Tutorial

Hello everybody, I am Nawab. A full stack web developer in opensource community. Currently I am working on a project. My project is teaching everybody about app development. I am not good in English Language. My mother language is Bengali. I am living in UK from five years. Please forgive me if I write any grammatical errors.

Today I will teach you a very important tutorial. Most of the steemit users don't know that steemit has a system which is called withdraw routes.

If someone want to power down his steem power to another steemit account, he/she should use this system. This is not visible to steemit.com . You can use the system by STEEMJS API & STEEMCONNECT.

In this tutorial you will learn how to show Withdraw Routes.

First create check.php file. Use any HTML & CSS template in your page to look better. I use basic bootstrap template.

First, Include the header and the navigation bar template file.

<?php

/* Include header file */

include ('include/header.php');

/* Include navigation bar file */

include ('include/nav.php');
?>

Now write down this code.

 <form action="" method="post" >
      <div class="form-group">
      <label class="sr-only" for="inlineFormInputGroupUsername2">Username</label> 
      <div class="input-group mb-2 mr-sm-2"> 
      <div class="input-group-prepend"> <div class="input-group-text">@</div> </div> 
      <input type="text" class="form-control" name="user" id="inlineFormInputGroupUsername2" placeholder="Username"> </div> </div>

<br>
<div class="form-group">
 <button align="center" name="submit" class="btn btn-primary mb-2">Submit</button> 
 </div>
 </form>

I use bootstrap form template. This from will post Username in "user" strings.

Now we need to keep this strings to a variable.

<?php 
if($_POST)
{
$username = $_POST["user"];
}

When a user write his username and press the submit button, the username will store in $username.

Withdraw Routes API is https://api.steemjs.com/get_withdraw_routes and it has two parameters. One is account and the other is withdrawRouteType.

Write down this code

$data = file_get_contents('https://api.steemjs.com/get_withdraw_routes?account='.$username.'&withdrawRouteType=true');

When You use any API, we get data in JSON. Then you need to decode the json.

$info = json_decode($data,true);

You get "name" and "to_account" values. Keep these values in variables by this code

$name = $info[0][name];
$to = $info[0][to_account];
?>

Now print the $to variable.

Here is the full codes of my tutorial

<?php

/* Include header file */

include ('include/header.php');

/* Include navigation bar file */

include ('include/nav.php');
?>
 <div class="container">
 <br>
 <br>
 <center>
 <div class="card"> <h5 class="card-header">Check Withdraw Route</h5> <div class="card-body">

      <label class="sr-only" for="inlineFormInputGroupUsername2">Username</label> 
      <div class="input-group mb-2 mr-sm-2"> 
      <div class="input-group-prepend"> <div class="input-group-text">@</div> </div> 
 <input type="text" class="form-control" name="user" id="inlineFormInputGroupUsername2" placeholder="Username"> </div> </div>

<div class="form-group">

<?php

$username = $_POST["user"];
$data = file_get_contents('https://api.steemjs.com/get_withdraw_routes?account='.$username.'&withdrawRouteType=true');
$info = json_decode($data,true);
$name = $info[0][name];
$to = $info[0][to_account];
$too = "";
?>
<?php
if($to == $too)
{ 
?>
<div class="alert alert-danger" role="alert"> <h4 class="alert-danger">No Withdraw Routes Found!</h4>
