“Index.php?网页”功能不正常

“Index.php?网页”功能不正常,php,post,get,isset,Php,Post,Get,Isset,因此,我试图访问我的网站内的某个网页 在我的索引中,我使用isset$\u GET参数访问另一个页面。我的index.php代码如下所示: <!DOCTYPE html> <html> <head> <?php require ("includes/database.php"); ?> <title>Offstreams Admin Panel</title> <link rel="styles

因此,我试图访问我的网站内的某个网页

在我的索引中,我使用isset$\u GET参数访问另一个页面。我的index.php代码如下所示:

<!DOCTYPE html>
<html>
<head>
    <?php require ("includes/database.php"); ?>
    <title>Offstreams Admin Panel</title>
    <link rel="stylesheet" type="text/css" href="styles/admin_body.css" />
    <link rel="stylesheet" type="text/css" href="styles/admin_header.css" />
    <link rel="stylesheet" type="text/css" href="styles/admin_footer.css" />
    <link rel="stylesheet" type="text/css" href="styles/admin_postspace.css" />
</head>
<body>
    <header>
        <!--Header Info Here -->
    </header>
    <div class="wrapper">
        <div class="sidebar">
            <ul>
                <li><a href="index.php?post_new_band">Post New Band</a></li>
            </ul>
        </div>
        <article>
            <?php
                if (isset($_GET['post_new_band'])){
                    require ("includes/post_new_band.php");

                    echo "Page accessed";
                } else {
                    echo "Page not accessible."; 
                }       
            ?>
        </article>
    </div>
</body>
</html>
当index.php?页面不存在时,我的echo页面不可用。但是当它确实存在时,比如index.php?post_new_下面的带代码,则不会发布任何内容。服务器和数据库工作,这是肯定的。MySQL不是问题所在,因为我正在尝试让html正常工作

post_new_band.php的代码:

<!DOCTYPE html>
<html>
<head>
    <!-- Head Info Goes Here -->
</head>
<body>
   <h1>Insert New Band</h1>
       <form action='index.php?post_new_band' method='post'>
           <b>Insert New Band</b><input type='text' name='band_name' />
           <b>Insert Band Origin</b><input type='text' name='band_origin' />
           <input type='submit' name='insert_band' value='Add Band' />
       </form>

   <?php
       if (isset($_POST['post_new_band'])){
           $band_name = $_POST['band_name'];

           if($band_name==''){
               echo "<script>alert ('Please Insert Band Name')</script>";
               echo "<script>window.open('index.php?post_new_band','_self')</script>"
           } else {

               $insert_band_name = "insert into Band  (band_name) values ('$band_name')";

               $run_band_name = mysql_query("$insert_band_name");

               echo "<script>alert ('New Category Added')</script>";
               echo "<script>window.open('index.php?post_new_band','_self')</script>"
           }
       }
   ?>
</body>
</html>

您只能使用一次请求密钥-因此不要在同一请求中使用$\u GET['post\u new\u band']和$\u post['post\u new\u band']。更改其中一个键。

这很愚蠢,但事实证明这是一个涉及分号的语法错误*打在脸上
