How to Create Custom Helper Functions in Laravel

Are you tired of repeating code and want to simplify your views in Laravel? 🤔 Custom helper functions may be just the solution you need! In this blog post, we'll explore how to create globally available helper functions in Laravel, using the example of a text formatting function called fooFormatText(). Let's dive in! 💪

The Problem: Repeating Code in Views

Imagine you have multiple views in your Laravel project, and they all require the same text formatting function fooFormatText(). One way to use this function in your views is by including it directly like this:

<p>Foo Formatted text: {{ fooFormatText($text) }}</p>

However, if you have many views where you need to use this function, this approach can lead to code duplication and make your views harder to maintain. 😫

The Solution: Custom Helper Functions

To avoid repeating code between views, we can define globally available helper functions in Laravel. By doing so, we can easily format text in our views without duplicating code. Here's how to create your custom helper function:

Step 1: Open the app/helpers.php File

Laravel provides a helpers.php file where you can define your custom helper functions. If you don't have this file, you can create it in the app directory.

Step 2: Define Your Helper Function

Inside the helpers.php file, define your fooFormatText() function. Here's an example implementation:

<?php

function fooFormatText($text)
{
    // Your text formatting logic here
    return strtoupper($text);
}

In this example, we're converting the input text to uppercase using the strtoupper() function. You can replace this with your desired formatting logic.

Step 3: Include the helpers.php File

The next step is to include the helpers.php file in your Laravel project, so the helper functions become globally available. Open the composer.json file located in the root directory of your project, and add the following code snippet to the autoload section:

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

Make sure to add a comma after the last item in the files array if it's not already the last item.

Step 4: Run composer dump-autoload

After updating the composer.json file, open your terminal and navigate to your project's root directory. Run the following command to update the autoload files:

composer dump-autoload

This command will regenerate the Composer's autoloader files and include your helpers.php file.

Step 5: Start Using Your Custom Helper Function

You're all set! Now you can use your fooFormatText() function anywhere in your Laravel project. For example, in your view, you can write:

<p>Foo Formatted text: {{ fooFormatText($text) }}</p>

This will apply the text formatting logic defined in your custom helper function.

Conclusion

Creating custom helper functions in Laravel allows you to avoid repetitive code in your views and keep them clean and maintainable. By following the steps outlined in this guide, you can define globally available helper functions and use them across your Laravel project.

So, go ahead and simplify your codebase with custom helper functions! Your future self (and your fellow developers) will thank you. 😄
