PHP 多次重定向 [英] PHP multiple redirects

问题描述

我有一个带有单个变量listing_type"的 $_POST 数组.表单提交到包含以下代码的页面，该页面将它们重定向到另一个页面，其中包含更多依赖于初始选择的表单.有没有更巧妙的方法来做到这一点?它工作正常，但感觉很笨重...

I have a $_POST array with a single variable 'listing_type'. The form submits to a page containing the code below which redirects them to another page with more forms dependent on their initial choice. Is there a slicker way to do this? It works fine but feels clunky...

<?php // listing-type.php
if ((isset($_POST['listing_type'])) && (!empty($_POST['listing_type']))) {

    switch($_POST['listing_type']) {
        case "1":
            $url = "events/new-event.php";
            break;
        case "2":
            $url = "restaurants/new-restaurant.php";
            break;
        case "3":
            $url = "bars/new-bar.php";
            break;
        case "4":
            $url = "attractions/new-attraction.php";
            break;  
    }
header("Location: $url"); // Perform redirect to given new listing page
}
else {  // Redirect to homepage if no usuable listing_type data from form
    $url = "index.php";
    header("Location: $url");
}

推荐答案

很好，除了不需要两次定位调用，也不需要 else :

It's fine except there is no need to have two location calls, and you don't need the else:

$url = "index.php";
if ((isset($_POST['listing_type'])) && (!empty($_POST['listing_type']))) {
    // Switch statement
}

header("Location: $url");
