I am trying to read data from a local collections from my mongodb database. Name of database Intuit name of collection post.
Code inside PostController:
<?php
use Illuminate\Http\Request;
use App\Models\Post;
class PostController extends Controller{
public function home() {
$posts = Post::with(['user'])->get();
return view('home', ['posts' => $posts->toArray()]);
}}
Code inside Post:
class Post extends Model{
use HasFactory;
protected $fillable = [
'STATUS',
'DDC_CODE',
'TRADE_NAME',
'SCIENTIFIC_CODE',
'SCIENTIFIC_NAME',
'INGREDIENT_STRENGTH',
'DOSAGE_FORM_PACKAGE',
'ROUTE_OF_ADMIN',
'PACKAGE_PRICE',
'GRANULAR_UNIT',
'MANUFACTURER',
'REGISTERED_OWNER',
'UPDATED_DATE',
'SOURCE'
];}
All of the above are the titles of the columns in the table.
Next home.blade.php:
<!DOCTPE html>
<html>
<head>
<title>View Records</title>
</head>
<body>
<table border = "1">
<tr>
<td>Id</td>
<td>STATUS</td>
<td>DDC_CODE</td>
<td>TRADE_NAME</td>
<td>SCIENTIFIC_CODE</td>
<td>SCIENTIFIC_NAME</td>
<td>SCIENTIFIC_CODE</td>
<td>INGREDIENT_STRENGTH</td>
<td>DOSAGE_FORM_PACKAGE</td>
<td>ROUTE_OF_ADMIN</td>
<td>PACKAGE_PRICE</td>
<td>GRANULAR_UNIT</td>
<td>MANUFACTURER</td>
<td>UPDATED_DATE</td>
<td>SOURCE</td>
</tr>
#foreach ($posts as $post)
<tr>
<td>{{ $post->_id }}</td>
<td>{{ $post->STATUS }}</td>
<td>{{ $post->DDC_CODE }}</td>
<td>{{ $post->TRADE_NAME }}</td>
<td>{{ $post->SCIENTIFIC_CODE }}</td>
<td>{{ $post->SCIENTIFIC_NAME }}</td>
<td>{{ $post->INGREDIENT_STRENGTH }}</td>
<td>{{ $post->DOSAGE_FORM_PACKAGE }}</td>
<td>{{ $post->ROUTE_OF_ADMIN }}</td>
<td>{{ $post->PACKAGE_PRICE }}</td>
<td>{{ $post->GRANULAR_UNIT }}</td>
<td>{{ $post->MANUFACTURER }}</td>
<td>{{ $post->REGISTERED_OWNER }}</td>
<td>{{ $post->UPDATED_DATE }}</td>
<td>{{ $post->SOURCE }}</td>
</tr>
#endforeach
</table>
</body>
</html>
The route handler is as follows
Route::get('view','App\Http\Controllers\PostController#home');
all of this seems to be fine but when I load up the application I see nothing but the column titles not sure what I am missing, I believe it is not working because the query in PostController is incorrect and need to change it as it is taken from another projec. Any and all help and suggestions are welcome.
Instead of
Post::with(['user'])->get();
use
Post::with(['user'])->all();
subject to user relationship is properly defined in your Post model
You are sending data as array, But you are trying to get them as object in your blade view file.
Instead of getting data like this:
$post->STATUS
Try using like this:
$post['STATUS']
Don't use ->toArray()
Pass data as below & variables will get displayed
return view('home', ['posts' => $posts)]);

When I'm going to add data an error appears "Call to a member function count() on null"
View
#foreach ($data as $row)
<tr>
<td>{{ $row->customer}}</td>
<td>{{ $row->vessel}}</td>
<td>{{ $row->scopejob}}</td>
<td>{{ $row->pergantian_sparepart}}</td>
<td>{{ $row->teknisi}}</td>
<td>{{ $row->tahun}}</td>
<td>{{ $row->keterangan}}</td>
<td>{{ $row->images->count()}}</td>
<td>{{ $row->files->count()}}</td>
<td>
FOTO
FILE
EDIT
<a href="#" class="btn btn-danger delete m-1" data-id="{{ $row->id}}" data-customer="{{ $row->customer}}" >DELETE</a>
</td>
</tr>
#endforeach
Controller rekap:
public function insert_rekap(Request $request) {
// dd($request->all());
$this -> validate($request,[
'customer'=>'required',
'vessel'=>'required',
'scopejob'=>'required',
'pergantian_sparepart'=>'required',
'teknisi'=>'required',
'tahun'=>'required',
'keterangan'=>'required'
]);
$data = rekap::create($request->all());
if($request->hasFile("images")){
$images=$request->file("images");
foreach($images as $image){
$imageName=time().'_'.$image->getClientOriginalName();
$request['rekap_id']=$data->id;
$request['image']=$imageName;
$image->move(public_path("/images_rekap"),$imageName);
Image_rekap::create($request->all());
}if($request->hasFile("files")){
$files=$request->file("files");
foreach($files as $file){
$fileName=time().'_'.$file->getClientOriginalName();
$request['rekap_file_id']=$data->id;
$request['file']=$fileName;
$file->move(\public_path("/rekap_file"),$fileName);
file_rekap::create($request->all());
}
}
}
return redirect()->route('rekap')->with('success','Data Berhasil Ditambahkan');
}
but the data is successfully entered into the database, and what steps should I take to correct the error
error tells you that images or files or both variables are null, looks like you don't use eager loading
quick and dirty way is to use optional helper
<td>{{ optional($row->images)->count()}}</td>
<td>{{ optional($row->files)->count()}}</td>
if you need only count then better approach is to use eloquent counting related models
// controller
$data = rekap::withCount(['images', 'files'])
// other selecting rules
//->where ...
->get();
return view('view_name', ['data'=>$data]);
now in every $row of $data you have fields images_count and files_count
<td>{{ $row->images_count }}</td>
<td>{{ $row->files_count }}</td>
also you can rename count variables like rekap::withCount(['images as imagesCount', 'files as filesCount'])
<td>{{ $row->imagesCount }}</td>
<td>{{ $row->filesCount }}</td>
Try
<td>{{ $row->images ? $row->images->count() : '' }}</td>
Can anyone help me complete this? I'm a beginner and this is my first time using Laravel and PHP.
<?php
#foreach ($peminjaman as $value)
<tbody>
<tr>
<td>{{ ++$i }}</td>
<td>{{ $value->no_peminjaman }}</td>
<td>{{ $value->no_bmn }}</td>
<td>{{ $value->no_seri }}</td>
<td>{{ $value->kelengkapan }}</td>
</tr>
</tbody>
#endforeach
You need to add links(), so that the links for pagination can be generated in your view.Just have a look at the documentation here and you're good to go:https://laravel.com/docs/5.7/pagination
Hope this helps.
When you do :
$peminjaman = Model::paginate(10);
The $peminjaman is an instance of Illuminate\Pagination\LengthAwarePaginator.
In your case it seems like somewhere you have $peminjaman->id which as a result throwing the error you mentioned.
There is no property called id present on the LengthAwarePaginator paginator instance.
I'm currently working on Laravel for the first time and i'm stuck with an issue. I have an export excel button on my tickets list page but It exports all the tickets ever created. Is there a way to only export weekly tickets in excel format based on the current date?
excel form :
#foreach (\App\Tickets::All() as $ticket)
<tr>
<td>{{ $ticket->societe}}</td>
<td>{{ $ticket->intervenant}}</td>
<td>{{ $ticket->assistance->level}}</td>
<td>{{ $ticket->message}}</td>
<td>{{ $ticket->urgence->niveau}}</td>
<td>{{ $ticket->statut}}</td>
<td>{{ $ticket->utilisateur->name}}</td>
</tr>
#endforeach
Excel function in ticketscontroller :
public function exportxls(){
Excel::create('tickets', function($excel){
$excel->sheet('tickets', function($sheet){
$sheet->loadView('export.ticketsexcel');
})->export('xls');
});
return redirect('/');
}
Thanks in advance.
You should have sent data from controller to the view and export only weekly tickets you can modify your query.
public function exportxls(){
$weeklyTickets = \App\Tickets::whereBetween('created_at', array(date("Y-m-d", strtotime("-7 days")), date('Y-m-d'))->get();
Excel::create('tickets', function($excel) use ($weeklyTickets){
$excel->sheet('tickets', function($sheet) use ($weeklyTickets){
$sheet->loadView('export.ticketsexcel', array('weeklyTickets' => $weeklyTickets));
})->export('xls');
});
return redirect('/');
}
In this function change "created_at" field according to your database field.
And in view you can modify it like this:
#foreach ($weeklyTickets as $ticket)
<tr>
<td>{{ $ticket->societe}}</td>
<td>{{ $ticket->intervenant}}</td>
<td>{{ $ticket->assistance->level}}</td>
<td>{{ $ticket->message}}</td>
<td>{{ $ticket->urgence->niveau}}</td>
<td>{{ $ticket->statut}}</td>
<td>{{ $ticket->utilisateur->name}}</td>
</tr>
#endforeach
Hope this helps you.
Compare two different columns from two different tables with if statement and show other column's data from either table in laravel 5.2
controller like:
public function labDetails(){
$users = DB::table('users')->lists('lab_name');
$labdetails = Labdetails2::paginate(20);
return View('labdetails')
->with('users', $users)
->with('labdetails', $labdetails);
}
here i want to match users table's 'lab_name' column with labdetails2 table's 'lab_name' column and if they matched show only the related data from labdetails table.
N.B. I am working with an old database where there's no relationship among tables.
views like:
<form action="" method="">
<select name="state" onchange="getValue(this)">
<option value="">Select Lab</option>
#foreach ($users as $key => $user)
<option value="{{ $user }}">{{ $user }}</option>
#endforeach
</select>
<input type="submit" value="Submit">
#foreach ($labdetails as $labdetail)
<tbody>
<tr>
<td>{{ $labdetail->sl }}</td>
<td>{{ $labdetail->lab_name }}</td>
<td>{{ $labdetail->pc_name }}</td>
<td>{{ $labdetail->pc_ip }}</td>
<td>{{ $labdetail->mac1 }}</td>
<td>{{ $labdetail->assetno }}</td>
<td>{{ $labdetail->pc_type }}</td>
<td>{{ $labdetail->processor }}</td>
<td>{{ $labdetail->motherboard }}</td>
<td>{{ $labdetail->ram }}</td>
<td>{{ $labdetail->hdd }}</td>
<td>{{ $labdetail->location }}</td>
<td>{{ $labdetail->department }}</td>
<td>{{ $labdetail->entrydate }}</td>
<td>{{ $labdetail->comment }}</td>
</tr>
</tbody>
#endforeach
Please help me what should I do with the controller & views...
You can retrieve only the matches record this way
$users = DB::table('users')->lists('lab_name'); // this retrieves all lab_name as array.
Then, to retrieve only the matches labdetails
$labdetails = Labdetails2::whereIn('lab_name',$users)->paginate(20);
DB::table('users')
->join('labdetails2', 'users.lab_name', '=', 'labdetails2.lab_name')
->select('labdetails2.lab_name', 'labdetails2.pc_name')
->get()
in select(), white down the fields you required.
Here, labdetails2 and users are the table name.
this code finally worked for me:
public function showLabDetails(Request $request){
$q = $request -> request -> all();
$labdetails = Labdetails2::whereIn('lab_name', $q)->get();
return View('showlabdetails')
->with('labdetails', $labdetails);
}
thanks to everyone for helping me.
I'm new in Laravel. I'm storing 3 types of user in my users table:
admin : user_type_id = 1
agent : user_type_id = 2
farmer : user_type_id = 3
user_type_id column is in the users table.
In one of my Blade files, I want to only show the names of the agents. Here is my foreach loop, which is importing all 3 types of the user (it's showing the names of admins, agents and farmers).
#foreach($farmerPoint->user as $agent)
<tr>
<td>{{ $agent->name }}</td>
<td>{{ $agent->phone }}</td>
</tr>
#endforeach
This is probably more of a logic issue than a Laravel issue. NOTE that I would suggest you limit the $agents instead using your query (where) rather than this way, BUT:
#foreach($farmerPoint->user as $agent)
#if ($agent->user_type_id === 2)
<tr>
<td>{{ $agent->name }}</td>
<td>{{ $agent->phone }}</td>
</tr>
#endif
#endforeach
You can use a simple blade #if() statement like so:
#foreach($farmerPoint->user as $agent)
#if ($agent->user_type_id === 2)
<tr>
<td>{{ $agent->name }}</td>
<td>{{ $agent->phone }}</td>
</tr>
#endif
#endforeach
Or you can use a collection where() since all eager / lazy loaded relations are returned in collections:
http://laravel.com/docs/5.1/collections#method-where
#foreach($farmerPoint->user->where('user_type_id', 2) as $agent)
<tr>
<td>{{ $agent->name }}</td>
<td>{{ $agent->phone }}</td>
</tr>
#endforeach
