我有这个脚本：

<?php
/**
 * The template for displaying all pages.
 * Template Name: modify.php
 * This is the template that displays all pages by default.
 * Please note that this is the WordPress construct of pages
 * and that other 'pages' on your WordPress site will use a
 * different template.
 *
 * @package WordPress
 * @subpackage Twenty_Twelve
 * @since Twenty Twelve 1.0
 */

get_header(); ?>


    <div id="primary" class="site-content">
        <div id="content" role="main">


            <?php while ( have_posts() ) : the_post(); ?>
                <?php get_template_part( 'content', 'page' ); ?>
                <?php comments_template( '', true ); ?>

            <?php endwhile; // end of the loop. ?>



<?php

$user_id = get_current_user_id();
if($user_id==0)
{
    echo "Login please";
    exit;
}

mysql_connect("localhost", "", "") or die (mysql_error());
#echo "Connected to MYSQL ";
mysql_select_db("derp") or die (mysql_error());
#echo "Connected to Data Base";
/*$query = "SELECT * FROM addserverame WHERE userId='{$user_id}'";
$result = mysql_query ($query) or die (mysql_error());*/

    if(!isset($_POST['submit'])) {
    $q = "SELECT * FROM addserverame WHERE ID = $_GET[id] AND userId='{$user_id}'";
    $result = mysql_query ($q);
    $person = mysql_fetch_array ($result);
    }

    ?>

<?php //endif; ?>

<?php get_footer(); ?>

我无法弄清楚逻辑错误是什么，如果有的话。

会发生什么 他们应该能够编辑它并更新表格。

发生了什么 用户将尝试编辑它，但它不会更新，没有成功的修改回显，它们被重定向到首页。

任何人都可以向我解释为什么会发生这种情况而不是我想要发生的事情。

谢谢

您的表单失败的可能原因是该表单没有在您的默认页面中运行，它路由到您的索引页面中的某个位置，因为它为您提供了正在执行的 php 文件并且 index.php 所以主要原因可能是您的表单操作即你在你的表单中使用动作，比如

action="<?php echo $_SERVER['PHP_SELF']; ?>"

所以它可能会重定向到您的主页，即 index.php 所以将您的表单操作留空可能会对您有所帮助
