<iframe>中的查询字符串

I am trying to call a query string in <iframe>. I tried different ways. When I run the script ill get:

Notice: Trying to get property of non-object in C:\Program Files (x86)......\print.php on line 184

Something in src="./print.php?id='. $_GET['id'] .'" goes wrong. I tried to access print.php?id=25 and there where also no errors on that page.

Does anybody know whats wrong with my code?

<?php 
if (isset($_GET['id'])) 
{ 
    ?>
<iframe width="100%" height="900px" src="./print.php?id='. $_GET['id'] .'"></iframe>
<?php
}
?>

    In html code you use $_GET[]?!

    try this

    <?php 
    if (isset($_GET['id'])){ 
    ?>
        <iframe width="100%" height="900px" src="./print.php?id=<?php echo $_GET['id']; ?>"></iframe>
    <?php
    }
    ?>
    

    or

    <?php 
    if (isset($_GET['id'])) { 
       echo '<iframe width="100%" height="900px" src="./print.php?id='.$_GET['id'].'"></iframe>';
    }
    ?>
