Hi, i have a problem with the view render, it always render a blank line at the top of the html file, how can i remove that?
in my source code i tried with the view renderer or the view function all of them show the same result
My code in controller
PHP Code: $postData = model(PostModel::class) ->join('post_content', 'post_content.post_id = post.id', 'LEFT') ->where('lang_id', $this->_data['curLang']->id) ->where('post_status', 'publish') ->where('post_type', PostTypeEnum::POST) ->orderBy('post.id', 'desc') ->select('post.id, post.user_init, post.post_type, post.created_at, post_content.title, post_content.slug, post_content.description') ->findAll(500);
// add posts to the feed foreach ($postData as $post) { //dd($post->author); $this->feeds->add($post->title, $post->url, $post->created_at, $post->author, $post->slug, $post->description, $post->categories); }
$renderer = single_service('renderer');
return $renderer ->setData($this->feeds->getData()) ->render('rss');
PHP Code: $postData = model(PostModel::class) ->join('post_content', 'post_content.post_id = post.id', 'LEFT') ->where('lang_id', $this->_data['curLang']->id) ->where('post_status', 'publish') ->where('post_type', PostTypeEnum::POST) ->orderBy('post.id', 'desc') ->select('post.id, post.user_init, post.post_type, post.created_at, post_content.title, post_content.slug, post_content.description') ->findAll(500);
// add posts to the feed foreach ($postData as $post) { //dd($post->author); $this->feeds->add($post->title, $post->url, $post->created_at, $post->author, $post->slug, $post->description, $post->categories); }
return view('rss', $this->feeds->getData(), ['debug' => false]);
My code in view file

Replace echo:
PHP Code: echo '<?xml version="1.0" encoding="'. $channel['encoding'] .'" ?>';
PHP Code: <?php header(); ?><?xml version="1.0" encoding="<?= $channel['encoding'] ?>"

Thanks you all for you help, i solved the problem, I tried you guys solution but it isn't worked!
i shared my solution here in case that someone may face the same problem
First in the controller i replace the extend
From:
Code: class Rss extends BaseController
To:
PHP Code: use CodeIgniter\Controller;
class Rss extends Controller
Second i remove the header function in the view file
Finally fix the index function in the controller use CI response->setheader + setBody for this
PHP Code: public function index() { $postData = model(PostModel::class) ->join('post_content', 'post_content.post_id = post.id', 'LEFT') ->where('lang_id', $this->lang->id) ->where('post_status', 'publish') ->where('post_type', PostTypeEnum::POST) ->orderBy('post.id', 'desc') ->select('post.id, post.user_init, post.post_type, post.created_at, post_content.title, post_content.slug, post_content.description') ->findAll(500);
// add posts to the feed foreach ($postData as $post) { //dd($post->author); $this->feeds->add($post->title, $post->url, $post->created_at, $post->author, $post->slug, $post->description, $post->categories); }
$this->response->setHeader('Content-Type', 'application/xml;charset=UTF-8'); $html = view('rss', $this->feeds->getData(), ['debug' => false]); return $this->response->setBody($html); }
