<input id="niy" name="idate" value=""/>

 <?php
    $queryusersz = "SELECT * FROM invoice";
    $dbz = mysqli_query($con, $queryusersz);
    while($row = mysqli_fetch_array($dbz)) {
   $names[] = $row['idate'];      
    ?>
    
    <script>
    var array = <?php $names ?>;

$('#niy').datepicker({
    language:'TR',
    beforeShowDay: function(date){
        var string = jQuery.datepicker.formatDate('yy-mm-dd', date);
        return [ array.indexOf(string) == -1 ]
    }
});
    </script>
  <?php }?>
