I agree that this is a little bit confusing. I wrote this a long time ago as a reference for myself. And now I'm wondering "What was I thinking?" :)

When I say put something in something else, I usually mean in between curly brackets { }

Each line of code I show will generally go in the order in which they are shown. For example:

function title() {
    if ($_GET['id']) {
        $pageID = (int) $_GET['id'];
 
        $result = mysql_query("SELECT title FROM pages WHERE id='$pageID'");
        $row = mysql_fetch_array($result);
 
        echo $row['title'];
    } else {
        $result = mysql_query("SELECT value FROM settings WHERE name='homeTitle'");
        $row = mysql_fetch_array($result);
 
        echo $row['value'];
    }
}

I'm sorry but this is confusing. After you say put this code in for the function title()

you don' t say where to put anything else. You say put this in the if block- but what do you mean? i think what would help too, is that at the end of each lesson you show an overall of what our code should look like after that lesson. You are doing a great job, there is just a little confusion with some things, and I cannot move forward.

@kt: Thanks for pointing that out. I forgot a quote in the pre tag.

after this section, there is no code. looks like a

 tag is not closed in your html? :

Page Title
Paste the code inside of the title function into the pageTitle function. Inside the else section, replace 'homeTitle' in the MySQL query with 'homePage', and delete the line containing
echo $row['value'];
and add in
*** NOTHING HERE***

Duane: What about config.php? Make sure that your database user has proper permissions for the database.

the value is correct its pretty much a copy and paste from your tutorial.

Duane: What is the value of $result? It looks like that variable is the problem. Or it could be a problem with the database.

Also, try checking the database in config.php, and make sure everything is correct.

ok, i've done that now, but for some reason its having problems connecting to the database

$row = mysql_fetch_array($result); has an error :S

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/paganc/public_html/Duane-Folder/functions.php on line 23

I used the script in the zip file. and get that error.

Duane: It looks like a syntax error. If you are comparing the values, '$homeTitleID = (int) $_GET['id']' needs to be wrapped in parentheses, and the '=' needs to be '==', because '=' is an assignment operator, and '==' is a comparison operator. You can check Part 7, because there is a link to download the entire project, and you can take a look at functions.php if you are not sure what to do.

Oops, erm it didn't paste everything :(

erm, if $homeTitleID = (int) $_GET['id']; is on line 14.
