First of all make sure all the relations between your models are correctly formed. Considering the models you have shared these should be the relations you have to make:
- A
Product belongs to a Category.
- A
Category has many FeatureCategory.
- A
FeatureCategory has many Feature.
- A
Feature has many FeatureItem.
- A
Product has many FeatureItemProduct.
Controller Logic:
In your controller, when you're handling the creation of a product, retrieve the necessary data to pass to the view. For example:
public function create()
{
$categories = Category::all();
// Load other necessary data like features, feature categories, etc.
return view('products.create', compact('categories', 'otherData'));
}
View
Then inside your view where you are supposed to handle creation you might need some javascript and AJAX call to fetch data related to category like this:
<!-- Your form code -->
<div class="form-group">
<label for="category">Category</label>
<select id="category" name="category_id">
@foreach($categories as $category)
<option value="{{ $category->id }}">{{ $category->name }}</option>
@endforeach
</select>
</div>
<!-- Add divs/spans to hold dynamic feature and feature item fields -->
<script>
$(document).ready(function () {
$('#category').on('change', function () {
var categoryId = $(this).val();
// Make an AJAX request to fetch features and feature items based on the selected category
$.ajax({
url: '/get-features/' + categoryId,
type: 'GET',
success: function (data) {
// Update the UI with the retrieved data (e.g., add input fields dynamically)
// Use jQuery or vanilla JavaScript to manipulate the DOM
},
error: function () {
// Handle errors
}
});
});
});
</script>
AJAX Call
Define a route in web.php
Route::get('/get-features/{category}', 'ProductController@getFeatures');
Now in your ProductController:
public function getFeatures(Category $category)
{
// Retrieve features and feature items based on the selected category
$features = $category->features()->with('featureItems')->get();
return response()->json($features);
}
Adjust this based on your specific requirement.
Store
Finally store the created data into database
public function store(Request $request)
{
// Validate and store product data
// Attach features and feature items to the product
}
This is not an actual implementation of your use case and might not work directly without modification. This solution is just to provide you with the basic idea of actual implementation.
