I'm not even sure about this, and it may sound silly, but maybe try to remove the quotes/backtick off the Modul field name.

Verify the column datatype is really not VARCHAR: DESCRIBE videos; maybe try to sort by directly converting the values to number: ORDER BY CAST(Modul AS UNSIGNED)

found out that the code $db_res= mysqli_query($db_link, "SELECT * FROM `videos` ORDER BY CAST(`Modul` AS INT)"); $array=array(); while($row=mysqli_fetch_array($db_res)){ array_push($array,$row); } and <script> var vidArray= <?php echo json_encode($array); ?>;</script> gives a string back what a previous integer was. In Javascript I'll cast the Modul back to int and sort them via the arr.sort(function(a,b){ a=parseInt(a); b=parseInt(b); if(a.Modul>b.Modul){return 1;} if(a.Modul<b.Modul){return -1;}
