我正在嘗試處理表格。如果有錯誤，用戶將被重定向到表單，錯誤將在此處顯示，用戶嘗試提交的任何內容都會在表單的 tinymce 的 textarea 中回顯。這樣，用戶就不必再次重寫所有內容。一切都運行良好，除了用戶被重定向后會話變量不會在 tinymce 編輯器中回顯。會話變量已設置并具有正確的值。如果我在 tinymce 之外回顯會話變量，它會按預期顯示。它只是不會出現在文本區域中。我該如何解決？另外，我知道這很容易受到 xss 的影響。我想讓用戶格式化他們的帖子，所以稍后我將通過 HTML Purifier 運行它。添加新線程.php：<?php session_start(); if($_SERVER['REQUEST_METHOD']==='POST'){ if(isset($_POST['submit'])&&$_POST['submit']==='success'){ if (empty(trim($_POST['thread-title']))) { $_SESSION['forum_titErr'] = "<p class='error text-center'>Error message</p>"; } else { $_SESSION['threadTitle'] = $_POST['thread-title']; } if (empty(trim($_POST['thread-content']))) { $_SESSION['forum_thrContErr'] = "<p class='error text-center'>Error message </p>"; } else { $_SESSION['threadCont'] = $_POST['thread-content']; } if((isset($_SESSION['forum_titErr'])&&!empty($_SESSION['forum_titErr']))|| (isset($_SESSION['forum_thrContErr'])&&!empty($_SESSION['forum_thrContErr']))) { header("Location: newthread.php?submit=error"); } else { //insert into database and redirect to readtopic.php if insert is successful; else redirect to form and show insert is not successful }}else{ header("Location: newthread.php");}}else{ exit('invalid request');}?>表單html：<!DOCTYPE html><html><?php session_start(); ?><head> <!-- title, meta, stylesheet, etc. --> <script type="text/javascript" src="jquery.js"></script> <script src="https://cdn.tiny.cloud/1/no-api-key/tinymce/5/tinymce.min.js" referrerpolicy="origin"></script> <script>tinymce.init({selector:"#threadCont", height: 300, resize: false });</script></head>
將用戶重定向到頁面后如何在輸入和tinymce textarea中回顯會話變量
