I am unable to fetch data using whereIn eloquent condition in laravel but same I can fetch all data without condition. how can I resolve this?
public function getOrders()
{
$customerNumberArr = Session::get('sales_customer');
$orderFormList = OrderForm::whereIn("CUSTOMER_NUMBER", $customerNumberArr)
->orderBy('id', 'desc')
->paginate(Config::get('common.per_page'));
return View::make('orderForms')->with('orderFormList',$orderFormList );
}

Im using Laravel 7 and to get an array like this Array image spect result
And im working with Eloquent. This is my code for that array
**return EvaluateTeacherQuestion::with('evaluate_teacher_possibles_answers')->get();**
And this is my function evaluate_teacher_possibles_answers to make the relationship
public function evaluate_teacher_possibles_answers()
{
return $this->hasMany(EvaluateTeacherPossibilites::class)->withCount('evaluate_teacher_answers')->with('evaluate_teacher_answers');
}
And to get the third condition use this
public function evaluate_teacher_answers()
{
return $this->hasMany(EvaluateTeacherAnswer::class, 'evaluate_teacher_possible_id');
}
The problem is in the table evaluate_teacher_answers, I need get only this that if a condition (teacher_id = $teacher) is right.
When you add the whereHas condition a subquery is added.
Eg:
EvaluateTeacherQuestion::with('evaluate_teacher_possibles_answers')->whereHas('evaluate_teacher_possibles_answers',function($query){
$query->where('column','operation','value');
})->get();
With this way, will included relation in model and will execute conditions on closure from related model
Try this way:
remove with('evaluate_teacher_answers') from evaluate_teacher_possibles_answers relation:
public function evaluate_teacher_possibles_answers()
{
return $this->hasMany(EvaluateTeacherPossibilities::class)->withCount('evaluate_teacher_answers')->;
}
then load that relation with your condition:
$value = EvaluateTeacherQuestion::with(['evaluate_teacher_possibles_answers'=>function($query)use($teacher_id)
{
$query->with(['evaluate_teacher_answers'=>function($query)use($teacher_id){
$query = $query->where('evaluate_teacher_answers.teacher_id',$teacher_id);
}]);
}])->get();
I am trying to get all the results where the user's status is teacher (which is a field in my table).
When I tried to use pagination, it runs into an error.
Here is my code in the controller where I'm fetching the results:
public function index()
{
$status = User::where('status', '=', 'teacher')->get();
return view('Profile.alluser')->with('status', $status)->paginate(3);
}
*note laravel version is 5.8
You need to paginate a Query, while you are trying to paginate a view, please try the code below:
public function index()
{
$status = User::where('status', '=', 'teacher')->paginate(3);
return view('Profile.alluser')->with('status', $status);
}
how to retrieve multiple rows from table with where condition using laravel 5.8
I tried with joins but i am not getting data. below provided code is not working in my instance.
I am able to get first row but i am looking for multiple rows.
public function show($id)
{
$event = Event::find($id);
$speaker = Speaker::where('event_id', '=', $id)->get();
return view('events-show')->with('event', $event)->with('speaker', $speaker);
}
I want to retrieve two tables data using laravel 5.8 and display in view page.
try this
$speaker=Speaker::join('events','events.id','speakers.event_id')->where('events.id', '=', $id)->get();
return view('events-show')->with('speaker', $speaker);
I have got three tables Kudos, Kudoscategories, and specialpost. I need to get the data from those tables and check the post id using a where condition.
I have attached the database table screenshot here
I already tried this, but it's not getting any result.
$results = DB::table('kudos')
->select('kudos.description','kudoscategory.catname','kudoscategory.image','kudos.spid')
->join('kudoscategory', 'kudoscategory.id', '=', 'kudos.categoryid')
->where('kudos.spid', '=', $post_id)
->first();
return $results;
What I need to do is get the results using below where condition newsfeed_special_posts.main_post_id = kudos.spid
You must add another join with newsfeed_special_posts.
The query will be like,
$results = DB::table('kudos')
->select('kudos.description','kudoscategory.catname','kudoscategory.image','kudos.spid')
->join('kudoscategory', 'kudoscategory.id', '=', 'kudos.categoryid')
->join('newsfeed_special_posts', 'newsfeed_special_posts.main_post_id', '=', 'kudos.spid')
->where('kudos.spid', '=', $post_id)
->first();
return $results;
Though this is not a good practice for laravel. using laravel eloquent relationships will be more efficient for these results.
https://laravel.com/docs/5.8/eloquent-relationships
you can still do it this way. still efficient to avoid sql injection since you are getting all the record from the 3 tables. seeing your table above, its not properly normalised. anywaye try this.
$results = DB::table('kudos')
->leftjoin('kudoscategory', 'kudoscategory.id', '=', 'kudos.categoryid')
->leftjoin('newsfeed_special_posts', 'newsfeed_special_posts.id', '=', 'kudos.spid')
->where('kudos.spid', '=', $post_id)
->first();
return $results;
you can try this code
at first, create model Kudos,KudosCategory,NewsfeedSpecialPosts
Kudos Model
public function kudoscategory_dta()
{
return $this->belongsTo('App\Model\KudosCategory','categoryid');
}
public function newsfeed_special_posts_dta()
{
return $this->belongsTo('App\Model\NewsfeedSpecialPosts','spid','main_post_id ');
}
controller
Kudos::with('kudoscategory_dta','newsfeed_special_posts_dta')->first();
I am building an api in laravel 5.3 using eloquent if I use /api/location/event_name/event_status then I am getting results.
But when I use /api/location/event_name or /api/location/ nothing comes.
How to write the query so that all my link show result?
class events_api extends Controller
{
public function events($location = "",$event_name="",$event_status="")
{
$events = DB::table('event_table')
->join('event_details', 'event_table.event_id', '=', 'event_details.event_id')
->join('venue', 'event_details.venue_id', '=', 'venue.venue_id')
->where('venue.venue_city','=',$location)
->where('event_table.event_name','=','$event_name')
->where('event_table.event_status','=','$event_status')
->where('event_table.event_post_status','=','publish')
->select('event_table.event_title','event_details.event_start_ts','event_details.event_views','venue.venue_name','venue.venue_city','venue.venue_location')
->get();
echo $events;
}
}``
If you would like to make a subQuery try using toSql method:
class events_api extends Controller
{
public function events($location = "",$event_name="",$event_status="")
{
$subQuery = DB::table('event_table')
->join('event_details', 'event_table.event_id', '=', 'event_details.event_id')
->join('venue', 'event_details.venue_id', '=', 'venue.venue_id')
->where('venue.venue_city','=',$location)
->where('event_table.event_name','=','$event_name')
->where('event_table.event_status','=','$event_status')
->where('event_table.event_post_status','=','publish')
->select('event_table.event_title','event_details.event_start_ts','event_details.event_views','venue.venue_name','venue.venue_city','venue.venue_location');
DB::table(DB::raw("{$subQuery->toSql()} as main_query"))
->mergeBindings($subQuery->getBindings())
// build your query here
->get()
}
}
You'll also need to mergeBindings if you use any bindings in subquery
