How to get article intro image by article Id?

Question

I'm trying to get Article's intro Image in Joomla 3.3 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'} . "'>";

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

Answer 1

JRequest is deprecated.

It's been replaced by JInput, so your line:

$article->load(JRequest::getInt("id")); // Get Article ID 

would need to change to:

$id = JFactory::getApplication()->input->getInt('id');
$article->load($id); // Get Article 

Answer 2

Not sure accessing the article is the issue, although you should use JInput veruses JRequest, it shouldn't prevent you from getting the data yet. Unless there is a new technique I've missed in my old age, you are not referencing the image properties properly, try this:

echo "<img src='" . $pictures->image_intro . "' alt='" . $pictures->image_intro_alt . "'>";
