Laravel 5.4 Multiple upload and Inserting data - laravel

Question

Hello everyone and thank you in advance, first of all sorry if my code is so confused I am still learning ^^.
I am trying to make a product with different attribute plus 3 different images(making the product gallery) and a feature image,
I have succeed to create the attributes and feature image.
The problem is with the 3 image for the gallery I cant store (neither in DB or image folder)
I have Two tables (product and productgallery) the relation between them is hasMany (I am using Laravel 5.4)
This the error I got after run the code
SQLSTATE[HY000]: General error: 1364 Field 'product_id' doesn't have a default value (SQL: insert into `product_galleries` (`updated_at`, `created_at`) values (2017-05-13 20:58:20, 2017-05-13 20:58:20))
(sorry for my English which for sure will make it harder to understand my question)
ProductController
public function store(UploadRequest $request)
{
$product = new Product();
$product->product_name = $request->product_name;
$product->product_description = $request->product_description;
if($request->hasFile('product_preview')) {
$file = Input::file('product_preview');
$filename = time(). '-' .$file->getClientOriginalName();
$product->product_preview = $filename;
$file->move(public_path().'/images/product-feature', $filename);
}
$product->category_id = $request->category_id;
$product->color_id = $request->color_id;
$product->size_id = $request->size_id;
$product->material_id = $request->material_id;
// $product->fantasia_id = $request->fantasia_id;
$productgallery = new ProductGallery();
if($request->hasFile('fileToUpload[]')) {
$files = Input::file('fileToUpload[]');
foreach ($request->$files as $photo) {
$filename = time(). '-' .$photo->getClientOriginalName();
$productgallery->product_images = $filename;
$photo->move(public_path().'/images/product-gallery', $filename);
$productgallery->product_id = 1;
}
}
$product->save();
$productgallery->save();
return $this->create()->with('success', 'Uploaded Successfully');
}
Upload request (FormRequest)
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class UploadRequest extends FormRequest
{
public function authorize()
{
return true;
}
public function rules()
{
$rules = [
'product_name' => 'required|max:120',
'category_id' => 'required|integer',
'product_preview' => 'required|image|mimes:jpeg,png,jpg,gif,svg',
];
$fileToUpload = count($this->input('fileToUpload'));
foreach(range(0, $fileToUpload) as $index) {
$rules['fileToUpload.' . $index] = 'image|mimes:jpeg,bmp,png|max:2000';
}
return $rules;
}
}
the view for the form
#extends('layouts.backend-master')
#section('styles')
<link rel="stylesheet" href="">

#section('content')
#if (count($errors) > 0)
<div class="alert alert-danger">

<ul>
#foreach ($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach

Answer 1

You'll need to look at Laravel relationships API documentation. Here's a link to read more about it Laravel 5.4 Eloquent Relationships
Quick tip to fix that
You should add a foreign key in your database/migration file
For a migration you can simply add
$table->foreign('product_id')->references('id')->on('products');
And add this method to your Product model
public function productgallery(){
return $this->hasMany(Productgallery::class);
}
and this to your Productgallery model
public function product(){
return $this->belongsTo(Product::class);
}
Note: You'll still need to populate the product_id field within your request
Package solution
I'd recommend you use a 3rd party package for that matter, as it will be less work, cleaner and more solid to use.
You can look more into spatie's medialibrary for Laravel

Answer 2

I think this is what you want.
This will create a new Product and create a new ProductGallery for each image passed in $request->file('fileToUpload[]'):
$product = new Product();
$product->product_name = $request->product_name;
$product->product_description = $request->product_description;
if($request->hasFile('product_preview')) {
$file = Input::file('product_preview');
$filename = time(). '-' .$file->getClientOriginalName();
$product->product_preview = $filename;
$file->move(public_path().'/images/product-feature', $filename);
}
$product->category_id = $request->category_id;
$product->color_id = $request->color_id;
$product->size_id = $request->size_id;
$product->material_id = $request->material_id;
// $product->fantasia_id = $request->fantasia_id;
// First save the product (so that you have it's ID)
$product->save();
// Then create galleries
if($request->hasFile('fileToUpload[]')) {
$files = Input::file('fileToUpload[]');
foreach ($files as $photo) {
$productgallery = new ProductGallery();
$filename = time(). '-' .$photo->getClientOriginalName();
$productgallery->product_images = $filename;
$photo->move(public_path().'/images/product-gallery', $filename);
$productgallery->product_id = $product->id; // Save it to the newly created product
$productgallery->save();
}
}
return $this->create()->with('success', 'Uploaded Successfully');
