Access repeater field values in form processing

[gebeer]

Hello,

I'm building a form through the API. In that form I am using a repeater field that is setup with 5 Ready-To-Edit New Repeater items. In the repeater is only one text input field named "servername".

Now I'm having trouble accessing the repeater field values when I process the form.

I read through the docs at https://processwire.com/api/fieldtypes/repeaters/. But when processing form input post values things seem to be different.

I add the field to the form with:

$registrationField = $fields->get("reg_servers")->getInputfield($pages->get("/registration"));
$registrationField->attr("class","form-control");
$registrationForm->append($registrationField);

The field is there in the form and working fine.

Now when processing the form, I need to access the values of my repeater.

Here's the relevant code:

if($input->post->submitregistration) {
    $registrationForm->processInput($input->post);
    $servers = $registrationForm->get("reg_servers")->value;
    var_dump(count($servers)); // this gives int 5, which is fine

    foreach ($servers as $server) {
        echo "<pre>";
        print_r($server->fields->servername); //servername is my text input field in the repeater
        echo "</pre>";
    }
    exit();
}

In the print_r output I can't find the value of my fields.

I also tried var_dump($server->servername) and var_dump($server->servername->value) inside the foreach which gives an empty string.

var_dump($server->fields->servername->value) gives null.

How can I access my field values?

Read this quickly. Just guessing here; are you by any chance dealing with a multi-dimensional array? If yes, then $input will not help. It is only set to deal with simple arrays. An option would be to use PHP's $_POST instead or there was some other nice code in the forums yesterday but I can't find it now  here you go if it is relevant. Anyway, just guessing for now but you will get better answers am sure

Thanks for that link kongondo. It really helped.

When I do print_r($GLOBALS), I get:

    [_POST] => Array
        (
            [name] => Test
            [uname] => test1
            [regemail] => my@email.net
            [pass] => 
            [_pass] => 
            [sort_repeater1708] => 0
            [publish_repeater1708] => 0
            [_disable_repeater1708] => 1708
            [servername_repeater1708] => 
            [sort_repeater1709] => 1
            [publish_repeater1709] => 0
            [_disable_repeater1709] => 1709
            [servername_repeater1709] => 
            [sort_repeater1710] => 2
            [publish_repeater1710] => 0
            [_disable_repeater1710] => 1710
            [servername_repeater1710] => 
            [sort_repeater1711] => 3
            [publish_repeater1711] => 0
            [_disable_repeater1711] => 1711
            [servername_repeater1711] => 
            [sort_repeater1712] => 4
            [publish_repeater1712] => 0
            [_disable_repeater1712] => 1712
            [servername_repeater1712] => 
            [_reg_servers_add_items] => 0
            [timezone] => Europe/Berlin
            [submitregistration] => Register Account
            [TOKEN609710988X1412858909] => VehDxck9zIEvN191SQ5G.1HKmG0EeQG41
        )

Now I process $_POST with the function from the linked post.

$servers = getMultiDimensional($_POST, "servername_repeater");

And get back my array

Array
(
    [1798] => A Server
    [1799] => Another Server
    [1800] => And one more Server
    [1801] => 
    [1802] => 
)

Now I can go on from there and process my values.
