I'm going to build a site for a client that consists of only one page. The page has only one div with editable content; the rest can be hard-coded in a template file.
The client wants CMS-like behavior: logging in on the site and editing that single piece of text (preferably inline). I usually build larger sites with Drupal, but that would be overkill for something simple like this.
Does anybody know of a good (open source) solution for a site like this?
It shouldn't be a large job to code this from scratch. All you need is admin.php with some kind of authentication and one form. I timed myself and made this in 7 minutes:
if(isset($_GET['login'])) {
// Check user credentials from db or hardcoded variables
if($_POST['username'] == 'user123' && $_POST['password'] == 'pass123') {
$_SESSION['logged'] = true;
} else {
$loginerror = 'Invalid credentials';
}
}
if(isset($_GET['logout'])) {
$_SESSION = array();
session_destroy();
}
if(!isset($_SESSION['logged']) || $_SESSION['logged'] !== true): ?>
<form method="post" action="admin.php?login">
<?php if(isset($loginerror)) echo '<p>'.$loginerror.'</p>'; ?>
<input type="username" name="username" value="<?php isset($_POST['username']) echo $_POST['username']; ?>" />
<input type="password" name="password" />
<input type="submit" value="Login" />
</form>
<?php endif;
if(isset($_SESSION['logged']) && $_SESSION['logged'] === true):
// Save contents
if(isset($_GET['save'])) {
file_put_contents('contents.txt', $_POST['contents']);
}
// Get contents from db or file
$contents = file_get_contents('contents.txt');
?>
<a href="admin.php?logout">Logout</a>
<form method="post" action="admin.php?save">
<textarea name="contents"><?php echo $contents; ?></textarea>
<input type="submit" value="Save" />
</form>
<?php endif;
Just combine those segments to get the full code. This code snippet has authentication, logout functionality and saves the contents of a textarea in a file. Alternatively you could change this so that users and content resides in database.
Personally, it would have taken longer for me to find an appropriate lightweight CMS and configure it to work.
Ok, here is my version of the CMS. You can find all my files here in a zip archive: http://chechi.be/midas/simple-cms.zip.
This is the admin page:

Have a look at TiddlyWiki. I'm not sure if this have login facilities etc, but It has all the major features of a small CMS.
Use Wordpress and create a simple theme. Wordpress has article history too so it's easy to go back if a mistake is made and so on.
I like Wordpress. It's techincally "blogging" software, but it's very easy to extend into a nice small CMS.
It's easy. You can code one in 10 minutes (or ask me).
Just a page with and admin file for editing text.txt.
