echo alert not working

[robert_gsfame]

i have this code

if(!empty($_SESSION['username'])){

$val="window.location.href='test1.php'";}else{

$val="alert('Need login session')";}

 

echo "<input type=button value=Button onclick=$val>";

 

when i change the $val alert with alert('Login'), it works..... so the problem is that the alert cannot contain space..how can i do this?

 

 

 

thanks

change this:

echo "<input type=button value=Button onclick=$val>";

 

to this:

echo "<input type='button' value='Button' onclick=\"$val\">";
