php - Form with enctype return null file in request

Solution:

The core issue here is thatvalue="{{ $product-> product_image }}" is not valid.<input type="file"> doesn't support that, as the image needs to be directly uploaded from the User's machine, and unless a file is selected and uploaded,$request->file('image') will benull.

To handle this cleaner, use some conditional logic in the Controller:

First, upload the image and set a reference to the file:

$profileImage = null;
if ($image = $request->file('image')) {
  $destinationPath = 'storage/img/tech/';
  $profileImage = $image->getClientOriginalName();
  $image->move($destinationPath, $profileImage);
}
Copy code

Next, set the$product->product_image based on the value of$profileImage:

$product = Product::find($id);
...
if ($profileImage)
  $product->product_image = $profileImage;
}
Copy code

Aternary ornull-coalesce statement can be used, but it'll look a bit weird:

$product->product_image = $profileImage ? $profileImage : $product->product_image;
// OR
$product->product_image = $profileImage ?? $product->product_image;
Copy code

Both of these cases will set$product->product_image to$profileImage, or the existing value of$product->profile_image if nothing is provided (that will be an existing image ornull)
