Created Input from javascript not delivering its value

Question

i created an input from javascript like this:

<form action='' method='post' name='create'>
    <span id="duration"></span>
</form>


function duration(){
        document.getElementById('duration').innerHTML += "<label>Deadline  :</label><input type='date' name='deadline' id='deadline' onchange='pengumuman(this.value)' class='form-control' min=" + date('now', 0, 'ymd') + " max=" + date('now', 7, 'ymd') + ">";
        }

And i created a span inside a form, but whenever I tried to submit this form and print I got no value (string(0) = "") or $_GET['deadline']; (and i just tried $_POST['deadline'] also but still the same. not found Undefined index: deadline from this input. How to fix this? Do created input from javascript can't be inputted in form?

I'm not a PHP dev, however, I think you need to use: $_POST['deadline']; — Ele

Can you share your php code? Also, there is no submit button in your form so how you are posting the form? — Aefits

POST parameters come in on $_POST, not $_GET. $_GET is for GET parameters. Since your form has method='post', it will send its data via POST.

The min=" + date('now', 0, 'ymd') + " max=" + date('now', 7, 'ymd') + part of your code also looks suspect, unless you've defined a JavaScript function alled date.

I just tried your suggestion and it still the same, i got Undefined index: deadline. And function on min and max attribute are nothing to do with it cause it works like a charm.
