I have form in laravel framework, and i want to save the value of the user input in order to use it in other textbox at the same form.
This is my Controller code:
public function create(Request $request)
{
$clientnames = Customer::where('payeee' , $request->payeee)->get('client_name');
but $request->payee doesn't return the value input of the user in the textbox.
how can i do it?
thanks in advance.

I've got a Laravel project (actually a Laravel Nova project) that involves entering a lot of data. To save some time I'd like to pre-fill some of the fields in my form, based on the logged in user's last entry.
I can pre-fill fields via the $attributes variable on my model, called Product, like so:
protected $attributes = [
'category' => 'ABC'
];
And I can do this for more dynamic data in the constructor like so:
function __construct() {
$this->attributes['category'] = Str::random();
parent::__construct();
}
But I'm not quite sure how I'd go about this when I want to retrieve what the user entered last time. For example, I'd like to do this:
function __construct() {
$user = auth()->user()->id;
$last = Product::where('created_by', $user)->latest()->first();
$this->attributes['category'] = $last['category'] ?? null;
}
However that ends up in an infinite loop. Same if I call $this->where('created_by' ...
Is there a way I can set $attributes of a new Product based on the last Product created by the user?
Nova fields have resolveUsing method, so in your case if you want to populate Text field:
Text::make('Category')->resolveUsing(function () {
return optional(auth()->user()->products()->latest()->first())->category;
})
I found the solution in the Nova Defaultable package.
Once you add the necessary traits, you can just add ->defaultLast() to a resource field and it'll default to the last set value. This also works for relationships which is perfect for my use case.
I'm trying to show the data of the authenticated user from his relation with other tables but can't get it to work, and I'm pretty new to laravel.
the user table has a relation with level table thru level_id, and the level table has a morph relation with the languages table, I'm trying to show the language of the level of the current user
here is my user model relation
public function level()
{
return $this->belongsTo(Level::class, 'level_id');
}
and my level model
public function languages()
{
return $this->morphMany(Language::class, 'langable');
}
and in the language table, I need to get back the title of 0 or 1 like
languages['0']title.
here is my controller
public function profile()
{
$user= User::with('level')->with('offers')->get();
return view('pages.user.index',compact('user'));
}
and here is how I got the auth user
{!! auth()->user()->first_name . ' ' . auth()->user()->last_name !!}
I'm trying to get this to work
{{auth()->user()->level()->languages()->title['0']}}
but it shows me this
Try {{ $user->level->languages->title['0'] }} in your index.blade file since you are passing the $user var from your controller to it. Currently you are using the user from session.
i got the answer guys it goes like this
{{Auth::user()->level->languages[0]->title}}
that'd show the level of the current user
Okay, there are a few steps you need to get done
in your controller:
public function profile()
{
$user = Auth::user(); // gets the logged in user
return view('pages.user.profile', compact('user')); // return view with $user variable
}
in your user model add:
// appends the level data to the $user model
// so every time you retrieve a user, the level data is included and accessible
// after that you can use $user->level in your view file
protected $appends = [
'level'
];
in your level model add:
// appends the languages data to the $user model
// so every time you retrieve a level, the languages data is included and accessible
// after that you can use $level->languages in your view file
protected $appends = [
'languages'
];
NOTE: In Step 3 you are retrieving multiple languages for a level. Is that correct ?
usage in view
$user->level->languages[specificLanguage]->title // if level has multiple languages
$user->level->language->title // if level has one language
In my app i have a Posts and a Reacts table both are connected with relationship.
In App user can react to a post(like or dislike) and for retrieve this i'm using this function :
public function feed()
{
$posts=Post::with('user')
->with('reacts')
->withCount('comments')
->orderBy('created_at', 'DESC')
->get();
return response()->json(["posts" => $posts]);
}
the response is:
i want to add one more field in Posts Object for isUserLiked and if the current authenticated user liked the post then value will be true or false for him something like this:
i can add a additional field but how can i set the value dynamically for that
this is what i am doing in my Post Model:
protected $appends = ['isUserLiked'];
public function getIsUserLikedAttribute($id)
{
$react=React::where('user_id',auth()->user()->id)->where('post_id',$id)->exists();
return $react;
}
this is returning false because i don't know any way to pass the arguments(Post id).
is there any better way i can get the desired response? Thanks!
public function getIsUserLikedAttribute($id)
{
return React::where('user_id',auth()->user()->id)->where('post_id',$this->id)->exists();
}
In your user model:
public function reacts(){
return $this->hasMany(React::class);
}
public function scopeReactOnPost($query, $post_id){
return $this->reacts()->where(function($query) use ($post_id){
$query->where('post_id',$post_id);
});
}
and in your controller:
$user->reactOnPost($post_id)->first();
or
$user->reactOnPost($post_id)->get()->count();
Will let you know if user had any reaction on the specified post.
and for adding this to your json output you can artisan make a resource for your post model. Laravel Resources
I need to add orders to existing customers. From my customers.show view I use the following to visit the order form.
href="{{action('OrderController#create', $customer['id'])}}
The link of the page looks like:
/orders/create?2f10f8a0-30b9-11e8-8711-dd477b141226
I've been using the following route::get to no avail to be able to use this ID in my resource controller for Orders
Route::get('orders/create/{id}', 'OrderController#create');
Basically need to be able to to something along the lines of below to be able to show customer details while displaying the create order form as well but getting stuck on best way to pass the id through for the current customer
public function create(){
$customer = Customer::find($id)
return view('orders.create', compact('customer'));
}
With Laravel, you just need to add the parameters you specified in the route as function parameters, like below:
public function create($id){
$customer = Customer::find($id)
return view('orders.create', compact('customer'));
}
You are not passing the $id argument in the create function.
Change it to:
public function create( $id ){
$customer = Customer::find($id)
return view('orders.create', compact('customer'));
}
I have User that has many Posts.
Bellow the User edit form I want to show the related Posts grid.
The following function will bring the related posts.
How can I combine it above/inside/bellow the edit User form?
I know this function will work, just don't know how to combine it.
// user crud controller
public function getUserRlatedPosts($user_id)
{
$crud = new CrudPanel();
$crud->addClause('where', 'user_id', '=', $user_id);
$crud->setModel("post");
$crud->setEntityNameStrings("post","posts");
$crud->enableAjaxTable();
$this->data['crud'] = $crud;
$this->data['title'] = ucfirst($this->crud->entity_name_plural);
if (! $this->data['crud']->ajaxTable()) {
$this->data['entries'] = $this->data['crud']->getEntries();
}
return view('crud::list', $this->data);
}
In Backpack\CRUD 3.2.x you can use a custom view with the following methods:
$this->crud->setShowView('your-view');
$this->crud->setEditView('your-view');
$this->crud->setCreateView('your-view');
$this->crud->setListView('your-view');
$this->crud->setReorderView('your-view');
$this->crud->setRevisionsView('your-view');
$this->crud->setRevisionsTimelineView('your-view');
$this->crud->setDetailsRowView('your-view');
and specify the view in which you also include that form.
