    <p>I am making a project for one course and I need to make a prototype of a movie website with all the artists and movies. I need to display the results of the search by the name of the artist and to make a link to a page with more details about the artist. Part of code for search page:</p> <pre><code> elseif ($method=='artist') { $x=0; $query = "SELECT artistId, image, firstname,lastname,dateOfBirth,otherInfo FROM $artists WHERE CONCAT(firstname, ' ', lastname) LIKE '%$kword%' OR lastname LIKE '%$kword%' or firstname like '%$kword%'"; mysqli_select_db($connect, $mydb); $result = mysqli_query($connect, $query); if($result) { print '&lt;table &gt;'; while ($sqlRow=mysqli_fetch_array($result, MYSQL_ASSOC)) { $x++; echo "&lt;tr&gt;"; echo "&lt;td rowspan=\"3\" id=\"image\"&gt;"; echo '&lt;img src="' . $sqlRow['image'] . '" alt="alt"&gt;'; echo"&lt;/td&gt;"; echo "&lt;td id=\"title\"&gt;&lt;strong&gt;&lt;a href=artist_details.php?id=".$sqlRow['artistId']."&gt;".$sqlRow['firstname']." ".$sqlRow['lastname']."&lt;/strong&gt;&lt;/td&gt;"; echo "&lt;/tr&gt;"; echo "&lt;tr&gt;"; echo "&lt;td id=\"date\"&gt;&lt;strong&gt;".$sqlRow['dateOfBirth']."&lt;/strong&gt;&lt;/td&gt;"; echo "&lt;/tr&gt;"; echo "&lt;tr&gt;"; echo "&lt;td id=\"desc\"&gt;".$sqlRow['otherInfo']."&lt;/td&gt;"; echo "&lt;/tr&gt;"; } print '&lt;/table&gt;'; if ($x==0) { echo "&lt;h4&gt;"; echo "No matches found"; echo "&lt;/h4&gt;"; } } } </code></pre> <p>The code for the details page:</p> <pre><code>$query = "SELECT artistId, image, firstname,lastname,dateOfBirth,otherInfo FROM $artists WHERE artistId=".$_GET['artistId']; mysqli_select_db($connect, $mydb); $result = mysqli_query($connect, $query); if($result) { print '&lt;table &gt;'; while ($sqlRow=mysqli_fetch_array($result, MYSQL_ASSOC)) { $x++; echo "&lt;tr&gt;"; echo "&lt;td rowspan=\"3\" id=\"image\"&gt;"; echo '&lt;img src="' . $sqlRow['image'] . '" alt="alt"&gt;'; echo"&lt;/td&gt;"; echo "&lt;td id=\"title\"&gt;&lt;strong&gt;&lt;a href=\"artist_detail.php?id=".$sqlRow['artistId']."\"&gt;".$sqlRow['firstname']." ".$sqlRow['lastname']."&lt;/strong&gt;&lt;/td&gt;"; echo "&lt;/tr&gt;"; echo "&lt;tr&gt;"; echo "&lt;td id=\"date\"&gt;&lt;strong&gt;".$sqlRow['dateOfBirth']."&lt;/strong&gt;&lt;/td&gt;"; echo "&lt;/tr&gt;"; echo "&lt;tr&gt;"; echo "&lt;td id=\"desc\"&gt;".$sqlRow['otherInfo']."&lt;/td&gt;"; echo "&lt;/tr&gt;"; } print '&lt;/table&gt;'; } </code></pre> <p>Every time I get the same error:Undefined index: artistId. I would be really grateful for your help! :)</p>

    1. COAre you passing in `artistId=<something>` in the URL? And are you aware that your code is open to an SQL injection attack?

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
