$input with multi-dimensional arrays

[FlorianA]

Hi all,

could it be that input()->post does not cope with multi-dimensional arrays from POST data?

Example data (pasted from Firefox network analysis):

{
	"add[91896][]": [
		"30227",
		"30312"
	],
	"add[89364][]": "30430",
	"nr[91896][30227]": "a",
	"nr[91896][30312]": "b",
	"nr[89364][30430]": "c",
	"nr[91896][30332]": "",
	...
}

My code:

        print "===add=== "; print_r($_POST['add']);
        print "===nr=== "; print_r($_POST['nr']);

        print "===add=== "; print_r(input()->post('add'));
        print "===nr=== "; print_r(input()->post('nr'));

Result:

===add=== Array ( [91896] => Array ( [0] => 30227 [1] => 30312 ) [89364] => Array ( [0] => 30430 ) ) 
===nr=== Array ( [91896] => Array ( [30227] => a [30312] => b [30332] => [30389] => [30364] => [30432] => [30208] => [30403] => ) [89364] => Array ( [30430] => c [30332] => [30350] => [30389] => [30384] => [30432] => [30403] => ) ) 

===add=== Array ( )
===nr=== Array ( ) 

Any ideas what could be wrong?

Unfortunately, PW only supports one dimension for arrays when using the API to process data.

There's been some discussion on this topic at GitHub: https://github.com/processwire/processwire-issues/issues/387

OK, thanks for the link. So I'll use the $_POST variable.
