Question

我尝试使用id这样的交换机案例顺序更新表格

的index.php

<?php $action = (!empty($_REQUEST['action'])) ? $_REQUEST['action'] : "index";
$user = new User();
switch ($action) {
    case "editenewsaction":
        $main_content = "/main_content/Dashboard/edit_new_news";
        require(DIR_VIEWS . 'layouts' . DS . "default.php");
        if (isset($_POST)) {
            $user_id = $_GET['news_id'];
            $user->uid = $user_id;
            $title = trim($_POST['title']);
            $content = trim($_POST['content']);
            $link = $_POST['link'];
            $user->title = $title;
            $user->content = $content;
            $user->link = $link;
            $user->editnews();
            $main_content = "/main_content/Dashboard/mainIndex";
            require(DIR_VIEWS . 'layouts' . DS . "default.php");
        } else {
            $main_content = "main_content/errors/edit_error_msg";
            require(DIR_VIEWS . 'layouts' . DS . "default.php");
        }
        break;
}
?>

user.php的

require(DIR_MODELS . 'database.php');
$database = new MySQLDatabase();

class User {

    protected static $table_data = "data";
    public $uid;
    public $title;
    public $content;
    public $link;

    public function editnews() {
        global $database;
        $newsid = $this->uid;
        $utitle = $this->title;
        $ucontent = $this->content;
        $ulink = $this->link;
        $sql = $database->connect->prepare("UPDATE " . self::$table_data . " SET title = :title, text = :text,links=:links WHERE id = :id");
        $sql->bindParam(':title', $utitle);
        $sql->bindParam(':links', $ucontent);
        $sql->bindParam(':text', $ulink);
        $sql->bindParam(':id', $newsid);
        $sql->execute();
    }

    public static function showTable() {
        global $database;
        $sql = "SELECT * FROM " . self::$table_data . " ";
        $stmt = $database->connect->prepare($sql);
        $stmt->execute();
        $result = $stmt->fetchAll();
        echo"<table border=1>";
        foreach ($result as $row) {
            echo "<tr>";
            echo "<td><a href=index.php?action=newsview&news_id=" . $row['id'] . ">" . $row['title'] . " </a></td>";
            echo "<td><a href=index.php?action=newsview&news_id=" . $row['id'] . "><img src='{$row['links']}' /> </a></td>";
            echo "<td><a href=index.php?action=editenewsaction&news_id=" . $row['id'] . "><pre>edit</pre></a></td>";
            echo "<td><a href=index.php?action=newsview&news_id=" . $row['id'] . "><pre>delete</pre></a></td>";
        }
        echo "</tr>";
        echo "</table>";
    }
}

editnews()方法中的问题是它不起作用。 ShowTable()运行良好，并且create方法在更新中也运行良好，但对我来说不起作用。我希望我没有犯太多错误。

在您的SQL查询中：

UPDATE ... SET title = :title, text = :text,links=:links WHERE id = :id

TEXT是mysql reserved keyword，使用后退标记来逃避它。

UPDATE ... SET title = :title, `text` = :text,links=:links WHERE id = :id

在mysql服务器中，它用于定义用于保存大量文本的数据类型。

使用OOP和switch case在pdo中进行PHP更新
