Good evening,

perhaps one or two of you can help me here.

I am currently building a page for advertising holiday homes. A holiday home landlord should be able to create a house. To do this, he should be able to enter key data (street, location), features, leisure activities, keywords and images in various PHP files. On the last page, he should then receive a summary of all the houses entered. Each white card should show a single house with its attributes.

The code for this page is as follows:

PHP-Code:


<?php //Establishing the connection require("connection.php"); //Starting the season session_start(); //Embedding css file echo '<link rel="stylesheet" type="text/css" href="styleneu.css">';

The problem is the for each loop for the keywords (and then also the images). I've attached the screenshots of the keyword tables. Multiple keywords can be entered for each house entered using one input.
The output then does not produce the associated keywords for each house in a nicely compressed form according to the house ID, but as individual outputs.

How could I solve this so that the keyword list is only output once for each house entered (i.e. each individual house ID)?

Please do not debate the usefulness of the code. I am only concerned that for each house orfor each house_ID the corresponding keywords are output as a list...

Step 1: Adjust the SQL query

Make sure that your SQL query groups the data correctly and only retrieves the required fields. In your case it would make sense to collect the keywords in a GROUP_CONCAT function if your database is MySQL or MariaDB:
SELECT h.*, GROUP_CONCAT(k.keyword SEPARATOR ', ') AS keyword_list
FROM haeuser AS h
JOIN ausstattungsmerkmale AS a ON h.Haus_ID = a.Haus_ID
JOIN freizeitmoeglichkeiten AS f ON h.Haus_ID = f.Haus_ID
JOIN keywords AS k ON h.Haus_ID = k.Haus_ID
WHERE h.eigentuemer_ID = :eigentuemer_ID
GROUP BY h.Haus_ID;
Make sure that the data is processed and output correctly:
<?php
// Establish connection to the database
require("connection.php");

// Start session
session_start();

// Include CSS file
echo '<link rel="stylesheet" type="text/css" href="styleneu.css">';

// Owner ID from the session
$Merker = $_SESSION["eigentuemer_ID"];

// Prepare SQL query
$stmt = $con->prepare(
"SELECT h.*, GROUP_CONCAT(k.keyword SEPARATOR ', ') AS keyword_list
FROM houses AS h
JOIN equipment features AS a ON h.House_ID = a.House_ID
JOIN leisure options AS f ON h.House_ID = f.House_ID
JOIN keywords AS k ON h.House_ID = k.House_ID
WHERE h.owner_ID =

wner_ID
GROUP BY h.House_ID"
);

$stmt->bindParam('

wner_ID', $Marker, PDO::PARAM_INT);
$stmt->execute();
$Results list = $stmt->fetchAll();
?>
