Use Carbon Model on laravel blade the path error - laravel

when I use the carbon on my blade
localhost:8000/todo.blade.php
I use
{{ Carbon::parse($chunk->time)->diffForHumans()}}
But when I use the cabon on my blade
localhost:8000/todo/todolist.blade.php
I must use
{{ Carbon\Carbon::parse($chunk->time)->diffForHumans()}}
why the url is different and how can I use the same code on the any location
just like
{{ Carbon::parse($chunk->time)->diffForHumans()}}
Or can I use some code like asset()??
{{ asset(Carbon::parse($chunk->time)->diffForHumans())}}

If you want use {{ Carbon::parse($chunk->time)->diffForHumans()}} in any location you need register Class Aliases. Go to config\app.php and add to existing aliases new one:
'aliases' => [
//...other aliases
'Carbon' => \Carbon\Carbon::class
];
Now you can use Carbon instead of \Carbon\Carbon everywhere.

What it is the solution for this problem Laravel Action

Action App\Http\Controllers\AdminController#dbTanger not defined.
And this is My AdminController
public function dbTanger() {
$data = Db::table('ressos')
->where('secteur','Services')
->get();
return view('backend.layouts.admin.typeFilterTanger',compact('data','pagi'));
}
And this is the view
<div class="Filter">
<p>Filter Using Ville</p>
Tanger-Asilah
</div>
so if anyone can help me please
and thank you all
Since Laravel 9, the default Controller namespace has not been included in the RouteServiceProvider so you need to be explicit about where to locate controllers (or add the default namespace to your RouteServiceProvider).
What you can do is the following:
{{ action('\App\Http\Controllers\AdminController#dbTanger') }}
However, I would recommend using the route helper in conjunction with named routes as this is easier to manage should files change or move location in the future.
Route::get('/admin/dbTanger', [AdminController::class, 'dbTanger'])->name('admin.dbTanger');
Then use it as follows:
{{ route('admin.dbTanger') }}
The outcome is the same, just easier to manage and maintain long-term.
That error would mean you didn't define a route to this action so there is nothing in the route collection to be found for that action.
Define a route for this action and you would be able to use that action helper to create a URL to a route that uses this action.

What's the equivalent function of i18n t() function in Laravel?

In i18next, people are defining t() function as translation utility, vue has vue-i18n, react i18n also has such thing.
Here comes my question, what's the equivalent t() function in Laravel?
In Laravel you can use __ helper function for the same.
As per Laravel documentation:
You may retrieve lines from language files using the __ helper function. The __ method accepts the file and key of the translation string as its first argument. For example, let's retrieve the welcome translation string from the resources/lang/messages.php language file:
echo __('messages.welcome');
echo __('I love programming.');
If you are using the Blade templating engine, you may use the {{ }} syntax to echo the translation string or use the #lang directive:
{{ __('messages.welcome') }}
#lang('messages.welcome')
Reference:
Laravel -> Localization -> Retrieving Translation Strings
trans('messages.welcome'), trans_choice('messages.apples', 10), and #lang('messages.welcome')
TO display in the blade wrap those in {{ }} like {{ trans('messages.welcome') }}
To display html contained in them in blade use {!! !!} like {!! trans('messages.welcome') !!}

How to add helper class function in twig template with laravel

in blade template I have used like:
{{ Helper::getName() }}
But how it is used with twig template?
If you are using laravel-twigbridge you can use helpers from default Extensions, e.g:
{{ form_open(...) }}
instead of
{{ Form::open(...) }}
See docs

Laravel 4 Javascript Link using {{Html}}

Is there any Laravel4 Html() function or way to add a disabled link. Of course I could create the <a> tag directly, though I'd prefer to be consistent.
ie:
{{ Html::link('javascript:;','Delete',array('id'=>"deletebt")) }}
You must use link_to, for example :
link_to('link', 'title', array('id' => 'MyId'));

How to var_dump variables in twig templates?

View layer pattern where you only present what you have been given is fine and all, but how do you know what is available? Is there a "list all defined variables" functionality in TWIG? Is there a way to dump a variable?
The solution I found by searching for it was to define a function where I can use my existing php debug tools by injecting a function, but all references I have found to that includes these nice two lines of code, but nowhere is it specified where to place them. Going by the fact that they need a $loader variable defined, I tried /app/config/autoload.php but the $loader there was the wrong kind. Where do I place the php code for adding a twig function?
As of Twig 1.5, the correct answer is to use the dump function. It is fully documented in the Twig documentation. Here is the documentation to enable this inside Symfony.
{{ dump(user) }}
If you are in an environment where you can't use the dump function (ex: opencart), you can try:
{{ my_variable | json_encode(constant('JSON_PRETTY_PRINT')) }}
You can use the debug tag, which is documented here.
{% debug expression.varname %}
Edit: As of Twig 1.5, this has been deprecated and replaced with the new dump function (note, it's now a function and no longer a tag). See also: The accepted answer above.
So I got it working, partly a bit hackish:
Set twig: debug: 1 in app/config/config.yml
Add this to config_dev.yml
services:
debug.twig.extension:
class: Twig_Extensions_Extension_Debug
tags: [{ name: 'twig.extension' }]
sudo rm -fr app/cache/dev
To use my own debug function instead of print_r(), I opened vendor/twig-extensions/lib/Twig/Extensions/Node/Debug.php and changed print_r( to d(
PS. I would still like to know how/where to grab the $twig environment to add filters and extensions.
If you are using Twig in your application as a component you can do this:
$twig = new Twig_Environment($loader, array(
'autoescape' => false
));
$twig->addFilter('var_dump', new Twig_Filter_Function('var_dump'));
Then in your templates:
{{ my_variable | var_dump }}
Dump all custom variables:
<h1>Variables passed to the view:</h1>
{% for key, value in _context %}
{% if key starts with '_' %}
{% else %}
<pre style="background: #eee">{{ key }}</pre>
{{ dump(value) }}
{% endif %}
{% endfor %}
You can use my plugin which will do that for you (an will nicely format the output):
Twig Dump Bar
If you are using Twig as a standalone component here's some example of how to enable debugging as it's unlikely the dump(variable) function will work straight out of the box
Standalone
This was found on the link provided by icode4food
$twig = new Twig_Environment($loader, array(
'debug' => true,
// ...
));
$twig->addExtension(new Twig_Extension_Debug());
Silex
$app->register(new \Silex\Provider\TwigServiceProvider(), array(
'debug' => true,
'twig.path' => __DIR__.'/views'
));
The complete recipe here for quicker reference (note that all the steps are mandatory):
1) when instantiating Twig, pass the debug option
$twig = new Twig_Environment(
$loader, ['debug'=>true, 'cache'=>false, /*other options */]
);
2) add the debug extension
$twig->addExtension(new \Twig_Extension_Debug());
3) Use it like #Hazarapet Tunanyan pointed out
{{ dump(MyVar) }}
or
{{ dump() }}
or
{{ dump(MyObject.MyPropertyName) }}
{{ dump() }} doesn't work for me. PHP chokes. Nesting level too deep I guess.
All you really need to debug Twig templates if you're using a debugger is an extension like this.
Then it's just a matter of setting a breakpoint and calling {{ inspect() }} wherever you need it. You get the same info as with {{ dump() }} but in your debugger.
Since Symfony >= 2.6, there is a nice VarDumper component, but it is not used by Twig's dump() function.
To overwrite it, we can create an extension:
In the following implementation, do not forget to replace namespaces.
Fuz/AppBundle/Resources/config/services.yml
parameters:
# ...
app.twig.debug_extension.class: Fuz\AppBundle\Twig\Extension\DebugExtension
services:
# ...
app.twig.debug_extension:
class: %app.twig.debug_extension.class%
arguments: []
tags:
- { name: twig.extension }
Fuz/AppBundle/Twig/Extension/DebugExtension.php
<?php
namespace Fuz\AppBundle\Twig\Extension;
class DebugExtension extends \Twig_Extension
{
public function getFunctions()
{
return array (
new \Twig_SimpleFunction('dump', array('Symfony\Component\VarDumper\VarDumper', 'dump')),
);
}
public function getName()
{
return 'FuzAppBundle:Debug';
}
}
For debugging Twig templates you can use the debug statement.
There you can set the debug setting explicitely.
You can edit
/vendor/twig/twig/lib/Twig/Extension/Debug.php
and change the var_dump() functions to \Doctrine\Common\Util\Debug::dump()
As most good PHP programmers like to use XDebug to actually step through running code and watch variables change in real-time, using dump() feels like a step back to the bad old days.
That's why I made a Twig Debug extension and put it on Github.
https://github.com/delboy1978uk/twig-debug
composer require delboy1978uk/twig-debug
Then add the extension. If you aren't using Symfony, like this:
<?php
use Del\Twig\DebugExtension;
/** #var $twig Twig_Environment */
$twig->addExtension(new DebugExtension());
If you are, like this in your services YAML config:
twig_debugger:
class: Del\Twig\DebugExtension
tags:
- { name: twig.extension }
Once registered, you can now do this anywhere in a twig template:
{{ breakpoint() }}
Now, you can use XDebug, execution will pause, and you can see all the properties of both the Context and the Environment.
Have fun! :-D
you can use dump function and print it like this
{{ dump(MyVar) }}
but there is one nice thing too, if you don't set any argument to dump function, it will print all variables are available, like
{{ dump() }}
