[英]mysql grouping same value from one column to echo table
I'm struggling to show the outcome I'm looking for. 我正在努力展示我想要的结果。 I need to create a table which can group the rack column which will be the name of the table and the content is from the layout column is the data for the table.
我需要创建一个表,该表可以对机架列进行分组,机架列将是表的名称,内容来自布局列是该表的数据。
$sql = ' SELECT rack, id, GROUP_CONCAT(layout) as grouped_name FROM sorting_items GROUP BY rack ORDER BY rack ASC';
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo '<td>'.$row['rack'].' </td>';
echo '<table style=" border: 1px solid black; width:100%"><tr>';
echo '<td>'.$row['grouped_name'].' </td>';
echo '</tr></table>';
}
} else {
echo "0 results";
}
$conn->close();
My table is this 我的桌子是这个

It looks like what you actually want in your result data loop is something like this, which splits the grouped_name
field on commas and then outputs each value on a separate table row: 看起来您在结果数据循环中实际想要的是这样的东西,它将逗号分隔开
grouped_name
字段,然后在单独的表行上输出每个值:
while($row = $result->fetch_assoc()) {
echo '<table style=" border: 1px solid black; width:100%">';
echo '<tr><th>'.$row['rack'].' </th></tr>';
foreach (explode(',', $row['grouped_name']) as $name) {
echo '<tr><td>'.$name.' </td></tr>';
}
echo '</table>';
}
