BrainTree Payment API | Create Refund | Refund Payment

For merchant ID, public key and private key you can have a look at below link:

http://pritomkumar.blogspot.com/2017/07/braintree-create-payment-token-store.html

Below is full example given:

<?php
require_once "CurlExecutor.php";
require_once "BrainTreeUtils.php";

define("MERCHANT_ID", "k9y......xj6");
define("PUBLIC_KEY", "85....hh7");
define("PRIVATE_KEY", "510d5......................a00");

$array = array(
    "transaction" => array(
        'amount' => "1.00",
        'orderId' => htmlentities("REFUND_ID_" . time())
    )
);

$base = "/transactions/6wex6xr6/refund";
$test = "https://api.sandbox.braintreegateway.com:443/merchants/" . MERCHANT_ID . $base;
$live = "https://api.braintreegateway.com:443/merchants/" . MERCHANT_ID . $base;

$headers[] = "Accept: application/xml";
$headers[] = "Content-Type: application/xml";
$headers[] = "X-ApiVersion: 4";
$closure = function(&$curl) {
    curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($curl, CURLOPT_USERPWD, PUBLIC_KEY . ':' . PRIVATE_KEY);
};
$result = CurlExecutor::execute(
    $test, "POST", BrainTreeUtils::arrayToXml($array),
    null, $headers, $closure
);
CurlExecutor::prettyPrint(BrainTreeUtils::arrayFromXml($result["response"]));

Response from BrainTree Payment Gateway:

BrainTree API | Create Payment | Create Payment Using Credit Card | Credit Card Payment

For merchant ID, public key and private key you can have a look at below link:

http://pritomkumar.blogspot.com/2017/07/braintree-create-payment-token-store.html

Below is a full PHP script:

'submitForSettlement' => true|false

The option that determines whether an authorized transaction is submitted for settlement.

<?php
require_once('CurlExecutor.php');
require_once "BrainTreeUtils.php";

define("MERCHANT_ID", "k......8xj6");
define("PUBLIC_KEY", "85......brhh7");
define("PRIVATE_KEY", "510d.............8a00");

$array = array(
    "transaction" => array(
        "type" => "sale",
        'amount' => "1.00",
        'orderId' => htmlentities("ORDER_ID_" . time()),
        'creditCard' => array(
            'cardholderName' => htmlentities("Test"),
            'number' => htmlentities("4444333322221111"),
            'expirationMonth' => htmlentities("12"),
            'expirationYear' => htmlentities("18")
        ),        'options' => array(
            'submitForSettlement' => true
        )
)
);

$test = "https://api.sandbox.braintreegateway.com:443/merchants/" . MERCHANT_ID . "/transactions";
$live = "https://api.braintreegateway.com:443/merchants/" . MERCHANT_ID . "/transactions";

$headers[] = "Accept: application/xml";
$headers[] = "Content-Type: application/xml";
$headers[] = "X-ApiVersion: 4";
$closure = function(&$curl) {
    curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($curl, CURLOPT_USERPWD, PUBLIC_KEY . ':' . PRIVATE_KEY);
};
$result = CurlExecutor::execute(
    $test, "POST", BrainTreeUtils::arrayToXml($array),
    null, $headers, $closure
);
CurlExecutor::prettyPrint(BrainTreeUtils::arrayFromXml($result["response"]));

And output/response from BrainTree API is below:

BrainTree API | Create Payment | Create Payment Using Stored Token | Token Payment

For merchant ID, public key and private key you can have a look at below link:

http://pritomkumar.blogspot.com/2017/07/braintree-create-payment-token-store.html

Below is a full PHP script:

You can also specify "customerId" instead of "paymentMethodToken" in the below variable $array (filled red color) as:

"customerId" => "brain_tree_customer_id" and then default payment method of the selected customer will be used.

'submitForSettlement' => true|false

The option that determines whether an authorized transaction is submitted for settlement.

<?php
require_once('CurlExecutor.php');
require_once "BrainTreeUtils.php";

define("MERCHANT_ID", "k9yxxxxxxj6");
define("PUBLIC_KEY", "85xxxxxxrhh7");
define("PRIVATE_KEY", "510xxxxxxxxxxxxxxxxxxxx8a00");

$array = array(
    "transaction" => array(
        "type" => "sale",
        'amount' => "1.00",
        'paymentMethodToken' => "6m76wy",
        'orderId' => htmlentities("ORDER_ID_" . time()),        'options' => array(
            'submitForSettlement' => true
        )
)
);

$test = "https://api.sandbox.braintreegateway.com:443/merchants/" . MERCHANT_ID . "/transactions";
$live = "https://api.braintreegateway.com:443/merchants/" . MERCHANT_ID . "/transactions";

$headers[] = "Accept: application/xml";
$headers[] = "Content-Type: application/xml";
$headers[] = "X-ApiVersion: 4";
$closure = function(&$curl) {
    curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($curl, CURLOPT_USERPWD, PUBLIC_KEY . ':' . PRIVATE_KEY);
};
$result = CurlExecutor::execute(
    $test, "POST", BrainTreeUtils::arrayToXml($array),
    null, $headers, $closure

BrainTree: Create Payment Token | Store Credit Card Details | Create Customer | Create Credit Card Token | Create Payment Method

The very step to create an account in BrainTree. And then need to create an user and then application.

1. Visit https://sandbox.braintreegateway.com
2. Click on "Settings" -> "Users and roles" and then click "New User" to create a new user.

3. Now click "Account" -> "My User" and then "View Authorizations".

4. Now click on "Generate New API Key" to create an API key. Copy "Public Key" and "Private Key".

5. What we need to communicate with BrainTree API in our hand now. Now its time to communicate with BrainTree API.

Below is a screenshot to show how you can collect your Merchant ID:

And below PHP script is full example how to create token in BrainTree portal:

<?php
require_once('CurlExecutor.php');
require_once "BrainTreeUtils.php";

define("MERCHANT_ID", "kxxxxnxxxxxxxx");
define("PUBLIC_KEY", "85dspxxxxxxxxxx");
define("PRIVATE_KEY", "510d5b5b672xxxxxxxxxxxxxxxxxxx");

$array = array(
    "customer" => array(
        'firstName' => htmlentities("Pritom"),
        'lastName' => htmlentities("Kumar"),
        'company' => htmlentities("My Company"),
        'email' => htmlentities("pritomkucse@gmail.com"),
        'phone' => htmlentities("33303030"),

        'creditCard' => array(
            'cardholderName' => htmlentities("Test"),
            'number' => htmlentities("4444333322221111"),
            'expirationMonth' => htmlentities("12"),
            'expirationYear' => htmlentities("18"),
            'cvv' => htmlentities("354"),
            'billingAddress' => array(
                'firstName' => htmlentities("Pritom"),
                'lastName' => htmlentities("Kumar")
            )
        )
    )
);

$test = "https://api.sandbox.braintreegateway.com:443/merchants/" . MERCHANT_ID . "/customers";
$live = "https://api.braintreegateway.com:443/merchants/" . MERCHANT_ID . "/customers";
$headers[] = "Accept: application/xml";
$headers[] = "Content-Type: application/xml";
$headers[] = "X-ApiVersion: 4";
$closure = function(&$curl) {
    curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($curl, CURLOPT_USERPWD, PUBLIC_KEY . ':' . PRIVATE_KEY);
};
$result = CurlExecutor::execute(
    $test, "POST", BrainTreeUtils::arrayToXml($array),
    null, $headers, $closure
);
CurlExecutor::prettyPrint(BrainTreeUtils::arrayFromXml($result["response"]));

And successful output of above script is below. From the response below you have to store customer id and token for further use of customer to update, add new payment method, create payment etc...

And below is screenshot to show that token created on BrainTree end:

Strip HTML Entities | Remove HTML Tags From String | Stripping HTML Tags in Java | Remove Html Tags From String Using Java | Java: RegEx To Remove HTML Tags

I am writing one program which reads text contents from file. Now I am reading it using bufferedreader class of java. I am able to remove any unwanted characters like '(' or '.' etc, using replaceAll() method. But I want to remove html tags too like "div", "span", "p" and many others like this, including &amp. How to achieve this? Is there a good way to remove HTML from a Java string? Yes, we can using regex. Below is full example written in Java to strip html entities from text.

Laravel 5: Get Controller Name in View | Route Details | Controller & Action Name | Route Parameters

You can create a view composer that injects those variables into your view file. In "app/Providers/AppServiceProvider.php" add something like this:

public function boot()
{
//app('view')->composer("folder.specific_view_name", function ($view) {
app('view')->composer("*", function ($view) {
$action = app("request")->route()->getAction();

$controller = class_basename($action["controller"]);

list($controller_name, $action_name) = explode("@", $controller);

$view->with(compact("controller_name", "action_name"));
});
}

You also can parameters from current request as below:

app('request')->route()->parameters()

Array
(
[middleware] => web
[as] => folder.view_name
[uses] => App\Http\Controllers\UserController@show
[controller] => App\Http\Controllers\UserController@show
[namespace] => App\Http\Controllers
[prefix] =>
[where] => Array
(
)

)

Laravel 5: Logging All DB Query | Log Queries | Listen Query Events | Query Logging | Sql Logging | Log SQL | DB Connection Class | Laravel Database Connection | Laravel DB Connection Query Run Method

Laravel 5: Logging All DB Query | Log Queries | Listen Query Events | Query Logging | Sql Logging | Log SQL | DB Connection Class | Laravel Database Connection | Laravel DB Connection Query Run Method.

Logging query in Laravel is easy. You can then register event listener for DB. At first you need to create an service provider in directory ("project/app/Providers" ) named QueryLogProvider with following contents:

<?php
namespace App\Providers;

use Monolog\Logger;
use Illuminate\Support\Facades\DB;
use Monolog\Handler\StreamHandler;
use Illuminate\Support\ServiceProvider;

class QueryLogProvider extends ServiceProvider
{
    public function register()
    {
        DB::listen(function ($query) {
            $logFile = storage_path('logs/query-log-'.date("Y-m-d").'.log');
            $stream = new Logger('log');
            $stream->pushHandler(new StreamHandler($logFile));
            $bindings = $query->bindings;
            $time = $query->time;
            $stream->info($query->sql, compact('bindings', 'time'));
        });
    }
}

You are done with creating provider. Now you have to register in file "project/config/app.php" in section

'providers' => [
    .....,
    App\Providers\QueryLogProvider::class
],

All your queries will be stored on the location "project/storage/logs" with prefix file name "query-log".

But you can do some wired things, editing source code. To do so first need to open your connection class:

Illuminate\Database\Connection

and navigate to function:

protected function run($query, $bindings, Closure $callback)

actually all query in Laravel passed through this method.

So you can do whatever you wish to do here.
