在打开标签之前删除空白区域

Answer 2

有一些小问题：

您不需要输出缓冲
您的开关案例不在引号中，因此它们将被解释为常数而不是字符串
在开幕<?php
您的重定向不是相对于文档根目录，所以如果这是在子目录，他们可能不会重定向到您希望的地方

像这样的事情应该解决这些问题：

<?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;
}

正如OP在我的评论中所要求的那样，这是一个改进代码以缩短代码的建议。我的PHP有点生疏，我没有什么可以在这里测试所以希望没有语法错误，无论如何这个想法就在那里：

<?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();
?>

请注意，为了示例，我在这里定义了$URL_array，但在某种配置文件中会更好，通过将配置与逻辑分离来改进代码：如果需要添加新元素，你不应该修改代码。

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.
