Question

textarea不会读取输入框中输入的任何内容。最初，我使用PHP检查textarea是否为空，并在那里收到错误。所以我删除了那个检查，看看它是否是导致问题的php，并将required="required"属性添加到textarea标签，甚至那回来了Please fill out this field.我不太确定我的代码出错了，我以前工作过，然后突然间它停止工作了，我完全不知道为什么。我还看了关于textarea没有提交的其他各种帖子，并确保我用姓名而不是ID来检查帖子;并确保textarea提交与提交按钮相同的表单。我也试过了，没有在textarea标签上指定表格。

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

Answer 1

您的网页正在使用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. 修复将解决您的问题。

Answer 2

TinyMCE不会始终保持基础textarea同步。通常，当您发布表单时，TinyMCE将在发布表单之前更新textarea，但该过程似乎已被所需属性停止。您可以使用以下API调用强制TinyMCE更新textarea：

tinymce.triggerSave();

这将迫使TinyMCE在被调用时更新textarea。你可以：

在表格

在TinyMCE init中执行此操作：

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

Answer 3

嗯，您是否尝试从Textarea中删除此“表单”属性？

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

告诉我们你在尝试时做了什么。

Answer 4

您可能无法发布任何内容，因为您不指定了表单的action属性。

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

将其设置为php文件的名称（具有文件的正确路径），它应该工作。

注意：要确保$_POST数组包含表单提交的值，请执行var_dump($_POST)。

Answer 5

更改此

try
{   
    string VNumber = null;      //outside the loop
    while (DR.Read())
    {
        #region Fetching DB data
        DateTime TimeStamp = (DateTime)DR["ExceptionDate"];
        VNumber = (string)DR["VisitNumber"];
        Console.Write("Total Visits = " +VNumber "\n");
        #endregion
        DR.Close();
    }

    cmd = new SqlCommand("UPDATE People SET Visits = '0' WHERE VisitNumber = '" + VNumber + "'", connection);   //The name 'VNumber' does not exist in the current context
    cmd.ExecuteNonQuery();
}

到这个

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

Textarea没有阅读任何输入
