About v:iterator.shift

[typo3ua]

I have array

array(3 items)
   0 => ''
   1 => 'Item 1'
   2 => 'Item 2'

I need to delete 0 => '' I added {array -> v:iterator.shift(as: 'foo') -> v:variable.set(name: 'too')} ...and I get the same

array(3 items)
   0 => ''
   1 => 'Item 1'
   2 => 'Item 2'

What is wrong?

The iterator.shift viewhelper does not change the input data, it merely returns the value of the first element.

https://github.com/FluidTYPO3/vhs/blob/development/Classes/ViewHelpers/Iterator/ShiftViewHelper.php#L17

Shifts the first value off $subject (but does not change $subject itself as array_shift would).

If I'm correct, in your code the variable foo should hold the value of the first array element, i.e. an empty string '', whereas the text output of the whole operation (none, an empty string again) is set in the variable too. The variable array is unchanged all the time.

You might want to have a look at iterator.slice.

Hello, @tantegerda1

You might want to have a look at iterator.slice.

Thank you for reply... can you give me an example

[typo3ua]

{v:variable.set(name: 'arr', value: '{0: \'\', 1: \'Item 1\', 2: \'Item 2\'}')}
{v:iterator.slice(haystack: '{arr}', start: 1, length: 2) -> v:variable.set(name: 'foo')}

Thanks! I did it...
