Per creare un JSON corretto, prova :`
$result="select title from room_db where hotel='1' order by id asc";
$messages = array();
while($message_data = mysql_fetch_assoc($result)) {
$message = array(
'id' => $message_data['userid'],
'title' => $message_data['title']
);
$messages[] = $message;
}
echo json_encode($messages);
}
`
e sul lato resever fai questo :
`
data1=$.parseJSON(data);
if(data1.length===0){
$('#table > #table_body').append('<tr><td colspan="4" align="center" style="color:red">NO matching data </td></tr>');
}
else{
for(var i=0;i<data1.length;i++)
{
$('#table > #table_body').append('<tr id="' + data1[i]['id'] +'"> <td id="' + data1[i]['id'] +'" align="center" <td>'+data1[i]['title']+'</td> </tr>');
}
}
$('#table').append('</tbody>');
