You can watch the video here to see the running application of User Profile With Update Profile Info Using PHP/MYSQL.

Steps to Create User Profile With Update Profile Info Using PHP/MYSQL

Step 1. First, create a database, name it as any name you desire. In my case, I use “ITSOURCECODE” as the name of the database. Step 2. Then create the”USERS” table then put the following attributes.

CREATE TABLE `users` (  `user_id` int(11) NOT NULL,
  `username` text NOT NULL, 
`password` text NOT NULL,
  `full_name` text NOT NULL, 
`gender` text NOT NULL, 
`age` int(11) NOT NULL, 
`address` text NOT NULL)
ENGINE=MyISAM DEFAULT CHARSET=latin1;

Make sure you are done doing in the login and registration. A link will be seen and view on the link above. And Make sure to Create a “connection.php” file to hold the database connection to our PHP project.

<?php
$db = mysqli_connect('localhost', 'root', '') or
        die ('Unable to connect. Check your connection parameters.');
        mysqli_select_db($db, 'mydb' ) or die(mysqli_error($db));
?>

Step 3. For the user’s profile, create and update “profile.php” file then put the following codes.

<!DOCTYPE html>
<html lang="en-US">
  <head>
  <title>IT SourceCode</title>
  <link rel="stylesheet" href="libs/css/bootstrap.min.css">
  <link rel="stylesheet" href="libs/style.css">
  </head>
  <?php
  include 'connection.php';
  session_start();
$id=$_SESSION['id'];
$query=mysqli_query($db,"SELECT * FROM users where user_id='$id'")or die(mysqli_error());
$row=mysqli_fetch_array($query);
  ?>
  <h1>User Profile</h1>
<div class="profile-input-field">
        <h3>Please Fill-out All Fields</h3>
        <form method="post" action="#" >
          <div class="form-group">
            <label>Fullname</label>
            <input type="text" class="form-control" name="fname" style="width:20em;" placeholder="Enter your Fullname" value="<?php echo $row['full_name']; ?>" required />
          </div>
          <div class="form-group">
            <label>Gender</label>
            <input type="text" class="form-control" name="gender" style="width:20em;" placeholder="Enter your Gender" required value="<?php echo $row['gender']; ?>" />
          </div>
          <div class="form-group">
            <label>Age</label>
            <input type="number" class="form-control" name="age" style="width:20em;" placeholder="Enter your Age" value="<?php echo $row['age']; ?>">
          </div>
          <div class="form-group">
            <label>Address</label>
            <input type="text" class="form-control" name="address" style="width:20em;" required placeholder="Enter your Address" value="<?php echo $row['address']; ?>"></textarea>
          </div>
          <div class="form-group">
            <input type="submit" name="submit" class="btn btn-primary" style="width:20em; margin:0;"><br><br>
            <center>
             <a href="logout.php">Log out</a>
           </center>
          </div>
        </form>
      </div>
      </html>
      <?php
      if(isset($_POST['submit'])){
        $fullname = $_POST['fname'];
        $gender = $_POST['gender'];
        $age = $_POST['age'];
        $address = $_POST['address'];
      $query = "UPDATE users SET full_name = '$fullname',
                      gender = '$gender', age = $age, address = '$address'
                      WHERE user_id = '$id'";
                    $result = mysqli_query($db, $query) or die(mysqli_error($db));
                    ?>
                     <script type="text/javascript">
            alert("Update Successfull.");
            window.location = "index.php";
        </script>
        <?php
             }              
?>

Step 4. Update the “index.php” file by putting the following codes.

<!DOCTYPE html>
<html lang="en-US">
  <head>
  <title>IT SourceCode</title>
  <link rel="stylesheet" href="libs/css/bootstrap.min.css">
  <link rel="stylesheet" href="libs/style.css">
  </head>
  <h1>User Log In</h1>
<div class="input-field">
        <h3>Please Fill-out All Fields</h3>
        <form method="post" action="#" >
          <div class="form-group">
            <label>Username</label>
            <input type="text" class="form-control" name="user" style="width:20em;" placeholder="Enter your Username" required />
          </div>
          <div class="form-group">
            <label>Password</label>
            <input type="password" class="form-control" name="pass" style="width:20em;" placeholder="Enter your Password" required />
          </div>
          <div class="form-group">
            <input type="submit" name="submit" class="btn btn-primary submitBtn" style="width:20em; margin:0;" /><br><br>
            <center>
             <a href="register.php">register</a>
           </center>
          </div>
          
        </form>
      </div>
      </html>
      <?php
      session_start();
      include 'connection.php';
if(isset($_POST['submit'])){
  $user = $_POST['user'];
  $pass = $_POST['pass'];
  $query=mysqli_query($db,"SELECT * FROM users WHERE username = '$user' AND password = '$pass'");
  $num_rows=mysqli_num_rows($query);
  $row=mysqli_fetch_array($query);
  $_SESSION["id"]=$row['user_id'];
if ($num_rows>0)
{
    ?>
    <script>
      alert('Successfully Log In');
      document.location='profile.php'
    </script>
    <?php
}
}
      ?>

Step 5. For registration of user profile information, create “register.php” file then put the following codes.

<!DOCTYPE html>
<html lang="en-US">
  <head>
  <title>IT SourceCode</title>
  <link rel="stylesheet" href="libs/css/bootstrap.min.css">
  <link rel="stylesheet" href="libs/style.css">
  </head>
  <h1>Register</h1>
<div class="reg-input-field">
        <h3>Please Fill-out All Fields</h3>
        <form method="post" action="#" >
          <div class="form-group">
            <label>Fullname</label>
            <input type="text" class="form-control" name="fname" style="width:20em;" placeholder="Enter your Fullname" required />
          </div>
          <div class="form-group">
            <label>Gender</label>
            <input type="text" class="form-control" name="gender" style="width:20em;" placeholder="Enter your Gender" required pattern="[a-zA-Z .]+" />
          </div>
          <div class="form-group">
            <label>Age</label>
            <input type="number" class="form-control" name="age" style="width:20em;" placeholder="Enter your Age">
          </div>
          <div class="form-group">
            <label>Address</label>
            <input type="text" class="form-control" name="address" style="width:20em;" required placeholder="Enter your Address"></textarea>
          </div>
          <div class="form-group">
            <label>Username</label>
            <input type="text" class="form-control" name="user" style="width:20em;" placeholder="Enter your Username">
          </div><div class="form-group">
            <label>Password</label>
            <input type="Password" class="form-control" name="pass" style="width:20em;" required  placeholder="Enter your Password">
          </div>
          <div class="form-group">
            <input type="submit" name="submit" class="btn btn-primary submitBtn" style="width:20em; margin:0;" /><br><br>
             <center>
             <a href="index.php">LogIn</a>
           </center>
          </div>
        </form>
      </div>
      </html>
      <?php
      include 'connection.php';
if(isset($_POST['submit'])){
$fname = $_POST['fname'];
$gender = $_POST['gender'];
$age = $_POST['age'];
$address = $_POST['address'];
$user = $_POST['user'];
$pass = $_POST['pass'];
 
 
  $query = "INSERT INTO users
                (username, password, full_name,gender,age,address)
                VALUES ('".$user."','".$pass."','".$fname."','".$gender."','".$age."','".$address."')";
                mysqli_query($db,$query)or die ('Error in updating Database');
                ?>
                <script type="text/javascript">
            alert("Successfull Added.");
            window.location = "index.php";
        </script>
                <?php
}
      ?>

Step 6. For the logout of user action, create “logout.php” file then put the following codes.

<?php
session_start();
unset($_SESSION['id']);
session_destroy();
header("Location: index.php");
?>
