Can Javascript be called from PHP?

[Steve]

Can Javascript be called from PHP? I was just trying to implement a little
print button that appeared if a certain condition was met like this:

<?

if ($reject=="0") {echo "<a href="javascript:print()""><img
src="images/print_button.gif" width="82" height="22" border="0"></a></p>;};

?>

but this fails spectacularly! I'm sure there is a good reason why - if only
I could poinpoint what it is!

Anybody care to enlighten me?

THANKS!

Steve

You can't put quotes in quotes!

Try

<?

if ($reject=="0") {
echo "<a href=javascript:print()><img src=images/print_button.gif width=82
height=22 border=0></a></p>";
}


?>
