使用HTML表单将jQuery对象转换为PHP数组

Question

I have a jQuery object which is appended to form field like, 我有一个jQuery对象，它附加到表单字段中，例如，

var params = {
    'product_id': productId,
    'width': width,
    'drop': drop
};

$("#sample-form input[name='params']").val(params);

Form looks like, 表格看起来像

<form id="sample-form" action="url" method="post">
    <input type="hidden" name="params"/>
    <button type="submit">Submit</button>
</form>

On receiving this "params" using POST data in PHP, I get string with value "[object Object]" 在PHP中使用POST数据接收到此“参数”后，我得到的字符串值为“ [object Object]”

How do I convert this into array? 如何将其转换为数组？

Answer 1

I converted jQuery object into stringified JSON as, 我将jQuery对象转换为字符串化的JSON，

$("#sample-form input[name='params']").val(JSON.stringify(params));

In PHP, convert received JSON into PHP array as, 在PHP中，将收到的JSON转换为PHP数组，

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