无法通过Jquery.post发送数组

Question

So,I have an array of input values:

<input type="text" placeholder="write your Question" id="question[]"  value="" />

and I'm sending this inputs through this code:

    $.post("function.php",{Question:$("#question").serialize()},function(data){
        $("#construct").append(data);
        alert('done');
    });

But when I try to use these values in my PHP,I have some errors.

PHP(function.php):

$Question=htmlentities($_POST['Question'],ENT_QUOTES,"UTF-8");
//line 13
$Quiz->InsertQuestion($Q_id,$Question[0]);
//line 14
$Quiz->InsertQuestion($Q_id,$Question[1]);

the error says:

Notice: Uninitialized string offset: 0 in E:\program file\program\xampp\htdocs\QMS\admin\function.php on line 13

Notice: Uninitialized string offset: 1 in E:\progrram file\program\xampp\htdocs\QMS\admin\function.php on line 14

thanks in advance.

As I said, id="question[]" and id="question" are different ids. If you want to send items as an array you should use name attribute with []:

<input type="text" placeholder="write your Question" name="question[]"  value="" />
<input type="text" placeholder="write your Question" name="question[]"  value="" />

jquery:

// select all fields which names start with "question"
{Question:$("[name^='question']").serialize()} 

or even class:

<input type="text" placeholder="write your Question" value="" class="question" />
<input type="text" placeholder="write your Question" value="" class="question" />

jquery:

{Question:$(".question").serialize()}
