Hi Guys,

Today, In this example, I would like to share with you how to create a custom helper example in laravel you can easily utilize add helper functions in laravel 8 application.

So, mainly you have to write repeated code in your laravel project so I think it's better we create our helper function use everywhere same code.

Here, I will give you a full example of laravel 8 create custom helper functions so follow my below steps.

Step 1: Download Laravel

Let us begin the tutorial by installing a new laravel application. if you have already created the project, then skip following step.

composer create-project laravel/laravel example-app
Step 2: Create helpers.php File

First of all we need to integrate app/helpers.php in your laravel project put below following code.

Path : app/helpers.php 
<?php

/**
* Write Your Code..
*
* @return string
*/  
function changeDateFormate($date,$date_format){
    return \Carbon\Carbon::createFromFormat('Y-m-d', $date)->format($date_format);    
}

/**
* Write Your Code..
*
* @return string
*/  
function thumbImagePath($image_name)
{
    return public_path('images/blogs/'.$image_name);
}
Step 3: Add File Path In composer.json File:

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

Path : composer.json 
...

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

In this last step you shoud required following command.

composer dump-autoload
Create Route

Now in this step we will use this custom helper function changeDateFormate() and thumbImagePath() in our web.php file.

Path : routes/web.php 

Route::get('helper', function(){
    $imageName = 'mywebtuts.png';
    $fullpath = thumbImagePath($imageName);
  
    dd($fullpath);
});
  
Route::get('helper2', function(){
    $newDateFormat = changeDateFormate(date('Y-m-d'),'m/d/Y');
  
    dd($newDateFormat);
});
Output 
"/var/www/html/blog/public/images/blogs/mywebtuts.png"

"10/09/2021"

So, you can use this helper function in your laravel blade file.

$imageName = 'mywebtuts.png';
$fullpath = thumbImagePath($imageName);
print_r($fullpath);

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

It will help you...
