Form validation in 4.1.6 raises type error - sjender - 01-05-2022

Hi,
I used the form validation library to validate a form containing arrays.

Code:
<form>

<input type='text' name='date'>

<input type='text' name='invoice_rule[1]'>

<input type='text' name='invoice_rule[2]'>

......

<input type='submit'>

</form>

I had the following validation rule:

PHP Code:
'invoice_rule' =>  ['rules' =>    'numeric', 'errors' =>    ['numeric' => 'Not numeric']] 

This worked fine and walked through all the invoice rules.
But now it raises an error "Argument 1 passed to CodeIgniter\Validation\FormatRules::numeric() must be of the type string or null, array given".
I looked at the changelog and indeed, this is one of the changes...
But how am I supposed to validate each element of the array?
I don't want to foreach it, because it makes the code less readable.

Never mind.... already found it.
Typing this message took me longer than reading the manual. LOL.
invoice_rule.* did the trick!
