Laravel 8 Create Custom Helper Functions Tutorial

This article is focused on laravel 8 custom helper functions. we will help you to give example of laravel 8 custom helpers. you can see laravel 8 create custom helper file.

This article goes in detailed on how to create custom helper function in laravel 8.

we know laravel 8 also provide helper function for array, url, route, path etc. But not all function provided that we require. maybe some basic helper function like date format in our project. it is many time require. so i think it's better we create our helper function use everywhere same code.

So let's create helpers file in laravel 8 by using following steps.

Now if you want to add custom helper functions in your website or project directory then you have to follow just three step and use it.

Step 1: Create helpers.php File

In this step, you need to create app/helpers.php in your laravel project and put the following code in that file:

app/helpers.php

<?php
  
function changeDateFormate($date,$date_format){
    return \Carbon\Carbon::createFromFormat('Y-m-d', $date)->format($date_format);    
}
   
function productImagePath($image_name)
{
    return public_path('images/products/'.$image_name);
}

Step 2: Add File Path In composer.json File

In this step, you have to put path of helpers file,so basically open composer.json file and put following code in that file:

composer.json

...
  
"autoload": {
    "psr-4": {
        "App\\": "app/",
        "Database\\Factories\\": "database/factories/",
        "Database\\Seeders\\": "database/seeders/"
    },
    "files": [
        "app/helpers.php"
    ]
},
  
...

Step 3: Run Command

this is the last step, you should just run following command:

composer dump-autoload

Ok, now at last you can use your custom helper functions like changeDateFormate() and productImagePath(), i am going to give you example how to use custom helper functions:

Use In Route:

Route::get('helper', function(){
    $imageName = 'example.png';
    $fullpath = productImagePath($imageName);
  
    dd($fullpath);
});
  
Route::get('helper2', function(){
    $newDateFormat = changeDateFormate(date('Y-m-d'),'m/d/Y');
  
    dd($newDateFormat);
});

Output:

"/var/www/me/laravel8/blog/public/images/products/example.png"

"09/14/2020"

Use In Blade File:

$imageName = 'example.png';
$fullpath = productImagePath($imageName);
print_r($fullpath);

{{ changeDateFormate(date('Y-m-d'),'m/d/Y')  }}

I hope it can help you...
