PHP Session-Based Flash Messages

Store messages in session data until they are retrieved. Supports Bootstrap 4 or Bootstrap 5.

Notice

This is a forked version of new version of PlasticBrain's PHPFlashMessages - https://github.com/plasticbrain/PhpFlashMessages. This forked version has support for both Bootstrap V4 and Bootstrap V5

Features

  • Namespaced
  • PSR-4 autoload compliant
  • Installable with composer
  • Works with Bootstrap4 or Bootstrap 5
  • Fully customizable messages
  • URL redirects

Installation

With Composer

composer require Edydeyemi/php-flash-messages

Without composer

Download FlashMessages.php and save it to your project directory.

Import the file:

require '/path/to/FlashMessages.php';

Basic Usage

Default theme is Bootstrap V5. Pass 4 into the contructor to switch to Bootstrap V4.

// Start a Session
if (!session_id()) @session_start();
	
// Instantiate the class
$msg = new \Edydeyemi\FlashMessages\FlashMessages(); 
    or  
$msg = new \Edydeyemi\FlashMessages\FlashMessages(4); 

// Add messages
$msg->info('This is an info message');
$msg->success('This is a success message');
$msg->warning('This is a warning message');
$msg->error('This is an error message');


// If you need to check for errors (eg: when validating a form) you can:
if ($msg->hasErrors()) {
	// There ARE errors
} else {
  // There are NOT any errors
}
	
// Wherever you want to display the messages simply call:
$msg->display();

Message Type Constants

Each message type can be referred to by its constant: INFO, SUCCESS, WARNING, ERROR. For example:

$msg::INFO
$msg::SUCCESS
$msg::WARNING
$msg::ERROR

Redirects

It's possible to redirect to a different URL before displaying a message. For example, redirecting back to a form (and displaying an error message) so a user can correct an error.

The preferred method of doing this is by passing the URL as the 2nd parameter:

$msg->error('This is an error message', 'http://yoursite.com/another-page');

A redirect is executed as soon as the message it's attached to is queued. As such, if you need multiple messages AND need to redirect then include the URL with the last message:

$msg->success('This is a success message');
$msg->success('This is another success message');
$msg->error('This is an error message', 'http://redirect-url.com');

Helper Methods

hasErrors()

Check to see if there are any queued ERROR messages.

if ($msg->hasErrors()) {
    // There are errors, so do something like redirect
}

hasMessages ( [string $type] )

Check to see if there are any specific message types (or any messages at all) queued.

// Check if there are any INFO messages
if ($msg->hasMessages($msg::INFO)) {
    ...
}

// Check if there are any SUCCESS messages
if ($msg->hasMessages($msg::SUCCESS)) {
    ...
}

// Check if there are any WARNING messages
if ($msg->hasMessages($msg::WARNING)) {
    ...
}

// Check if there are any ERROR messages
if ($msg->hasMessages($msg::ERROR)) {
    ...
}

// See if there are *any* messages queued at all
if ($msg->hasMessages()) {
    ...
}

setCloseBtn ( string $html )

Sets the HTML for the close button that's displayed on (non-sticky) messages.

$msg->setCloseBtn('<button type="button" class="close" 
                        data-dismiss="alert" 
                        aria-label="Close">
                        <span aria-hidden="true">&amp;times;</span>
                    </button>')

setCssClassMap ( array $cssClassMap )

Sets the CSS classes that are used for each specific message type.

$msg->setCssClassMap([
    $msg::INFO    => 'alert-info',
    $msg::SUCCESS => 'alert-success',
    $msg::WARNING => 'alert-warning',
    $msg::ERROR   => 'alert-danger',
]);

setMsgAfter ( string $msgAfter )

Add a string of text (HTML or otherwise) after the message (but inside of the wrapper.)

For example, wrap a message in <p> tags:

$msg->setMsgAfter('</p>')

setMsgBefore ( string $msgBefore )

Add a string of text (HTML or otherwise) before the message (but inside of the wrapper.)

For example, wrap a message in <p> tags:

$msg->setMsgBefore('<p>')

setMsgCssClass ( [string $cssClass] )

Sets the CSS class that is applied to all messages, regardless of their type.

$msg->setMsgCssClass('alert')

setMsgWrapper ( string $html )

Sets the HTML that wraps each message. HTML should include two placeholders (%s) for the CSS class and message text.

$msg->setMsgWrapper("<div class='%s'>%s</div>")
