I want to have a little string converter (translator) helper method. For example, I want to pass my string from the controller and get the result, so I don't want to repeatedly write the same helper function into the controller.
So that I can maybe use it like:
$oldStr = '12 Mayıs 2014'; // which means 12 May in English
$englishStr = custom_date_translator($oldStr);
and it does it's thing on the helper method.
Is the Service Providers for this purpose? It'd be good to learn the right way to do it.
You can create a custom helpers.php file and setup Composer so that it's autoloaded.
For example, if you create the helpers.php file in the app/ directory, you could edit your composer.json file to something like this :
"autoload": {
"classmap": [
"database"
],
"psr-4": {
"App\\": "app/"
},
"files": [
"app/helpers.php"
]
},
Make sure to run composer dump-autoload in your console to update the autoloader.

I can see my alias present in app aliases array:
dd(app()); // ... "Me\Package\Facades\PHPFile" => "PHPFile"
using that same full name works
dd(
\Me\Package\Facades\PHPFile::load('app/User.php')
);
BUT trying to use the registered alias:
dd(
\PHPFile::load('app/User.php')
);
// Error: Class 'PHPFile' not found
Even though it was registered in app()! Any ideas whats going on here?
In my package composer.json:
"extra": {
"laravel": {
"dont-discover": [],
"providers": [
"Me\\Package\\MyServiceProvider"
],
"aliases": {
"PHPFile": "Me\\Package\\Facades\\PHPFile"
}
}
},
Also tried adding this in my serviceproviders register method:
$this->app->alias('PHPFile','Me\Package\Facades\PHPFile');
Host application composer.json
add
"repositories": [
{
"type": "path",
"url": "/full/path/to/packages/Me/Package"
}
],
Then install with composer require "me/package #dev"

I have a few tests which read data out of config.json file for determining the test details of each platform.
They look like this
{
"Devices" : {
"Settings": [
{
"Platform": "iOS",
"SerialNumbers": [
"b509b42b821a0b2eeb58ed5659e504c118d0323c"
],
"AssemblyPath": "realbundlename"
},
{
"Platform": "Android",
"SerialNumbers": [
"ZX1G22VMH7"
],
"AssemblyPath": "../../../Droid/bin/Release/nameoffile.apk"
}
]
}
}
The question is how to read data from json in UI Test App project.
I try to use Autofac and read data with module functionality, but when I debug I got that data not read from the file. I guess the problem with the type of project.
I try to develop it as in this article.
Does anyone know what the best way to do this is?
Or maybe someone has better idea how to read data from .json?
Use System.IO to read it from disk, and then use Json.Net to deserialize it.

I must hash database values before add to db and rehash after select for human friendly readable. Now I create "Helper\Helpers.php" in app folder. In the helpers file I have functions for encrypt/decrypt values. Helper file registered to composer autoloads:
"autoload": {
"classmap": [
"database/seeds",
"database/factories"
],
"psr-4": {
"App\\": "app/"
},
"files":[
"app/Helpers/Helpers.php"
]
},
In my opinion this method (file registration in the composer) is an unprotected option for registering a file of a function stored in itself for encryption. For more reliable protection where can I store and use files with encryption and decryption functions?
If you have a model defined, I would suggest Accessors and Mutators. It would allow you to encrypt the value before written to storage and then decrypt when read out:
// mutator
public function setMyHashedValueAttribute($value)
{
$this->attributes['my_hashed_value'] = encrypt($value);
}
// accessor
public function getMyHashedValueAttribute($value)
{
return decrypt($value);
}
I have a file called \App\Helpers, which contains a couple of functions one it to check if the user is an admin
#if(\Helper::isAdmin())
do something
#endif
I could add a method to the user model and get
$user->isAdmin()
This is a bit neater. However, is there any way just to do
#if(isAdmin())
do something
#endif
Yes, you can do this by creating a file with some global functions in it, so for example, add an entry in your composer.json file like one given below:
"autoload": {
"classmap": [
"database"
],
"psr-4": {
"App\\": "app/"
},
"files": [
"helpers/functions.php"
]
},
Notice the files section. then create a top level directory inside your project root as helpers and create the functions.php file inside it and declare your global functions, for example:
// helpers/functions.php
if (! function_exists('isAdmin')) {
function isAdmin()
{
// You can entirely rewrite the logic here or
// you can use your existing Helper::isAdmin()
return \Helper::isAdmin();
}
}
Don't forget to run composer dump-autoload at last. Btw, if you are in Larave 5.5.x then you may use larave'ls new Blade::if() Directives described here.
So I have a public directory in my localhost that contains some classes that I want to be able to use in my current laravel project.
So how will I include these, external classes/files in laravel?
I tried to add these files in my composer.json file,
"autoload": {
"classmap": [
"database",
"../public_classes/priceClass.php"
],
"psr-4": {
"App\\": "app/"
},
"files": [
"../public_classes/priceClass.php"
]
},
and do composer dump-autoload, then when I tried to call the function, it won't work.
You don't need to add anything in composer.json if you're using PSR-4. For example, you can create PHP file in \app\MyClasses\MyClass.php and use this namespace in custom class: namespace App\MyClasses.
Laravel will autoload this class for you.
I also wanted to include a few classes in my Laravel Project for that I just copied the files in a new directory(app/Libraries) and assigned Package name to all the classes and followed PSR-4 Autoloading standard for all those class files and I have added following code in my composer.json.
...
"autoload": {
"classmap": [
"app/Libraries",
],
...
hope this will solve your problem...
Happy to help!!!
What I end up doing was I put the path to file in my composer.json, then do composer dump-autoload.
composer.json:
"autoload": {
"classmap": [
"database",
"../public_classes/priceClass.php"
],
"psr-4": {
"App\\": "app/"
},
"files": [
"../public_classes/priceClass.php"
]
},
then, the file I wanted to add, I edit it into simple functions instead of oop ones.
priceClass.php:
<?php
function getPrices(){
/*
*
*
*Statements here
*
*/
}
?>
And call it in my laravel controller simply by
$prices = getPrices();
I did this, because when I tried to have something like:
class Prices(){
public function getPrices(){
....
}
}
then call it in my laravel controller:
$priceClass = new Prices();
$prices = $priceClass->getPrices();
I ended up having an error, something like: Prices class not found.
