Answer 1

What issue do you face here? I've written a sample code like you and it works completely fine by simply using $_POST.

x.php

<form method="post" action="t.php">
    <input type="text" name="__somename" value="asa">
    <input type="submit">
</form>

t.php

var_dump($_POST);
var_dump($_POST["__somename"]);

Output

array (size=1) '__somename' => string 'asa' (length=3)

string 'asa' (length=3)
