Field names using arrays

[Pete]

Hi folks

It seems like there's an issue with using arrays in field names. For example, when I submit this:

<input type="text" name="extras[$event->id][$extra->id]" value="1" />

and print the contents of $this->input->post versus printing the contents of $_POST I get different results as below:

// print_r($this->input->post) gives me this:
 
WireInputData Object
(
    [stripSlashes:protected] =>
    [data:protected] => Array
    (
        [extras] => Array
        (
        )
    )
)
 
// Whereas print_r($_POST) gives me this, which is what I want:
 
Array
(

    [extras] => Array
    (
        [1504] => Array
        (
            [1499] => 1
        )
    )
)

I'm happy to work with $_POST instead, but wondered if there was a reason why PW's version doesn't do multi-dimensional arrays from input fields?

@Pete: this is a bit old, but Ryan has explained it here. In that reply he also says that he'll add support for multidimensional arrays soon.. but as far as I can see, it's still expressly disallowed: https://github.com/ryancramerdesign/ProcessWire/blob/master/wire/core/Input.php#L62.

So.. good question
