PHP and Mysql with INNER JOIN query - only seeing headers, no data - php

Question

<?php
$conn = mysqli_connect("localhost", "root", "", "konkal");
$result = mysqli_query($conn,"
SELECT *
FROM tb_hitung
JOIN tb_makanan
ON tb_hitung.id = tb_makanan.id
WHERE ket_waktu = 'pagi'
");
while( $row = mysqli_fetch_assoc($result));
?>
<tr>
<th>Gambar Makanan</th>
<th>Nama Makanan</th>
<th>Jenis Makanan</th>
<th>Waktu Makan</th>
<th>Jumlah Kalori</th>
</tr>
<tr>
<td><img src="<?php echo $row['gambar'] ?>" width="100"></td>
<td><?php echo $row["nama"] ?></td>
<td><?php echo $row["kategori"] ?></td>
<td><?php echo $row["ket_waktu"] ?></td>
<td><?php echo $row["kkal"]," kkal" ?></td>
</tr>
Table tb_hitung:
id kkal ket_waktu
12 360 kkal pagi
2 810 kkal malam
24 108 kkal siang
9 286 kkal pagi
Table tb_makanan:
id name kategori keterangan gambar
2 Ampela Lauk 270 Amepela.jpg
3 Usus Lauk 473 Usus
4 Bebek Lauk 300 Bebek
I expect the output to display results where the query filters ket_waktu = 'pagi'. I am only seeing the first row of table (the headers).

Answer 1

PART 1
Join point tb_hitung.id = tb_makanan.id only creates one "match".
For example: tb_hitung id 12 should match to tb_makanan id 12. but tb_makanan has ZERO ROWS with id 12 (no match).
There is a single match...it is on hitung 2 and makanan 2...but the where clause filters to hitung of "pagi". So given this data, the query will have ZERO ROWS.
PART 2
As #barmar mentions...the semicolon ends your while loop without ever looping and the header row should not be within what appears to be your loop. I'll clarify all this chit-chat with one example of an appropriate loop for this purpose:
<?php
$conn = mysqli_connect("localhost", "*******", "", "*******");
// keep your query in a variable for quick debugging
$query = "SELECT * FROM tb_hitung JOIN tb_makanan ON tb_hitung.id = tb_makanan.id";
// i removed the WHERE clause since it was filtering all rows
$result = mysqli_query($conn, $query);
// print your header row OUTSIDE the loop
?>
<tr><th>Gambar</th><th>Nama</th><th>Jenis</th><th>Waktu</th><th>Jumlah</th></tr>
<?php
// now do the loop of the data...
// WHILE should open with an OPENING BRACKET (not end with a semicolon)
while ($row = mysqli_fetch_assoc($result)) {
?>
<tr>
<td><img src="<?php echo $row['gambar'] ?>" width="100"></td>
<td><?php echo $row["nama"] ?></td>
<td><?php echo $row["kategori"] ?></td>
<td><?php echo $row["ket_waktu"] ?></td>
<td><?php echo $row["kkal"]," kkal" ?></td>
</tr>
<?php
// now we must END THE WHILE LOOP
}
