[RESOLVED] can I do this with php?

lukeurtnowski

I'm trying to create a function which would check too see if a variable was set, and output certain html code if it was, and output some other html code if it wasn't
here's my html code

<select name="country" onChange="checkCountry()"> ........</select>

heres the javascript function
function checkCountry() {
var ctry = document.form1.country[document.form1.country.selectedIndex].value;
if (ctry == "USA") {
document.write(<p><label>State</label><input type=text name=state></p>);
} else {
document.write(<p><label>Country</label><input type=text name=country></p>);
}
}
Thanks!
(is there another easier way to do this using php?)

If your going to use PHP within HTML, it would be like this:

<select name="country" onChange=<? checkCountry(); ?>> ........</select>

lukeurtnowski

so then the function checkCountry() can be a php function and not a javascript function?
How would I then grab the select box'es value, I can use php for that, I thought only javascriipt works.
Thanks

javascript is clientside
php is serverside

Therefore you probably wants to use the js solution if you want the variable to be checked without reloading the page like in this instance.
Only if you submit the page, php can reach it. Could be somehting like

$errors = false;

if (isset($_POST['country']))
{
	if ((isset($_POST['country'])) && ($_POST['country'] == "usa"))
	{
		if (isset($_POST['state']))
		{

	}
	else
	{
		$errors = true;
	}
}
else
{
	$errors = true;
}	
}

if ($errors == false)
{
	// do something like saving
}

Yea, I tried something like that but ran into problems, is it possible to have a form within a form, like this?
<form method=post>
...
....
...
<form method=get>
....
</form>
.....
.....
....
</form>

how would you use the form inside the form?

oh, use quotes in your html tags:
<form method="GET">

no you cannot have another form inside your form

Oh, Ok. I figured out hoow to do it with javascript (onChange()). But figured since php is the bomb, it would be a betterif I could use it. But I'lll just stick with javascript then.
Thanks
