I'm trying to get the total comments the user have..
Controller:
public function index()
{
$setting = Setting::findOrFail(1);
$comments = Comment::where('published', '=', '1')->get();
$users = User::all();
return view('page.index', compact('setting', 'comments', 'users'));
}
View:
#foreach($comments as $comment)
{{ count($users->where('user_id', '=', $comment->user_id)) }}
#endforeach
The problem is that it only returns 0 and i have 2 comments there.. even using the user id to instead of "$comment->user_id" it doesnt work. still display 0.
$users is a collection, not a query. Treat it as such:
#foreach ($comments as $comment)
{{ $users->where('user_id', $comment->user_id)->count() }}
#endforeach
The collection's where method does not take an operator.
From the wording in your question it seems you actually want it the other way around:
$comments = Comment::wherePublished(1)->get()->groupBy('user_id');
Then in your view:
#foreach ($users as $user)
{{ $comments->has($user->id) ? count($comments[$user->id]) : 0 }}
#endforeach
I'm late to answer your question and Joseph already showed you the problem but you may also do it differently. You can group comments using Collection::groupBy, for example:
$comments = Comment::all()->groupBy('user_id');
Then in your view you may try this:
#foreach($comments as $user => $userComments)
// count($userComments)
// Or
#foreach($userComments as $comment)
// {{ $comment->title }}
#endforeach
#endforeach
In the first loop (#foreach($comments as $user => $userComments)), the $user is the user_id and it's value would be all comments (an array) by this user but in group.

I'm using Laravel 5.6 and I have created two Models Question and User Model and these are linked to each other using one to many relation as:
Question Model
public function user() {
return $this->belongsTo('App\User');
}
User Model
public function questions() {
return $this->hasMany('App\Question');
}
And my controller code is:
public function index()
{
$user = User::all();
return view('home', compact('user'));
}
So, i'm trying to get question title and I have written this code in blade:
#foreach($user as $user)
{{ dd($user->questions->questions_title) }}
#endforeach
But getting error undefined index questions_title, but if only write this {{ dd($user->questions) }} it gave me all questions, so how to fix it.
I have also tried {{ dd($user->questions['questions_title']) }} but not fixed.
You'll want to loop over your questions relationship to see your question:
#foreach($user as $u)
#foreach($u->questions as $question)
{{ dd($question->questions_title) }}
#endforeach
#endforeach
Note: I changed $user to $u
In your controller, you are not eager loading your questions relationships. Change your code to the following:
public function index()
{
$user = User::with('questions')->get();
return view('home', compact('user'));
}
Using the with() method will load all specified relationship with the eloquent query. After this, you will need to loop through the questions collection using the ->each() collection method.
#foreach($users as $user)
#foreach($user->question as $question)
{{ $question->question_title }}
#endforeach
#endforeach
No need for two foreach loops we can simply use one like below:
#foreach ($user->questions as $question)
{{ dd($question->questions_title) }}
#endforeach
I'm trying to get all the users where a given method in User model meets. Please see my code below:
User.php
public function isPicker(){
return ($this->where('isPicker', 1)) ? true : false;
}
Now, I can use User::all();, but it returns all the users. What I want is to only return the users that meets the isPicker() method. What I'm trying to do in view is:
#foreach($users as $user)
#if($user->isPicker())
{{ $user->first_name }}
#endif
#endforeach
This is also working fine, but it is not that efficient to use. What if there's a lot of method to check? Any idea for this?
Just do:
$users = User::where('isPicker', 1)->get();
Or create a scope:
public function scopeIsPicker($query)
{
return $query->where('isPicker', 1);
}
// usage
$users = User::isPicker()->get();
Well you could change you code up a little to look like this.
#foreach($users->where('isPicker', 1)->all() as $user)
{{ $user->first_name }}
#endforeach
But this will only work if the users var is a collection.
Other wise just change you query on how your getting the users to something like this.
User::where('isPicker', 1)->get()
Instead of checking in model file, you can directly query in your controller try below code
if you want to display only isPicker=1 users.
Controller Code :
$users = User::where('isPicker', 1)->get();
Blade code :
#foreach($users as $user)
{{ $user->first_name }}
#endforeach
OR
if you want to display all users including isPicker 0&1.
Controller Code :
$users = User::all();
Blade code :
#foreach($users as $user)
#if($user->isPicker == 1)
{{ $user->first_name }}
#else
<p>Picker is 0</p>
#endif
#endforeach
Note : Remove your isPicker function from user model file because its unuse.
I have a problem I can not solve. I have a foreach that prints me an HTML every time it finds value in the database, and it all works.
However, I would like to avoid putting html in the controller.php file.
At the moment I did:
$html_console='';
if($article->id_game > '0'){
$prel_console = \DB::table('info_game')
->where('id_game', '=', $article->id_game)
->get();
foreach($prel_console as $name_console)
{
$name_console_game = \DB::table('console')
->where('id', '=', $name_console->id_console)
->first();
$html_console.='<span class="label">'. $name_console_game->abb_cat.'</span>' ;
}
}
While in the blade:
{!! $html_console !!}
I tried to do this in the blade:
#foreach ($prel_console as $name_console)
<span class="label margin-top-5 font-size-10">{{ $name_console_game->abb_cat }}</span>
#endforeach
If I put the foreach in the blade, how do I deal with the query "name_console_game"
If you have a one to many relation between info_game table which should have a InfoGame model and console table with Console model then your could do something like this:
controller:
public function someMethod()
{
// assuming that you already have an $article object
$infoGame = InfoGame::where('id_game', $article->id_game)->get();
return view('some.view', compact('infoGame'));
}
view location views/some/view/blade.php
#foreach($infoGame->console as $name_console_game)
<span>{{ $name_console_game->abb_cat }}</span>
#endforeach
I use Laravel with foreach in a blade.php
{{ $users = App\User::where('user_id', $post->user_id)->get() }}
and I got the result of this which show on the page
[{"user_id":"123","email":"123#com","password":"1234","first_name":"Tony"}]
But I want to get "Tony" only, how can I call?
{{ ($users = App\User::where('user_id', $post->user_id)->first())->first_name }}
Or better in sense of performance, if you select posts with user:
{{ $post->user->first_name }}
But it is better to prepare necessary data in controller.
get() returns an array, you should use first()
{{ ($users = App\User::where('user_id', $post->user_id)->first())->first_name }}
Since you said you are using foreach in blade. Try something like this
#foreach($user as $u)
{{$u->first_name}}
#endforeach
This will give you first_name for all users
I need to find out unique value. So I tried bellow code. It is through undefined variable error.
Controller:
$employee = Employee::all();
Return view ('page', compact('employee'));
Page view:
$uniqueEmpLoc = $employee->unique('location')->values()->list('location')->toArray();
#Foreach($uniqueEmpLoc as $empLoc)
{{ $empLoc }}
//this is select box used for search
#endforeach
//Display Entire data
#foreach($employee as #employee)
//Display all value
#endforeach
But I got an uniqueEmpLoc is undefined error. I'm using LARAVEL 5.1. Please help me to solve this problem.
There are some errors in your code:
I don't think compact(employee) would work. Shouldn't that suppose to be compact('employee') ?
In Blade, there is no need of putting curly braces at all. Remove them.
Try out the following:
$employees = Employee::unique('locations')->values()->list('location')->toArray();
return view('page', compact('employees'));
And then in your view:
#foreach($employees as $employee)
{{ $employee }}
#endforeach
Use this query in controller
$employees = Employee::distinct()->list('location')->toArray();
return view('page', compact('employees'));
In view
#foreach($employees as $employee)
{{ $employee }}
#endforeach
I agree with the other answers here, this code should be in the controller. You shouldn't be doing logic in the views.
In the controller do:
$uniqueEmpLoc = $employee->unique('location')->values()->list('location')->toArray();
$employee = Employee::all();
Return view ('page', compact('employee', 'uniqueEmpLoc'));
The reason your code isn't working is the line that defines $uniqueEmpLoc is interpreted by blade as text, not code.
If you really want to do that in the view, you need to wrap it in #php tags.
#php
$uniqueEmpLoc = $employee->unique('location')->values()->list('location')->toArray();
#endphp
#Foreach($uniqueEmpLoc as $empLoc)
{{ $empLoc }}
//this is select box used for search
#endforeach
