文本区域不读取任何输入

Question

文本区域不读取输入框中的任何内容。最初，我使用 PHP 检查文本区域是否为空，并在那里收到错误。所以我删除了那个检查，看看是否是 php 导致了这个问题，并将 required="required" 属性添加到 textarea 标签，甚至 Please fill out this field. 也回来了我是不太确定我的代码哪里出错了，我以前让它工作，然后突然停止工作，我完全不明白为什么。我还查看了其他各种关于文本区域未提交的 post，并确保我检查的是 post 中的名称，而不是 ID；并确保文本区域提交到与提交按钮相同的表单。我也试过了，没有在 textarea 标签上指定表单。

HTML代码：

    <form action="" method="post" id="CreateTopicForm">
        <input type="hidden" name="create-topic" />
        <span class="secondary radius label"><strong>Title</strong></span>
        <input type="text" name="title" id="title" />

        <span class="secondary radius label"><strong>Message</strong></span>
        <textarea name="content" id="content" required="required" form="CreateTopicForm"></textarea>

        <?php if($_SESSION['user']['account_type'] >= 3): ?>
            <span class="secondary radius label"><strong>Sticky Topic</strong></span>
            <input type="checkbox" name="sticky" /><br />
        <?php endif ?>

        <input type="submit" value="Post Topic" class="topic-post" />
    </form>

PHP代码：

/* Retrieve necessary variables */

$fid = $_GET['fid'];

/* Get Forum Information */
$query = "SELECT * FROM bkg_forums where forum_id = :id";
$query_params = array(
':id' => $fid

try {

$result = $stmt->execute($query_params);

$forum = $stmt->fetchAll();

        $error[] = "Sorry! You must enter a title!";
    }

我看过的问题：

Cannot Get the Value of a Textarea via Post Method

Textarea Not Posting with Form

Answer 1

嗯，您是否尝试从您的 Textarea 中删除此 "form" 属性？

<textarea name="content" id="content" required></textarea>

告诉我们当你尝试时它做了什么。

Answer 2

您可能无法post任何操作，因为您未指定表单的action属性。

<form action="" method="post" id="CreateTopicForm">

将其设置为 php 文件的名称（使用正确的文件路径），它应该可以工作。

注意： 要确保 $_POST 数组包含您提交的表单值，请执行 var_dump($_POST).

Answer 3

改变这个

 <textarea name="content" id="content" required="required" form="CreateTopicForm"></textarea>

至此

  <textarea name="content" id="content" required="required" ></textarea>

Answer 4

您的页面正在使用 TinyMCE 编辑器。它在控制台中出现以下错误：An invalid form control with name='content' is not focusable. 解决这个问题将解决您的问题。

Answer 5

TinyMCE 不会始终保持底层 textarea 同步。通常，当您 post 表单时，TinyMCE 会在表单被 posted 之前更新 textarea，但该过程似乎被 required 属性停止了。您可以使用以下 API 调用来强制 TinyMCE 更新文本区域：

tinymce.triggerSave();

这将强制 TinyMCE 在调用时更新 textarea。您可以：

在表单的 onsubmit 事件中执行此操作

在 TinyMCE 初始化中执行此操作：

tinymce.init({
    selector: "textarea",
    setup: function (editor) {
        editor.on('change', function () {
            tinymce.triggerSave();
        });
    }
});
