在页面重新加载时传递$ _GET参数 [英] Passing $_GET parameters on page reload

问题描述

我试图做到这一点，以便在页面重新加载时使用与上一页相同的$ _GET参数重定向我.现在，我正在尝试使用标头来实现此目的，但是当我提交表单时，变量$ id为空.

I am trying to make it so when the page reloads it redirects me with the same $_GET parameters as the previous page. Right now I am trying to use header to achieve this, but when I submit my form the variable $id is blank.

HTML表单

<form action = "." method ="post">
<input type = "text" name = "username">
<textarea name = "comments"></textarea>
<input type = "hidden" name = "action" value = "posts"> 
<input type = "submit" name = "submit" value = "Add Post">
</form>

重定向脚本

if ( empty( $_GET ) && !empty($_POST) ){
if($action == 'posts'){
if(!isset($_GET['thread'])){
$id = $_GET['thread'];
header('Location: ' . $_SERVER['REQUEST_URI'] .'?thread='.$id);
}   
}

感谢任何回复！

推荐答案

您的重定向脚本没有多大意义.试试吧，也许

Your redirect script doesn't make a lot of sense. Try this, maybe

if ( empty( $_GET ) && !empty($_POST) ){
    if(isset($_POST['thread'])){
        $id = $_POST['thread'];
        header('Location: ' . $_SERVER['REQUEST_URI'] .'?thread='.$id);
    }   
}
