I am creating a bookmark system where users can bookmark a particular product. When I attempt to load the icon for a bookmarked item, it shows both the icon, i.e., before the bookmark icon and the bookmarked icon.
Here's a simple explanation.
[{"id":2,"bookmark_id":"HRTKB1607974280","user_id":"HCTK001606935187","document_id":"HRTKD1607941923","created_at":"2020-12-14T19:31:20.000000Z","updated_at":"2020-12-14T19:31:20.000000Z"},
{"id":3,"bookmark_id":"HRTKB1607974280","user_id":"HCTK001606935187","document_id":"HRTKD1607941923","created_at":"2020-12-14T19:31:20.000000Z","updated_at":"2020-12-14T19:31:20.000000Z"}]
Now in the Blade file, I am using the following code.
#foreach($documents as $data)
#foreach($bookmarks as $bookmark)
#if($data->document_id === $bookmark->document_id)
<li class="active-bookmark">
<a href="/add_bookmark/{{$data->document_id}}"
data-toggle="tooltip" data-placement="left"
title="Bookmark">
<i class="lar la-bookmark"></i>
</a>
</li>
#break
#else
<li>
<a href="/add_bookmark/{{$data->document_id}}"
data-toggle="tooltip" data-placement="left"
title="Bookmark">
<i class="lar la-bookmark"></i>
</a></li>
#endif
#endforeach
#endofforeach
But for some reason, this is happening.
Am I doing something wrong, or is there any easy way to do this?
You are iterating through that loop and will always output a icon until the true condition is met. What happens when the first iteration it isn't met, it has to iterate again and output another icon.
Assuming these are all Collections you can do this without looping the bookmarks:
#foreach ($documents as $document)
...
#if ($bookmarks->contains('document_id', $document->id))
// have the bookmark
#else
// add bookmark
#endif
...
#endforeach

This is the example while looping
despite having a condition and relation many too many it seems that the case
#foreach (\App\ClientDocument::where('id_client', $clients->id)->get() as $item)
#if (\App\Document::where('id',$item->id_document)->get())
<a class="img-fluid " href="{{asset('images/'.$item->file)}}" download="{{asset('images/'.$item->file)}}" alt="" name="download" > Telecharger </a>
#endif
#endforeach
in the above snippet
#foreach (\App\ClientDocument::where('id_client', $clients->id)->get() as $item)
#if (\App\Document::where('id',$item->id_document)->get())
<a class="img-fluid " href="{{asset('images/'.$item->file)}}" download="{{asset('images/'.$item->file)}}" alt="" name="download" > Telecharger </a>
#endif
#endforeach
code is absolutely fine, but there might be the possibility, you are running with duplicate data, you can use this also.
\App\ClientDocument::where('id_client', $clients->id)->distinct('id_client')->get()
and instead of using #if (\App\Document::where('id',$item->id_document)->get())
you can use
#if (\App\Document::where('id',$item->id_document)->firstOrFail())
#if (\App\Document::where('id',$item->id_document)->count())
That's it.
first you shouldn't loading data inside blade files
do it inside controller function
then you should create relationship inside ClientDocument model name document
and in your blade you can do that
$item->document
or whatever you want
I'm using a Laravel 5.7 in an old web project last year 2019 but now I encountered a very weird bug.
This is a website that when you add a new game, it will show to the menu list and if it is featured it will show to the homepage content.
this is the table ['game_id', 'name', 'key', 'status', 'order', 'is_featured']
in the header view I put this code:
<ul class="nav-menu">
<li class="{{ ($page == "games" ? 'menu-active' : '') }} submenu dropdown"><a href="/games" >Games</a>
<ul class="dropdown-menu">
#foreach(GetPublishedGames() as $game)
<li class="nav-item">{{$game->name}}</li>
#endforeach
</ul>
</li>
...
calling this helper code GetPublishedGames()
function GetPublishedGames(){
$data = DB::table("game")->where("status", 1)->orderBy("order")->get();
return $data;
}
in the homepage controller I had this line
"feat_games" => Game::where("status", 1)->where("is_featured", 1)->orderBy("order")->limit(5)->get(),
that calls in the homepage view:
#if(count($feat_games))
#foreach($feat_games as $feat_game)
<div class="feat-game-item wow fadeInUp">
... some content ...
</div>
#endforeach
#endif
I have no idea why this happening, it works before in the local and development stage. I did tried to clear cache.
any idea?
I am brand new to Laravel and I'm running Version 6.
I want my view to display a button if one of my MySQL tables has rows that meet a specific condition but I'm having trouble figuring out how to code it - and even WHERE to code it - within my Laravel application.
My MySQL table is called diary_entries and various users of the system will contribute zero to n rows to it. Each row of the table contains a user id called client. When a given user goes to the Welcome view, I want the view to determine if that user currently has any rows in the diary_entries table. If he does, I want to display a button that will take him to another page where the entries can be displayed or edited or deleted.
I think I want to construct an #if that counts the number of records for that user; if the count is greater than zero, I want to display the button, otherwise the button is not displayed.
The problem is that I can't figure out how to code this. I've looked at the examples in the Eloquent section of the manual but they aren't particularly clear to me. I found a note near the top that said the count() function expects a Collection as an argument and that the result of an Eloquent statement is always a Collection so I guessed that I just have to execute an Eloquent query, then apply count() to the resulting Collection. But every variation of that idea which I've tried has thrown exceptions.
Here was the guess that seemed most logical to me:
#extends('layout');
#section('content');
<div class="content">
<img class="centered" src="/images/sleeping-cat.jpg" alt="sleeping cat" height="250">
<div class="title m-b-md">
<h1> Sleep Diary </h1>
</div>
<div>
<h3>{{Auth::user()->name }}</h3>
</div>
<div>
#if (count(App\DiaryEntry::select('*')->where('client', Auth::user()->name) > 0))
<p>
<a class="btn btn-primary"> View / edit existing sleep diary entries </a>
</p>
#endif
</div>
<div>
<p>
<a class="btn btn-primary" href="/diaryEntries"> Create a new sleep diary entry </a>
</div>
</div>
#endsection
This is obviously wrong because it throws an exception so how do I make it right? Does the building of the collection have to move into the Controller? If so, how do I invoke the method and see its result? Or can I do something like I have already done but just adjust the syntax a bit?
EDIT
I've imitated Sehdev's suggestion but I get this error:
$count is undefined
Make the variable optional in the blade template. Replace {{ $count }} with {{ $count ?? '' }}
Here is my welcome view:
#extends('layout');
#section('content');
<div class="content">
<img class="centered" src="/images/sleeping-cat.jpg" alt="sleeping cat" height="250">
<div class="title m-b-md">
<h1>Sleep Diary</h1>
</div>
<div>
<h3>{{ Auth::user()->name }}</h3>
</div>
<div>
#if ($count) > 0))
<p>
<a class="btn btn-primary">View/edit existing sleep diary entries</a>
</p>
#endif
</div>
<div>
<p><a class="btn btn-primary" href="/diaryEntries">Create a new sleep diary entry</a>
</div>
</div>
#endsection
And this is the relevant function from DiaryEntryController:
public function countEntriesOneUser()
{
$count = DiaryEntry::select('*')->where('client', Auth::user()->name)->count();
view("welcome", compact("count"));
}
Should the compact function be returning $count instead of count? I can't find the compact function in the manual with the search function so I'm not clear what it does or what the proper syntax is. I just tried changing the last line of the function to
view("welcome", $count);
but that produced the same error.
Try this,
#php
$count=\App\DiaryEntry::where('client', Auth::user()->name)->count();
#endphp
#if($count>1)
<p><a class="btn btn-primary">View/edit existing sleep diary entries</a></p>
#endif
Using App\DiaryEntry::select('*')->where('client', Auth::user()->name) directly on your blade template is a bad practise.
You can execute your question in your controllers method and then pass the result on your view file
Your function
function test(){
$count = DiaryEntry::select('*')->where('client', Auth::user()->name)->count(); // get the total no of records using count
view("index", compact("count")) // pass your count variable here
}
then you can directly use $count in your #if condition
Your blade template
<div>
#if ($count > 0)
<p><a class="btn btn-primary">View/edit existing sleep diary entries</a></p>
#endif
</div>
I'm making a College Administration website where a professor can log in.
I have a dashboard, where my dynamically generated button should be placed: (right now it just has dummy buttons!)
Generated by this view file, which I will have to modify soon:
<div class="container d-flex flex-column align-items-center justify-content-center">
<h1>IA DASHBOARD</h1>
<br>
<div class="grid2">
SUBCODE 1</button>
SUBCODE 2</button>
SUBCODE 3</button>
</div>
Tables in the Database:
the table iamarks contains the data (student info, and marks) that is to be displayed after /subcode/{subcode} narrows it down to records of just the students that are in the class assigned to current logged-in professor.
classroom_mappers is a table used to map a professor to a classroom with a subject. It makes sure that one classroom only has one professor for a particular subject.
the routes currently in my web.php:
route::get('/ia', 'IAController#show')->middleware('auth');
Route::get('/subcode/{subcode}', 'IAController#showTable')->middleware('auth');
...and these are the methods inside my controller:
//shows buttons to the user:
public function show(){
$subcodes = DB::table('classroom_mappers')
->select('subcode')
->where([['PID','=', auth()->user()->PID]])
->get();
return view('ia',compact('subcodes'));
}
//when user clicks a button, subcode is to be generated and a table is to be shown:
//it works, I tried it by manually typing in subcode value in URL.
public function showTable($subcode){
$sem = DB::table('classroom_mappers')
->where([['PID','=', auth()->user()->PID],
['subcode','=',$subcode]])
->pluck('semester');
$division = DB::table('classroom_mappers')
->where([['PID','=', auth()->user()->PID],
['semester','=',$sem],
['subcode','=',$subcode]])
->pluck('division');
$data = DB::table('iamarks')
->where([['semester','=',$sem],
['division','=',$division],
['subcode','=',$subcode]])
->get();
return view('subcode',compact('data'));
}
My Problem:
To be able to generate the {subcode} in the URL dynamically, I want to create buttons in the dashboard using the data $subcodes. The controller hands over the $subcodes (an array of subject codes which belong to logged in professor) which are to be made into buttons from the show() method.
The buttons should have the name {subcode} and when clicked, should append the same subject code in the URL as {subcode}.
How do I make use of $subcodes and make the buttons dynamically?
How do I make sure the buttons made for one user are not visible to another user?
I managed to find the solution, thanks to Air Petr.
Apparently, you can't nest blade syntax like {{some_stuff {{ more_stuff }} }} and it generates a wrong php code. I modified the solution by Air Petr to:
<div class="grid2">
#foreach ($subcodes as $subcode)
<a href="<?php echo e(url('/subcode/'.$subcode->subcode));?>">
<button class="btn btn-outline-primary btn-custom-outline-primary btn-custom">
<?php
echo e($subcode->subcode);
?>
</button>
</a>
#endforeach
</div>
It generates the buttons perfectly. The buttons for one user are not visible to another, since I'm using PID constraint in a query (['PID','=', auth()->user()->PID]).
Pass the passcodes array to view:
$subcodes = []; // Array retrieved from DB
return view('subcode', compact('subcodes'));
And in subcode.blade.php, loop through each subcode:
<div class="grid2">
#foreach($subcodes as $subcode)
<a href="{{ url('/subcode/' . $subcode->subcode) }}">
<button class="btn btn-outline-primary btn-custom-outline-primary btn-custom">SUBCODE {{ $subcode->subcode }}</button>
</a>
#endforeach
</div>
You can loop your codes to create buttons. Something like this (it's for "blade" template engine):
<div class="grid2">
#foreach ($subcodes as $subcode)
{{ $subcode->subcode }}</button>
#endforeach
</div>
Since you're using PID constrain in a query (['PID','=', auth()->user()->PID]), you'll get buttons for that specific PID. So there's no problem.
I have included a couple of files.
my home.blade.php has the following:
#include('includes.header')
my header.blade.php in includes folder has the following
#include('elements.pendingTasksLi', array('tasks'=>$tasks))
and my elements/pendingTasksLi.php file has the following
#foreach ($tasks as $task)
<li>
<a class="todo-actions" href="javascript:void(0)">
<i class="fa fa-square-o"></i>
<span class="desc" style="opacity: 1; text-decoration: none;">{{{$task\['title'\]}}}</span>
<span class="label label-danger" style="opacity: 1;"> {{{$task\['deadLineTime'\]}}}</span>
</a>
</li>
#endforeach
This code in the pendingTakstsLi file is never executed as a loop but only as a simple text.
This is what the output looks like...
#foreach ($tasks as $task)
{{{$task['title']}}} {{{$task['deadLineTime']}}}
#endforeach
I am not sure what to do... Please advise...

You mentioned that your "pendingTasksLi" view ends in ".php" and not ".blade.php" which would prevent it from being parsed as a blade view.
I had the same problem and as mentioned above you forgot the .blade before the .php
If you want to use expressions like this: {{ $variable}} and want them to be parsed you always have to add .blade in the name pefore the .php extension of the file.
