config.php
Database connection configuration file, here you have to modify username, password and database details. If you are using other database modify PDO() driver connection value.

 

<?php
session_start();
/* DATABASE CONFIGURATION */
define('DB_SERVER', 'localhost');
define('DB_USERNAME', 'username');
define('DB_PASSWORD', 'password');
define('DB_DATABASE', 'databasename');
define("BASE_URL", "http://localhost/PHPLoginHash/"); // Eg. http://yourwebsite.com

function getDB()
{
$dbhost=DB_SERVER;
$dbuser=DB_USERNAME;
$dbpass=DB_PASSWORD;
$dbname=DB_DATABASE;
try {
$dbConnection = new PDO("mysql:host=$dbhost;dbname=$dbname", $dbuser, $dbpass);
$dbConnection->exec("set names utf8");
$dbConnection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
return $dbConnection;
}
catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
}
}
?>


blogClass.php
This class contains two methods blogPublish and blogDetails.

 

<?php
class blogClass
{
/* Blog Publish */
public function blogPublish($title,$body)
{
try{
$db = getDB();
$created=time();
$stmt = $db->prepare("INSERT INTO blog(title,body,created) VALUES(:title,:body,:created)");
$stmt->bindParam("title", $title,PDO::PARAM_STR) ;
$stmt->bindParam("body", $body,PDO::PARAM_STR) ;
$stmt->bindParam("created", $created,PDO::PARAM_INT) ;
$stmt->execute();
$bid=$db->lastInsertId();
$db = null;
return $bid;
}
catch(PDOException $e) {
echo '{"error":{"text":'. $e->getMessage() .'}}';
}
}

/* Blog Details */
public function blogDetails($bid)
{
try{
$db = getDB();
$stmt = $db->prepare("SELECT * FROM blog WHERE bid=:bid");
$stmt->bindParam("bid", $bid,PDO::PARAM_INT) ;
$stmt->execute();
$blogData=$stmt->fetch(PDO::FETCH_OBJ);
$db = null;
return $blogData;
}
catch(PDOException $e) {
echo '{"error":{"text":'. $e->getMessage() .'}}';
}
}

}
?>

$title=$_POST['title'];
$body=$_POST['body'];
