我有一个表和MySql的结果。第一排和第二排在一起,但第三排没有。
代码:
$db = mysqli_connect($host, $user, $pass,$database);
if($db){
$h.= "";
$h.= "<form><table class='table table-striped table-hover'>";
$h.= "<tr>";
$h.= "<th>Nr.</th>";
$h.= "<th>Albums</th>";
$h.= "<th>Artiest</th>";
$h.= "<th>Nummer</th>";
$h.= "<th></th>";
$h.='<ul class="nav nav-pills" role="tablist">';
$h.=" <li role='presentation' class='active'><a href='http://localhost:8888/?action=album '>Albums<span class='badge'></span></a></li>";
$h.=' <li role="presentation"><a href="http://localhost:8888/?action=songs">Songs</a></li>';
//$h.='<input type="button" class="btn btn-primary style="float: right"><a href="http://localhost:8888/?action=add-album">';
$h.= "<td style='text-align:right;'><a href='/?action=add-album' class='btn btn-primary'>VOEG TOE</a></td>";
$h.='</ul>';
$h.="<br>";
$h.= "</tr>";
$sql = mysqli_query($db,"SELECT * FROM albums");
$sql1 = mysqli_query($db,"SELECT * FROM artiesten");
if($sql){
if(mysqli_num_rows($sql)>0){
while ($row = mysqli_fetch_assoc($sql)){
$h.= "<tr>";
$h.= "<td>".$row['id']."</td>";
$h.= "<td>".$row['albumName']."</td>";
while ($row1 = mysqli_fetch_assoc($sql1)){
$h.= "<td>".$row1['artiest']."</td>";
}
$h.= "<td>";
$h.= "<td style='text-align:right;'><a href='/?action=show-song&id=".$row['id']."'' class='btn btn-primary'>Zie nummers</a> ";
$h.= "<style='text-align:right;'><a href='/?action=delete-album&id=".$row['id']."'' class='btn btn-danger'>VERWIJDER</a></td>";
$h.= "</tr>";
}
}else{
echo "<tr>No Recore Found</tr>";
}
$h.= "</table></form>";
echo $htop;
echo $h;
echo $hbot;
}else{
echo "Query error".mysqli_error($db);
}
}else{
echo "connection error".mysqli_connect_error();
}
最佳答案
您需要在第二个表中创建“albumid”,以便可以用正确的相册打印正确的艺术家。
然后修改代码如下:
$sql = mysqli_query($db,"SELECT * FROM albums"); //get the albums
if($sql) {
if(mysqli_num_rows($sql)>0) { //if you have some albums to print...
while ($row = mysqli_fetch_assoc($sql)) {
//start printing a row
$h.= "<tr>";
$h.= "<td>".$row['id']."</td>";
$h.= "<td>".$row['albumName']."</td>";
//now get the artiest for the album by querying the correct albumid
$albumid = $row['id'];
$sql1 = mysqli_query($db,"SELECT * FROM artiesten where albumid = '$albumid' ");
while ($row1 = mysqli_fetch_assoc($sql1)){
$h.= "<td>".$row1['artiest']."</td>"; //print the right artiest
}
$h.= "<td style='text-align:right;'><a href='/?action=show-song&id=".$row['id']."'' class='btn btn-primary'>Zie nummers</a> ";
$h.= "<style='text-align:right;'><a href='/?action=delete-album&id=".$row['id']."'' class='btn btn-danger'>VERWIJDER</a></td>";
$h.= "</tr>";
}
}else{
echo "<tr>No Recore Found</tr>";
}
