Laravel 8.1 IdGenerator - php

im a Laravel newbie and i try do generate Customerid for my Customer.Create.
My idea is to use they IdGenerator to generate id and then set the Id automatic in disabled input field on my creat.blade.php.
But im not shure is this idea right.
i write this in my web.php:
use Haruncpi\LaravelIdGenerator\IdGenerator;
Route::get('/customer/create', function(){
$config = ['table' => 'customers', 'length' => 10, 'prefix' => 'K-'];
$id = IdGenerator::generate($config);
return $id;
});
and this is the html snippen from my create.blade.php
<div class="col-auto">
<label class="sr-only" for="inlineFormInputGroup">Firma</label>
<div class="input-group mb-2">
<div class="input-group-prepend">
<div class="input-group-text"><i class="fas fa-building"></i></div>
</div>
<input type="text" class="form-control" id="inlineFormInputGroup" placeholder="{{ $id }}" disabled>
</div>
</div>
but i get everytime this erros message:
Exception table field type is bigint but prefix is string
Can you help me, is this the right way or do you have a better idea?
greetz Marcel

Change the field type of prefix to char and in your /database/migrations/your_table.php
change $table->bigInt('prefix') to $table->char('prefix') and then rerun your migrations Make sure you do not delete important data from your database please check the Laravel docs if you are not sure what you're doing.

update checkbox value in laravel 8 (blade/ controller )

I'm beginner in laravel and I want to update multiple checkboxes in database ..
when I click at update button automatically my inputs show old value also my permissions are checked by old value to update it ..
relation between user and permission is manytomany .. I have another table named userpermissions who has id_user and id_permission
this is my update form in ( edit.blade.php)
<form action="{{ url('users/'.$user->id) }}" method="POST">
#csrf
#method('PUT')
<div class="row">
<div class="col-md-6">
<div class="form-group">
<label>Name</label>
<input type="text" name="name" id="name" required class="form-control" value="{{ $user->name }}">
#error('name')
<ul class="alert"><li class="text-danger">{{ $message }}</li></ul>
#enderror
</div>
</div>
<div class="col-md-6">
<div class="form-group">
<label>Email</label>
<input type="email" name="email" id="email" required class="form-control" value="{{ $user->email }}">
</div>
</div>
<div class="col-md-12">
<div class="form-group">
#foreach($permissions as $permission)
<input type="checkbox" name="data[]" value="{{ $permission->id }}"
<?php if( in_array($permission->id, $user->userPermissions->pluck('permission_id')->toArray())){ echo 'checked="checked"'; } ?>/>
{{ $permission->name }}
#if($loop->iteration % 3 == 0 ) <br> #else #endif
#endforeach
</div>
</div>
</div>
<div class="text-right mt-4">
<button type="submit" class="btn btn-primary"> Add</button>
</div>
</form>
and this is my controller where I think have a problem with methods :
edit function
public function edit(User $user)
{
$permissions = Permission::get();
return view('users.edit', compact('user','permissions'));
}
update function :
public function update(UserRequest $request,User $user)
{
$user->update(
$request->only('name', 'email')
);
$user->userPermissions()->save($request->input('data'));
return redirect()->back()->with('status','user updated !');
}
and this is my functio store :
public function store(UserRequest $request)
{
$this->validate($request, [
'name' => 'required',
'email'=>'required|email',
'password' => 'required|confirmed|min:6',
]);
$user = User::create(
$request->only('name', 'email', 'password')
);
$user->userPermissions()->createMany($request->input('data'));
return redirect()->back()->with('status','Utilisateur ajouté !');
}
Thanks for advance !
$user->userPermissions()->save($request->input('data'));
One important thing to understand here, is that save() on relation doesn't remove old values from pivot table, it just add more values to it(no distinction check). You need something like refresh functionality. Look at attaching\detaching or sync, second one is more convenient.
In first case before saving permissions you can do this
// remove all old permissions
$user->userPermissions()->detach();
// update them with new one
$user->userPermissions()->attach($request->input('data'));
In second case, which is less verbose then first one you just need to pass and array of permissions to user object.
// this will do both things which we did before
$user->userPermissions()->sync($request->input('data'))
But i encourage you to read the docs and ask questions after ;)
Another thing which i saw and its not related to the current topic is
$user->userPermissions->pluck('permission_id')->toArray()
you are using lazy load inside of foreach loop which means that on each iteration of the loop you are making a query to the database(N + 1 problem). You can preload/eager load userPermissions instead of loading them on a fly by declaring with relation in your User model like this
class User extends Model
{
/**
* The relationships that should always be loaded.
*
* #var array
*/
protected $with = ['userPermissions'];
...
}
and then in your User object will have userPermissions property which you can compare to permissions.
Hope that you get main idea and info was useful for you!

How to solve the problem of getting unusual id in laravel

Here is my routes
Route::get('add-members/{id}','MemberController#create');
Route::post('save-member/{id}','MemberController#store');
This is my code to show the create form
public function create($id)
{
$team=Team::find($id);
$users = User::doesntHave('teams')->whereHas('roles', function($role) {
$role->where('name', 'member');
})->get();
return view('members.create',compact('users','team'));
}
An this is my code to store it
public function store(Request $request,$id)
{
$team=Team::find($id);
dd($request->id);
$team->users()->attach($request->id);
return redirect('home');
}
and this is my blade file
#extends('layouts.app')
#section('content')
<form action="{{url('save-member',$team->id)}}" method="post" accept-charset="utf-8">
#csrf
<div class="form-group row">
<label for="name" class="col-md-4 col-form-label text-md-right">{{ __('Select Member/s') }}</label>
<div class="col-md-6">
#foreach($users as $key => $user)
<input type="checkbox" name="id[]" value="{{$user->id}}">{{$user->email}}<br>
#endforeach
#error('member_id')
<span class="invalid-feedback" role="alert"><strong><font
color="red">{{ $message }}</font></strong></span>
#enderror
</div>
</div>
<button type="submit" class="btn btn-primary">Save</button>
</form>
#endsection
Now when i select none of the user and just click save button it will save the the user id as 1. After i am doing dd($request->id) it will show me the output 1. But in my form there is no users left or my form is empty.So where from 1 is coming. you can see this picture for clearify.
Please help me to solve this problems
You should be more specific with what data you are requesting from the Request:
$request->id; // could be an input named 'id' or a route parameter named 'id'
$request->input('id'); // is an input
$request->route('id'); // is a route parameter
You are running into a situation where you have a route parameter named id and potentially an input named id. Using the dynamic property of the Request, $request->id, will return the input id if it is there, if not it falls back to returning a route parameter named id.
Here is an article from the past that shows the issue with not being specific about what you are trying to get from the Request object:

how to update database using laravel controller? MethodNotAllowedHttpException No message error message

I'm trying to update my database using a form on my

Any help is greatly appreciated!
Based on Michael Czechowski I edited my answer to make this answer better, The main problem is inside your routes:
Route::put('/edit/{id}', 'PostsController#update');
You have to add the id inside your route parameters either. Your update() function needs two parameters, first the form parameters from the formular and second the $id of the edited log entry.
The second problem is , the form method field is 'patch' and your route method is 'put'.
The difference between 'patch' and 'put' is:
put: gets the data and update the row and makes a new row in the database from the data that you want to update.
patch: just updates the row and it does not make a new row.
so if you want to just update the old row change the route method to patch.
or if you really want to put the data, just change the put method field in your form.
simply by : {{method_field('PUT')}}
Remember, the form's and the route's methods must be same. If the form's method is put, the route method must be put; and vice-versa.
The main problem is inside your routes:
Route::put('/edit/{id}', 'PostsController#update');
You have to add the id inside your route parameters either. Your update() function needs two parameters, first the form parameters from the formular and second the $id of the edited log entry.
The second one is inside your HTML template:
<input type="hidden" name="_method" value="PUT" />
To hit the right route you have to add the corresponding method to your route Route::put('/edit/{id}', 'PostsController#update');.
A possible last problem
<form method="post" action="{{ action('PostsController#update', $post->id) }}">
I am not sure how your template works, but $id is possible not set inside your template. Maybe try to specify the ID depending on your post. Just to make it sure the ID comes from the shown post.
Further suggestions
Best practice is to use the symfony built-in FormBuilder. This would make it easier to target those special requests like PUT, PATCH, OPTIONS, DELETE etc.

How to show the old data in a form input in the Laravel

I write the form.blade.php like this:
<div class="form-group">
<label>Start at</label>
<div id="start_date" class="input-group date form_datetime col-md-4" data-date-format="yyyy-mm-dd hh:ii:ss">
<input class="form-control" name="start_at" size="16" type="text" value="{{ $activity->start_at }}">
<span class="input-group-addon"><span class="glyphicon glyphicon-remove"></span></span>
<span class="input-group-addon"><span class="glyphicon glyphicon-th"></span></span>
</div>
</div>
Both Create and Edit method use the view to display the form. In the Edit method, the $activity is used and everything is normal. But in the Create method, the $activity is null, so I have a error in {{ $activity->start_at }}.
I know I can use if(!empty($activity)) to prevent this error. but I do not want to use this anywhere.
What is the better way?
You could use this,
{{ $activity->start_at or '' }}
I also like to reuse code and use the same view to create or edit an object. What I do is to pass a brand new instance of the object to the create view. This way I have the object on its initial state including defaults (if any) and I am able to prefill those defaults (if any) on the displayed form. It gives me an additional benefit: if anything goes wrong with the validation at the server level the user doesn't lose any data, I just need to do something like this in the view:
<div class="form-group">
<label for="test_field" class="control-label">Fecha de firma</label>
<input type="text" value="{{ ( !empty($isabi) ? $isabi->fecha_firma : old('fecha_firma')) }}"
name="fecha_firma" id="isabi-fechafirma" class="form-control" placeholder="Este campo es obligatorio">
</div>
This is the create method with extra functionality removed for clarity (check if the user is authenticated, linking the created object with the company the user works for and other stuff):
public function create()
{
return view('isabis.create', [
"isabi" => new Isabi()
])->with($this->data);
}
I use $this->data for view configuration. Hope this helps.

Laravel 4 When i retrieve info from database into input text, 1 extra space is added

I am doing a form where the user can update his information. The form shows several inputs and the info retrieved from the database is displayed inside them.
I have noticed that, when the info is displayed, one extra space is added. For example, if i retrieve a date '1965-08-29', then in the form i notice that an extra space is added at the end: '1965-08-29 '.
This is happening in all inputs causing validation fails.
Here is a sample code about how i retrieve the data inside the controller:
$id_user=Auth::user()->id;
$usuario=User::find($id_user);
if(isset($usuario->nombre_pila)){$nombrepila=$usuario->nombre_pila;}else{$nombrepila='';}
if(isset($usuario->ap_paterno)){$ap_paterno=$usuario->ap_paterno;}else{$ap_paterno='';}
if(isset($usuario->ap_materno)){$ap_materno=$usuario->ap_materno;}else{$ap_materno='';}
Here is how i send these data to the view:
return View::make('profile.edit',array('id_user'=>$id_user, 'nombrepila'=>$nombrepila, 'ap_paterno'=>$ap_paterno,'ap_materno'=>$ap_materno));
Here are some examples of the inputs in the view:
<div class="form-group #if ($errors->has('nombre_pila')) has-error #endif"><!--Nombre de pila-->
<label for="nombre_pila" class="col-sm-2 control-label">Nombre(s) de pila:</label>
<div class="col-sm-6">
<input type="text" class="form-control" id="nombre_pila" name="nombre_pila" maxlength="45" value="#if(isset($nombrepila)){{$nombrepila}} #endif">
</div>
#if($errors->has('nombre_pila'))
{{$errors->first('nombre_pila')}}
#endif
</div><!-- ----------fin nombre de pila ------------ -->
<div class="form-group #if ($errors->has('ap_paterno')) has-error #endif"><!--apellido paterno-->
<label for="ap_paterno" class="col-sm-2 control-label">Apellido paterno:</label>
<div class="col-sm-6">
<input type="text" class="form-control" id="ap_paterno" name="ap_paterno" maxlength="45" value="#if(isset($ap_paterno)){{$ap_paterno}} #endif">
</div>
#if($errors->has('ap_paterno'))
{{$errors->first('ap_paterno')}}
#endif
</div><!-- ----------fin de apellido paterno ------------ -->
I am using bootstrap 3 forms (i don't know whether this has to do with the problem or not)
It could be that i should use something like the rtrim() function. But if someone out there could explain me why this is happening or what i am missing to do, i'll appreciate it.
You have a space before your #endifs. To fix that either do
value="#if(isset($ap_paterno)){{$ap_paterno}}#endif"
or (a bit nicer in my opinion)
value="{{ (isset($ap_paterno) ? $ap_paterno : '') }}"
