How To Post Data To A Backend Server To Store Into Database?

September 30, 2023 Post a Comment

I want to store below div data into my database.

This is a simple text

Give me any example how I can POST this data in

Solution 1:

You can use XMLHttpRequest to communicate with servers.

Use XMLHttpRequest (XHR) objects to interact with servers. You can retrieve data from a URL without having to do a full page refresh. This enables a Web page to update just part of a page without disrupting what the user is doing. XMLHttpRequest is used heavily in AJAX programming.

Here is an example

// Read your data inside the HTML DIV using the IDvar content = document.getElementById('myContent').innerHTML;
// Add the contents to the object which you want to send to the backendvar data = { "myContent": content };

var xmlhttp = newXMLHttpRequest();   // new HttpRequest instance var theUrl = "/json-handler"; // The backend URL which expects your data
xmlhttp.open("POST", theUrl);

// Set the request format
xmlhttp.setRequestHeader("Content-Type", "application/json;charset=UTF-8");

// JSON encode the data by stringifying it before sending to the server
xmlhttp.send(JSON.stringify(data));

Solution 2:

let myData=$('#myContent').html();
    $.ajax({
            method:'POST',
            url : 'put your file path where do want to handle data',
            data:{
                'data':myData 
                },
            success:function(returnMsg){
            console.log("Success Msg",returnMsg)
            }
        })

Solution 3:

You would need to:

Extract the data from the div using JavaScript
Include it in your POST request.
Catch and handle the request in PHP to store it in the Database.

Example:

This is a single PHP file sample (without full page refresh), but you may need to change the part DATABASE_NAME_HERE and also root (which is the user-name).

<?phpif (isset($_POST['submit'])) {
  // Escape possible HTML tags:$content = htmlspecialchars($_POST['myContent'], ENT_QUOTES | ENT_SUBSTITUTE);

  // Database connection.$db = new PDO('mysql:dbname=DATABASE_NAME_HERE', 'root', '');
  $db->query('CREATE TABLE IF NOT EXISTS `my_table` (id INTEGER PRIMARY KEY AUTO_INCREMENT NOT NULL, text VARCHAR(1024))');

  // Storing new record.$query = $db->prepare('INSERT INTO my_table VALUES (NULL, :text)');
  $query->bindValue(':text', $content);
  if ($query->execute()) {
    $response = 'Successfully stored: ' . $content;
  }
  else {
    $response = 'Error: ' . join(' ', $query->errorInfo());
  }

  exit($response);
}
?>

<!DOCTYPE html>
<html lang="en">
<head>
<title>My title</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
  $(document).ready(function(){
    $('form#my_form_id').submit(function(e) {
      e.preventDefault();

      const content = $('#myContent').text();
      $.post('#', {submit: true, myContent: content}, function(response) {
        alert(response);
      });
    });
  });
</script>
</head>
<body>

<div id="center" style="text-align: center; margin-top: 150px;">
    <div id="myContent" contenteditable="true">This is simple text</div>

    <form id="my_form_id">
        <input name="username">
        <input type="submit" name="Send">
    </form>
</div>

</body>
</html>

Note: if you want to store the entire HTML of the div and not just its text in above:
Change the part $('#myContent').text() to $('#myContent').html().
Remove the htmlspecialchars(...) method usage (e.g. $content = $_POST['myContent'];).

Solution 4:

You need use AJAX send your data (if you need more info, see it: Introduction to Ajax - IBM)

so:

Get your DOM data -- use javascript code;
Send your data to server API;
Server save the data.

xmlHttp / jQuery AJAX / Axios / etc. you can choice anyone AJAX tool.

Solution 5:

HTML

<div id="myContent" contenteditable="true">This is a simple text</div>

Jquery :

var data = $("#myContent").html();
var url = "--your url here--";
$.post(url,
  {
    html: data
  },
  function(data, status){
    alert("Data: " + data + "\nStatus: " + status);
});

PHP

$db = mysqli_connect("localhost", "dbusername", "dbpass", "dbname");
$html_data = mysqli_real_escape_string($db, $_POST["html"]);
mysqli_query($db, "INESRT INTO MYTABLE(html_data) VALUES('$html_data')");
