passing variables into javascript.

[supersteve3d]

I read another thread that seems to indicate that what I want to do can be done in php. I am quite new to php.

my page is at http://www.stevelim.com/links/links.html

what I am trying to do is pass parameters from other pages which will determine which CSS id to hide and show.

here is the code that I think I should be using..

<?php if($_GET["type"] == "friends"){
?> 
	<div id="friends" style="display: ''">
	<?php
	} else {
	<div id="friends" style="display: 'none'">
	?>

	<?php
	}
	?>

I get a parse error.

Thanks.

<?php if($_GET["type"] == "friends"){
?> 
    <div id="friends" style="display: ''">
    <?php
    } else {
    ?>
    <div id="friends" style="display: 'none'">

    <?php
    }
    ?>

Personally, I find it easier to follow the code by not going in and out of PHP mode all the time, but that's more a matter of taste. Here's a cleaner way to do it:

<?php
$style = ($_GET["type"] == "friends") ? '' : 'style="display: none"';
echo "<div id=\"friends\"$style>\n";
?>

NogDog! Thank you! It works wonderfully... amazing this php. I'm often confused where javascript is needed and where php plays its role. I guess there is quite alot of overlap.

As an aside. If I were to get greedy, may I ask if it is possible to sort and rearrange the html such that the variable type passed to the page gets listed first?

Thanks again!

Argh. sorry, I just noticed one more thing.

Currently its a if / else thing. What if no type is sent at all? i would like all categories to be open as in my old page.

Should I simple make a 3rd else statement?

I think I just need the syntax for the following pseudocode..

$style = ($_GET["type"] == "friends" OR _no type exists) ? '' : 'style="display: none"';

I got this to work using the following code.

I guess I will address the sorting another time.

<?php
$style = ($_GET["type"] == "friends" || $_GET["type"] == "") ? '' : 'style="display: none"';
echo "<div id=\"friends\"$style>\n";
?>
