select mysqli data by monthly using php

In this tutorial, we will create a Select MySQLi Data By Monthly using PHP. This code will select a specific MySQLi table row when the user submits a month and year from a form. The code use MySQLi SELECT query to select data in the MySQLi row, and by providing a month and year in the WHERE clause, it will display that particular database on the given month and year. This a user-friendly program; feel free to modify and use it to your system.

We will be using PHP as a scripting language and interpreter that is used primarily on any web server, including xamp, wamp, etc. It is being used to any popular websites because of the modern approach as its today.

Getting Started:

First, you have to download & install XAMPP or any local server that runs PHP scripts. Here’s the link for the XAMPP server https://www.apachefriends.org/index.html.

And, this is the link for the bootstrap that I used for the layout design https://getbootstrap.com/.

Creating Database

Open your database web server then create a database name in it db_month, after that, click Import, then locate the database file inside the folder of the application then click ok.

Creating the database connection

Open your any kind of text editor(notepad++, etc..). Then just copy/paste the code below then name it conn.php.

<?php
    $conn=mysqli_connect("localhost", "root", "", "db_month");
 
    if(!$conn){
        die("Error: Failed to connect to database!");
    }
?>

Creating The Interface

This is where we will create a simple form for our application. To create the forms simply copy and write it into your text editor, then save it as index.php.

                                $month = date('F', mktime(0, 0, 0, $i, 1, 2019));
                        ?>
                                <option value="<?php echo $i; ?>"><?php echo $month; ?></option>
                        <?php
                            }
                        ?>
                    </select>
                    <label>Year: </label>
                    <select name="year" class="form-control">
                        <?php
                            for ($i = date('Y'); $i >= 1965; $i--){
                        ?>
                            <option value="<?php echo $i; ?>"><?php echo $i; ?></option>
                        <?php
                            }
                        ?>
                    </select>
                    <button class="btn btn-primary" name="search">Search</button>
                </div>
            </form>
            <h4>Selected: <span class="text-primary"><?php if(ISSET($_POST['search'])){echo date("F", mktime(null, null, null, $_POST['month']));}?></span> <span class="text-primary"><?php if(ISSET($_POST['search'])){echo $_POST['year'];}?></span></h4>

                        <th>Data Joined</th>
                    </tr>	
                </thead>
                <tbody>
                    <?php include'search.php'?>
                </tbody>
            </table>
        </div>
    </div>
</body>	
</html>

Creating the Main Function

This code contains the main function of the application. This code will select a specific MySQLi table row when the button is clicked. To make this just copy and write these block of codes below inside the text editor, then save it as search.php

<?php
    require'conn.php';
 
    if(ISSET($_POST['search'])){
        $month=$_POST['month'];
        $year=$_POST['year'];
        $query=mysqli_query($conn, "SELECT * FROM `member` WHERE month(date_joined)='$month' AND year(date_joined)='$year'") or die(mysqli_error());
        while($fetch=mysqli_fetch_array($query)){
            echo "<tr><td>".$fetch['firstname']."</td><td>".$fetch['lastname']."</td><td>".$fetch['date_joined']."</td></tr>";
        }
    }else{
        $query=mysqli_query($conn, "SELECT * FROM `member`") or die(mysqli_error());
        while($fetch=mysqli_fetch_array($query)){
            echo "<tr><td>".$fetch['firstname']."</td><td>".$fetch['lastname']."</td><td>".$fetch['date_joined']."</td></tr>";
        }
    }
?>
