name variables.

Where Current Item is the item from attach_name.  So f_1photoa, f_1photob, f_1photoc are dynamic from the array loop.

Hi , @itscoldoutside 

Thanks for your quick response! Here are the steps you can refer to , this is my flow:

outputs('Compose')?['attachments']?[item()]?[0]?['url']|

Then we can get the url in each loop:
