javascript..how i hate it...

[Cicada]

simple thing really..

i have 2 select thingys, both feeding data from a php script / database thingy...

now they're related, so what happens in the first one, i want to affect what the options are for the second one. Now i want to do this without having to sumbit the form, and i know javascripts the way to do it..

prolly using onchange i guess...but if anyone can help it'd be nice..

i read it, i just couldn't figure out how to 'convert' that code into 2 selects as opposed to 1 select and a text area..

[Cicada]

heres the code that i worked out to kinda do it..

$shows=array();
$seasons=array();
	
$count=0;
$query="select * from shows";
$result= mysql_query ($query);
while ($row=mysql_fetch_array($result))	{
	$shows[$count]=$row[name];
	$seasons[$count]=$row[seasons];
	$count++;
}
	
?>

<select name="user">
<option value="0">Choose</option>
<?
for ($i=0;$i<$count;$i++) {
	echo "<option value=".$i.">".$shows[$i]."</option>";
}
?>
</select>

<select name="details">
<?
for ($i=1;$i<=$seasons[$z];$i++) {
	echo "<option>Season ".$i."</option>";
}
?>
</select>
<?

now all i need is some jscript to change the value of $z depending on what the value is changed to in the 'user' select

Ah that's a point sorry. It's also something I don't know either :-(

Step 1. Work out how to alter a set of options in Javascript that works on the browsers you want it to work on.
Step 2. Work out how to embed the information you want in Javascript from PHP so that selecting a option from the first select sets the options in the second select.
Step 3. Provide a decent default from browsers without Javascript. This should be easy if it's just numbers.

Which step gives you trouble?
