How to Integrate MySQL Inserts with PHP and jQuery/AJAX for a Seamless Form Submission Experience?

Integrating MySQL Inserts with PHP and jQuery/AJAX

Challenge: Implementing an ajax-driven form that seamlessly inserts data into a MySQL database.

Solution:

1. HTML Form: Create a simple form with a textbox, label, and submit button.
2. jQuery Script:

<code class="javascript">var ajaxSubmit = function(formEl) {
  var url = $(formEl).attr('action');
  var data = $(formEl).serializeArray();
  $.ajax({
    url: url,
    data: data,
    dataType: 'json',
    success: function() {
      if(rsp.success) {
        alert('form has been posted successfully');
      }
    }
  });

  // Prevent default form submission
  return false;
}</code>

3. process.php Script: Establish a database connection and handle form data:

<code class="php">$val = mysql_real_escape_string(post('my_value'), $cxn);
$sql = sprintf("INSERT INTO %s (column_name_goes_here) VALUES '%s';",
                'table_name_goes_here',
                $val
);
$result = mysql_query($sql, $cxn);
$resp = new stdClass();
$resp->success = false;
if($result) {
    $resp->success = true;
}
print json_encode($resp);</code>
