我想在foreach循環中顯示每個表格內容的每首歌曲,我該怎麼做。在for循環中顯示錶格

不是最漂亮的解決方案,但希望它可能對你有所幫助:
require_once ("db/dbconn.php");
$sql = "SELECT * FROM artistcd NATURAL JOIN artist ORDER BY artistID, cdID";
$i = 0;
$previousArtistID = "";
while($row = $result->fetch_assoc()){ // loop through your database
if($row['artistID'] != $previousArtistID){ // if the current artist is not the previous
if($i > 0){
echo "</table>"; // if the artist is not the first, close the previous table
echo "<hr>"; // for demo
}
echo "<table>"; // start a table, with headers
echo "<tr>";
echo "<th>Genre</th>";
echo "<th>CD Identification</th>";
echo "<th>Title</th>";
echo "<th>Price</th>";
echo "</tr>";
echo "<tr>";
echo "<th colspan=\"4\">".$row['artistName']." (".$row['artistID'].")</th>"; // display the artistName/artistID
echo "</tr>";
$i++; // increment counter
$previousArtistID = $row['artistID']; // set the previousArtistID to the current artistID
}
// list all songs
echo "<tr>";
echo "<td>".$row['cdGenre']."</td>";
echo "<td>".$row['cdID']."</td>";
echo "<td>".$row['cdTitle']."</td>";
echo "<td>".$row['cdPrice']."</td>";
echo "</tr>";
}
echo "</table>"; // close the table
謝謝!有用! @justbaron –
如果你想顯示所有藝術家的所有歌曲,從查詢 – JustBaron
刪除'GROUP BY artistID'然後使用'ORDER BY artistName,cdTitle'或者'ORDER BY artistsID,cdTitle' – JustBaron
我想分開每個藝術家的3首歌曲,這就是爲什麼我將它們分組的原因。由於ID相同,它會循環表中的所有數據並回顯所有數據。 –
