How to Select Data By Month and Year in PHP/MySQL

In my previous tutorial, I've discussed How to Select Data between two Dates. So, I've created another topic regarding selecting data with dates which is on How to Select Data by Month and Year using PHP. Also, in this tutorial, I've created two mysqli methods that I've added in the comment so feel free to switch between them.

Creating our Database

First, we're going to create a database that contains our data. 1. Open phpMyAdmin. 2. Click databases, create a database and name it as "month_year". 3. After creating a database, click the SQL and paste the below code. See image below for detailed instruction.

CREATE TABLE `login` (
  `logid` INT(11) NOT NULL AUTO_INCREMENT,
  `username` VARCHAR(30) NOT NULL,
  `login_date` datetime NOT NULL,
  PRIMARY KEY(`logid`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

Inserting Data Into our Database

Next Step in to insert some data into our database. This will serve as our reference when we select our month and year. 1. Click the database "month_year" that we have created earlier. 2. Click SQL and paste the code below.

INSERT INTO `login` (`username`, `login_date`) VALUES
('nurhodelta', '2017-08-22 07:10:00'),
('lee', '2017-05-22 08:30:00'),
('nurhodelta', '2017-08-22 13:15:00'),
('lee', '2017-03-22 14:00:00'),
('nurhodelta', '2017-05-16 10:30:00'),
('lee', '2017-08-15 20:00:00');

Creating our Connection

Next step is to create a database connection and save it as "conn.php". This file will serve as our bridge between our form and our database. To create the file, open your HTML code editor and paste the code below after the tag.

<?php
 
//MySQLi Procedural
$conn = mysqli_connect("localhost","root","","month_year");
if (!$conn) {
  die("Connection failed: " . mysqli_connect_error());
}
 
//MySQLi Object-oriented
//$conn = new mysqli("localhost","root","","month_year");
//if ($conn->connect_error) {
//    die("Connection failed: " . $conn->connect_error);
//} 
 
?>

Creating our Form and Table

Lastly, we create our login table, our form and our result table on one page. To create the page, open your HTML code editor and paste the code below after the tag. We name this page as "index.php".

<!DOCTYPE html>
<html>
<head>
<title>Select Data By Month and Year</title>
</head>
<body>
<h2>Login Table</h2>
<div>
	<table border="1">
		<thead>
			<th>UserID</th>
			<th>Username</th>
			<th>Login Date</th>
		</thead>
		<tbody>
		<?php
			include('conn.php');
			//MySQLi Procedural
			$query=mysqli_query($conn,"select * from `login`");
			while($row=mysqli_fetch_array($query)){
				?>
				<tr>
					<td><?php echo $row['logid']; ?></td>
					<td><?php echo $row['username']; ?></td>
					<td><?php echo $row['login_date']; ?></td>
				</tr>
				<?php 
			}
 
			//MySQLi Object-oriented
			//$query=$conn->query("select * from `login`");
			//while($row = $query->fetch_array()) {
			/*	?>
				<tr>
					<td><?php echo $row['logid']; ?></td>
					<td><?php echo $row['username']; ?></td>
					<td><?php echo $row['login_date']; ?></td>
				</tr>
				<?php */
			//}
		?>
		</tbody>
	</table>
</div><br>
<div>
	<form method="POST">
		<label>Month: </label>
			<select name="month">
			<?php
 
				for ($i = 1; $i <= 12; $i++)
				{
					$month = date('F', mktime(0, 0, 0, $i, 1, 2011));
					?>
					<option value="<?php echo $i; ?>"><?php echo $month; ?></option>
					<?php
				}
 
            ?>
			</select>
 
		<label>Year: </label>
			<select name="year">
			<?php
				for($n=2017;$n<=2050;$n++){
					?>
					<option value="<?php echo $n; ?>"><?php echo $n; ?></option>
					<?php
				}
			?>
			</select>
		<input type="submit" value="Get Data" name="submit">
	</form>
</div>
<h2>Data in Selected Month and Year</h2>
<div>
	<table border="1">
		<thead>
			<th>UserID</th>
			<th>Username</th>
			<th>Login Date</th>
		</thead>
		<tbody>
		<?php
			if (isset($_POST['submit'])){
				include('conn.php');
				$month=$_POST['month'];
				$year=$_POST['year'];
 
				//MySQLi Procedural
				$oquery=mysqli_query($conn,"select * from `login` where month(login_date)='$month' and year(login_date)='$year'");
				if (mysqli_num_rows($oquery) <=0){
					echo "No data Found.";
				}
				else{
				while($orow=mysqli_fetch_array($oquery)){
					?>
					<tr>
						<td><?php echo $orow['logid']?></td>
						<td><?php echo $orow['username']?></td>
						<td><?php echo $orow['login_date']?></td>
					</tr>
					<?php 
				}
				}
 
				//MySQLi Object-oriented
				//$oquery=$conn->query("select * from `login` where month(login_date)='$month' and year(login_date)='$year'");
				//if ($oquery->num_rows <= 0) {
				//	echo "No data Found.";
				//}
				//else{
				//while($orow = $oquery->fetch_array()){
				/*	?>
					<tr>
						<td><?php echo $orow['logid']?></td>
						<td><?php echo $orow['username']?></td>
						<td><?php echo $orow['login_date']?></td>
					</tr>
					<?php  */
				//}
				//}
			}
		?>
		</tbody>
	</table>
