Laravel paginate on query builder - php

If i use
$categories= Category::orderby('id', 'desc')->paginate(3);
it works but if i use
$categories= Category::with('subcategories')->orderby('id', 'desc')->paginate(3);
paginate doesn't work! how to fix it?
UPDATE:
<tbody>
#foreach ($categories as $category)
#foreach($category->subcategories as $sub)
<tr>
<td class="text-center">{{ $sub->id }}</td>
<td class="text-center">{{ $sub->title }}</td>
<td class="text-center">{{ $sub->category->title }}</td>
</tr>
#endforeach
#endforeach
</tbody>

You need to approach this problem from the opposite side of the relationship.
Find all subcategories, with their parent category, order them by ID descending and then paginate to three per page.
$subcategories = Subcategory::with('category')
->orderBy('id', 'desc')
->paginate(3);
<tbody>
#foreach($subcategories as $subcategory)
<tr>
<td class="text-center">{{ $subcategory->id }}</td>
<td class="text-center">{{ $subcategory->title }}</td>
<td class="text-center">{{ $subcategory->category->title }}</td>
</tr>
#endforeach
</tbody>

Laravel view foreach with two properties

i need help with my foreach loop in view
Controller.php
$expenses = Expense::groupBy('category_id')->selectRaw('sum(amount) as sum, category_id')->pluck('sum','category_id');
$categories = Category::all();
return view('dashboard.index', compact('expenses','categories'));
index.php
<table class="table">
<thead>
<th>Category</th>
<th>Expenses</th>
</thead>
<tbody>
#foreach($categories as $category)
<tr>
<td>{{ $category->name }}</td>
#foreach($expenses as $expense)
<td>{{ $expense }}</td>
#endforeach
</tr>
#endforeach
</tbody>
</table>
I get the output like this.
enter image description here
It outputs the expense 2 times, is there a limiter for "foreach loop" or is there another way on doing this?
You need to add a condition for that $category->id is the same as category_id
#foreach($expenses as $key => $expense)
#if($key == $category->id)
<td>{{ $expense }}</td>
#endif
#endforeach
The right way to do it is by using join or relationship.
$expenses = Expense::join('categories','categories.category_id','expenses.category_id')->groupBy('expenses.category_id')->selectRaw('sum(expenses.amount) as sum, expenses.category_id','categories.name')->get();
<table class="table">
<thead>
<th>Category</th>
<th>Expenses</th>
</thead>
<tbody>
#foreach($expenses as $expense)
<th>{{ $expense->name }}</th>
<td>{{ $expense->sum }}</td>
#endforeach
</tbody>
</table>
You should limit the results in controller, but here's how you can accomplish this in a blade. Not pretty
#foreach ($element['subs'] as $item)
#if($loop->index < 10)
// Your code
#endif
#endforeach
You should compare category_id with category->id.
#foreach($categories as $category)
<tr>
<td>{{ $category->name }}</td>
#foreach($expenses as $expense)
#if($expense->category_id == $category->id )
<td>{{ $expense->sum }}</td>
#endif
#endforeach
</tr>
#endforeach

Thanks!!
I would do it as so:
In the controller, select the customers eager loading the vehicles.
$customers = Customer::with('vehicles')->get();
return view('customers')->with('customers', $customers);
In the view:
<table>
#foreach($customers as $index => $customer)
<tr>
<td rowspan="$customer->vehicles->count()">
{{ $index+1 }}
</td>
<td rowspan="$customer->vehicles->count()">
{{ $customer->fullName }}
</td>
<td rowspan="$customer->vehicles->count()">
{{ $customer->phone }}
</td>
<td> {{$customer->vehicles[0]->licensePlate }} </td>
<td> {{$customer->vehicles[0]->brandName }} </td>
<td> {{$customer->vehicles[0]->modelName }} </td>
</tr>
#for($i=1;$i<$customer->vehicles->count())
<tr>
<td> {{$customer->vehicles[$i]->licensePlate }} </td>
<td> {{$customer->vehicles[$i]->brandName }} </td>
<td> {{$customer->vehicles[$i]->modelName }} </td>
</tr>
#endfor
#endforeach
</table>
<table class="table">
<thead class="thead-dark">
<tr>
<th scope="col">#</th>
<th scope="col">Customer</th>
<th scope="col">Licence Number</th>
<th scope="col">Brand</th>
<th scope="col">Brand Type</th>
</tr>
</thead>
<tbody>
#foreach($report_data as $index => $item)
<tbody class="table-content">
<tr>
<td>{{ $index+1 }}</td>
<td style="text-align:left;">{{ $item->customer_fullName }}</td>
<td>{{ $item->customer_phone }}</td>
<td>{{ $item->customer_detail_licensePlate }}</td>
<td>{{ $item->vehicle_brand_name }}</td>
<td>{{ $item->vehicle_model_name }}</td>
</tr>
</tbody>
#endforeach
</tbody>
use this CDN for Bootstrap style
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">
You need not to iterate tbody everytime, just iterate <tr></tr> as below
<table>
<thead>
<tr>
<th>No</th>
<th>Customer</th>
<th>Phone</th>
<th>License Number</th>
<th>Brand</th>
<th>Brand Type</th>
</tr>
</thead>
<tbody class="table-content">
#foreach($report_data as $index => $item)
<tr>
<td>{{ $index+1 }}</td>
<td rowspan="2" style="text-align:left;">{{ $item->customer_fullName }}</td> //rowspan should be in some condition
<td>{{ $item->customer_phone }}</td>
<td>{{ $item->customer_detail_licensePlate }}</td>
<td>{{ $item->vehicle_brand_name }}</td>
<td>{{ $item->vehicle_model_name }}</td>
</tr>
#endforeach
</tbody>
</table>

Laravel 5.4 - controller logic to show the status of a blog post on view

new to Laravel, and just having this problem that I couldn't figure it out.
I have a post controller set up to query out all blog posts. On the database, I have a integer column and named as "status", 0 as inactive, 1 as active. The question is how and where to place the logic to check whetherthe status is 0 or 1, and show "inactive" or "active" in the view. Thanks in advance.
public function index()
{
$posts = Post::where('user_id', 1)->orderBy('id', 'desc')->paginate(5);
return view('post.index')->withPosts($posts);
}
Here is the view
<table class="table">
<tr>
<th>Date Created</th>
<th>Title</th>
<th>Status</th>
</tr>
#foreach ($posts as $post)
<tr>
<td>{{datePretty($post->created_at) }}</td>
<td>{{ $post->title }}</td>
<td></td>
</tr>
<br>
#endforeach
</table>
you can have that logic inside your blade template:
#foreach ($posts as $post)
<tr>
<td>{{datePretty($post->created_at) }}</td>
<td>{{ $post->title }}</td>
<td>#if($post->status) active #else inactive #endif</td>
</tr>
<br>
#endforeach

Custom query using DB::select() on laravel 4.2 controller

I had used a custom query in my controller in laravel here is my code in my controller:
public function c_viewSystemUser()
{
$title = "View System Users";
$jSu = DB::select(DB::raw("SELECT dbo_systemusers.SystemUserID,dbo_systemtypes.SystemType, dbo_systemusers.SystemUserName INNER JOIN dbo_systemtypes ON dbo_systemusers.SystemUserTypeID = dbo_systemtypes.SystemUserTypeID"));
return View::make('ssims.view_systemUser',compact('title','jSu'));
}
I wanted to display its result in my blade file view_systemUser
here is my code inside the view:
#if ($jSu)
<table class="table table-striped table-hover" id="detailTable">
<thead>
<tr>
<th>System User ID</th>
<th>SystemUser Type ID</th>
<th>System UserName</th>
<th>System User Description</th>
</tr>
</thead>
<tbody>
#foreach ($jSu as $vu)
<tr>
<td>{{ $vu->dbo_systemusers.SystemUserID }}</td>
<td>{{ $vu->dbo_systemtypes.SystemType }}</td>
<td>{{ $vu->dbo_systemusers.SystemUserName}}</td>
<td>{{ $vu->dbo_systemusers.SystemUserDescription}}</td>
</tr>
#endforeach
</tbody>
</table>
And I am having an error:
Undefined property: stdClass::$dbo_systemusers (View:
C:\xampp\htdocs\laravel3\app\views\ssims\view_systemUser.blade.php)
Any suggestions?
Try this:
#foreach ($jSu as $key => $vu)
<tr>
<td>{{ $vu->SystemUserID }}</td>
<td>{{ $vu->SystemType }}</td>
<td>{{ $vu->SystemUserName}}</td>
<td>{{ $vu->SystemUserDescription}}</td>
</tr>
#endforeach
You forgot to join dbo_systemusers with dbo_systemtypes.
Try this code
SELECT dbo_systemusers.SystemUserID,dbo_systemtypes.SystemType, dbo_systemusers.SystemUserName from dbo_systemusers INNER JOIN dbo_systemtypes ON dbo_systemusers.SystemUserTypeID = dbo_systemtypes.SystemUserTypeID
And Try this on View page
#foreach ($jSu as $vu)
<tr>
<td>{{ $vu->SystemUserID }}</td>
<td>{{ $vu->SystemType }}</td>
<td>{{ $vu->SystemUserName}}</td>
<td>{{ $vu->SystemUserDescription}}</td>
</tr>
#endforeach
