<p>I have to make a site for school. It need to be linked with a database. On <code>localhost</code> everything is ok and works, but when I tried to upload it on the host of the school, I get this error: </p> <blockquote> <p>Notice: Undefined index: vragen in /mnt/studentenhomes/arnaud.gandibleux/public_html/datamanagement/index.php on line 44</p> </blockquote> <p>I can't find the solution</p> <p>index.php</p> <pre><code><div id="tekst"> <table align='center'> <?php //if (isset($_GET['vragen'])){ if ($_GET['vragen'] === 'Alleclubs') { getclubs(); } elseif ($_GET['vragen'] === 'ledenvjf') { getVJFleden(); echo "test"; } elseif ($_GET['vragen'] === 'ledenffbj') { getFFBJleden(); } elseif (isset($_GET['clubnr'])) { getLedenPerClubEnID($_GET['clubnr']); } else{ getclubs(); } // } ?> </table> </code></pre> <p>Crud.php</p> <pre><code> function getVJFleden() { global $mysqli; $result = $mysqli->query("SELECT * FROM Leden l JOIN Clubs c ON l.clubnr = c.clubnr join Bonden b ON b.ID_bond = c.ID_bond LEFT JOIN adressen a ON a.ID_adress = l.ID_adress WHERE b.naam_bond = 'VJF';"); if ($result) { if ($result->num_rows > 0) { echo"<caption>Alle leden VJF</caption>"; echo "<th>Voornaam</th><th>achternaam</th><th>leeftijd</th><th>Kye</th><th>adress</th>"; while ($leden = $result->fetch_object()) { echo "<tr><td>$leden->lid_voornaam</td> "; echo "<td>" . $leden->lid_achternaam .

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
