I'm getting a Parse error on line 6. It looks like my code is identical.

Hi my code looks identical to the code Alena has demonstrated yet I'm receiving this error:

Parse error: syntax error, unexpected '}' in /home/treehouse/workspace/catalog.php on line 6

line 6 is where the first else if starts

<?php 
$pageTitle = "Full Catalog";

if ($_GET["cat"] == "books") {
 $pageTitle = "Books" 
} else if ($_GET["cat"] == "movies") {
 $pageTitle = "Movies" 
} else if ($_GET["cat"] == "music") {
 $pageTitle = "Music" 
}

include("inc/header.php"); ?>   

<div class="section page">
<h1><?php echo $pageTitle; ?></h1>
</div>


<?php include("inc/footer.php"); ?>

Hi Patrick!

You're missing the semicolons on each of your "$page_tiitle = [category]" lines...

That section should look like this:

                if ($_GET["cat"] == "books") {
                    $page_title = "Books";
                } else if  ($_GET["cat"] == "movies") {
                    $page_title = "Movies";
                } else if  ($_GET["cat"] == "music") {
                    $page_title = "Music";
                }

I hope that helps.

BTW, I decided to refactor Alena's code a bit in order to keep all the header-related code in the header.php file.

So my header.php file now looks like this:

<!DOCTYPE html>
<html>
<head>

    <meta charset="utf-8">

    <?php
        $page_name = basename($_SERVER['PHP_SELF'], '.php');
        switch ($page_name) {
            case "catalog":
                $page_title = "Full Catalog";

                if (isset($_GET["cat"])) {
                    if ($_GET["cat"] == "books") {
                        $page_title = "Books";
                    } else if  ($_GET["cat"] == "movies") {
                        $page_title = "Movies";
                    } else if  ($_GET["cat"] == "music") {
                        $page_title = "Music";
                    }
                }

                break;

            case "suggest":
                $page_title = "Suggest Media";
                break;
            default: // index.php
                $page_title = "Media Library";
        }
        echo "<title>" . $page_title . "</title>";
     ?>
       <link rel="stylesheet" href="css/style.css" type="text/css">
</head>
<body>

    <div class="header">

        <div class="wrapper">

            <h1 class="branding-title"><a href="/">Personal Media Library</a></h1>

            <ul class="nav">
                <li class="books"><a href="catalog.php?cat=books">Books</a></li>
                <li class="movies"><a href="catalog.php?cat=movies">Movies</a></li>
                <li class="music"><a href="catalog.php?cat=music">Music</a></li>
                <li class="suggest"><a href="suggest.php">Suggest</a></li>
            </ul>

        </div>

    </div>

<div id="content">

And so now, so far, in the course, both my suggest.php file and my catalog.php file look like this:

<?php include("inc/header.php"); ?>

<div class="section page">
     <h1><?php echo $page_title; ?></h1>
</div>

<?php include("inc/footer.php"); ?>

Again, I hope that helps!

Stay safe and happy coding!

You're welcome!

Now my header.php file looks like this:

    <meta charset="utf-8">

                $page_title = "Full Catalog";
                $section = null;

                if (isset($_GET["cat"])) {
                    if ($_GET["cat"] == "books") {
                        $page_title = "Books";
                        $section = "books";
                    } else if  ($_GET["cat"] == "movies") {
                        $page_title = "Movies";

            </ul>

        </div>

    </div>

<div id="content">

And I didn't have to update the other three files at all!?! (And it works just fine!?!)
