Question

我是CI中的菜鸟，我无法在数据库中插入数据，这是我所做的全部，它没有显示错误，但我没有得到结果，

admin.php（控制器）

public function postnews(){

请帮助我，我复制了所有的东西，以保证我不会忽视某些事情，

好的，我们先来清理代码吧。您无需在if ($_SESSION['admin'] == 'loged')方法中创建每个自变量，而是可以使用函数extract();。 extract()方法为提供的数组中的每个键创建一个变量。假设您在数组name中有密钥$_POST，则extract方法将为您创建名为name的变量。要检索该值，您只需访问变量$name。

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

    extract($_POST);

}

其次，如果要在if语句中检查多个内容，则不要使用单词and，而是使用以下操作数'＆amp;＆amp;'。

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']))

不是手动检查是否已在$_POST数组中设置每个对象，而是可以遍历$_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，迭代$_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);

}

推测插入不起作用的实际原因是因为它实际上并未被调用。这背后的原因是某些键实际上没有设置。

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 />";

}
