Laravel 8 Create Custom Helper Functions

Hello Dev.

This web article is focused on laravel 8 custom helper function. we are able to help you to present instance of laravel 8 custom helpers. you can see laravel 8 create custom helper file.

This web article is detailed in a way to create custom helper function in laravel 8.

we recognise laravel 8 also offer helper function for array, url, route, path and many others. however not all function provided that we require. perhaps

some basic helper function like date format in our project. it's many time require. so i assume it is better we create our helper function use everywhere same code.

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.

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


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"
"08/15/2020"

Use In Blade File

$imageName = 'example.png';
$fullpath = productImagePath($imageName);
print_r($fullpath);
{{ changeDateFormate(date('Y-m-d'),'m/d/Y')  }}
