我是 CI 的菜鸟，我无法在数据库中插入数据，这是我所做的一切，它没有向我显示错误，但我没有得到结果，

admin.php( Controller )

public function postnews(){

        $ip = $_SERVER['REMOTE_ADDR'];
            if ($ip == "my ip address"){

                    }

                if ($_SESSION['admin'] != 'loged'){
                    $this->load->view('admin-login');
                    die(0);

请帮助我，我复制了几乎所有内容以确保我不会忽略某些内容，

最佳答案

好的，让我们从清理代码开始。不必在 if ($_SESSION['admin'] == 'loged') 中创建每个自变量方法，可以使用函数extract(); . extract()方法为提供的数组中的每个键创建一个变量。假设你有 key name在数组中 $_POST ，extract 方法将创建一个名为 name 的变量为你。要检索该值，您需要做的就是访问变量 $name .

if ($_SESSION['admin'] == 'loged'){

    extract($_POST);

}

其次，你不用 and这个词如果你想在一个 if 语句中检查不止一件事情，你可以使用下面的操作数“&&”。 
if (isset($_POST['title']) && isset($_POST['main-poster']) && isset($_POST['type']) && isset($_POST['year']) && isset($_POST['language']) && isset($_POST['platform']) && isset($_POST['publisher']) && isset($_POST['size']) && isset($_POST['graphics']) && isset($_POST['little-info']) && isset($_POST['full-info']) && isset($_POST['posters']) && isset($_POST['screenshots']) && isset($_POST['trailers']) && isset($_POST['gameplays']) && isset($_POST['author']))

而不是手动检查每个对象是否已在 $_POST 中设置数组，你可以遍历 $_POST .

创建需要设置的变量数组: 
$req_fields = array(

    'title', 
    'main-poster', 
    'type', 
    'year', 
    'language', 
    'platform', 
    'publisher', 
    'size', 
    'graphics', 
    'little-info', 
    'full-info', 
    'posters', 
    'screenshots', 
    'trailers', 
    'gameplays', 
    'author'

);

然后为尚未设置的元素创建一个数组: 
$notset = array();

最后，遍历 $_POST检查是否设置了每个值。如果没有，请将其添加到数组中。 
foreach ($req_fields as $key) {

    if (!isset($_POST[$key]) {

        $notset[] = $key;

    }
}

然后检查是否有任何值尚未设置并重定向用户，否则，加载模型并回显帖子: 
if (count($notset) > 0) {

    $this->load->view('postnews');

}
else {

    $this->load->model('Gamesmodel');
    echo $this->Gamesmodel->PostArticle($title, $main_poster, $type, $year, $language, $platform, $publisher, $size, $graphics, $little_info, $full_info, $posters, $screenshots, $trailers, $gameplays, $autor, $date);

}

大概插入不工作背后的实际原因是因为它实际上没有被调用。这背后的原因是某些键实际上并未设置。

遍历 $notset数组以查看是否是这种情况: 
foreach ($notset as $unsetField) {

    echo "Field {$unsetField} is not set. <br />";

}
