variable not getting passed correctly

[fluxus]

Hi,

I am having problem with conditional code not executing correctly now that I've put it into a function.

At the top of my document I set the current page with a variable:
<?php $currentpage = "contact"; ?>

...then I show my function to write out a nav bar link:

<?php
function nav_child($PageLabel, $PageName, $PageURL, $PageAlt="") {

global $SkinDir;

echo "<tr>";
echo "<td><img src='$SkinDir/spacer.gif' width='1' height='1' border='0'></td>";
echo "<td valign='middle' nowrap='nowrap' height='11'>";

if ( $currentpage == "home" ) { 
	// Link Turned ON (BLUE)
	echo "<img align='center' src='$SkinDir/nav2_bullet_on.gif' height='11' alt='$PageAlt' border='0'>";
} else {
	// Link Turned OFF (WHITE)
	echo "<a class='noline' href='$PageURL' target='_self'>";
	echo "<img align='center' src='$SkinDir/nav2_bullet.gif' height='11' alt='$PageAlt' border='0'></a>";
} 
if ( $currentpage == "home" ) {
	// Link Turned ON (BLUE)
	echo "<span class='nav2on'>$PageName</span>";
} else {
	// Link Turned OFF (WHITE)
	echo "<a class='noline' href='$PageURL' target='_self'>";
	echo "<span class='nav2'>$PageName</span></a>";
} 
echo "</td>";
echo "</tr>";	
}

?>

...later on, when I write out the nav bar...

<?php nav_child("home", "Home", "index.php", "Home...");	?>

<?php nav_child("about", "About Us", "about.php", "About...");	?>

<?php nav_child("contact", "Contact Me", "contact.php", "Contact Info...");	?>

The CONTACT link should show up blue with a different image/CSS class since the $currentpage variable is set to "contact" but it all 3 links show up the same.

Before I converted the code into a function, it all worked.
Please help me, I'm new to PHP and very clueless!

Thx,
Jeremy

Have you tried adding "global $currentpage" within the nav_child function?

Hi,

I tried adding global $currentpage; inside the function before and again now, but no luck.

Any other ideas...

Thanks!

You need to pass $currentpage to the function or it can't use it.
Define the function something like this:

function nav_child($PageLabel, $PageName, $PageURL,$currentpage, $PageAlt="") 

Then call it like this:

nav_child("home", "Home", "index.php", "$currentpage","Home...");

Thanks so much for your help!
That took care of it. I really appreciate it.
