I want to check for $house->category.
Depending on the category i want to send parameters with the #extends() functions.
I can't get it to work. When I use something like:
#if($house->category == 1)
#extends('templates.main')
#else
#extends('templates.main', ['logo' => 'img/logo/logo_red_white_text.png', 'favicon' => 'img/favicon/favicon_red.ico'])
#endif
The template is injected twice.
use "#include" instead of extends, and if it's being injected two times you can prevent that by handling that logic on the controller, make a method "checkHouseCategory" or something like that, to check if $house->category == 1, then just send a boolean to the template.
The problem is that you cannot pass parameters in #extends function.
What you can do is to move the view partial to separated file and then #include it in i.e. main file with the above condition. So this will looks like:
Partial view with #extends I will name: example.blade.php
Then in the main view partial:
#if($house->category == 1)
#include('example')
#else
#extends('example', ['logo' => 'img/logo/logo_red_white_text.png', 'favicon' => 'img/favicon/favicon_red.ico'])
#endif

This is probably something simple, but it's doing my head in.
So, my layout blade template has this:
#include('layouts.partials.sidebar')
{{ $slot }}
#include('layouts.partials.footer')
#include('layouts.partials.scripts')
I create a view which loads a template. This I assume gets parsed in $slot.
return view('request', [
'boo' => 'Hoo'
]);
No problems, the page loads and the variable 'boo' is accessible as {{ $boo }} in the 'requests' template.
But my question is, how can I pass the 'boo' variable to an included file in the layout file? In this case the following:
#include('layouts.partials.scripts')
So, in 'layouts.partials.scripts' how can I access {{ $boo }}? At the moment I just get an undefined index error.
Thank you very much for the help.
#include('layouts.partials.scripts', ['boo' => 'Hoo'])

If you have a partial like a nav, header, or sidebar, part of the master layout from which you are composing other views. It requires data that doesn't change from one view to another, like navigation links. Then, instead of passing the data from each controller method, you can define a view composer in a service provider's boot() method:
Service Provider's boot method
public function boot()
{
View::composer('layouts.partials.sidebar', function ($view) {
//$links = get the data for links
return $view->with('links', $links);
});
}

do you ever use PHP built-in function inside blade yield ?
For example can we do something like this :
// master layouts
#yield(ucwords('title'))
// view
#section('title', $title)
Note: $title is from controller
I've already try the first example, but it doesn't work. It doesn't output the $title on my view. Right now I am using this in all of my views
// master layouts
#yield('title')
// view 1
#section('title', ucwords($title))
// view 2
#section('title', ucwords($title))
// view 3
#section('title', ucwords($title))
But I think on second example, I'm not DRY my code because I always repeating the ucwords() on each my view. Can we using it on master layout right on yield declaration?
Thank you guys, have a nice work!
You can make your own blade directive for example if you want to make a #ucfirst() then do something like this in AppServiceProvider .
Blade::directive('ucfirst', function ($expression) {
return ucfirst($expression);
});
Past this into boot()
or on each section() you can extend the main layout #section('title', ucwords($title)) or make the helpers like i mentioned above
as you mentioned above you can use yield()
#yield('title',ucwords(strtolower('Your title')))
I am trying to retrieve data from database and check if the data is empty or not. What problem I am facing is that html is showing even if the data is empty. I want to ignore the html tag like example ul li. Here how i tried is like
#if(!empty($jobseekers->skill_1))
<li> My Skill is : {{ \App\skill::where('id',$jobseekers->skill_1)->pluck('name')->first() }}</li><br/>
#endif
I want to ignore "My Skill is " if the data is empty. I don't want to show anything.
When using ->get() you can't simply use any of the below:
if (empty($jobseekers->skill_1)) { }
if (!$jobseekers->skill_1) { }
if ($jobseekers->skill_1) { }
But, When you are getting data with first() method, You can simply use all above methods.
Because if you dd($jobseekers->skill_1); you'll notice an instance of Illuminate\Support\Collection is always returned, even when there are no results.
I think you are using !empty() on data with ->get() method which will always return true even data is empty. You need to use other way.
To determine if there are any results you can do any of the following:
if (!$jobseekers->skill_1->isEmpty()) { }
if ($jobseekers->skill_1->count()) { }
if (count($jobseekers->skill_1)) { }
If you get $jobseekers with get() method you can not use empty($jobseekers )
instead of empty you can use other conditions :
#if($jobseekers->skill_1 != '')
in this condition you check skill_1 as empty string
also
#if($jobseekers->skill_1)
and etc
replace your code with below code and check it:
#if($jobseekers->skill_1 != '')
<li> My Skill is : {{ \App\skill::where('id',$jobseekers->skill_1)-pluck('name')->first() }}</li><br/>
#endif
you should use isset()
#if(isset($jobseekers->skill_1))
<li> My Skill is : {{ \App\skill::where('id',$jobseekers->skill_1)->pluck('name')->first() }}</li><br/>
#endif
you can use count method
#if(count($jobseekers->skill_1)>0)
<li> My Skill is : {{ \App\skill::where('id',$jobseekers->skill_1)-pluck('name')->first() }}</li><br/>
#endif
#if(count($data)>0)
//write your code which you want to show if data is available
#endif
I have a menu partial, that includes a input search bar. But i don't want the search bar to be visibel on all pages, only for two specific uri´s. Is there a way to remove that include in blade?
Currently it looks like this:
all
nes
snes
#include('partials._search')
I was thinking something like
all
nes
snes
#if($url)
#include('partials._search')
#endif
Use is() method:
#if (request()->is($url))
#include('partials._search')
#endif
Or if you know route name:
#if (request()->route()->getName() === $routeName)
#include('partials._search')
#endif
To retrieve URL from the blade template, use {{ Request::url() }}.
This will output something like http://example.dev/articles
To retrieve path, use {{ Request::path() }}
Using the above example, this will output articles.
From what I understand:
View::share('foo','bar');
Will make $foo available in all views.
However, is it correct to say View::share() can be used only in the __construct()?
Because from outside __construct() I can't make it to work.
View::share should be available anywhere within your application. A common place that it is used is in view composers, but it should be usable within a route or wherever you need it.
Yes, adding:
View::share('foo','bar');
in your routes.php file will make $foo (with a value of 'bar') available in all views. This is especially useful for something like Twitter Bootstrap's "active" navigation classes. For example, you could do:
View::share('navactive', '');
to make sure the navactive variable is set in all views (and thus won't throw errors) and then when you are making views (in your controller, for example), you could pass:
return View::make('one')->with('navactive', 'one');
and then in your view (preferably some bootstrappy blade template) you can do the following:
<ul class="nav">
#if ( Auth::user() )
<li #if ($navactive === 'one') class="active" #endif>One</li>
<li #if ($navactive === 'three') class="active" #endif>Three</li>
<li #if ($navactive === 'five') class="active" #endif>Five</li>
#endif
</ul>
Basically if you want to share the variables through all view, you might first want to create a base route(E.x.:internalController.php) as a parent class then extend other controllers as a child of it(E.x:childController.php).
And yeah you will most likely set the view::share('foo', $bar) in the __constructor() of the internalController.php, since it lunches whenever the class is initialized, this way the parent class will serve the variable values to the child classes.
