I have this database
TABLE "ADS"
ID | Visible
-----------------
15 | 1
16 | 1
17 | 1
TABLE "IMAGES_ADS"
ID | NAME | ID_ADS
------------------------------
100 | xlasd.jpg | 15
101 | dadsa.jpg | 15
102 | dsfsf.jpg | 16
103 | ghdfd.jpg | 17
104 | jkyhg.jpg | 17
105 | rerem.jpg | 17
Now I want create a php page that get values from this 2 tables and print a list of ADS by id with a row of the images name relate to the ADS ID separated by a comma.
I wrote this code
<?php
//ENTER YOUR DATABASE CONNECTION INFO BELOW:
$servername = "localhost";
$username = "user";
$password = "xxxxxx";
$dbname = "dbname";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
} else {
echo 'CONNECT TO DB';
}
$sql = "SELECT ADS.ID, IMAGES_ADS.NAME FROM ADS INNER JOIN IMAGES_ADS ON ADS.ID=IMAGES_ADS.ID_ADS WHERE ADS.Visible=1 ORDER BY ID ASC";
$results = $conn->query($sql);
echo '<table>';
if($results->num_rows > 0) {
while($row = $results->fetch_assoc()) {
echo '<tr>
<td>'.$row["ID"].'</td>
<td>'.$row["NAME"].'</td>
</tr>';
}
} else {
echo '0 rows';
}
echo '</table>';
$conn->close();
?>
But with this code I get this result:
15 xlasd.jpg
15 dadsa.jpg
16 dsfsf.jpg
17 ghdfd.jpg
17 jkyhg.jpg
17 rerem.jpg
But I need this kind of result:
15 xlasd.jpg, dadsa.jpg
16 dsfsf.jpg
17 ghdfd.jpg, jkyhg.jpg, rerem.jpg
How can I have this result?
Thanks to @Vipin Jain I write the solution below:
<?php
//ENTER YOUR DATABASE CONNECTION INFO BELOW:
$servername = "localhost";
$username = "user";
$password = "xxxxxx";
$dbname = "dbname";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
} else {
echo 'CONNECT TO DB';
}
$sql = "SELECT ADS.ID, GROUP_CONCAT(IMAGES_ADS.NAME SEPARATOR', ') as b
FROM ADS INNER JOIN IMAGES_ADS
ON ADS.ID=IMAGES_ADS.ID_ADS
WHERE ADS.Visible=1
ORDER BY ID ASC";
$results = $conn->query($sql);
echo '<table>';
if($results->num_rows > 0) {
while($row = $results->fetch_assoc()) {
echo '<tr>
<td>'.$row["ID"].'</td>
<td>'.$row["b"].'</td>
</tr>';
}
} else {
echo '0 rows';
}
echo '</table>';
$conn->close();
?>
You should use the GROUP_CONCAT
SELECT ADS.ID, GROUP_CONCAT(IMAGES_ADS.NAME)
FROM ADS
INNER JOIN IMAGES_ADS
ON ADS.ID=IMAGES_ADS.ID_ADS
WHERE ADS.Visible=1
GROUP BY ID
ORDER BY ID ASC;
You can get by below query-
SELECT a.ID, GROUP_CONCAT(b.NAME)
FROM ADS as a
INNER JOIN IMAGES_ADS as b
ON a.ID=b.ID_ADS
WHERE ADS.Visible=1
Group by a.ID;
$res = [];
while($row = $results->fetch_assoc()) {
if (empty($res[$row["ID"]])) {
$res[$row["ID"]] = [$row];
} else {
$res[$row["ID"]][] = $row;
}
}
you'll get arrays of rows grouped by ID
