Remove the first 3 objects in an array

liam

I have 10 objects in an array and i want to remove the first 3 object in the array without any condition.

How do i do this ? i've search the docs and forum but could not find the solution.

dorilama

Have you tried with a "range" filter?

The documentation is here: https://docs.xano.com/working-with-data/data-type-filters/array-filter

In your case it would be start 4 and end 10.

Let me know how it goes

@dorilama hmmm this requires us to know the length of the array first right ?

what if i don't know the array length ?

it can be 10 objects or 5 objects or 100 objects in array. We need to remove the first three element from that array

dorilama

the filter "count" returns the number of items in an array

@dorilama this is how my array looks like this

{"instagram_feeds":[

{"id":"2885669349228547921","type":"GraphVideo","likes":200,}

{"id":"18271872364637463744","type":"GraphVideo","likes":7361,}

{"id":"918291829172918218223","type":"GraphVideo","likes":71161,}

{"id":"62520471524457291283","type":"GraphVideo","likes":261,}

{"id":"012891278172817212333","type":"GraphVideo","likes":161,}

{"id":"09871625182447823783","type":"GraphVideo","likes":741,}

]}

we want to remove the first three objects, is this still possible with range ?

dorilama

Yes, it is possible.

I'm from my phone now but you can read in the docs:

Returns array of values between the specified start/stop.

If you don't know the length in advance tou can use the filter "count" to get it.

Give it a try and let me know how it goes.

Hi @ilam It would be great if you can elaborate the use case as well,

According to the above comments I would say :

Get the total number(Count) of object in an array(check if there is any object or not), if there is any object available -> compare the count of object with 3 -> if <=3 delete all else delete first three using 'Range' Function(Specified range will start from 4 and end at 10) like @Dorian A elaborated above.

Give it a try, it should work.

dorilama

@Sahira_Mehta "range" will not delete the items from the array, it will select and return the items in the range

Sahira_Mehta

@dorilama oh mybad, I mistyped it, lol!

I meant use "Range" to select the items from the array and then remove the first 3 items

Thank you letting me know @dorilama and Happy new year buddy! :)
