Question

First see my code.

   <select multiple name='assign_to[]'>
                    <?
                $result_10 = mysql_query("select * from login_users") or die(mysql_error());
                while($row_10 = mysql_fetch_object($result_10))
                {
                    echo "<option  value=".$row_10->user_id.">".$row_10->username."</option>";
                }
                ?>
    </select>

I am able to get value when page is submitted no issue with this but my problem is :

When page is submitted I am redirecting to the same page then I want that options which are selected before submitting the form will seen selected after page is submitted.

What PHP code is to written there. What I did for single selected drop down as :

<?
while($row_10 = mysql_fetch_object($result_10))
                    {
?>
       <option <?=$row_10->user_id==$_POST['assign_to']?'selected':''?> value="<?=$row_10->user_id?>"><?=$row_10->username?></option>
<?
                    }

?>

Hope you are getting my question ?

Thanks!!!

Answer 1

if(in_array($row_10->user_id,$_POST['assign_to'])){echo "selected"}else{echo ""}

As your $_POST[‘assign_to’] is an array i guess this will work.

OR you can use conditional operators :

<option <?= in_array($row_10->user_id,$_POST['assign_to']) ? 'selected' : ''?> value="<?=$row_10->user_id?>"><?=$row_10->username?></option>
