Tutorial Content

Hello Steemians,

I am Nawab. Last week an accident happened to me. So I didn't write any tutorial one week. Now I want to continue my steemtools php tutorial series. In this ongoing series, I have taught you to make some useful tools based on steemit in php language.

Here is the previous series -

Now I will teach you creating steemit account recovery tools. This tool has five part.

  1. Check current recovery Account
  2. Change recovery Account
  3. Check recovery Request
  4. Request account Recovery
  5. Recover Account

Today, I will teach you the first part today.

I am sorry to say that I am not good in the English language. My native language is Bengali. I am trying to improve the English language. Though I am a programmer and software engineer, I am not good in the English language. And it is my weak point. Please forgive me if my tutorial has some grammatical errors

What is steem account recovery?

Every steem account has a recovery account. If any user forgets his password/ owner key, he/she can recover his account by recovery account.
For example, Every google account has an alternative email/phone number. If a user forget his password, he can recover his password by his alternative email/ phone number.
Steem account recovery is the same as google account recovery. By default, every steem account's recovery account is steem. You can change your recovery account so that you can recover your steem account anytime by using an alternative account.

Check current recovery account

Now I will teach you how to create a tool which will show recovery account of any steem account.
Its function is the same as " Check current withdraw Route " tool's function. I have already described it in part -2 of this series. So I will not explain all the codes. Because You already know about these functions.

First, create a file named checkrecovery.php in the main directory of your PHP website. Then open the file and follow the steps one by one.

Include Header : First include header and sidebar files. Write down this code;

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

Username Input Form : Create a simple form like bootstrap form. You can use any kind of bootstrap form.

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

</form>

Add an input box and a submit box into the form. Write this code inside the <form>...</form> tag.

<div class="form-group">
  <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="Username">
   </div>
</div>

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

Php Function : Finally write some php functions for run this tools.

  • Store username from Html Form.
<?php 
if($_POST)
{
$username = $_POST["user"];
  • Generate API address of SteemJS.
$url = "https://api.steemjs.com/get_accounts?names[]=$username";
  • Use CURL function to get account information in JSON from SteemJS.
//  Initiate curl
$ch = curl_init();
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch, CURLOPT_URL,$url);
// Execute
$result=curl_exec($ch);
// Closing
curl_close($ch);
  • Decode JSON to PHP strings
$info = json_decode($result,true);
  • Store php strings to variables.
$name = $info[0][name];
$to = $info[0][recovery_account];
?>
  • Display the Result
<div class="alert alert-success" role="alert"> <h4 class="alert-heading">Hi <?php echo $name; ?> </h4> <p>Your current recovery account is <b>@<?php
echo $to; ?> </b>
</p> <hr> <p class="mb-0">You can change your Recovery account from <a href="changerecovery">here</a> </p> </div>
<?php
}
?>

Then save the file.

Here is the full code .

<?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 Current Recovery Account</h5> <div class="card-body"> 
      <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">@</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>
</div> </div>
</center>
      
<?php 
if($_POST)
{
$username = $_POST["user"];
$url = "https://api.steemjs.com/get_accounts?names[]=$username";  //steemjs API
//  Initiate curl
$ch = curl_init();
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch, CURLOPT_URL,$url);
// Execute
$result=curl_exec($ch);
// Closing
curl_close($ch);
$info = json_decode($result,true);  //decode json
$name = $info[0][name];  //store username value
$to = $info[0][recovery_account];  //store recovery account value
?>
<div class="alert alert-success" role="alert"> <h4 class="alert-heading">Hi <?php echo $name; ?> </h4> <p>Your current recovery account is <b>@<?php
echo $to; ?> </b>
</p> <hr> <p class="mb-0">You can change your Recovery account from <a href="changerecovery">here</a> </p> </div>
<?php

}
?>
<br>
<br>
<p>
<hr>
</div>
<?php
include ('include/footer.php');
?>
