laravel 7 - add new images on existing tables - php

Question

I was successful uploading multiple images while inserting a new record. I used two models Car and caralbum and made a join. However, I was trying to create an option to add more images on current list but failed to do so. my codes are-
controller to add new record with multiple images
$car = new Car;
.......
.......
$car->save();
if (count($request->car_image) > 0) {
foreach ($request->car_image as $image) {
........
........
Image::make($image)->save($location);
$caralbum = new caralbum;
$caralbum->car_id = $car->id;
$caralbum->image_name = $image_name;
$caralbum->image_location = $location;
$caralbum->save();
}
}
controller to add additional images
$car = Car::find($id);
if (count($request->car_image) > 0) {
foreach ($request->car_image as $image) {
....
....
Image::make($image)->save($location);
$caralbum = new caralbum;
$caralbum->car_id = $car->id;
$caralbum->image_name = $image_name;
$caralbum->image_location = $location;
$caralbum->save();
blade to add new record with multiple images
<input type="file" name="car_image[]" multiple>
blade to add additional images
<input type="file" name="car_image[]" multiple>
<a class="btn btn-success" href="{{ url('car_store_images/'.$cars->id) }}">
Add Images
</a>

Answer 1

I have found one problem. on the index blade where I am displaying the images the image class was not named as array. After adding [] after it, it is working now.
#foreach ($cars->join_caralbum as $image)
<div class="card" >
<img class="card-img-top" name="car_image[]" src="{{asset($image->image_location)}}" style ="height:90px; width:120px;" >
<a class="btn btn-danger" href="{{ url('car_destroy_image/'.$image->id) }}"
onclick="return confirm('Are you sure you want to delete all images for this car?')"><i class="fas fa-trash fa-xs"></i></a>
</div>
#endforeach
