Question

我是PHP学习者。我有一个基于PHP的网站。在我们的一个网站页面的前端有四个选项卡。请参阅下面的图片以供参考 -

我想在此处再添加一个标签。应该有一个简单的选项，可以在此选项卡的管理面板中添加内容（我已完成）

我的问题是，当我在管理面板中向文本区域添加内容并点击提交时，内容会消失。我猜这些内容没有存储在数据库中。我检查了SQL文件所做的可能的更改。虽然我不确定我是否做得对。但我很确定这里有一个非常小的滞后，我无法弄明白。

P.S。查看管理面板的屏幕截图，了解有关我的问题的更多说明。

带标题目录 - 简单的文本区域是我添加的文本区域。但正如我所提到的，即使在这里添加内容并点击提交，它也会变成空白。

以下是截图中页面的代码 -

"<?php
require_once '../config/config.php';
require_once '../class/dbclass.php';
require_once 'class/content.php';
require_once 'class/category.php';
require_once 'class/common.php';

$content = new Content();

$category = new Category();enter code here
$catList = $category->fetchCategoryTree();
//echo '<pre>';
//print_r($catList);
//echo '</pre>';
//exit;

//$catParentList = $category->fetchParentCategory(30);

//echo '<pre>';
//print_r($catParentList);
//echo '</pre>';

//echo implode("->",$catParentList);
//echo '<pre>';
//print_r(array_reverse($catParentList));
//echo '</pre>';

//exit;

$cat_id = 0;
$title = '';
$price = '';
$description = '';
$descriptions = '';
$author = $published = $report_code = '';

$content_id = isset($_REQUEST['id']) && $_REQUEST['id'] != "" ? $_REQUEST['id'] : 0;
//$category_list = $category->getAllCategory();
if ($content_id) {
    $contentData = $content->getContentById($content_id);
    $cat_id = isset($contentData[0]['cat_id']) ? $contentData[0]['cat_id'] : '';
    $title = isset($contentData[0]['title']) ? $contentData[0]['title'] : '';
    $price = isset($contentData[0]['price']) ? $contentData[0]['price'] : '';

}
