How to echo specific elements from a database - php

Question

I'm trying to echo certain elements from my news table throughout an article. This involves fields such as the author, headline, content and date. At the moment I can only echo the row and any attempt to echo elements in the page itself is either met with small errors or it outputs nothing. I've had a look around and only found people having problems with simply printing out the row database which I can already do.
Basically when I have Author in my article I want to echo author from my database and it will show next to Author. I'm not sure how possible it is as I am yet to find anything on this or I'm overlooking it.
Here is my current PHP file and I've left in the initial part with the article author, date and headline.
<?php
/* Database connection settings */
$host = 'xxxxx';
$user = 'xxxxx';
$pass = 'xxxxx';
$db = 'xxxxx';
$dbconnect=mysqli_connect($host,$user,$pass,$db);
if ($dbconnect->connect_error) {
die("Database connection failed: " . $dbconnect->connect_error);
}
$query = mysqli_query($dbconnect, "SELECT * FROM news WHERE news_Id = 1")
or die (mysqli_errr($dbconnect));
while ($row = mysqli_fetch_array($query)) {
echo
"<tr>
<td>{$row['headline']}</td>
<td>{$row['content']}</td>
<td>{$row['author']}</td>
<td>{$row['date']}</td>
</tr>\n";
}
?>
<div class="container-fluid bg">
<div class="row">
<div class="col-md-1"></div>
<div class="col-md-10">
<div class="container">
<div class="row mb-2">
<div class="col-md-12">
<div class="card">
<div class="card-body">
<div class="row">
<div class="col-md-12">
<div class="news-title">
<h2><?php echo $row['headline']; ?></h2>
</div>
<div class="news-cats">
<ul class="list-unstyled list-inline mb-1">
<li class="list-inline-item">
<i class="fa fa-folder-o text-danger"></i>
<small>Author:</small>
</li>
<li class="list-inline-item">
<i class="fa fa-folder-o text-danger"></i>
<small>Posted:</small>
</li>
</ul>
</div>

Answer 1

Since your query only returns one row, a while loop is inappropriate for fetching the data, as at the end of the loop, $row will be left as a false value, thus making any attempt to access e.g. $row['headline'] fail. Change your while loop
while ($row = mysqli_fetch_array($query)) {
to a simple assignment:
$row = mysqli_fetch_array($query) or die(mysqli_error($dbconnect));
Note you have a typo earlier in your code,
or die (mysqli_errr($dbconnect));
should be
or die (mysqli_error($dbconnect));

Answer 2

You are just printing out the result, but don't have a label. You can add one like this:
while ($row = mysqli_fetch_array($query)) {
echo
"<tr>
<td>Headline: {$row['headline']}</td>
<td>Content: {$row['content']}</td>
<td>Author: {$row['author']}</td>
<td>Date: {$row['date']}</td>
</tr>\n";
}
