How to update a product in Laravel 5.8 - laravel

Question

I have a product that I want to edit. Please see the following code.
public function update(ProductRequest $request, Product $product)
{
$product->user_id = auth()->user()->id;
$product->title = $request->title;
$product->body = $request->body;
$product->price = $request->price;
if ($request->has('image')) {
$image = $request->file('image');
$filename = $image->getClientOriginalName();
$image->move(public_path('images/products'), $filename);
$product->image = $request->file('image')->getClientOriginalName();
}
$product->update();
$product->categories()->sync($request->category);
return redirect()->route('products.index');
}
product.blade.php
<form class="form-horizontal" action="{{ route('products.update', $product->id) }}" method="post" enctype="multipart/form-data">
{{ csrf_field() }}
{{ method_field('PATCH') }}
.
.
.
Everything changes except the image. I tried it, but, I did not succeed. What's the solution? I want to update the image in the database.
OK, I go to database now, I changed in image to picture, then I go my project, and I tested this again.
But it did not event for me.
I changed
public function update(ProductRequest $request, Product $product)
To
public function update(Request $request, Product $product)

To update a model, you should retrieve it, set any attributes you wish to update, and then call the save method. See the updates section in the documentation.
public function update(ProductRequest $request, Product $product)
{
$product->user_id = auth()->user()->id;
$product->title = $request->title;
$product->body = $request->body;
$product->price = $request->price;
if ($request->has('image')) {
$image = $request->file('image');
$filename = $image->getClientOriginalName();
$image->move(public_path('images/products'), $filename);
$product->image = $request->file('image')->getClientOriginalName();
}
$product->save();
$product->categories()->sync($request->category);
return redirect()->route('products.index');
}
Update 1
Assuming you have debugged the above and $request->file('image')->getClientOriginalName() is returning the expected value, it's possible that you are using field whitelisting on your model and haven't added the image field to the whitelist. Make sure that image is in the $fillable array on your model.
class Product extends Model
{
protected $fillable = [
'user_id',
'title',
'body',
'price',
...
'image'
];
Update 2
If $request->file('image') is returning null then that would suggest your form is not submitting the files. Ensure your <form> element has the enctype="multipart/form-data" attribute included in the tag.
Update 3
If your already including the required enctype="multipart/form-data" tags in the <form> element then I would suggest doing the following.
Place dd($request->all()); at the top of your update(ProductRequest $request, Product $product) method. Post the form and check the output.
If the file is not included in the output, change from using ProductRequest $request to the default Request $request (Illuminate\Http\Request) and try it again. There could be something in your ProductRequest class that is causing a problem.
As a small critique, you could improve your code in the following ways.
・Use hasFile() instead of has().
・Use $product-image = $filename instead of $product->image = $request->file('image')->getClientOriginalName();.
public function update(ProductRequest $request, Product $product)
{
$product->user_id = auth()->user()->id;
$product->title = $request->title;
$product->body = $request->body;
$product->price = $request->price;
if ($request->hasFile('image')) {
$image = $request->file('image');
$filename = $image->getClientOriginalName();
$image->move(public_path('images/products'), $filename);
$product->image = $filename;
}
$product->save();
$product->categories()->sync($request->category);
return redirect()->route('products.index');
}

Answer 2

make sure your has
enctype="multipart/form-data"
property
