Managing Course Admissions in Laravel 8

Managing relations between different tables is a common requirement in web application development. In Laravel, you may often face the challenge of displaying information based on various conditions, particularly when dealing with relationships between tables like courses and admissions.

In this post, we will tackle a specific problem: showing whether a user has been admitted to a course they have purchased, or if they need to purchase the course. This guide will guide you through the necessary steps to accomplish this using Laravel 8's capabilities.

Problem Overview

You have two tables: courses and admissions. Your objective is to show a custom message depending on whether a user has purchased and been admitted to a course.

Current Implementation Issues

In your current implementation, you are fetching only a single record of admission per user, which leads to the following limitations:

Only one course is shown as "Admitted," regardless of how many courses the user has purchased.

The status of multiple courses cannot be displayed correctly.

To fix this issue, we need to modify our approach.

Solution Breakdown

Step 1: Fetch All Admissions

First, instead of fetching just the first admission record, you should retrieve all admission records for the currently authenticated user. This will allow you to handle multiple admissions per user.

Here’s how to do that:

Step 2: Update Blade View

Next, you'll need to loop over the list of courses and check against the list of admissions. Modify your Blade view as follows:

Summary

By following the steps outlined above, you can efficiently display the appropriate status for each course based on whether the user has purchased it or not.

Key Takeaways:

Always ensure you fetch all relevant records when dealing with relationships in Laravel.

Use Blade's loops and conditional statements effectively to handle multiple cases.

This approach will help you manage admissions more effectively for your users, ensuring they see the appropriate status for every course they’ve purchased.
