JavaScript Question

FrozNic

k, i know this a php board 🙂 but, someone HAS to know javascript at least a little bit. all i'm trying to do is a pass a variable into javascript.. and i'm completely stumped.. here's the code:

<?php
$a = '3';
?>

if (a > <?php echo $a; ?>) alert('Article '+a+' has been emailed to you.');

it doesn't work, and i don't know how to make it work... any ideas? thoughts? thanks...

i just thought that maybe javascript doesn't even know a variable in php exhists cuz it's client side.. .. thoughts? thanks

<?php 
$a = '3'; 

if (a > $a) 
{
echo "<script language='javascript'>";
echo "alert('Article '+a+' has been emailed to you.')";
echo "</script>";
}
?>

It might need some tweeking. 🙂

never mind, i got it.. here's the code if anyone ever needs to know how i did it:

<html>
<head>
<title>Untitled Document</title>


<SCRIPT LANGUAGE="javascript">
var a = 0;
function too_many() {
	for (var j = 1; j <= 6; j++) {
	box = eval("document.checkboxform.C" + j);
	if (box.checked) a++;
	}
if (a > (document.checkboxform.bob.value)) alert('Article '+a+' has been emailed to you.');	
}
</SCRIPT>
</head>

<body>
<?php
$ab = 3;

?>
<form name=checkboxform>
<input type="hidden" name="bob" value="<? print $ab; ?>">
<input type=checkbox name="C1" onClick="too_many()">C1<br>
<input type=checkbox name="C2" onClick="too_many()">C2<br>
<input type=checkbox name="C3" onClick="too_many()">C3<br>
<input type=checkbox name="C4" onClick="too_many()">C4<br>
<input type=checkbox name="C5" onClick="too_many()">C5<br>
<input type=checkbox name="C6" onClick="too_many()">C6<br>
</form>
</body>
</html>
