I have some helper classes in app/Helpers
. How do I load these classes using a service provider
to use them in blade templates?
e.g. If I have a class CustomHelper
that contains a method fooBar()
:
<?php
nampespace App\Helpers;
class CustomHelper
{
static function fooBar()
{
return 'it works!';
}
}
I want to be able to do something like this in my blade templates:
{{ fooBar() }}
instead of doing this:
{{ \App\Helpers\CustomHelper::fooBar() }}
P.S: @andrew-brown's answer in Best practices for custom helpers on Laravel 5 deals with non-class files. It would be nice to have a class based solution so that the helper functions can be organized among classes.
I don't think it's possible to use only function when you have code in your classes. Well, you could try with extending Blade but it's too much.
What you should do is creating one extra file, for example app\Helpers\helpers.php
and in your composer.json file put:
"autoload": {
"classmap": [
"database"
],
"psr-4": {
"App\\": "app/"
},
"files": ["app/Helpers/helpers.php"] // <- this line was added
},
create app/Helpers/helpers.php
file and run
composer dump-autoload
Now in your app/Helpers/helpers.php
file you could add those custom functions for example like this:
if (! function_exists('fooBar')) {
function fooBar()
{
return \App\Helpers\CustomHelper::fooBar();
}
}
so you define global functions but in fact all of them might use specific public methods from some classes.
By the way this is exactly what Laravel does for its own helpers for example:
if (! function_exists('array_add')) {
function array_add($array, $key, $value)
{
return Arr::add($array, $key, $value);
}
}
as you see array_add
is only shorter (or maybe less verbose) way of writing Arr::add
