How to Get Yesterday and Tomorrow using MySQL SQL Query

Problem: You need to fetch previous days record from a table which has date column.

Solution: You will use Joomla Form API.

<?php

$servername = "localhost";
$username = "youruser";
$password = "yourpass";
$dbname = "DBname";

// Now make connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Then test connection
if ($conn->connect_error) {
  die("Connection failed: " . $conn->connect_error);
}

$sql ="SELECT * FROM <tablename> WHERE date(on_date) = curdate() - INTERVAL 1 DAY";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
  // Now output data of each row
  while($row = $result->fetch_assoc()) {
    echo "<div>".$row["id"]." : ".$row["firstname"]." ".$row["lastname"]."</div>";
  }
} else {
  echo "0 results";
}
$conn->close();


?>
