Answer 1

remove the white space before openning the tag

Answer 2

There are a few minor issues:

1. You don't need output buffering
2. Your switch cases are not in quotes so they'll be interpreted as constants rather than strings
3. You seem to have some whitespace before the opening <?php
4. Your redirects aren't relative to the document root so if this in a sub-directory they may not redirect where you expect them to

Something like this should resolve those issues:

<?php
session_start();

$textboxdata = !empty($_POST['textboxdata']) ? $_POST['textboxdata'] : '';
switch ($textboxdata) {

    case 'COL':
        header("Location: /new_item_5piececollar.php");
        exit();

    case 'BAB':
        header("Location: /new_item_babybangle.php");
        exit();

    /* ... and so on ... */

    default:
        echo "Enter a number please.";
        break;
}

Answer 3

As OP requested following my remark, here's a suggestion to improve the code to make it shorter. My PHP is a bit rusty and I've nothing to test here so hopefully there's no syntax error, anyway the idea is there :

<?php
    session_start();
    ob_start();
    $textboxdata = $_POST['textboxdata'];
    $URL_array = array('COL' => 'new_item_5piececollar.php', 'BAB' => 'new_item_babybangle.php', 'BRR' => 'new_item_babyring.php');
    if (isset($textboxdata) && array_key_exists($textboxdata, $URL_array))
    { 
        header("Location: ".$URL_array[$textboxdata]);
    }
    else
    {   
        echo "Enter a number please.";
    }
    ob_end_flush();
?>  

Note that for the sake of example I defined $URL_array here but it would be better in some kind of config file, improving the code even more by separating config from logic : if you need to add a new element, you shouldn't modify the code.

Answer 4

Sometimes your output buffers are on if you're on a development server, but in most of the cases it's turned off on live-systems. Check your .INI file for the following parts:

http://php.net/manual/en/outcontrol.configuration.php

Otherwise check out that there is no output before the headers are sent.
