How To Use Bootstrap Datepicker in PHP & MySQL using Ajax

Originally posted @ https://codeanddeploy.com visit and download the sample code: https://codeanddeploy.com/blog/php/how-to-use-bootstrap-datepicker-in-php-mysql-using-ajax

In this tutorial, I will explain how to implement Bootstrap Datepicker in PHP & MySQL using Ajax. I will guide you step by step on how it works. So in this example, we will create a function that asks the users about their date of birth.

With the help of Bootstrap Datepicker, we enable a quick process with an excellent user interface instead of doing it from scratch or just using the native date picker on chrome which doesn't support other browsers.

So before we continue in this tutorial, I will let you know that we are using Bootstrap 4, jQuery 3.5.1, and Bootstrap Datepicker.

Index.html File

Here is the complete source code of our index.html

Script.js File

Next, our javascript called scripts.js from the imported the above code. Kindly check each line's comment for you to understand the process.

$(document).ready(function() {

    // Initialize the datepicker
    $('.date').datepicker({
        todayHighlight: true, // to highlight the today's date
        format: 'yyyy-mm-dd', // we format the date before we will submit it to the server side
        autoclose: true //we enable autoclose so that once we click the date it will automatically close the datepicker
    }); 

    $("#btnSubmit").on("click", function() {
        var $this           = $("#btnSubmit"); //submit button selector using ID
        var $caption        = $this.html();// We store the html content of the submit button
        var form            = "#form"; //defined the #form ID
        var formData        = $(form).serializeArray(); //serialize the form into array
        var route           = $(form).attr('action'); //get the route using attribute action

        // Ajax config
        $.ajax({
            type: "POST", //we are using POST method to submit the data to the server side
            url: route, // get the route value
            data: formData, // our serialized array data for server side
            beforeSend: function () {//We add this before send to disable the button once we submit it so that we prevent the multiple click
                $this.attr('disabled', true).html("Processing...");
            },
            success: function (response) {//once the request successfully process to the server side it will return result here
                $this.attr('disabled', false).html($caption);
                // We will display the result using alert
                alert(response);
            },
            error: function (XMLHttpRequest, textStatus, errorThrown) {
                // You can put something here if there is an error from submitted request
            }
        });
    });


});

Creating Database Table

Next, creating our database table. If you already created your database then we will continue to create our table "dob" as your table name. Here is the code below.

CREATE TABLE `dob` (
  `id` int(11) NOT NULL,
  `dob` date NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

Process.php File

Next, our last code to process the saving of submitted data from our from.

<?php
    $request = $_REQUEST; //a PHP Super Global variable which used to collect data after submitting it from the form
    $date = $request['date-of-birth']; //get the date of birth from collected data above

    $servername = "localhost"; //set the servername
    $username = "root"; //set the server username
    $password = ""; // set the server password (you must put password here if your using live server)
    $dbname = "demos"; // set the table name

    // Create connection
    $conn = mysqli_connect($servername, $username, $password, $dbname);
    // Check connection
    if (!$conn) {
      die("Connection failed: " . mysqli_connect_error());
    }

    // Set the INSERT SQL data
    $sql = "INSERT INTO dob (dob)
    VALUES ('".$date."')";

    // Process the query so that we will save the date of birth
    if (mysqli_query($conn, $sql)) {
      echo "New record created successfully.";
    } else {
      return "Error: " . $sql . "<br>" . mysqli_error($conn);
    }

    // Close the connection after using it
    mysqli_close($conn);
?>
Enter fullscreen mode Exit fullscreen mode

Now you can enable to save data from the form with bootstrap datepicker using PHP and MySQL with Ajax.
