How to fix comment section in PHP and MySQL? - php

Question

The problem is I think in function viewNews(), so I made that function to get the articles/news from database. Well, I tried to put function showCommentsArea() inside viewNews() function, but it shows me same comments in every article, I want like separated comments for every article, like on Facebook, I mean, when you enter someone's post (in this case article), you can publish a comment only for that post (article).
I tried putting showCommentsArea() function inside viewNews() function, right after displaying timestamp of that article.
# Function for viewing news. #
function viewNews()
{
global $db;
$query = "SELECT * FROM newsmodule ORDER BY timestamp";
$result = #mysqli_query($db, $query);
if (!$result)
{
echo "Error selecting headline from database.";
exit();
}
if (mysqli_num_rows($result) > 0)
{
echo "<div style='margin-left: 0; width: 100%;' class='jumbotron'>";
while ($row = mysqli_fetch_object($result))
{
echo "<h1><br>" . $row->headline . "</h1>";
echo "<hr>";
echo "<p>" . $row->storyline . "</p>";
echo "<hr>";
echo "<h5 class='pull-right'>" . $row->username . "</h5>";
echo "<p>" . $row->timestamp . "</p>";
echo "<hr>";
echo showCommentArea();
echo "<a data-target='#postComment' class='text-white dropdown-toggle btn btn-danger' data-toggle='modal' type='button'>";
echo "Publish a Comment";
echo "</a>";
}
echo "</div>";
}
else
{
echo "No headlines in database.";
}
}
function showCommentArea()
{
global $db, $errors, $username;
if(count($errors) == 0)
{
$query = "SELECT comment, name FROM comments
JOIN newsmodule ON comments.articlecID=newsmodule.id WHERE newsmodule.id=comments.articlecID";
$result = #mysqli_query($db, $query);
if(!$result)
{
echo "SQL Query ERROR: !ERR_SQL_QUERY_01";
exit();
}
if (mysqli_num_rows($result) > 0) {
echo "<div>";
echo "<h4>";
echo "Comments:";
echo "</h4>";
echo "<br>";
while ($row = mysqli_fetch_object($result)) {
echo "<p class='text-danger' style='font-weight: bold;'>" . $row->name . "</p>";
echo "<p>" . $row->comment . "</p>";
}
echo "</div>";
}
}
}
So, I expect to have one individual comments section for one individual post, you see I tried to add it with JOINING tables, but it shows me entire table 'comments'
