Warning

I want to ensure you see this warning message, which is why it is first and before the installation instructions.

The icon and message will NOT be escaped/encoded.

For the icon, this shouldn't be a problem since they are generated from the config and are an array map. However, you should be aware of it just in case you do (for some crazy reason) use user input in the icon passed to the individual message's config array.

For the message, in most cases, it shouldn't be a problem. This allows you to use HTML inside of the message itself, so you can include a link, underline or bold something, make a list, whatever you need.

You can use a user's data that is generated by your application, like their user id.

If, for some crazy reason, you do need to pass user input into the message, you SHOULD encode it using Laravel's e() helper function. Not the whole message, just the individual pieces of data you are inserting into it, like their name. If it's questionable, encode it. Read:https://laravel.com/docs/10.x/blade#html-entity-encoding

Installation

To install this package, run:

Place the code for the container component where you want the flash messages to appear.

Note: If you want to display the flash messages on multiple different types of layouts, you will want to wrap a <div> around the call to the component. This way you can use a different wrapper on your login/register pages and your dashboard.

Example:

and

This package supports Tailwind v2 (comes with Laravel 8 by default), Bootstrap v4, and Bootstrap v5 out of the box.

Due to this flexibility, we can't load an appropriate config or view files by default. So you will get an error if you do not install them.

Follow the instructions below for the appropriate CSS environment you are using.

Tailwind v2

Other CSS Templating

If you are not using Bootstrap or Tailwind, then just pick any of them and modify the generated files however you need.

In the future when newer versions of Tailwind or Bootstrap are out, just choose the latest appropriate version and modify it if necessary. Depending on how much the future versions change, depends on how much you have to modify.

Installing Icons

A default Laravel installation does not include FontAwesome, so the icons will not work. You are free to use whatever icons you want, you will just have to modify the config to use them. If you are using a 3rd party template of some kind, ensure that FontAwesome isn't already installed. You can simply try using an icon on a view file somewhere.

If you want to use FontAwesome, you must first install it. You have 2 options, CDN or NPM :)

Install FontAwesome via CDN

In all of the layouts you want to use flash messages on, add the stylesheet to the head section:

Then add the corresponding JavaScript file just before the closing body tag:

Install FontAwesome via NPM

Then import it in your resources/css/app.css file:

Require it in your resources/js/app.js file:

Finally, run:

Info about the view files

The view files will be published to resources/views/vendor/flashmessages.

The container component blade file: It is a container that holds the individual flash messages. It simply loops through all the flash messages and loads them each into their own components.

The message component blade file: The template for each flash message itself. There are a few helper functions available to assist with generating the message. Use the helper functions and do not echo the variables directly. The helper functions return an empty string if the value is not set (null).

Usage

A Composer alias is made for the FlashMessages Facade so you don't have to import it manually, but you still can.

Use the backslash and you don't have to import it: \FlashMessages::addFlashMessage($type, $message)

Or, you can import it at the top of your class simply as: use \FlashMessages;

Or, you can import it like you do for everything else as: use CyberPunkCodes\FlashMessages\Facades\FlashMessages;

Now all you have to do is add the flash message:

You can also use the flash() macro on a redirect in your controller:

Example:

If you need to pass specific options, you can pass an config options array as the 3rd parameter. You will need to do this to override any default/global settings defined in the config. For example, if globally your flash messages are dismissable, you can force an individual message to not be dismissable:

This will probably be the preferred method to use, unless you need to add more than 1 flash message. In that case, you will need to use the Facade for each message. On the next page load, all of the flash messages will display.

Safely using user input/data

Please read the big warning that is at the beginning of this README. The message is not encoded by blade's {{ $message }} rendering tags. The message is rendered using {!! $message !!} so HTML can be used.

If you need to pass user data into the message, here is how you can safely do it:

Advanced Usage

Add Flash Message Now

In addition to the addFlashMessage() method, there is also addFlashMessageNow() to render messages for immediate use. It utilizes Laravel's request()->session()->now(), which allows you to add a flash message and display it on the same page load.

I added this because I wanted to convert the built in status messages to nice Bootstrap alerts (flash messages). For example: When email verification is enabled, Laravel returns a verification-link-sent status. This isn't very easy to work with. At this point, the page has already loaded and or been redirected to wherever it's supposed to go. Since the page has already loaded, if we use addFlashMessage() at this point, the flash message will display on this page load AND the next. That is a problem, the message shouldn't be shown on the next subsequent page.

To solve this, we can use addFlashMessageNow() instead:

I wrote a middleware that simply detects all of the generic Laravel and Fortify "statuses" and converts them to flash messages, with two separate arrays for regular flash messages, and ones that should be called with "now". I plan on adding it to this package later.

Helper Functions

There is 1 app level helper function to determine if there are any flash messages. This is useful if you have wrapped the call to the component with a div and it is creating spacing issues.

There are also 9 FlashMessages helpers available for use within the resources/views/vendor/flashmessages/components/message.blade.php file. You can see an example of most of these inside this blade file.

• isDismissable() - (bool) Determine if the flash message is dismissable.
• getClass() - Get the class name determined from typeToClassMap or the default if unknown.
• shouldShowIcon() - (bool) Determine if the icon should be shown.
• getIcon() - Get the icon determined from typeToIconMap or default if unknown.
• shouldShowTitle() - (bool) Determine if the title should be shown.
• hasTitle() - (bool) Determine if the flash message has a title.
• getTitle() - Get the title.
• hasMessage() - Determine if the flash message has a message (it should, but added just in case).
• getMessage() - Get the message.

Using HTML inside the message

You can pass HTML to the message if you need to.

Here is how you can pass a link in the message:

Note: alert-link is a Bootstrap class that makes the link color match the type/color of the alert. It isn't necessary if you aren't using Bootstrap. If you use Bootstrap and create your own custom types, you may want to also create the CSS for these as well.

Creating a new type

Creating a new type is very easy.

Add your icon's HTML to the typeToIconMap array in config/flashmessages.php:

For FontAwesome, I like to use the fa-fw class. This makes the icons all have the same width and it looks better overall. Especially when you show multiple messages on the screen.

Then add your class to the typeToClassMap array, also in config/flashmessages.php:

Note: If you are using Bootstrap, the class will be added to the alert prefix as alert-custom-class

Don't forget to create the CSS for your custom class:

Add your hover/active/visited effects if you want. You may be using mix or SASS instead of CSS. Do it properly and not a custom hack by throwing a style tag in the layout... Don't forget to run npm run dev if you need to, to re-compile the CSS you just added.

Individual Message Custom Configuration

The addFlashMessage() method supports a 3rd argument, a $config array. Most of the available options can be passed to the individual message's config array. However, you can not pass message, typeToIconMap, or typeToClassMap.

Example:

How to see the messages to modify the view files?

In order to edit the container or the message view files, you probably will need to be able to see at least 1 flash message so you can test it.

Create a route:

Change Controller to an appropriate controller. Any one will do, but probably whichever one is your main controller that renders your dashboard.

Add the test function to that controller:

This was a package I had from Laravel 8 that I quickly put back together for a Laravel 10 project. It is working on Laravel 10 just fine. I will update the docs and screenshots in the near future.

If you are good at writing docs, feel free to clean this mess of a doc up :)
