i have an index pages with a link_to:
<h1> User:</h1>
#foreach ($user as $user)
{{link_to("/users/{$user->username}",$user->username)}}
#endforeach
then i have a route:
Route::get('/users/{{$username}}', function($username){
return View::make('show')->with('username',$username);
});
Now, if i understand clear, i am passing username as parameter to function, and username is my url, now if i pass parameter to my show view,
<body>
<div>
<h1> User:</h1>
{{$username}}
</div>
</body>
</html>
I should be able to see it in my page. Where i am wrong? I can't take a parameter from the url when i use get?
Why i need to do:
Route::get('/users/{{$username}}', function($username){
$user=User::whereUsername($username)->fist();
return View::make('show')->with('username',$user);
});
Your route is wrong, this is the correct one:
Route::get('/users/{username}', function($username){
$user=User::whereUsername($username)->fist();
return View::make('show')->with('user',$user);
});
It's just
/users/{username}
and not
/users/{{$username}}
Also, you view will receive an user object, so you have to:
<div>
<h1> User:</h1>
{{$user->username}}
</div>
EDIT
In Laravel there are 2 kind {}:
1) In views you have to use {{}} or {{{}}} (escaped version). Inside them you put PHP code:
{{$variable}}
{{ isset($variable) ? $variable : 'default value' }}
2) In routes, you just use {} and inside it it's not PHP, just a route parameter name, without $:
/user/{name}
/user/{id?} (in this case id is optional, might or might not be send)

I have a simple controller function that fetch all records from db. but when i am trying to show all these records it show nothing. In fact it shows me hard coded foreach loop like this.
#foreach ($compactData as $value) {{ $value->Name }} #endforeach
this is my contoller function.
public function showallProducts()
{
$productstock = Product::all()->stocks;
$productoldprice = Product::all()->OldPrices;
$productcurrentprice = Product::all()->CurrentPrice;
$compactData=array('productstock', 'productoldprice', 'productcurrentprice');
return view('welcome', compact($compactData));
}
this is my view
<!doctype html>
<html lang="{{ app()->getLocale() }}">
<head>
</head>
<body>
<div class="flex-center position-ref full-height">
<div class="content">
<div class="title m-b-md">
Laravel
</div>
<div class="title m-b-md">
All products
</div>
<table>
<tbody>
#foreach ($compactData as $value)
{{ $value->Name }}
#endforeach
</tbody>
</table>
</div>
</div>
</body>
why it is behaving like this. any solution?? I am using phpstorm version 17. Is their any setting issue to run project because what ever project I ran it gives me the only page which i ran with only html?
My route is.
Route::get('/', function () {
$action = 'showallProducts';
return App::make('ProductController')->$action();
});
Have you checked your $compactData variable? Please dd($compactData) to see what it contains.
Problem 1
You are accessing a relational property as a property of Eloquent collection, like this:
Product::all()->stocks
which is not correct. Because the Collection object doesn't have the property stocks but yes the Product object might have a stocks property. Please read the Laravel documentation about Collection.
Problem 2
$compactData = array('productstock', 'productoldprice', 'productcurrentprice');
This line creating an array of 4 string, plain string not variable. So, your $compactData is containing an array of 4 string. If you want to have a variable with associative array then you need to do the following:
$compactData = compact('productstock', 'productoldprice', 'productcurrentprice');
Problem 3
return view('welcome', compact($compactData));
Here you are trying to pass the $compactDate to the welcome view but unfortunately compact() function doesn't accept variable but the string name of that variable as I have written in Problem 2. So, it should be:
return view('welcome', compact('compactData'));
Problem 4
Finally, in the blade you are accessing each element of the $compactData data variable and print them as string which might be an object.
You most likely have a problem with your web server.
Try to use Laravel Valet as development environnement.
Edit : I found this : Valet for Windows
I think you didn't mention the blade in the name of the view file by which it is saved. So change the name of the file by which it is save to something like:
filename.blade.php
and try again.
Explanation:
#foreach ($compactData as $value) this is the syntax of blade template engine, and to parse and excute it, you have to mention the blade extension in the name.
I am getting stuck on this problem, I don't know hot to encrypt the URL for search in Laravel 5.5... the result like this :
localhost:8000/Akademik/Mahasiswa?cari=some_keyword
but I want like this :
localhost:8000/Akademik/Mahasiswa?cari=some_encrypted_keyword
like :
localhost:8000/Akademik/Mahasiswa?cari=Kas6F8ajhasdhhfbdgshek
this my MahasiswaController.php
public function index(Request $request)
{
if ($request->get('cari') == null) {
$datas = Mahasiswa::paginate(10);
return view('Akademik.Mahasiswa.mahasiswaIndex', compact('datas'))->with('no',($request->input('page',1)- 1)*10);
} else {
$cari = $request->get('cari');
$datas = Mahasiswa::where('nama','LIKE','%'.$cari.'%')->paginate(10);
return view('Akademik.Mahasiswa.mahasiswaIndex', compact('datas'))->with('no',($request->input('page',1)- 1)*10);
}
}
This my route/web.php
Route::Resource('Akademik/Mahasiswa','Akademik\Mahasiswa\MahasiswaController');
and This my mahasiswaIndex.blade.php (search form)
<div class="col s4 m6 right">
{{ Form::open(array('url' => 'Akademik/Mahasiswa','method' => 'get')) }}
<div class="row">
<div class="input-field col s12">
{{ Form::text('cari',null,['id' => 'cari','class' => 'col s12']) }}
<label for="cari">Cari</label>
</div>
</div>
{{ Form::close() }}
</div>
if you want to encrypt your input field. you must do in javascript/jquery AJAX before Sending the keyword to url result. let assume you have controller and route to make encryption like this :
localhost:8000/Akademik/encrypt
after that, you will get the keyword encrypted on var some_encrypted_keyword then send again via Ajax GET to url :
localhost:8000/Akademik/Mahasiswa?cari=some_encrypted_keyword
ask me anything. hope this is solve your problem
Are you sure it is actually what you need? For security considerations HTTPS protocol is used, which encrypts all the communication between client side and the server. If you simply want to hide raw data from your browser address bar, you might you POST method instead of GET.
You can encrypt your url parameter and decrypt it in your controller. You can try this:
In your view: Suppose your parameter is cari or more parameter you can encrypt.
<?php
$parameter =[
'cari' => (value of input field),
];
$parameter= Crypt::encrypt($parameter);
?>
a link
Your route will be:
Route::get('/url/{parameter}', 'YourController#methodName');
In your controller, You can decrypt your parameter:
public function methodName($cari){
$data = Crypt::decrypt($cari);
}
You must be use Crypt namespace in your top of controller as
use Illuminate\Support\Facades\Crypt;
Note: You can encrypt url parameter with Crypt::encrypt($parameter) and decrypt with Crypt::decrypt($parameter)
Hi I am trying to get the content within a div element that also happens to be within a form into my controller. I dont want to use ajax. How may I get that done ?
<div id="editorcontents" name="editorcontents">
</div>
Then in controller
Use Input;
$content = Input::get('editorcontents');
In your controller, do something like this. Look up the correct way in the docs (https://laravel.com/docs/5.4/eloquent#retrieving-models). For example, if you want ALL input, you would do Input::all();, instead of Input::where('editorcontents')->get();
public function index() {
$content = Input::where('editorcontents')->get();
return view('your_view.blade.file', compact('content'));
}
Then in your view your would now have $content, that you passed from your controller.
start of by looking at it, add this at top of your view: {{ dd($content) }}. This will die dump $content.
Go ahead and remove that line and do something like (docs here https://laravel.com/docs/5.4/blade#loops):
<div id="editorcontents" name="editorcontents">
#forelse ($content as $value)
<li>{{ $value->body }}</li>
#empty
<p>No content</p>
#endforelse
</div>
I got value from database and then i need to set those value to textbox. I have created a controller file with the method name of edit look like below
userdata.blade.php:
public function edit($id)
{
echo "You have clicked edit link".$name;
$editdata = DB::table('newuser')->where('Id','=',$id)->get();
return View::make('editdata',array('list' => $editdata));
}
I have passed array of value as parameter to the view file.now i need to diaplay the value of name to textbox.how to do that in html page using laravel. My html page look like below
editdata.blade.php:
<html>
<head></head>
<body>
<div>
{{Form::open(array('url' => 'login', 'method' => 'post'))}}
{{Form::label('name','Name',array('id'=>'label-name'))}}
{{Form::text('name',{{$list->Name}}}}
{{ Form::close() }}
</div>
</body>
</html>
can anyone tell me that what mistake i did.Thanks in advance
Just remove the curly brackets, you are already "inside" PHP code and don't need them:
{{ Form::text('name',$list->Name) }}
Also you get a collection from your controller you probably want to do:
$editdata = DB::table('newuser')->where('Id','=',$id)->first();
Or even:
$editdata = DB::table('newuser')->find($id);
get() returns a collection (multiple rows) and not the model itself. You can use User::find($id) which gives you direct access to the model with the specified Id.
When not using eloquent just replace get() with first()
Is it possible to check into a blade view if #yield have content or not?
I am trying to assign the page titles in the views:
#section("title", "hi world")
So I would like to check in the main layout view... something like:
<title> Sitename.com {{ #yield('title') ? ' - '.#yield('title') : '' }} </title>
For those looking on it now (2018+), you can use :
#hasSection('name')
#yield('name')
#endif
See : https://laravel.com/docs/5.6/blade#control-structures
In Laravel 5 we now have a hasSection method we can call on a View facade.
You can use View::hasSection to check if #yeild is empty or not:
<title>
#if(View::hasSection('title'))
#yield('title')
#else
Static Website Title Here
#endif
</title>
This conditional is checking if a section with the name of title was set in our view.
Tip: I see a lot of new artisans set up their title sections like this:
#section('title')
Your Title Here
#stop
but you can simplify this by just passing in a default value as the second argument:
#section('title', 'Your Title Here')
The hasSectionmethod was added April 15, 2015.
There is probably a prettier way to do this. But this does the trick.
#if (trim($__env->yieldContent('title')))
<h1>#yield('title')</h1>
#endif
Given from the docs:
#yield('section', 'Default Content');
Type in your main layout e.g. "app.blade.php", "main.blade.php", or "master.blade.php"
<title>{{ config('app.name') }} - #yield('title', 'Otherwise, DEFAULT here')</title>
And in the specific view page (blade file) type as follows:
#section('title')
My custom title for a specific page
#endsection
#hasSection('content')
#yield('content')
#else
\\Something else
#endif
see "Section Directives" in If Statements - Laravel docs
You can simply check if the section exists:
if (isset($__env->getSections()['title'])) {
#yield('title');
}
And you can even go a step further and pack this little piece of code into a Blade extension: http://laravel.com/docs/templates#extending-blade
Complete simple answer
<title> Sitename.com #hasSection('title') - #yield('title') #endif </title>
I have a similar problem with the solution:
#section('bar', '')
#hasSection('bar')
<div>#yield('bar')</div>
#endif
//Output
<div></div>
The result will be the empty <div></div>
Now, my suggestion, to fix this, is
#if (View::hasSection('bar') && !empty(View::yieldContent('bar')))
<div>#yield('bar')</div>
#endif
New in Laravel 7.x -- sectionMissing():
#hasSection('name')
#yield('name')
#else
#yield('alternative')
#endif
Check if section is missing:
#sectionMissing('name')
#yield('alternative')
#endif
#if (View::hasSection('my_section'))
<!--Do something-->
#endif
Use View::hasSection to check if a section is defined and View::getSection to get the section contents without using the #yield Blade directive.
<title>{{ View::hasSection('title') ? View::getSection('title') . ' - App Name' : 'App Name' }}</title>
I don't think you can, but you have options, like using a view composer to always provide a $title to your views:
View::composer('*', function($view)
{
$title = Config::get('app.title');
$view->with('title', $title ? " - $title" : '');
});
why not pass the title as a variable View::make('home')->with('title', 'Your Title') this will make your title available in $title
Can you not do:
layout.blade.php
<title> Sitename.com #section("title") Default #show </title>
And in subtemplate.blade.php:
#extends("layout")
#section("title") My new title #stop
The way to check is to not use the shortcut '#' but to use the long form: Section.
<?php
$title = Section::yield('title');
if(empty($title))
{
$title = 'EMPTY';
}
echo '<h1>' . $title . '</h1>';
?>
Building on Collin Jame's answer, if it is not obvious, I would recommend something like this:
<title>
{{ Config::get('site.title') }}
#if (trim($__env->yieldContent('title')))
- #yield('title')
#endif
</title>
Sometimes you have an enclosing code, which you only want to have included in that section is not empty. For this problem I just found this solution:
#if (filled(View::yieldContent('sub-title')))
<h2>#yield('sub-title')</h2>
#endif
The title H2 gets only displayed it the section really contains any value. Otherwise it won't be printed...
