OR Import DB File
After Downloading the source code extract it in your root folder where found db folder to access db file.
- Open Phpmyadmin in your Browser
- Click on Database Tab Display on Top side
- Give the Database name “users”.
- After Creating Database Open it.
- Click on Import Tab on Top area
- You can Find Db file in Downloaded source code Select it.
- Then Click on Go.
2- Creating Database Connection
After import Database File then next step is creating database connection using php copy the below code and save it is as “config.php”.
<?php
define('DB_HOST', 'localhost');
define('DB_USER', 'root');
define('DB_PASS', '');
define('DB_NAME', 'users');
3 – Creating Index Page To Manage All Data
This step we are creating a page to manage all users easily named index.php. Source code are given below.
<?php
include_once('./config/Config.php');
include_once('./lib/Database.php');
include_once('./inc/header.php');
?>
<?php
$db = new Database();
$query = "SELECT * FROM tasks";
$read = $db->Select($query);
?>
<div class="container">
<h3 class="well text-center">How To Create User Manager in PHP MySQL</h3>
<table class="table">
<thead class="thead">
<tr>
<th>No</th>
<th>Firstname</th>
<th>Lastname</th>
<th>Telephone</th>
<th>Action</th>
</tr>
</thead>
<tbody>
<?php $i = 1; ?>
<?php if($read) { ?>
<?php while($row = $read->fetch_assoc()) { ?>
<tr>
<td><?php echo $i++; ?></td>
<td><?php echo $row['firstname']; ?></td>
<td><?php echo $row['lastname'];?></td>
<td><?php echo $row['phone']; ?></td>
<td><a href="update.php?id=<?php echo $row['id']; ?>" class="glyphicon glyphicon-edit btn btn-primary"> Edit</a></td>
<td><a href="delete.php?id=<?php echo $row['id']; ?>" class="glyphicon glyphicon-remove btn btn-danger"> Delete</a></td>
</tr>
<?php } ?>
<?php }else{ echo "DATA NOT FOUND"; } ?>
</tbody>
<span><a href="create.php" class="btn btn-success">Add Users</a></span>
</table>
</div>
4 – Create Form and Send Data into MySQL Database using PHP
This step we are creating a page named create.php here we are create a form in simple html and insert data into mysql database using php.
<?php
include_once('./config/Config.php');
include_once('./lib/Database.php');
include_once('./inc/header.php');
?>
<div class="container">
<h3 class="well text-center">How To Create User Manager in PHP MySQL</h3>
<?php
$db = new Database();
// check the form
if(isset($_POST['submit']))
{
$firstname= mysqli_real_escape_string($db->link, $_POST['firstname']);
$lastname = mysqli_real_escape_string($db->link, $_POST['lastname']);
$phone = mysqli_real_escape_string($db->link, $_POST['phone']);
if($firstname == '' || $lastname == '' || $phone == ''){
$errors = "<div class='alert alert-danger'> the fields can not be empty"."</div>";
echo $errors;
}else{
// insert into the database table
$sql = "INSERT INTO tasks(firstname, lastname, phone) VALUES('$firstname', '$lastname', '$phone')";
$createAll = $db->Insert($sql);
}
}
?>
<hr>
<span><a href="index.php" class="btn btn-success">Go Back</a></span>
<div style="max-width:500px; margin: 0 auto;">
<form action="create.php" method="post">
<div class="form-group">
<label for="Firstname">Firstname</label>
<input type="text" name="firstname" value="" class="form-control">
</div>
<div class="form-group">
<label for="Firstname">Lastname</label>
<input type="text" name="lastname" class="form-control">
</div>
<div class="form-group">
<label for="Firstname">Telephone</label>
<input type="number" name="phone" placeholder="numbers only" class="form-control">
</div>
<div class="form-group">
<input type="submit" name="submit" class="btn btn-primary" value="Add">
<input type="reset" name="reset" class="btn btn-success" value="Cancel">
</div>
</form>
</div>
</div>
5 – Creating Update Form and Validate using PHP
This step we are update inserted data into mysql using php.
<?php
include_once('./config/Config.php');
include_once('./lib/Database.php');
include_once('./inc/header.php');
?>
<div class="container">
<h3 class="well text-center">How To Create User Manager in PHP MySQL</h3>
<?php
$db = new Database();
$id = $_GET['id'];
$getid = "SELECT * FROM tasks WHERE id=$id";
$query_id = $db->Select($getid)->fetch_assoc();
// check the form
if(isset($_POST['submit']))
{
$firstname= mysqli_real_escape_string($db->link, $_POST['firstname']);
$lastname = mysqli_real_escape_string($db->link, $_POST['lastname']);
$phone = mysqli_real_escape_string($db->link, $_POST['phone']);
if($firstname == '' || $lastname == '' || $phone == ''){
$errors = "<div class='alert alert-danger'> the fields can not be empty"."</div>";
echo $errors;
}else{
// update the database table
$sql = "UPDATE tasks SET firstname ='$firstname', lastname='$lastname', phone='$phone' WHERE id=$id";
$update_id = $db->Update($sql);
}
}
?>
<hr>
<span><a href="index.php" class="btn btn-success">Go Back</a></span>
<div style="max-width:500px; margin: 0 auto;">
<form action="" method="post">
<div class="form-group">
<label for="Firstname">Firstname</label>
<input type="text" name="firstname" value="<?php echo $query_id['firstname']; ?>" class="form-control">
</div>
<div class="form-group">
<label for="Firstname">Lastname</label>
<input type="text" name="lastname" value="<?php echo $query_id['lastname']; ?>" class="form-control">

<!-- <input type="reset" name="reset" class="btn btn-success" value="Cancel"> -->
</div>
</form>
</div>
</div>
6 – Create Delete Function using PHP
This Function use for delete data from mysql database using php.
<?php
include_once('./config/Config.php');
include_once('./lib/Database.php');
include_once('./inc/header.php');
?>
<?php
$db = new Database();
$id = $_GET['id'];
$delete = "DELETE FROM tasks WHERE id=$id";
$deleteID = $db->Delete($delete);
?>
<h4 class="text-muted center"><a href="index.php"> GO back...</h4></p>
7 – Creating Error Function using PHP
This step we showing alert after fetching any types of error.
<?php
class Database {
public $host = DB_HOST;
public $user = DB_USER;
public $pass = DB_PASS;
public $dbname = DB_NAME;
public $link;
public $error;
public function __construct(){
$this->connectDB();
}
private function connectDB(){
$this->link = new mysqli($this->host, $this->user, $this->pass, $this->dbname);
if(!$this->link){
$this->error= "connection failed". $this->link->connect_error;
}
}
// read or select data
public function Select($query){
$result = $this->link->query($query) or die($this->link->error. __LINE__);
if($result->num_rows > 0){
return $result;
}else{
return false;
}
}
public function Insert($query){
$insert_row = $this->link->query($query) or die($this->link->error. __LINE__);
if($insert_row){
$success = "<h4 class = 'alert alert-success'>Inserted successfully!"."</h4>";
echo $success;
}else{
$this->link->error;
}
}
public function Update($query){
$update_id = $this->link->query($query) or die($this->link->error.__LINE__);
if($update_id){
$success = "<h4 class = 'alert alert-success'>Data Inserted successfully!"."</h4>";
echo $success;
}else{
$this->link->error;
}
}
public function Delete($query){
$delete_id = $this->link->query($query) or die($this->link->error.__LINE__);
if($delete_id){
$success = "<h4 class = 'alert alert-success'>Deleted successfully!"."</h4>";
echo $success;
}
