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);
}
?>

我想不出逻辑错误是什么，如果有的话。
意味着什么 用户选择更新表格，如果表格是他们的，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，他们将被重定向到首页。
有谁能给我解释一下为什么会发生这种情况，而不是我想要发生的情况。
谢谢

最佳答案
您的表单失败的可能原因是该表单未在您的默认页面中运行，该默认页面路由到索引页面中的某个位置，因为它为您提供了正在执行的 php 文件和 index.php，所以主要原因可能是您的表单操作，即您在表单中使用操作，例如
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对您有帮助
关于php - 你能看到逻辑错误吗，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/15941788/
