Problems with blade echo - php

Sometimes blade echo doesn't print and I don't know why.
With this code visits are not printed
#extends('layouts/base', ['title' => "$url->new"])
#section('content')
<h1>Link Shortened !</h1>
{{ $url->new }}
<h3>visits {{ $url->visitsĀ }}</h3>
#endsection
With this code (removing the space after visits) the number of visits is printed
#extends('layouts/base', ['title' => "$url->new"])
#section('content')
<h1>Link Shortened !</h1>
{{ $url->new }}
<h3>visits {{ $url->visits}}</h3>
#endsection

It should work when you replace "$url->new" to $url->new in the #extends lines.

Laravel 5 misroute?

I'll copy the relevant code and then i'll explain the problem.
routes.php
get('/movies/create', 'MovieController#create');
Moviecontroller.php
public function create()
{
return view('movies.create');
}
master.blade.php
<html>
<head>
<title>Laravel</title>
</head>
<body>
#yield('content')
</body>
</html>
edit.blade.php
#extends('master')
#section('content')
<h1>Edit {{ $movie->name }}</h1>
{!! Form::model($movie, ['url' => '/movies/' . $movie->id, 'method' => 'PATCH']) !!}
{!! Form::text('name') !!}
{!! Form::text('director') !!}
{!! Form::textarea('description') !!}
{!! Form::text('rating') !!}
{!! Form::submit('Update movie') !!}
{!! Form::close() !!}
#stop
show.blade.php
#extends('master')
#section('content')
<h1>{{ $movie->name }}</h1>
<h4>Director: {{ $movie->director }}</h4>
<h4>Rating: {{ $movie->rating }}</h4>
<p>Description: {{ $movie->description }}</p>
{!! link_to('/movies/' . $movie->id . '/edit', 'Edit') !!}
#stop
so i have this code, but when i go to /movies/create in the browser, it's trying to open show.blade.html, which, of course, will throw an exception ($movie does not exist). Why does that happen?
You probably have a conflicting route above the one you showed, something like this:
get('/movies/{movie}', 'MovieController#show');
get('/movies/create', 'MovieController#create');
So when you go to yoursite.com/movies/create in your browser, the first route is triggered, and the controller opens show.blade.php - but there is no movie for it to show yet.
If you move them the other way around, the create method will work as intended, and you'll still be able to show existing movies:
get('/movies/create', 'MovieController#create');
get('/movies/{movie}', 'MovieController#show');
best way:
php artisan make:controller MovieController
and define route
Route::resource('movies', 'MovieController');
//available routes
Verb Path
GET /movies
GET /movies/create
POST /movies
GET /movies/{id}
GET /movies/{id}/edit
PUT/PATCH /movies/{id}
DELETE /movies/{id}

Update Database with Laravel

I am trying to update information in my database with Laravel. Not sure what I am doing wrong but I can't seem to find where the problem is. Here is the code for my edit page (This is the page where I would edit information taken from my DB).
{{ Form::open(['url'=>'portfolio/update']) }}
<div>
{{ Form::label('portfolio_title', 'Portfolio Title:') }}
{{ Form::text('portfolio_title',$work->portfolio_title) }}
{{ $errors->first('portfolio_title','<span class="error">:message</span>') }}
</div>
<div>
{{ Form::label('portfolio_description', 'Portfolio Description') }}<br>
{{ Form::textarea('portfolio_description', $work->portfolio_description, ['size' => '50x5']) }}
{{ $errors->first('portfolio_description','<span class="error">:message</span>') }}
</div>
<div>
{{ Form::label('portfolio_content', 'Portfolio Content') }}<br>
{{ Form::textarea('portfolio_content', $work->portfolio_content, ['size' => '50x5']) }}
{{ $errors->first('portfolio_content','<span class="error">:message</span>') }}
</div>
{{ Form::hidden('id',$work->id) }}
<div>
{{ Form::submit('Update Work') }}
</div>
{{ Form::close() }}
I have a controller called PortfolioController that will save info to database and what not.
public function edit($work_title){
$work = Portfolio::wherePortfolio_title($work_title)->first();
return View::make('portfolio/edit', ['work' => $work]);
}
public function update(){
$id = Input::get('id');
$input = Input::except('id');
if( !$this->portfolio->fill($input)->isValid()){
return Redirect::back()->withInput()->withErrors($this->portfolio->errors);
}
$work = Portfolio::find($id);
$work->portfolio_title = Input::get('id');
$work->save();
}
Here is my route that I am working with:
Route::resource('portfolio','PortfolioController');
Route::post('portfolio/update','PortfolioController#update');
I am able to get the form populated with the correct information but when i change something like the title and click update, the page reloads but does not save in the DB. Sometimes I will get an MethodNotAllowedHttpException error. This has been pretty frustrating for me so any help will be greatly appreciated.
Why don't you just actually use your resource route?
First, remove the portfolio/update route. You don't need it.
Then change your Form::open to this:
{{ Form::open(['route' => ['portfolio.update', $work->portfolio_title], 'method' => 'put']) }}
This way you target the update method in your RESTful controller.
Finally change that to use the portfolio_title as identifier and you should be able to remove the hidden id field from your form.
public function update($work_title){}
Please take a look at:

Opening a form

Directing through form

Im a beginner with laravel. Im following the laracasts tutorial and Im stuck at the part where you access another page with a form by:
{{ Form::open(['url' => 'created']) }}
for example.
Now that leads me to the right url but it gives me
Whoops, looks like something went wrong.
As soon as I type the link manually it works normally.
This is the code of the page where it directs to:
controller:
public function created()
{
return 'hello';
}
Routes:
Route::get('created', 'TestController#created');
View:
#extends('layout')
#section('content')
<h1> Test </h1>
#stop
This is the form of the 1st page:
#extends('layout')
#section('content')
<h1>Create New User</h1>
{{ Form::open(['url' => 'created']) }}
<div>
{{ Form::label('email', 'E-mail:')}}
{{ Form::text('email')}}
</div>
<div>
{{ Form::label('password', 'Password:')}}
{{ Form::password('password')}}
</div>
<div>
{{ Form::submit('Create')}}
</div>
{{ Form::close()}}
#stop
What is going wrong here?
Form open by default links to a post method so what you need is either a post route or a get method. Following should work:
{{ Form::open(['url' => 'created']) }}
// Insert your fields/codes here
{{ Form::close() }}
//Change route method to post
Route::post('created', 'TestController#created');
Please read the documentation here for more details.

Blade templating (Laravel) overwrite issues

I have a "master" layout that has a section: #yield('other-scripts')
I use this master template in another view (especie.blade.php):
#extends('layouts.master')
#include('layouts.editarEspecie')
#section('other-scripts')
{{ HTML::script('js/lightbox.js') }}
#stop
Inside layouts.editarEspecie, #section('other-scripts') is also overwritten:
#section('other-scripts')
{{ HTML::script('js/chosen.jquery.js') }}
{{ HTML::script('js/chosenScriptModal.js') }}
{{ HTML::script('js/scripts.js') }}
#stop
The problem is that #include('layouts.editarEspecie') goes first, so #section('other-scripts') never adds the part inside especie.blade.php.
What can I do so that both part are added and it ends like this?
{{ HTML::script('js/chosen.jquery.js') }}
{{ HTML::script('js/chosenScriptModal.js') }}
{{ HTML::script('js/scripts.js') }}
{{ HTML::script('js/lightbox.js') }}
P.S.: I do this because lightbox.js is always necessary, but chosen.jquery.js, chosenScriptModal.js, scripts.js may not always be needed.
Inside layouts.editarEspecie dont have a "section" - just have this:
{{ HTML::script('js/chosen.jquery.js') }}
{{ HTML::script('js/chosenScriptModal.js') }}
{{ HTML::script('js/scripts.js') }}
Then those 3 lines will always be included.
The thing is, I donĀ“t want those 3 lines to always go inside
layouts.editarEspecie, just when certain conditions are met (not shown
here)
ummmmm.. i know its like the fastest thing ever but you can always PHP if it
<?php
if (condition)
{
?>
{{ script here}}
<?php
}
else
{}
?>
Sorry for lazy explanation but i am sure you get the hint

How to tackle variables that may not be set when using blade template engine to build forms

Ok, so a long title, but apologies, he only way to describe it without getting the wrong kind of answer.
So, the scenario....
I am creating a site which has a search form of sorts in the header, and therefore on every page. I would like it to retain its previous variables when being used for user convenience, for my convenience I have built the form into the default layout, to save recreating many instances of it.
default.blade.php (Heres the form, with unnecessary markup removed)
{{ Form::open(array('url' => '/search')) }}
{{ Form::select('model', Photo::getAvailableModels(true), $model) }}
{{ Form::select('colour', Photo::getAvailableColours(true), $colour) }}
{{ Form::submit('Go') }}
{{ Form::close() }}
The $model & $colour are variables I am capturing during the post. The problem is, I am getting unset variable errors from Blade on any pages where the user hasn't posted to, so I am literally having to preset them in almost every route or controller across my entire site, just to prevent the errors.
In essence, the system works fine as long as the user is posting, if someone visits the site using a direct link its basically useless.
Obviously I can not have the search form be set to the previously searched results, but that would be bad practice from a usability point of view.
Am I missing something here, surely there has to be a simple solution to this. Thanks for any help.
Create a view composer for your highly used variables:
View::composer(['store.index', 'products.*'], function($view)
{
$model = Input::get('model') ?: 'modelX';
$colour = Input::get('colour') ?: 'colourY';
$view->with('model', $model);
$view->with('colour', $colour);
});
Laravel will send those variables to your views automatically, every time someone hit one of them.
You can put that in your routes file, filters file or, like, me, create a app/composers.php and load by adding
require app_path().'/composers.php';
To your app/start/global.php.
You can check whether variables are set or not with PHP isset():
{{ Form::open(array('url' => '/search')) }}
#if (isset($model) && isset($colour))
{{ Form::select('model', Photo::getAvailableModels(true), $model) }}
{{ Form::select('colour', Photo::getAvailableColours(true), $colour) }}
#else
{{ Form::select('model', Photo::getAvailableModels(true)) }}
{{ Form::select('colour', Photo::getAvailableColours(true)) }}
#endif
{{ Form::submit('Go') }}
{{ Form::close() }}
Or, if your form fields are optional and you need to check separately:
{{ Form::open(array('url' => '/search')) }}
#if (isset($model))
{{ Form::select('model', Photo::getAvailableModels(true), $model) }}
#else
{{ Form::select('model', Photo::getAvailableModels(true)) }}
#endif
#if (isset($colour))
{{ Form::select('colour', Photo::getAvailableColours(true), $colour) }}
#else
{{ Form::select('colour', Photo::getAvailableColours(true)) }}
#endif
{{ Form::submit('Go') }}
{{ Form::close() }}
