Deliver PHP array from ajax to HTML field

Question

Well, I’m wearing it $.ajax to recover a json_encode() in an archive PHP.

In that file is populous one form:

$html .= "
        <input type='hidden' id='dados' value='" . $relatoriosGr . "' />
        <button id='btnRelatorio' class='button'>Gerar Relatório</button>
    ";
echo json_encode( $html );

The problem is here:

<input type='hidden' id='dados' value='" . $relatoriosGr . "' />

When at the end of this php file goes through json_encode it gives error because $relatoriosGr is an array PHP.

If I try to play him like that:

echo json_encode( array ($html, $relatoriosGr) );

but when it comes to $.ajax back, I end up having trouble transferring this array encoded to the created field.

success: function (result) {
    $(".resposta").html(result[0]);
    $("#dados").val(JSON.parse(result[1]));
}

How to solve this?

ADD: array $relatoriosGr in the PHP

Array
(
    [17] => Array
        (
            [0] => Array
                (
                    [data] => 2019-03-01
                    [ofetas] => 22.65
                    [decisoes] => 6
                )

            [1] => Array
                (
                    [data] => 2019-03-03
                    [ofetas] => 55.33
                    [decisoes] => 3
                )

            [2] => Array
                (

                    [ofetas] => 30.45
                    [decisoes] => 2
                )

        )

    [18] => Array
        (
            [0] => Array
                (
                    [data] => 2019-03-02
                    [ofetas] => 78.39
                    [decisoes] => 0
                )

            [1] => Array
                (
                    [data] => 2019-03-05
                    [ofetas] => 30.00
                    [decisoes] => 1
                )

        )

Look, I think the best way for you to repurpose the input information would be like this:

php

$html .= "
        <input type='hidden' name='dados' id='dados' value='" . json_encode($relatoriosGr). "' />
        <button id='btnRelatorio' class='button'>Gerar Relatório</button>
    ";
echo $html;

javascript

success: function (result) {
    $(".resposta").html(result);
}

---

When the form is posted, just retrieve the information like this, in php or javascript:

php

$array = json_decode($_POST['dados'], true);

javascript

var str = $("#dados").val(); // pega a string em json
var obj = JSON.parse(str); // transforma em objeto (tipo de vetor)

In javascript you can send the string to php via ajax and transform into array with json_decode.
