ci-flash

A small CodeIgniter library which provides extended flash message functionality.

What's Included:

• Custom message types, along with the option to display the message on the current page request.
• Ability to provide custom styling based on the message type.
• Allows you to define which message types to display on output, as well as if they should be merged into single notices (per message type) or not.
• An easy interface to interact with form validation errors.

Usage

If you are using the Sparks package manager:

$this->load->spark('flash/x.x.x');

Or if you are still rocking it old school:

$this->load->library('flash');

Styling

A couple of predefined styles are provided in the configuration file, but more can be easily added. The example style below will add a style for the message type new_style with <div class="alert"> prepended and </div> appended to the displayed output.

// file: config/flash.php
$config['flash']['styles']['new_style'] = array('<div class="alert">', '</div>');

Adding

To define the type of message, you call the desired name type as the function name, passing in the message contents.

$this->flash->success('Successfully updated the record.');

Or if you wish to display a info message this page request with a single printf placeholder.

$this->flash->info_now('This is some useful %s.', 'information');

Screw it, lets make it a awesome message with multiple placeholders.

$this->flash->awesome('This is a %s %s', array('awesome', 'message'));

Retrieving

To display all the messages, split into each individual message type (i.e. in a view).

echo $this->flash->display();

Or to display only the success messages, with a default override of splitting each message into its own styled alert.

echo $this->flash->display('success', TRUE);

If you do not wish to display all the messages and want to get your hands on an array to play with.

$messages = $this->flash->get();

Alternatively, you can specify which type of message you wish to retrieve.

$success_messages = $this->flash->get('success');
// or using the __get magic method
$error_messages = $this->flash->error;

Form Validation Errors

The library also provides a wrapper to easily access and display form validation errors. Thease types of errors can be displayed either using the special message type form or merged with other error messages.
