Question

I am receiving this error when trying to pass a value via hidden input in a form. I have used this multiple times before, and I can’t seem to figure out why it is not passing this time in particular.

Code from the form on index:

<form method="post" action="viewchars.php">
    <input type="hidden" name="uname" value="testuser" />
</form>

Code on viewchars.php:

<?php
    $user = $_POST["uname"];
?>

The error states that uname is the undefined index.

I am not trying to get the error to just go away, as I actually need the value being passed for the viewchars.php page.

Answer 1

add submit button in your html

<form method="post" action="viewchars.php">
    <input type="hidden" name="uname"  value="testuser" />
    <input type="submit" value="Submit"/>
</form>
