• Bootstrap (default)
• Foundation
• Bulma
• Materialize
• Tailwind
• Premier
• UIKit
• Semantic UI
• Spectre.css
• Halfmoon

Install

Via Composer.

$ composer require tamtamchik/simple-flash

Inside your project make sure to start a session and load Composer autoload to make everything work.

<?php
// Start a Session
if( !session_id() ) {
    session_start();
}

// Initialize Composer Autoload
require_once 'vendor/autoload.php';

Usage

There are 3 ways to use library:

use \Tamtamchik\SimpleFlash\Flash;
use function Tamtamchik\SimpleFlash\flash;

// Instance
$flash = new Flash();
$flash->message('Tea.');

// Static
Flash::message('Earl Gray.');

// Function
flash()->message('Hot!');

Messages added by calling message($message, $type = 'info') method. In case of calling a function flash() you can pass $message, $type just to function like so: flash('resistance is futile').

Because any of creation types return \Tamtamchik\SimpleFlash\Flash instance, so you can always use chaining to add multiple messages. Shortcuts available for all types of base message types, also you can pass arrays as $message.

use function Tamtamchik\SimpleFlash\flash;

flash()->error(['Invalid email!', 'Invalid username!'])
       ->warning('Warning message.')
       ->info('Info message.')
       ->success('Success message!');

Out of the box library support 4 different types of messages: error, warning, info, success.

<div class="alert alert-danger" role="alert">
  <p>Invalid email!</p>
  <p>Invalid username!</p>
</div>
<div class="alert alert-warning" role="alert"><p>Warning message.</p></div>
<div class="alert alert-info" role="alert"><p>Info message.</p></div>
<div class="alert alert-success" role="alert"><p>Success message!</p></div>

Rendering is simple:

use function Tamtamchik\SimpleFlash\flash;

// Rendering specific type
$output = flash()->display('error');

// Rendering all flash
$output = flash()->display();

// Also rendering possible when you just read instance of \Tamtamchik\SimpleFlash\Flash object as a string
(string) flash();

// or ... it's totally just for display, never do this in real life...
<?php
// ... some code
$flash = new Flash();
$flash->warning('It is totally just for display, never do this in real life...');
// ... some other code
?>
<!-- ... some html -->
<div class="flashes">
  <?= $flash; ?>
</div>
<!-- ... some other html -->

Templates

Using templates you can customize how flash messages will be rendered. Package comes with a set of templates for most popular CSS frameworks:

Templates::BASE; // Same as Templates::BOOTSTRAP
Templates::BOOTSTRAP;   // https://getbootstrap.com
Templates::FOUNDATION;  // https://get.foundation
Templates::BULMA;       // https://bulma.io
Templates::MATERIALIZE; // https://materializecss.com
Templates::TAILWIND;    // https://tailwindcss.com
Templates::PRIMER;      // https://primer.style
Templates::UIKIT;       // https://getuikit.com
Templates::SEMANTIC;    // https://semantic-ui.com
Templates::SPECTRE;     // https://picturepan2.github.io/spectre
Templates::HALFMOON;    // https://www.gethalfmoon.com

Shortcuts

You cah pass template name as a second argument to display() function:

use function Tamtamchik\SimpleFlash\flash;

flash()->success('Success message!');
...
// rendering with Halfmoon template using Templates::HALFMOON as a shortcut
echo flash()->display('success', Templates::HALFMOON);

Or you can use descriptive display functions:

use function Tamtamchik\SimpleFlash\flash;

flash()->success('Success message!');
...
echo flash()->displayBootstrap();
echo flash()->displayFoundation();
echo flash()->displayBulma();
echo flash()->displayMaterialize();
echo flash()->displayTailwind();
echo flash()->displayPrimer();
echo flash()->displayUiKit();
echo flash()->displaySemantic();
echo flash()->displaySpectre();
echo flash()->displayHalfmoon();

Factory

Package comes with a set of templates for most popular CSS frameworks:

This templates can be created using TemplateFactory that comes with package. All templates have aliases defined in Templates.

use Tamtamchik\SimpleFlash\Flash;
use Tamtamchik\SimpleFlash\TemplateFactory;
use Tamtamchik\SimpleFlash\Templates;

// get template from factory, e.g. template for Foundation
$template = TemplateFactory::create(Templates::FOUNDATION);

// passing template via function
flash('Info message using Foundation 6 template!', 'info', $template);

// passing to constructor
$flash = new Flash($template);

// using setTemplate function
$flash->setTemplate($template);

Creating templates

Template is basically any class that implements TemplateInterface. But to make it easy you can extend BaseTemplate, it already contains most of the functions.

Defining and using this sample class as template:

use Tamtamchik\SimpleFlash\BaseTemplate;
use Tamtamchik\SimpleFlash\TemplateInterface;
use function Tamtamchik\SimpleFlash\flash;

class CustomTemplate extends BaseTemplate implements TemplateInterface
{
    protected $prefix  = '<li>'; // every line prefix
    protected $postfix = '</li>'; // every line postfix
    protected $wrapper = '<ul class="alert-%s">%s</ul>'; // wrapper over messages of same type

    /**
     * @param $messages - message text
     * @param $type     - message type: success, info, warning, error
     *
     * @return string
     */
    public function wrapMessages($messages, $type)
    {
        return sprintf($this->getWrapper(), $type, $messages);
    }
}

flash()
    ->setTemplate(new CustomTemplate)
    ->error(['Invalid email!', 'Invalid username!'])
    ->warning('Warning message.')
    ->info('Info message.')
    ->success('Success message!')
    ->display();

Will output following:

<ul class="alert-error">
    <li>Invalid email!</li>
    <li>Invalid username!</li>
</ul>
<ul class="alert-warning">
    <li>Warning message.</li>
</ul>
<ul class="alert-info">
    <li>Info message.</li>
</ul>
<ul class="alert-success">
    <li>Success message!</li>
</ul>

Interface
