Changing PHP list link color

crystalattice · #1 20-Jan-2006, 19:45

Not sure how to fix this one. I have a dynamically generated navigation bar and I want to change the default link color. Right now it's the standard blue/purple link colors but I can't figure out how to make the colors change.

I've tried changing the .css file the php script accesses but that only changes the bullet colors; apparently because the list is dynamically made it doesn't "understand" CSS.

Here's the CSS file:

CSS Code:

.box {
	width: 140px;
	margin-top: 3px;
	padding: 0 0 0 0;
	border: 1px solid #000;
	background-color: #999966;

}

.box h3 {
	color: #27282A;
	border-bottom: 1px solid #000;
	padding-left: 2px;
	padding-right: 2px;
	margin: 0 0 0 0;
	background-color: #809966;
}

.box ul {
	margin: 0 0 0 10px;
	padding: 0 0 0 10px;
}

.box ul ul {
	margin: 0 0 0 7px;
	padding: 0 0 0 7px;
}

.box p {
	padding: 3px;
	margin: 2px 0px 2px 0;
	text-align: center;
}

.box a img {
	border: 0px;
	margin: 2px;
}

.rssbutton {
    margin-left: 5px;
}

.breadcrumbs {
    font-size: 80%;

}

.extendedinfo {
    color: gray;
}

Here's the PHP file I'm using:

PHP Code:


<!-- <alexpounds:noList /> -->

<?

include_once($_SERVER["DOCUMENT_ROOT"] . "/gfFunctions.php");
include_once($_SERVER["DOCUMENT_ROOT"] . "/userinfo.php");

function buildInnerNav($currentPath) {

    $file = getCurrentFile($currentPath, FALSE);
    $dir = getCurrentDir($currentPath);
    $pathDir = $_SERVER["DOCUMENT_ROOT"] . $dir;
    $parentPath = getParentDir($currentPath);

    if ($dir != "/") {
        buildOuterNav($parentPath, $currentPath, TRUE, 0);
    }
    
    if ($dir !== FALSE && $file !== FALSE) {
        if ($dh = opendir($pathDir)) { // Open directory.
            echo "<ul>\n";
            // If we're in the root, add a "Home" link as we discard the index file in the loop below.
            if ($dir == "/") { 
                if ($file == "index." . $myExtension) {
                    echo "<li><b>Home</b></li>\n";

        buildOuterNav($parentPath, $buildPath, FALSE, $level+1);
    }
}
 
echo "<h3>Navigation</h3>\n";
buildInnerNav($_SERVER["PHP_SELF"]);

?>

Is there an easy way to fix this or should I just live with it?

Hey Cody, do you have a "live" page showing this problem?

Assuming this is the markup:

HTML Code:


<div class="box">
	<ul>
		<li><a href="/">Home</a></li>
		<li><a href="/dir-1/">Directory 1</a></li>
		<li><a href="/dir-1/subdir-1/">SubDirectory 1-1</a></li>
		<li>Web Page in Sub Directory 1-1</li>
	</ul>
</div>

Update your stylesheet inserting something like this (assuming you want the links to be white):

CSS Code:

div.box li a:link	{ color:white; text-decoration:none; }
div.box li a:visited	{ color:silver; text-decoration:none; }
div.box li a:active	{ color:yellow; text-decoration:none; }
div.box li a:hover	{ color:white; text-decoration:underline; }

Sorry, it's on an internal server that's not configured for "world access". I can show you screen shots, if you like.

I'll try what J suggested and see what happens.

Hey thanks, J. It's working now. I didn't realize I needed the li tag for each link; I only remember using a:hover etc. the last time I did color changes.
