Getting the value of readonly input in nested forms

Question

My code looks somewhat like this:

<form method="POST">
//something
<form method='GET'>
<input readonly type='text' id='userpwd' value= 'Day'  name='count'/>
<input type='submit' id='btn' formaction='admi.php'  name='admin' value='Add Details'></form>
<input type="submit" id="btn" formaction="choose.php"  name="admin" value="Done"></p>
</form>

I want to get the value of readonly type input in my new php file.How could I achieve this.I tried doing this:

$var=$_GET['count'];

but it is giving following error msg:

Notice: Undefined index: count in C:\xampp\htdocs\tourism\admi.php on line 4

Please somebody help me out..!Kindly give some solution in php only.

`
//something
` why 2 different methods? Also, does `$_POST['count']` give you the right value? — nice_dev, Oct 31 '18 at 13:56
You should not nest forms. Can you provide more of the code? — Bryan Joseph Myers, Oct 31 '18 at 13:57
I think that for readonly type input,only GET method works.Kindly correct me if I'm wrong. — Tarishi Jain, Oct 31 '18 at 13:59
`id`s should be unique, as should the `name` of each field, and probably best that they match. You can always use `type="hidden"` to store values in forms. As others have said, you shouldn't nest forms. — JonJ, Oct 31 '18 at 14:00
@TarishiJain `I think that for readonly type input,only GET method works`. There is no such thing. It works with POST too. — nice_dev, Oct 31 '18 at 14:08

<form> element shouldn't be nested:

4.10.3. The form element
Content model:
Flow content, but with no form element descendants.

HTML 5.2 Recommendation

Can't you do both forms seperate (not nested)?

Edit: If you need a readonly field to be sent in your form, you can add a hidden field with the same value :

<input type="hidden" name="count" value="Day" />
<input type="text" name="count" value="Day" readonly />

Nope,I'm working on some DBMS project and this nested thing will help me in further modules. – Tarishi Jain Oct 31 '18 at 14:01

Ok but it's not just a recommendation, I think the nested `
` will be ignored.

It isn't working.Still giving the same error.! – Tarishi Jain Oct 31 '18 at 14:08
Because your `GET` form is being ignored. You can print both `var_dump($_GET);` and `var_dump($_POST);` to see their state. – Maarti Oct 31 '18 at 14:12

<?php
if(isset($_GET['txtUserPwd'])) { echo "<div>" . $_GET['txtUserPwd'] . "</div>"; }
else { ?>
  <form method="GET">
    <input type="text" id="txtUserPwd" name="txtUserPwd" value="Day" readonly />
    <input type="submit" id="btnAdmi" name="btnAdmi" value="Add Details">
    <input type="button" id="btnChoose" name="btnChoose" value="Done">
  </form>
<?php } ?>

This doesn't address your second button. I would do that with JavaScript or jQuery.
