404'd! Custom errors
What if someone types in a bad URL? Or if something else goes wrong?
Yikes! That's pretty nasty! Don't worry, though, we can set something up to catch these.
Open up app/config/bootstrap.php and uncomment line that requires errors.php:
<?php
// ...
require __DIR__ . '/bootstrap/errors.php';
// ...
Now, if you hit a missing route, you should see something like:
This is the default Li3 Framework distribution error page, and it pretty much tells you what to do to make custom error pages :-) Let's open up app/views/layouts/error.html.php and have a look!
What I'd recommend doing now is making app/views/layouts/error.html.php and app/views/layouts/default.html.php similar - I created two elements (partial templates):
app/views/elements/header.html.php
<!doctype html>
<html>
<head>
<?php echo $this->html->charset(); ?>
<title>Employee Rolodex <?php echo $this->title(); ?></title>
<?php echo $this->html->style(array('bootstrap.min', 'lithified')); ?>
<?php echo $this->scripts(); ?>
<?php echo $this->styles(); ?>
<?php echo $this->html->link('Icon', null, array('type' => 'icon')); ?>
<style type="text/css">
/* This should really be in the css files but I've put
it here for simplicity's sake! */
body {
padding-top: 60px;
}
</style>
</head>
<body>
<div class="navbar navbar-inverse navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<ul class="nav nav-pills pull-right">
<li><a href="<?= $this->url(array('Home::index')); ?>">
Homepage</a></li>
<li><a href="<?= $this->url(array('Employees::index')); ?>">
Employees</a></li>
<li><a href="<?= $this->url(array('Administrators::login')); ?>">
Admin log in</a></li>
<li><a href="<?= $this->url(array('Administrators::logout')); ?>">
Log out</a></li>
</ul>
</div>
</div>
</div>
<div class="container">
<h1>Rolodex</h1>
<hr>
<div class="content">
Notice that I added "login"/"logout" links in the menu. Really, it should detect if you're logged in before showing it. TODO
app/views/elements/footer.html.php
</div>
<hr>
<div class="footer">
<p>Employee Rolodex</p>
</div>
</div>
</body>
</html>
app/views/layouts/default.html.php
<?= $this->_render('element', 'header'); ?>
<?php echo $this->content(); ?>
<?= $this->_render('element', 'footer'); ?>
Notice how it includes the header and footer using _render? We can do this in the error page too:
app/views/layouts/error.html.php
<?php
use lithium\core\Libraries;
$path = Libraries::get(true, 'path');
?>
<?= $this->_render('element', 'header'); ?>
<div class="content">
<h2>Something went wrong!</h2>
<?php echo $this->content(); ?>
</div>
<?= $this->_render('element', 'footer'); ?>
Great! Now our errors are rendered in the same style as the rest of our application :-)
Now would be a really good time to run the code quality static analysis ;-)
