Understanding the Issue: Laravel Blade Foreach Limiting to 10 Items

If you've recently encountered a frustrating situation in Laravel where your Blade template's foreach loop displays only 10 candidates instead of the 12 you fetched from your database, you're not alone. This issue is often related to how the data is being retrieved and displayed in your application. Let’s delve into this problem and explore an effective solution.

Problem Breakdown

You have successfully loaded 12 candidate records based on a specific vacancy_id using the following code:

Despite count($candidates) confirming that you have indeed retrieved 12 items, the $sum variable calculated inside your foreach loop indicates that only 10 items are being processed, as shown below:

Possible Causes

Default Pagination: Laravel may be applying a default pagination to your collection, inadvertently limiting the number of items shown.

Database Query Constraints: There could be additional database constraints that return only a subset of items.

Solution: Implementing Pagination Correctly

To resolve this issue and effectively handle collections, particularly those intended for display on your Blade views, leveraging Laravel's built-in pagination feature is your best course of action.

Step-by-Step Solution

Modify Your Query

Instead of retrieving all candidates into a collection, employ the paginate method to manage the number of records displayed per page. Here's how you can achieve this:

This adjustment tells Laravel to load candidates associated with the provided vacancy ID, but to only display 10 of them at a time.

Update Your Blade View

In your Blade template, ensure that the pagination links are rendered so users can navigate through and view additional items if necessary:

Benefits of Using Pagination

User Experience: By paginating your results, you enhance the user experience as users can easily navigate through large datasets without overwhelming them.

Performance: Pagination improves performance by loading only a subset of records at any given time, making the application faster and more responsive.

Conclusion

If you're facing the issue of your Laravel Blade foreach loop only displaying a limited number of items, the solution lies in implementing pagination using Laravel's capabilities. This not only resolves the immediate problem but also provides a framework to manage larger datasets efficiently and user-friendly.

If your candidates don't display as expected after implementing these changes, double-check that your database contains the records you anticipate.

By following these steps, you will be able to print the full range of candidates, ensuring that your application works as it was intended.
