All, on page 277 creating pagination, how can or what is the best way to customize this script for articles or any other content wanting to be displayed through pagination. Please help.

In the following line, you're assigning a class (as I suspected):
if ($this_page == $v) echo ' class="selected"';
Are you sure this isn't the issue with "Home" being blue?

<link href="../css/styles.css" rel="stylesheet" type="text/css" />
<style id='flashfirebugstyle' type='text/css'>object,embed{visibility:hidden !important;}</style></head>
<body>
<div id="wrap">
<div class="header">
	<!-- TITLE -->

	<h1><a href="index.php">Knowledge is Power</a></h1>
	<h2>and it pays to know</h2>
	<!-- END TITLE -->
</div>
<div id="nav">
	<ul>
		<!-- MENU -->
		<?php // Dynamically create header menus...

		// Array of labels and pages (without extensions):
		$pages = array (
			'Home' => 'index.php',
			'About' => 'about.php',
			'Contact' => 'contact.php',
			'Register' => 'register.php'
		);

		// The page being viewed:
		$this_page = basename($_SERVER['PHP_SELF']);

		// Create each menu item:
		foreach ($pages as $k => $v) {

			// Start the item:
			echo '<li';

			// Add the class if it's the current page:
			if ($this_page == $v) echo 'class="selected"';

			// Complete the item:
			echo '><a href="' . $v . '"><span>' . $k . '</span></a></li>

			';

		} // End of FOREACH loop.
		?>
		<!-- END MENU -->
	</ul>
</div>
<div class="page">
	<div class="content">

		<!-- CONTENT -->

Yes, it could be (class = "selected")-**blue text** kinda strange in code view, but I guess. But why are the codes being displayed vs the links and tabs (images). I have check several times too make sure that I have not left nothing out or mistype any codes. Then I just copied from source files and still get the codes displaying not the links and tab images. The page heading is displaying along with the color that's outline in the css file. I will troubleshoot some more, maybe I'm still doing something wrong.

Hello,

Just a quick note, don't post your passwords and usernames

Once I realized what I had just did, I change them. Thanx.

Sorry, but that's not what I meant.

For example, please load your page into the browser, and from the browser's view source option, please copy the relevant HTML. Thank you.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<head>

<title><?php // Use a default page title if one wasn't provided...

if (isset($page_title)) {

echo $page_title;

} else {

echo 'Knowledge is Power: And It Pays to Know';

}

?></title>

</head>

<body>

<h1><a href="index.php">Knowledge is Power</a></h1>

</div>

<ul>

<?php // Dynamically create header menus...

// Array of labels and pages (without extensions):

$pages = array (

'Home' => 'index.php',

'About' => 'about.php',

'Contact' => 'contact.php',

'Register' => 'register.php'

);

// The page being viewed:

$this_page = basename($_SERVER['PHP_SELF']);

// Create each menu item:

foreach ($pages as $k => $v) {

// Start the item:

echo '<li';

// Add the class if it's the current page:

if ($this_page == $v) echo ' class="selected"';

// Complete the item:

echo '><a href="' . $v . '"><span>' . $k . '</span></a></li>

';

} // End of FOREACH loop.

?>

</ul>

</div>

'index.php', 'About' => 'about.php', 'Contact' => 'contact.php', 'Register' => 'register.php' ); // The page being viewed: $this_page = basename($_SERVER['PHP_SELF']); // Create each menu item: foreach ($pages as $k => $v) { // Start the item: echo '' . $k . ' '; } // End of FOREACH loop. ?>

Instead of text links being displayed on header.html, the above text is being displayed.

krobinson937, I ran into a similar issue in that my buttons looked nothing like Larry's, and then I realized that there are images for each of the buttons. Make sure you download the images (included with the source code for the first example site) and put them in the proper folder. After that, things should work.

As for the colors, well, I can't comment with more details, but are you applying some sort of class definition to the home element?

No definition, just outline on page 65 4.Create an array of pages:

$pages = array(

'Home' => 'index.php',

'About' => 'about.php',

'Contact' => 'contact.php',

'Register' => 'register.php'

);

Home link stays blue and all other links turns black. Keep in mind I'm using DW3.

You're not really providing enough information here (see the guidelines), but if you're loading header.html directly in your browser, you're going to see the raw code.

Also, to be clear, this book does assume complete comfort with PHP and MySQL.

I'm fine with PHP, we are using your PHP and MySQL @ Cincinnati State, also have I all your latest books. I'm using DW3 for design tool. On page 65 when setting up the array for home, about, contact, and register; the home text stays blue and all other text turn black. I have look for any missing quotes or other mis-type syntax, finally, I just copied header.html from source files. Another issue, I'm having problems with my css/images (the tab images) not showing up on main nav when viewing from in preview mode from Dreamweaver 3. I have check my file structure.

June 29, 2011

I'm having problems with my text or syntax. I'm currently working on page 65, when I go to setup the array for the list some words are blue and are black. When I go to display header.html in firfox, I see the raw code in browser not the tabs nor text color outline by style sheet. Any ideas?
