How to only show all articles that contains a particular value? - php

Currently using Laravel 8, I have to show on a page all articles but only the ones that contain a specific row value in my Database. For instance, in this one, I have a column in the desired table that is called "is_reserved" as TinyInt acting as a True or false (1-0).
I have searched absolutely everywhere and I cannot understand nor find the right syntax for filtering and show only articles that aren't reserved (is_reserved = 0).
In my blade view file, I have a #foreach loop that fetches my item from my controller, like the following below. Which works by the way, just not the way I intend it to be. I'm out of ideas.
TL:DR: I just want to be able to show all items from my database but only the ones with a specific row value.
<section class="row justify-content-evenly mt-5 mx-sm-3">
#foreach ($donations as $donation)
<article class="box col-md-5 col-sm-12 row p-3 mt-md-3 mt-sm-5 d-flex justify-content-around">
<img src="{{ $donation->image }}" alt="image" class="col" style="border-radius: 100%;">
<div class="col">
<p style="text-align: justify;">{{ Str::limit($donation->description, 80) }}</p>
<div class="d-flex justify-content-start flex-column text-left" style="width: auto; height: 100px;">
<h5>Location: Quebec</h5>
<p>Meteo: Cold</p>
<div class="row justify-content-between">
<button class="col-5 btn yellowBtn">reserve</button>
<a class="col-5 btn greenBtn" href="{{route('view-item', $donation->id)}}">View</a>
</div>
</div>
</div>
</article>
#endforeach

Move the logic to the controller / service before looping through them, then send the necessary rows to your blade (probably with a $is_reserved boolean in the array/object)
Keep in mind that if you're diving into logic in the blade / template file itself, it's best to move it back a step and just provide the template the simplest data you can.
Taking your question as an example, before sending the rows to the template, and just show the ones that match your need.
e.g.
$rows = DB::table('your_table')->where('is_reserved', '1')->get();
return $rows; //or extend your template here
Otherwise, you can ad an #if condition right to your template, and render only if ceratin condition is met

Chunking Results In Laravel Blade Failing Due To Callback

I am trying to chunk the results of a laravel collection in my blade template to have 3 columns of records expanding to as many rows as needed. What I have is...
#foreach(Auth::user()->apps()->chunk(3) as $chunk)
<div class="row row-grid gx-0">
#foreach($chunk as $app)
<a href="{{ $app->url }}" class="dropdown-item text-decoration-none p-3 bg-none">
<div class="position-relative">
<i class="fa-solid fa-circle-fill position-absolute text-theme top-0 mt-n2 me-n2 fs-6px d-block text-center w-100"></i>
<i class="fa-solid fa-{{ $app->icon }} h2 opacity-5 d-block my-1"></i>
</div>
<div class="fw-500 fs-10px text-white">{{ ucfirst($app->alias) }}</div>
</a>
#endforeach
</div>
#endforeach
But I am getting the error Too few arguments to function Illuminate\Database\Eloquent\Relations\BelongsToMany::chunk(), 1 passed in /app/storage/framework/views/7d3f05473ba9eb01ea58150355cc97e13e862587.php on line 1 and exactly 2 expected. Taking a look at the Laravel source in Github it appears as a callback function is required which handles the looping for each chunk but this only really works if done from within PHP itself, within a blade template I cant figure out how to to a chunk with a callback. All the information I have been able to find online for Laravel blade chunking shows that this should be working.
My controller method is...
$userApps = Auth::user()->apps();
$chunk = ceil($userApps->count() / 3);
return view('apps', ['apps' => $userApps, 'appsChunk' => $chunk]);

Laravel 8 - reusable code block, change variable depending on a page for charts?

I want to display multiple charts in a single page or different pages. How can I reuse the blade file instead of repeating/retyping the code?
I created a plain blade file _chart-widget.blade.php and I want the variable value to change depending on the page, or depending on what I want to set the variable in each <section> of a page
<!--begin::Charts Widget 1-->
<div class="card {{ $class ?? '' }}">
<!--begin::Header-->
<div class="card-header border-0 pt-5">
<!--begin::Title-->
<h3 class="card-title align-items-start flex-column">
<span class="card-label fw-bolder fs-3 mb-1">Recent Statistics</span>
<span class="text-muted fw-bold fs-7">More than 400 new members</span>
</h3>
<!--end::Title-->
<!--begin::Toolbar-->
<div class="card-toolbar">
<!--begin::Menu-->
<button type="button" class="btn btn-sm btn-icon btn-color-primary btn-active-light-primary" data-kt-menu-trigger="click" data-kt-menu-placement="bottom-end">
{!! theme()->getSvgIcon("icons/duotune/general/gen024.svg", "svg-icon-2") !!}
</button>
{{ theme()->getView('partials/menus/_menu-1') }}
<!--end::Menu-->
</div>
<!--end::Toolbar-->
</div>
<!--end::Header-->
<!--begin::Body-->
<div class="card-body">
<!--begin::Chart-->
<div id="kt_charts_widget_1_chart" style="height: 350px"></div>
<!--end::Chart-->
</div>
<!--end::Body-->
</div>
<!--end::Charts Widget 1-->
How can I make the code above dynamic and reusable when I #include it?
You can include views in Laravel blade template.
here you can read more.
Just use like this:
<div>
#include('_chart-widget')
</div>
If you need to pass data to your widget component, just give parameters as an array to your component:
#include('view.name', ['status' => 'complete'])
If you want variables to be different in each page simply pass vairables from Controller.If you are on the same page and including same blade multiple times this can help you:
#include('view.name', ['code' => 'complete'])
This will set different values for $code variable in different sections.

Pass database data to several divs from one loop with php and laravel

I have a paging setup, which can be shown as such:
<div class="page__A4">
</div>
<div class="page__A4">
</div>
<div class="page__A4">
</div>
Data is then passed from my SQL database using PHP, through a for loop, e.g:
#foreach($data as $value)
<div class="element">
{{$value}}
</div>
#endforeach
which would leave the final markup:
<div class="page__A4">
#foreach($data as $value)
<div class="element">
{{$value}}
</div>
#endforeach
</div>
<div class="page__A4">
</div>
<div class="page__A4">
</div>
My $value is dynamic in height, and when the amount of $value's exceeds the first page__A4 element in height, I want it to proceed to the next page.
The real issue relies in that I am unable to use Javascript. I need to print these pages to PDF, which is done by combining a laravel view with a SASS styling file - meaning javascript wont be loaded in my final printed product.
Is there a way to achieve this, using a combination of laravel/php/SASS?
You have to class="A_4" dynamic too if you want to use it in javascript.
foreach($values as $ value){
<div class="'example'.$value.">
</div>
}

Laravel view links and web.php routes messed up

I'm making a forum with themes and topics. If a user clicks on a theme, he/she gets to see all the topics within that theme. Here we encounter the first problem. In the theme.blade.php I have a title: <span class="card-title">{{ $theme->theme_title }} - Topics</span>. This title is supposed to show the title of the theme that the user clicked on. But it shows (just a wild guess) some random theme title from the database that is not even connected to this topic.
Now I made an extra view for the user. If the user clicks on a topic from the selected theme. He/she is supposed to redirect to the topic that he/she clicked on but instead its shows (again) some random topic from the database that is not connected to the topic/theme at all. Instead of the topic that the user clicked on. In this GIF http://imgur.com/a/vOQFT you can see the problem If u look at the profile picture and username. Maybe the problem is in the Web.phpor somewhere else, I don't know. Sorry for the long story but I couldn't figure out how say this in a better way. I think I switched some things up in the code.
Here is the every file of code where this problem may occur
Web.php
Route::get('/', 'ThemesController#index')->name('home');
Route::get('/theme/{theme_id}/topics', 'ThemesController#show')->name('showtheme');
Route::get('/theme/{theme_id}/topics/{topic_id}', 'TopicsController#show')->name('showtopic');
Route::group(['middleware' => 'App\Http\Middleware\AdminMiddleware'], function() {
//THEMES
Route::get('/theme/{theme_id}/edit', 'ThemesController#edit')->name('edittheme');
Route::patch('/theme/{theme_id}/edit', 'ThemesController#update')->name('updatetheme');
Route::get('/theme/create', 'ThemesController#create')->name('createtheme');

});
Route::get('user/profile', 'UserController#profile')->name('showprofile');
Route::post('user/profile', 'UserController#update_avatar');

ThemesController.php (Only show method)

}
TopicsController.php(Only show method)
public function show($id)
{
$theme = Theme::find($id);
$topic = Topic::find($id);
return view('topics.topic')->with('theme', $theme)->with('topic', $topic);
}
Thanks for looking at my code. This problem has been sitting here for quite a while and I want to move on. Thanks for your help!
Your controller code simply finds the theme with ID $id, and the topic (singular!) with ID $id. That particular topic may not appear in that particular theme at all. They likely have nothing to do with each other.
To find the topics belonging to the theme with ID $id, you would do this:
$theme = Theme::find($id)->with('topics');
(this assumes your model relationships are set up correctly, you have not show us those). See the docs on eager loading.
To access the topics in your view, do something like this:
#foreach ($theme->topics as $topic)
...
{{ $topic->user->username }}
...
While developing, you can simply
return $theme;
in your controller to see the structure of the data, so you can work out how to handle and iterate over it.

JQuery UI Sortable + Laravel Collection Chunk: Rows draggable instead of single elements

I've got a Problem. As I am using Bootstrap, I have rows containing 3 images each. In order to do it like this (because the images come from the databse) I'm using the chunk() function available in Laravel. This allows me to insert a .row, then show 3 images with a .col-md-4 each and then creates another .row and so on.
<div id="sortable-image-container">
#foreach($product->images->chunk(3) as $chunk)
<div class="row">
#foreach($chunk as $image)
<div class="col-md-4">
<div class="card">
<div class="header text-right">
X
</div>
<div class="content">
<img src="http://placehold.it/500x500" alt="" class="center-block img-responsive">
</div>
</div>
</div>
#endforeach
</div>
#endforeach
</div>
Now I want to integrate jQuery UI's Sortable to those images using:
$('#sortable-image-container').sortable({});
However, it declares a row as a draggable element, instead of a product-image box.
In the picture here are two rows, the first containing 3 images boxes and the second one image box. as you can see I am grabbing the entire row to drag instead of a single element. Because I'm using chunk() I can't find a nice solution to make single elements draggable.
Seem to have figured it out by myself. There is an items option which defaults to: > *. By setting: items: '> .row > *', I can now grab single elements.
$('#sortable-image-container').sortable({
items: '> .row > *'
});
