Description

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. I am living in UK from five years. Please forgive me if I write any grammatical errors.

In my previous tutorials you have learned how to check & Change withdraw route by php+steemjs+steemconnect.

Today I will teach you how to remove withdraw routes with PHP+STEEMJS+STEEMCONNECT

Before read this tutorial, please read my previous tutorials.

In my 1st & 2nd tutorial, I taught you creating check.php and change.php. I will use both these system to remove withdraw routes.

If you want to change or remove your withdraw route, you have to input 4 data. These are-

From Account
To Account
Percentage
Auto Vest

If you want to remove your withdraw routes you have to use these values,

parameters	values
from_account	your steemit account username
to_account	your exists withdraw route's steemit username
percent	0
auto	false

Here is the flow-chart of this tools;

Remove.php

confirmremove.php

How it works

Remove.php

First we input 'from_account' and submit it. Then it will connect to SteemJs API and get output of 'to_account'. Finally, it will send data to confirmremove.php page and redirect to that page.

ConfirmRemove.php

First it get value of 'form_account' and 'to_account'. Then the data will show in a form but remain readonly. and other input 'percent' & 'auto' will remain hidden. When user confirm the value & press 'remove' (submit button) , it will redirect to steemconnect.

Tutorial

First create remove.php file. Then insert header files.

<?php
include ('include/header.php'); // Include header
include ('include/nav.php'); // Include Navigation bar
?>

Create a form to input username. I use bootstrap form and at input tag name attribute value is user…

 <form action="" method="post" >
           <div class="form-group">
             <label class="sr-only">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" placeholder="Enter your username">
               </div> 
           </div>
               <br>
                 <div class="form-group">
                   <button align="center" name="submit" class="btn btn-primary mb-2">Next</button> 
                 </div>
           </form>

Then write php code to connect with SteemJs and get data form it. I have described it in Tutorial-2 of these series.

<?php 
if($_POST)
{
  $username = $_POST["user"];
  $data = file_get_contents('https://api.steemjs.com/get_withdraw_routes?account='.$username.'&withdrawRouteType=true');         // steemjs Api
  $info = json_decode($data,true);            // decode from json to php strings                   
  $to = $info[0][to_account];                 // keep 'to_account' string's value at variable
    header("Location: confirmremove.php?user=$username&to=$to");   // redirect to confirmremove.php 
}
?>

Explanation

Here I use If condition. If someone post username with these form, the code inside the 2nd bracket will run.

First inputed username from form will store in $username variable.
Then withdraw route json data will be taken by steemjs API and store at $data variable.
JSON will be decoded to strings at next line and stored at $info variable. $to variable only select to_account value.
Last line I have used header() php function to redirect it to confirmremove.php and give two parameters. One is user and the other is to. And gives their values $username & $to.

Example

For example, If I put my username nawab69 and press submit/next button. It will get my withdraw routes details by STEEMJS API.

Suppose, My withdraw route is utopian-io.
What will happen if I press submit/next button?

The page will redirect to /confirmremove.php?user=nawab69&to=utopian-io

Step-2

Now create another file confirm.php

Include the header file same as remove.php

<?php
include ('include/header.php'); // Include header
include ('include/nav.php'); // Include Navigation bar
?>

In step-1, user & to parameters' value has sent to this page. Now write this code to get this values and keep them at variables.

<?php
$usname = $_GET["user"];    // get data from user
$touser = $_GET["to"];      // get data from to
?>

Then create a form with these formula,

name	value	attribute
user	$usname	readonly
to	$to	readonly
percent	0	hidden
auto	false	hidden

Write down these code to create the form.

  <form action="" method="post" >

        <div class="form-group">
             <div class="input-group mb-2 mr-sm-2"> 
            <div class="input-group-prepend">
              <div class="input-group-text">From</div> 
            </div>         
      <input type="text" class="form-control" value="" name="user"  placeholder="Username" readonly> 
         </div>
        </div>

        <div class="form-group">
          <div class="input-group mb-2 mr-sm-2"> 
            <div class="input-group-prepend">
             <div class="input-group-text">To</div>
            </div> 
              <input type="text" class="form-control" name="to"  placeholder="Withdraw To" value="" readonly>
          </div>
       </div>

    <input type="text" class="form-control" name="percent" value="0" hidden>

    <input type="text" class="form-control" name="auto" value="false" hidden>
<br>

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

The red mark of this image is hidden attribute. It hide input box from user but still work.

Because of using readonly attribute at first two box, they aren't be editable any more. And because of using hidden attribute at last two input box, they will be hidden.

Now, write this php code to run this.

<?php
if($_POST)
{
$from = $_POST["user"];   // store username from Form using post method
$to = $_POST["to"];     // store withdraw to username from Form using post method
$percent = $_POST["percent"];  // store percentage from Form using post method
$auto = $_POST["auto"]; //   store auto vest boolian from Form using post method
$api = "https://steemconnect.com/sign/set_withdraw_vesting_route?from_account=$from&to_account=$to&percent=$percent&auto_vest=$auto";   // steemconnect Api for changing withdraw routes
header("Location: $api");   // redirect to steemconnect
}
?>
