How to Hide Empty Sections in Your Laravel 7 Blade Template with IF Conditions

When developing with Laravel, particularly utilizing the Blade templating engine, it is common to encounter situations where you want to hide certain sections of your view if there are no values to display. This practice leads to cleaner, more user-friendly interfaces. In this post, we will explore how to manage visibility effectively using Blade's conditional IF statements.

The Problem

You may have a Blade template that includes separate sections for displaying certain data (e.g., skills used in a project). However, if there are no relevant entries, you want these sections not to be displayed at all. Here's an example of how your Blade code might look if improperly set up to hide empty sections:

Common Issue

In the above code, if the variable $skillsused is empty or doesn't contain any entries with the specified condition, the section will needlessly appear blank, potentially creating confusion for users. Moreover, if you try to count a non-array variable using the count() function like this:

You may encounter an error indicating that the parameter must be an array or implement the Countable interface.

The Solution

To effectively manage visibility in your Blade template, you can use the filter method to check for conditions before rendering the section. Here’s how you can improve your code:

1. Using the filter Method

The filtering method allows you to remove unwanted data before counting. Here's how to implement it:

2. Utilizing PHP 7.4 and Above

If you are using PHP 7.4 or above, you can take advantage of arrow functions to simplify the inline callback syntax. Here’s the more concise version:

Benefits of This Approach

Cleaner UI: Only displays sections that have relevant data, improving user experience.

Avoiding Errors: Prevents potential errors related to counting non-countable objects.

Improved Readability: Using filters can lead to clearer and more maintainable code.

Conclusion

By implementing conditional visibility in your Laravel Blade templates, you can significantly enhance the user's experience while ensuring your application's interface remains clean and functional. Using the filter method achieves this with ease and allows your code to maintain clarity and purpose. With the examples provided, you're now equipped to manage empty sections gracefully and ensure that your application only displays relevant information. Happy coding!
