如何通过 Id Joomla 3 获取文章介绍图片

2022-01-06 00:00:00 php joomla

我正在尝试在 Joomla 3.0 中获取文章的介绍图片我找到了这段代码，但它不起作用:

I'm trying to get Article's intro Image in Joomla 3.0 I found this code and it's not working:

$article = JTable::getInstance("content"); 
$article->load(JRequest::getInt("id")); // Get Article ID 
$article_images = $article->get("images"); // Get image parameters
$pictures = json_decode($article_images); // Split the parameters apart
// Print the image
echo "<img src='" . $pictures->{'image_intro'} . "' alt='" . $pictures->{'image_intro_alt'} . "'>";

我得到了 JRequest::getInt 折旧的信息，当我试图获取 $pictures 时，我得到了空值.有人能告诉我如何通过文章 ID 获得 1 张介绍图片吗?

I got info that JRequest::getInt is depreciated and i when i'm trying to get $pictures i got null. Can somebody tell me how to get 1 intro image by article id ?

推荐答案

请试试这个代码:

$article_id = JFactory::getApplication()->input->get('id'); // get article id

$db = JFactory::getDbo();
$query = $db->getQuery(true)
    ->select($db->quoteName('images'))
    ->from($db->quoteName('#__content'))
    ->where('id = '. $db->Quote($article_id));

$db->setQuery($query);
$result = $db->loadResult();
$intro_image = json_decode($result)->image_intro;

echo $intro_image;

祝你好运！
