The blade template engine can be used with codeigniter? - php

The template engine called blade can be used with codeigniter or pure php? I know that it can be used with laravel and I'd like to know if also can be used with any other php framework or with pure php

Blade can be used stand-alone in PHP.
This means you can comfortably use it in CodeIgniter.
https://github.com/PhiloNL/Laravel-Blade
Then again, you will need composer for that.

Alternatively you could use this CodeIgniter Library to simulate Blade: CodeIgniter Slice-Libray
It works pretty like Blade and it was designed directly for CodeIgniter!

For the record and as answer to another post:
I tested many libraries to run blade outside Laravel (that i don't use) and most (with all respect of the coders) are poor hacks of the original library that simply copied and pasted the code and removed some dependencies yet it retains a lot of dependencies of Laravel.
I created an alternative for blade that its free (MIT license, i.e. close source/private code is OK) in a single file and without a single dependency of an external library. You could download the class and start using it, or you could install via composes (composer require eftec/bladeone). So even composer is optional.
https://github.com/EFTEC/BladeOne
https://packagist.org/packages/eftec/bladeone
Its 100% compatible sans the Laravel's own features (extensions).

You can use BladeView library for CI.
NB: I ported this library
class Welcome extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->library("bladeview");
}
public function renderView(){
$data=array(
"name"=>"Jhon",
"age"=>21
);
$this->bladeview->render("test", $data);
}
public function renderString(){
$data=array(
"name"=>"Jhon",
"age"=>21
);
$string="Hello I'm \{{$name}}. My age is \{{$age}}";
$this->bladeview->render($string, $data,false);
}
}
then in view.blade.php you can render like you do in laravel blade.
Hello my name is {{$name}}. My Age is {{$age}}.
Output:
Hello my name is Jhon. My Age is 21.

I have done a full write up here: http://mstd.eu/index.php/2017/03/02/using-the-laravel-blade-templating-engine-in-codeigniter-3/
Basically, include the package with composer (you need to set CI up to use composer), then create a blade instance passing it your view and cache folder like so:
$blade = new BladeInstance(__DIR__ . "/../views", __DIR__ . "/../cache/views");
echo $blade->render("index");

Yii2 $model->_attributes assignment does not work in new version

I inherited a project that was created with Yii2, ver. 2.0.4, with the task to update said project to a more current version of Yii2 (2.0.15) because of the incompatibility of the older one with PHP 7.2+.
I noticed that there is a lot of use of assigning arrays to a model:
$model->_attributes = $array;
With the new version this results in an exception
'yii\base\UnknownPropertyException' with message 'Setting unknown property: app\models\model::_attributes'
For the time being I created a workaround with the following function:
function customSetAttributes(&$model, $array) {
foreach($model->attributeLabels() as $model_key => $model_label) {
if(!isset($array[$model_key])) continue;
$model->$model_key = $array[$model_key];
}
}
Also, the getter function now has a similar issue.
What I would like to know:
Was this type of assignment never intended in the first place (and I just haven't found the previous developer's code that enables it)? I skimmed over the Yii2 changelog but didn't notice anything related.
Is there a way to "salvage" the previous behaviour so I don't have to replace each occurence with my workaround function?
ActiveRecord::$_attributes was always private and never should be used in this way. I guess that previous developer edited framework core files in vendor directory and make this property protected/public.
You may try to emulate this behavior by creating virtual attribute using getter and setter:
public function get_attributes() {
return $this->getAttributes();
}
public function set_attributes($values) {
$this->setAttributes($values, false);
}
But this will not always work and it is more like an ugly hack to make crappy code work. I strongly suggest to fix code to use setAttributes() instead of _attributes.
Also you should compare yii2 package from vendor directory with source from https://github.com/yiisoft/yii2-framework/releases/tag/2.0.4 - you may find more places where core was edited.

Yii2: How to force using fallback MessageFormatter method?

My website is with a hosting provider that has the MessageFormatter class available on the server (Linux, PHP 7.0.27) but it is an old ICU version (4.2.1) that doesn't support my message {number,plural,=0{# available} =1{# available} other{# available}} and gives the error:
Message pattern is invalid: Constructor failed
msgfmt_create: message formatter creation failed: U_ILLEGAL_CHARACTER
...because of the =1 and =2 notation.
I'm not able to make changes to the server so how can I force using the fallback method provided by Yii2 which works just fine?
There is this hacky way you can try.
Copy the yii\i18n\MessageFormatter code to a new file. Name it MessageFormatter.php and place somewhere in your application (but not in vendor folder).
In this new file change the format() method to:
public function format($pattern, $params, $language)
{
$this->_errorCode = 0;
$this->_errorMessage = '';
if ($params === []) {
return $pattern;
}
return $this->fallbackFormat($pattern, $params, $language);
}
Don't change anything else (including namespace).
Now let's use Yii mapping.
Find a place in your application when you can put code that will be run every time in bootstrapping phase. Good place for this is common/config/bootstrap.php if you are using "Advanced Template"-like project.
Add there this line:
Yii::$classMap['yii\i18n\MessageFormatter'] = 'path/to/your/MessageFormatter.php';
Obviously change the path to the one you've chosen. Now Yii autoloader will load this class from your file instead of the original Yii vendor folder (as mentioned in Class Autoloading section of the Guide).
In the modified file MessageFormatter method presence of intl library is never checked so fallback is used as default.
The downside of this trick is that you need to update manually your file every time original Yii file is changed (so almost every time you upgrade Yii version).
Another approach is to configure I18N component in your application to use your custom MessageFormatter where you can extend the original file and just override format() method inside without modifying class map.

Can I use the Blade templating engine outside of Laravel?

i'm want to creating a design pattern and use the "Blade templating engine".
Can I use the Blade templating engine outside of Laravel and use it in my new pattern ?
For the record:
I tested many libraries to run blade outside Laravel (that i don't use) and most are poor hacks of the original library that simply copied and pasted the code and removed some dependencies yet it retains a lot of dependencies of Laravel.
So I created (for a project) an alternative for blade that its free (MIT license, i.e. close source/private code is OK) in a single file and without a single dependency of an external library. You could download the class and start using it, or you could install via composer.
https://github.com/EFTEC/BladeOne
https://packagist.org/packages/eftec/bladeone
It's 100% compatible without the Laravel's own features (extensions).
How it works:
<?php
include "lib/BladeOne/BladeOne.php";
use eftec\bladeone;
$views = __DIR__ . '/views'; // folder where is located the templates
$compiledFolder = __DIR__ . '/compiled';
$blade=new bladeone\BladeOne($views,$compiledFolder);
echo $blade->run("Test.hello", ["name" => "hola mundo"]);
?>
Another alternative is to use twig but I tested it and I don't like it. I like the syntax of Laravel that its close to ASP.NET MVC Razor.
Edit: To this date (July 2018), it's practically the only template system that supports the new features of Blade 5.6 without Laravel. ;-)
You certainly can, there are lots of standalone blade options on packagist, as long as you are comfortable with composer then there should be no issue, this one looks pretty interesting due to having a really high percentage of stars compared to downloads.
Be warned though i have not tried it myself, like you i was looking for a standalone option for my own project and came across it, i will be giving it a real good workout though at sometime in the near future,
Matt Stauffer has created a whole repository showing you how you can use various Illuminate components directly outside of Laravel. I would recommend following his example and looking at his source code.
https://github.com/mattstauffer/Torch
Here is the index.php of using Laravel Views outside of Laravel
https://github.com/mattstauffer/Torch/blob/master/components/view/index.php
You can write a custom wrapper around it so that you can call it like Laravel
use Illuminate\Container\Container;
use Illuminate\Events\Dispatcher;
use Illuminate\Filesystem\Filesystem;
use Illuminate\View\Compilers\BladeCompiler;
use Illuminate\View\Engines\CompilerEngine;
use Illuminate\View\Engines\EngineResolver;
use Illuminate\View\Engines\PhpEngine;
use Illuminate\View\Factory;
use Illuminate\View\FileViewFinder;
function view($viewName, $templateData)
{
// Configuration
// Note that you can set several directories where your templates are located
$pathsToTemplates = [__DIR__ . '/templates'];
$pathToCompiledTemplates = __DIR__ . '/compiled';
// Dependencies
$filesystem = new Filesystem;
$eventDispatcher = new Dispatcher(new Container);
// Create View Factory capable of rendering PHP and Blade templates
$viewResolver = new EngineResolver;
$bladeCompiler = new BladeCompiler($filesystem, $pathToCompiledTemplates);
$viewResolver->register('blade', function () use ($bladeCompiler) {
return new CompilerEngine($bladeCompiler);
});
$viewResolver->register('php', function () {
return new PhpEngine;
});
$viewFinder = new FileViewFinder($filesystem, $pathsToTemplates);
$viewFactory = new Factory($viewResolver, $viewFinder, $eventDispatcher);
// Render template
return $viewFactory->make($viewName, $templateData)->render();
}
You can then call this using the following
view('view.name', ['title' => 'Title', 'text' => 'This is text']);
Yes you can use it where ever you like. Just install one of the the many packages available on composer for it.
If you're interested in integrating it with codeigniter I have a blog post here outlining the process.
Following the above steps should make it obvious how to include it into any framework.

How laravel classes are included?

I want to run custom php code in laravel directly without using any routes or http requests..
I hope I can make it clear, I mean, like those online tools that runs php code by writing php code in browser, and then run it, and view result..
I found this handy project (Run-PHP-Code) to run PHP in browser directly, but I can't use models of my laravel project in PHP code..
How can I include laravel 's environment, so that I can for example:
$tag= new Tag;
where Tag is a model in laravel project, that would result into:
Fatal error: Class 'Tag' not found in D:\xampp\htdocs\widgetsRepository\app\controllers\Run-PHP-Code-master\index.php(49) : eval()'d code on line 3
Any idea? this would be very useful!
EDIT
I tried Brian suggestion at his answer, but I got this error now:
Call to a member function connection() on null
at vendor\laravel\framework\src\Illuminate\Database\Eloquent\Model.php
public static function resolveConnection($connection = null)
{
return static::$resolver->connection($connection);
}
so, I think I only need to get database sorted, then I can do experiments easily..
I've never tried to run code from a laravel project directly, I just copy and paste parts of the code into Run PHP Code.
That being said, it should be possible to run the code using the method taken from this StackOverflow question:
The Composer autoload script, to autoload all of your classes:
require __DIR__.'/../bootstrap/autoload.php';
And if you need things from the IoC container, you'll:
$app = require_once __DIR__.'/../bootstrap/start.php';
Then you will be able to do things like:
$post = Post::find(1);

Getting CakeS3 to work in the CakeShell

I want to be able to call the CakeS3 plugin from the Cake Shell. However, as I understand it components cannot be loaded from the shell. I have read this post outlining strategies for overcoming it: using components in Cakephp 2+ Shell - however, I have had no success. The CakeS3 code here is similar to perfectly functioning cake S3 code in the rest of my app.
<?php
App::uses('Folder','Utility');
App::uses('File','Utility');
App::uses('CakeS3.CakeS3','Controller/Component');
class S3Shell extends AppShell {
public $uses = array('Upload', 'User', 'Comment');
public function main() {
$this->CakeS3 = new CakeS3.CakeS3(
array(
's3Key' => 'key',
's3Secret' => 'key',
'bucket' => 'bucket')
);
$this->out('Hello world.');
$this->CakeS3->permission('private');
$response = $this->CakeS3->putObject(WWW_ROOT . '/file.type' , 'file.type', $this->CakeS3->permission('private'));
if ($response == false){
echo "it failed";
} else {
echo "it worked";
}
}
This returns an error of "Fatal error: Class 'CakeS3' not found in /home/app/Console/Command/S3Shell.php. The main reason I am trying to get this to work is so I can automate some uploads with a cron. Of course, if there is a better way, I am all ears.
Forgive me this "advertising"... ;) but my plugin is probably better written and has a better architecture than this CakeS3 plugin if it is using a component which should be a model or behaviour task. Also it was made for exactly the use case you have. Plus it supports a few more storage systems than only S3.
You could do that for example in your shell:
StorageManager::adapter('S3')->write($key, StorageManager::adapter('Local')->read($key));
A file should be handled as an entity on its own that is associated to whatever it needs to be associated to. Every uploaded file (if you use or extend the models that come with the plugin, if not you have to take care of that) is stored as a single database entry that contains the name of the config that was used and some meta data for that file. If you do the line of code above in your shell you will have to keep record in the table if you want to access it this way later. Just check the examples in the readme.md out. You don't have to use the database table as a reference to your files but I really recommend the system the plugin implements.
Also, you might not be aware that WWW_ROOT is public accessible, so in the case you store sensitive data there it can be accessed publicly.
And finally in a shell you should not use echo but $this->out() for proper shell output.
I think the App:uses should look like:
App::uses('CakeS3', 'CakeS3.Controller/Component');
I'm the author of CakeS3, and no I'm afraid there is no "supported" way to do this as when we built this plugin, we didn't need to run uploads from shell and just needed a simple interface to S3 from our controllers. We then open sourced the plugin as a simple S3 connector.
If you'd like to have a go at modifying it to support shell access, I'd welcome a PR.
I don't have a particular road map for the plugin, so I've tagged your issue on github as an enhancement and will certainly consider it in future development, but I can't guarantee that it would fit your time requirements so that's why I mention you doing a PR.
