    resolved [RESOLVED] Extra white-space in textarea

    I keep getting this extra white-space when I load content from a mysql database into a textarea of a form. I've tried converting it into a string a then use the trim() function but I keep getting the same problem. Any ideas?

    PHP Code:
    <?php
    include "admin/conn/config.php";
    include 
    "admin/conn/connect_database.php";
    $page_update "";
    if (isset(
    $_POST['update'])){
        
    $update $_POST['update'];
        
    $sql="UPDATE updates SET message='$_POST[update]', date=CURDATE()";
        if (!
    mysql_query($sql,$opendb)){
            die(
    'Error: ' mysql_error());
         }
        else {
            
    $page_update "<h2>Sidan har blivit uppdaterad!</h2>";
        }
    }
    ?>

    </head>

    <body>
        <?php
        $result 
    mysql_query("SELECT * FROM updates ORDER BY date DESC LIMIT 1");
        
    $row mysql_fetch_array($result);
        echo 
    $row['message']." (".$row['date'].")";
        echo 
    $page_update;
        
    ?>
        <form action="" id="" method="post">
            <textarea cols="60" rows="10" name="update">
            <?php
            $result 
    mysql_query("SELECT * FROM updates");
            
    $row mysql_fetch_array($result);
            
    $str $row['message'];
            echo 
    trim($str);
            
    ?>
            </textarea>
            <br />
            <input type="submit" value="Spara" class="krs-edit_align-r"/>
      </form>
    </body>
    </html>

    Remove the newlines/spaces between the <textarea> tags and the <?php tags:
    PHP Code:
            <textarea cols="60" rows="10" name="update"><?php
            $result 
    mysql_query("SELECT * FROM updates");
            
    $row mysql_fetch_array($result);
            
    $str $row['message'];
            echo 
    trim($str);
            
    ?></textarea>

    Is there a better way of putting out the $page_update = "<h2>Sidan har blivit uppdaterad!</h2>"?

    Now I have an empty variable that first outputs nothing until the form has been submitted. With javascript or something?
