Php “如果”发言和会议

我有一个表单正在将会话发回我的索引页。基于这些会话，我使用echo从结果中加载一个模式窗口。我一直有500个错误。我不明白为什么

if($_SESSION["submitemail"] == "fail"){

    echo
        "<script type='text/javascript'>
            $(window).load(function(){
                $('#betaalert').modal('show');
            });
        </script>


        <div class='modal fade' role='dialog' id='formerror'>
          <div class='modal-dialog'>

                echo $_SESSION['errormessage'].'<br /><br />';
                echo '<p>Please go back and fix these errors.</p><br /><br />';

没关系，我知道了！谢谢你，以后我一定会发布更多信息。

我想500个错误在浏览器端-服务器端是什么？也许你应该打开错误报告，看看到底是什么问题，然后把它贴在这里？这不是完整的php文件。至少你会发布完整的php页面来找出哪里出了问题。。
