Laravel 9 Failing to update data in DB - php

Question

I am building a blog using Laravel 9 and my update method for some unknown reason fails to update
My code Samples
Model
class Anime extends Model
{
use HasFactory;
protected $table = 'anime';
protected $primaryKey = 'id';
protected $fillable = ['anime_title','user_id','blog_title','description','slug','anime_image_profile'];
public function blogInformation() {
return $this->hasMany(BlogInfo::class);
}
public function getRouteKeyName()
{
return 'slug';
}
// protected $hidden = 'id';
}
Controller
public function update(ValidateAnimeBlogRequest $request, $id)
{
$request->validated();
/*Update the details in the database by ID*/
$update_data = Anime::findOrFail($id);
$update_data = new Anime;
$update_data->anime_title = $request->input('anime_title');
$update_data->blog_title = $request->input('blog_title');
$update_data->user_id = auth()->user()->id;
$update_data->description = $request->input('description');
$update_data->slug = Str::slug($request->input('blog_title'));
/*Check if the user also wanted to update the image*/
if($request->hasFile('anime_image_profile')) {
$path_to_images = 'images/anime_image_profile/' . $update_data->anime_image_profile;
if(File::exists($path_to_images)) {
File::delete($path_to_images);
}
$new_file_name = '9anime' . '-' . time() . '-' . $request->name . '.' . $request->anime_image_profile->extension();
$request->anime_image_profile->move(public_path('images/anime_image_profile'), $new_file_name);
$update_data->anime_image_profile = $new_file_name;
}
if($update_data->update()) {
redirect('/');
}
dd('Error');
}
ValidateAnimeBlogRequest
public function rules()
{
return [
'anime_title' => 'required | min:2', new nameRegex,
'blog_title' => ['required','min:5', new nameRegex],
'description' => ['required','min:1000'],
'premiered' => ['required'],
'genre' => ['required', new nameRegex],
'licensors' => ['required', new nameRegex],
'studio' => ['required', new nameRegex],
'anime_image_profile' => 'required | mimes:jpeg,jpg,png | max:5408'
];
}
My blade file
<form enctype="multipart/form-data" autocomplete="off" action="/blog/{{$anime['id']}}" method="POST">
#method('PUT')
#csrf
I set up a custom check just in case
if($update_data->update()) {
redirect('/');
}
dd('Error');
The output on my webpage from this is "Error" // app\Http\Controllers\AnimeController.php:156
And when I dd($update_data) I see that the data has been updated yet it does not get sent to the database.
I tried replacing $update_data->update() with $update_data->save() but that now creates new data in the DB instead of updating the existing one

You can keep it as the save() method. Just update the lines above where you are creating a new Anime() instance to only be created if the record cannot be found via $id from the line above.
public function update(ValidateAnimeBlogRequest $request, $id)
{
$request->validated();
/*Update the details in the database by ID*/
$update_data = Anime::findOrFail($id);
if(!$update_data) {
$update_data = new Anime;
}
$update_data->anime_title = $request->input('anime_title');
$update_data->blog_title = $request->input('blog_title');
$update_data->user_id = auth()->user()->id;
$update_data->description = $request->input('description');
$update_data->slug = Str::slug($request->input('blog_title'));
/*Check if the user also wanted to update the image*/
if($request->hasFile('anime_image_profile')) {
$path_to_images = 'images/anime_image_profile/' . $update_data->anime_image_profile;
if(File::exists($path_to_images)) {
File::delete($path_to_images);
}
$new_file_name = '9anime' . '-' . time() . '-' . $request->name . '.' . $request->anime_image_profile->extension();
$request->anime_image_profile->move(public_path('images/anime_image_profile'), $new_file_name);
$update_data->anime_image_profile = $new_file_name;
}
if($update_data->save()) {
redirect('/');
}
dd('Error');
}
This will create a new instance only if a record is not found and won't give a new db record
