I am working on making a comment system for my website. I want it to have a threaded comment system and I am trying to figure out the best way to loop through different level threads. I really dont think having nested foreach loops is the best approach, but I cannot seem to think of any other way. Here is my code with the nested loops (Its sloppy i know, I am still in the development stages):
function display_comments($blog_post_id, $limit = 0) {
global $dbh, $user;
$return = "";
$comments = $this->get_post_comments($blog_post_id);
foreach ($comments as $comment) {
$comment_user = $user->get_userdata($comment['comment_userid']);
$return .= '<div class="media">
<a class="pull-left" href="#">
<img class="media-object" src="holder.js/64x64" alt="">
</a>
<div class="media-body">
<h4 class="media-heading">'.$comment_user['username'].'</h4>
'.$comment['comment_text'];
$replies = $this->get_comment_replies($comment['comment_id']);
foreach ($replies as $reply) {
$comment_user = $user->get_userdata($comment['comment_userid']);
$return .= '<div class="media">
<a class="pull-left" href="#">
<img class="media-object" src="holder.js/64x64" alt="">
</a>
<div class="media-body">
<h4 class="media-heading">'.$comment_user['username'].'</h4>
'.$comment['comment_text'];
if ($this->reply_count($reply['comment_id'])) {
$replies_level_1 = $this->get_comment_replies($reply['comment_id']);
foreach ($replies_level_1 as $reply_level_1) {
$comment_user = $user->get_userdata($comment['comment_userid']);
$return .= '<div class="media">
<a class="pull-left" href="#">
<img class="media-object" src="holder.js/64x64" alt="">
</a>
<div class="media-body">
<h4 class="media-heading">'.$comment_user['username'].'</h4>
'.$reply_level_1['comment_text'];
}
$return .= '</div></div>';
}
}
$return .= '</div></div>';
}
return $return;
}
Let me know if you need anymore info and thanks for your help!
