Where do I put Laravel 4 helper functions that can display flash messages?

Question

I\'ve written a simple display_messages() function that will search Session::get(\'errors\') for flash data and echo it to the screen.

Where do

Answer 1

As Usman suggested,

• create a file /application/libraries/demo.php
• define a class Demo() { inside it
• call the function like so: {{ Demo::display() }}

Works because libraries and models are autoloaded in start.php line 76. I believe that filenames must match Classnames (note capital).

<?php

class Demo {

    public static function display() {

        if( !$message = Session::get('errors'))
            $message = 'No Errors';

        echo "<pre>print_r($message)</pre>";

    }

}

Can't quite figure out why I had a problem using the classname Common, there may be a conflict (you could define a namespace if this were important)...

Answer 2

Create a folder helpers within your app folder and create a file application_helper.php. With such code:

// app/helpers/application_helper.php

function display_messages()
{
  exit('Yes');
}

Then open your composer.json file in root. autoload app/helpers/application_helper.php with composer files.

"autoload": {
....

    "files": [
        "app/helpers/application_helper.php"
    ]

Done, you can now call display_messages().

Some autoloaders may require you to run composer dump command for the first time.
